Dealing with Bad Odors in Raw Water: Challenges and Solutions

In various industries, from manufacturing, food and beverage, to the health sector, water is not just a complement, but a vital component. However, often the quality of raw water does not meet the expected standards, one of which is indicated by an unpleasant odor that is disturbing.

The problem of odor in raw water is not just a matter of comfort. This is an indicator of biological or chemical contamination which, if not handled properly, can disrupt the production process, reduce product quality, and create negative perceptions from consumers towards your brand.

The Impact of Bad Odors in Raw Water

A strange odor in raw water indicates that the water is not naturally clean, and potentially contains hazardous substances. Some of the impacts that can arise include:

1. Decrease in the Quality of the Final Product

The food, beverage and cosmetic industries are highly dependent on water quality. Odors in water can alter the taste, aroma or stability of a product. Consumers will immediately notice a difference in quality, even if there is only a small sensory change.

2. Disruption in the Production Process

Water odor is generally related to the presence of complex organic compounds, microorganisms, or gas compounds such as H₂S. These substances can interfere with chemical reactions, fermentation, or sanitation processes that require stable water conditions.

3. Increases the Risk of Corrosion and Fouling

Some odor-causing substances such as sulfur compounds, iron, and manganese can trigger corrosion in pipes and industrial equipment. In addition, the accumulation of organic materials in the piping system also accelerates fouling, thereby reducing the overall efficiency of the system.

4. Difficulty Meeting Regulatory Standards

Smelly water indicates that there are water parameters that exceed safe limits, such as Chemical Oxygen Demand (COD), Total Organic Carbon (TOC), or microbes. This makes it difficult for industries to meet industrial water quality standards, SNI, or even certain export standards.

5. Affect the Company’s Image

Especially in the hospitality industry such as hotels, restaurants, and hospitals, the smell of tap water or bathrooms will immediately create a negative experience for users. In the digital age, customer complaints about water quality can spread quickly and affect the reputation of a business widely.

Causes of Bad Odor in Raw Water

To effectively address odor issues, it is important to understand what causes them. In general, the causes of odor in raw water can be classified into several categories:

1. Activity of Microorganisms

Bacteria, algae, and other microorganisms can produce organic compounds that cause odor, especially in stagnant surface water. The two main compounds are:

Geosmin – Causes an earthy or mossy odor, usually from cyanobacteria.
MIB (Methyl Isoborneol) – Causes a musty or moldy odor, also produced by algae and aquatic microorganisms.

2. Dissolved Gases such as Hydrogen Sulfide (H₂S)

This gas gives a distinctive odor like rotten eggs and is commonly found in groundwater or water that has anaerobic conditions. H₂S appears due to the activity of sulfate-reducing bacteria that thrive in low-oxygen environments.

3. Dissolved Organic Matter

Organic materials such as rotting leaves, moss, and agricultural waste can decompose and produce unpleasant odors. These substances also increase the organic load (COD/TOC) which burdens the water treatment process.

4. Contamination from Industrial or Domestic Waste

Water contaminated with household or industrial waste often carries chemical compounds such as phenol, ammonia, or detergents that produce a sharp, pungent, or even chemical-like odor.

5. Heavy Metals and Minerals

Water with high iron and manganese content can cause a strong metallic odor. In addition, both can stain clothing, equipment, and ruin the aesthetics of the water.

6. Environmental Conditions

Long dry seasons that reduce the volume of river or reservoir water can cause an increase in the concentration of odor-causing compounds. In addition, changes in water temperature also affect the growth of microorganisms.

Odor Treatment Solutions in Raw Water

The problem of odor in raw water cannot be solved with a single solution. An integrated approach is needed that combines source analysis and appropriate treatment strategies. Here are some methods that have proven effective:

1. Water Quality Testing and Technical Consultation

Before determining a treatment system, it is essential to conduct comprehensive laboratory testing, including:

Organic parameters: COD, TOC, BOD
Microbiological content
Dissolved metal and gas content

Lautan Air Indonesia provides complete water analysis services along with technical consulting support to design systems that suit customer specific needs.

2. Aeration System

Aeration is used to remove dissolved gases such as H₂S, enhance oxidation of metals such as iron and manganese, and help control the growth of anaerobic microorganisms. Aeration systems can be designed mechanically or with venturi technology.

3. Ozonization (Ozone Treatment)

Ozon adalah oksidator kuat yang mampu menghancurkan senyawa organik kompleks, membunuh mikroorganisme penyebab bau, serta memperbaiki kualitas warna dan rasa air. Ozonisasi juga tidak meninggalkan residu berbahaya seperti halnya disinfektan kimia.

4. Activated Carbon

Adsorption technology using activated carbon is very effective in removing odor, taste, and color from water. Activated carbon absorbs small organic compounds such as geosmin and MIB.

Lautan Air Indonesia provides various types of activated carbon—granular and powder—based on coconut shells and coal.

5. Coagulation and Flocculation

To handle odors caused by dissolved organic matter, a combination of coagulants and flocculants is needed to precipitate fine particles and odor-causing compounds. Types of coagulants such as PAC, ACH, or Aluminum Sulfate can be used according to water characteristics.

Lautan Air Indonesia has a coagulant plant in Indonesia, ensuring fast distribution and stable supply of water treatment chemicals.

6. Multi-Stage Filtration

The use of layered media filters such as silica sand, anthracite, DMI-65, and activated carbon can filter pollutants physically and chemically. This filtration system can be used as part of a pre-treatment or post-treatment unit.

7. UV Light for Disinfection

UV disinfection is very effective in deactivating bacteria and algae that contribute to odor. This technology does not use chemicals and does not produce harmful by-products.

How to Increase RO Recovery Rate for Optimal Efficiency

Reverse Osmosis (RO) is a water filtration technology that is very effective in producing clean water with high quality. However, one of the main challenges in operating an RO system is the low recovery rate, which is the percentage of raw water that is successfully converted into clean water. If the recovery rate is low, then the volume of water wasted as reject (brine) becomes greater, increasing operational costs and reducing the efficiency of water use.

Many industries and water treatment facilities face this obstacle. They want to increase the recovery rate to optimize raw water consumption and reduce waste disposal costs, but often face various obstacles, such as:

Membrane Fouling – Accumulation of contaminants on the membrane that inhibits its performance.
Scaling – Mineral deposits that reduce the membrane’s filtration capacity.
High Operating Pressure – The higher the pressure required, the higher the energy consumption and operating costs.
Decreased Permeate Water Quality – Indiscriminately increasing the recovery rate can lead to increased TDS and other contaminants in the output water.

Without proper solutions, these issues can result in more frequent downtime, shorter membrane life, and increased operational costs.

Consequences If Recovery Rate Is Not Increased

When the RO recovery rate is not optimized, the negative impact is not only felt in terms of operations, but also in terms of sustainability and regulatory compliance. Some of the negative impacts of a low recovery rate include:

Raw Water Waste – Water purchased or taken from natural sources is not utilized optimally, increasing the consumption of resources that could be minimized.
High Waste Disposal Costs – The more water is discharged as brine, the higher the cost of treatment and disposal.
Poor Energy Efficiency – With low recovery rates, the energy used in the osmosis process is not optimal, significantly increasing electricity costs.
Environmental Impacts – Discharge of liquid waste with high salt concentrations can pollute the environment and contribute to ecological problems.

If companies do not address this issue immediately, operational costs will continue to increase, efficiency will decrease, and the potential for compliance with environmental regulations could be compromised.

Effective Ways to Increase RO Recovery Rate

In order for the RO system to work optimally with a higher recovery rate, here are some solutions that can be applied.

1. Improvement of Raw Water Pretreatment

Fouling and scaling are two major factors that cause a decrease in recovery rate. Therefore, the pretreatment stage should be optimized with the following steps:

Using multimedia filters to reduce suspended solids before entering the RO membrane.
Application of coagulants and flocculants to reduce organic content that can clog the membrane.
Installation of softeners or anti-scalants to prevent scale formation due to calcium and magnesium ions.

2. RO Operation Optimization

A good RO system setup can increase the recovery rate without sacrificing the quality of the resulting water. Some steps that can be taken include:

Adjusting the operating pressure to stay within the optimal range without causing excessive pressure that accelerates fouling.
Monitoring and controlling the flow rate to avoid excessively high ion concentrations in the reject section.
Using a multi-stage RO configuration that allows the reuse of rejects from the first stage to the second stage to increase water separation efficiency.

3. Application of Advanced Technology

With the advancement of technology, there are several innovative methods that can help increase the recovery rate without damaging the membrane:

Membranes with Antifouling Technology – The latest membranes are equipped with a special coating that is more resistant to fouling and scaling.
Energy Recovery Device (ERD) – This device allows the recovery of energy from the reject stream, significantly reducing power consumption.
Continuous Membrane Cleaning (CMC) System – This system allows membrane cleaning without having to shut down, thus reducing downtime and extending membrane life.

4. Scheduled Care and Maintenance

Without proper maintenance, the RO system will experience a drastic decrease in performance. Some suggested maintenance steps are:

Periodic cleaning of membranes with appropriate cleaning agents to remove organic and inorganic deposits.
Monitoring of operating parameters such as pH, pressure, and conductivity to detect problems early.
Routine checks on pumps and valves to ensure there are no leaks or malfunctions that could compromise system performance.

Combating Legionella in Cooling Towers: Maintaining Operational Safety and Efficiency

Cooling towers can be a breeding ground for Legionella bacteria, a dangerous microorganism that thrives in watery environments with temperatures between 20°C and 50°C. If left unchecked, Legionella can spread through aerosols produced by cooling towers and cause serious diseases such as Legionellosis.

Legionella thrive in biofilms and deposits that form inside cooling towers, especially if the water treatment system is not optimal. Factors such as poor water circulation, the presence of organic matter, and inadequate disinfectant levels can accelerate the growth of these bacteria. If a person inhales contaminated water droplets, they can develop Legionnaires’ disease, a severe form of pneumonia that can be fatal.

Legionella Impact: More Than Just a Health Concern

The presence of Legionella in cooling towers is not only a health issue, but can also have a major impact on business operations and regulatory compliance. Here are some of the impacts:

Protecting Boilers by Removing Oxygen from Feed Water

Boiler feed water is a crucial component in steam generation systems, both for industry and power generation. However, one of the biggest challenges in boiler feedwater management is the presence of dissolved oxygen. Although it may seem trivial, oxygen in feedwater can cause serious corrosion to pipes, boilers, and other equipment. This corrosion not only reduces system efficiency but also increases maintenance costs and the risk of equipment failure.

If oxygen is not controlled, the long-term effects can be very detrimental. Metals in the boiler system will oxidize, forming rust and scale that can clog pipes and reduce heat transfer. As a result, energy consumption increases, efficiency decreases, and equipment life is shortened.

Not only that, corrosion due to oxygen can cause pipe leaks that endanger worker safety and disrupt operational continuity. Therefore, removing oxygen from boiler feedwater is not just a recommendation but a mandatory step for industries that rely on boiler systems.

Losses Caused by Oxygen in Boiler Feed Water

Before we discuss solutions, let’s take a deeper look at how oxygen can cause damage.

1. Corrosion on Pipes and Boilers

Oxygen reacts with metals to form ferric oxide (rust) which accelerates material degradation. This corrosion reduces the thickness of the pipe, increasing the risk of leaks that can lead to production and safety losses.

In severe cases, corrosion can cause total failure of the pipe or boiler, forcing an unexpected system shutdown.

2. Crust and Sediment Formation

Iron particles from corrosion will be carried in the water flow and eventually settle in the system. These deposits form scale that reduces heat transfer efficiency, increases fuel consumption, and shortens the operational life of the boiler.

Scale buildup can also cause overheating in certain parts of the boiler which risks damaging the metal structure.

3. Damage to Boiler Components

Valves, pumps, and heat exchangers are some of the components that are particularly susceptible to the effects of dissolved oxygen. Accumulated corrosion can clog water flow paths, reduce system performance, and increase maintenance and replacement costs.

Premature wear on these components can lead to decreased operational efficiency and increased system downtime.

4. Operational Disruption

Uncontrolled corrosion can lead to leaks that require operational shutdowns for repairs. Downtime due to repairs not only results in decreased productivity but also increases overall operating costs.

In some cases, large leaks can cause system failures that endanger workers and the surrounding environment.

With all of these risks, it is clear that removing oxygen from boiler feedwater should be a top priority in industrial boiler system management.

Effective Ways to Remove Oxygen from Boiler Feed Water

Following are some of the main methods used to remove oxygen from boiler feed water:

1. Use of Deaerator

Deaerator is a mechanical equipment specifically designed to remove oxygen and other dissolved gases from boiler feed water. Its working principle is by:

Heating water to near boiling point to release dissolved gases.
Using pressure and steam jets to drive oxygen from the water.
Collecting oxygen-free water ready for use as boiler feed.

Advantages of using a deaerator:

Effectively reduces oxygen levels to below 7 ppb (parts per billion).
Reduces consumption of oxygen-binding chemicals.
Increases boiler operational efficiency.

2. Use of Chemical Oxygen Scavenger

If the installation of a deaerator is not possible or as a complement, the use of oxygen scavenger chemicals is essential. These chemicals react with dissolved oxygen in water and convert it into compounds that are harmless to the boiler system. Some types of chemical oxygen scavengers that are commonly used:

Sodium Sulfite (Na2SO3) – Reacts rapidly with oxygen to form a safe sulfate.
Hydrazine (N2H4) – Effective in high pressure systems and does not produce solids.

Advantages of using chemical oxygen scavenger:

Prevents corrosion by removing oxygen remaining after deaeration.
Easy to apply in various operational conditions.
Effective in boiler systems without deaerators.

3. pH Control and Electrical Conductivity Control

Controlling pH and electrical conductivity (EVC) in boiler water also plays a role in preventing corrosion due to oxygen. A pH that is too low can accelerate the oxidation process, while a high EVC indicates the presence of impurity ions that can worsen corrosion.

Solutions that can be applied:

Adjusting the pH by adding alkali such as sodium hydroxide (NaOH) to keep it in the optimal range (8.5 – 10.5).
Performing periodic blowdown to reduce impurity ions in the boiler water.

4. Regular Monitoring and Analysis

Monitoring the quality of boiler feed water is very important to ensure oxygen remains within safe limits. Some steps that can be taken:

Using a dissolved oxygen (DO) meter to monitor dissolved oxygen levels.
Conducting periodic chemical tests to control the effectiveness of chemical treatment.
Using an automatic monitoring system for faster response to changes in feed water conditions.

Why is the Activated Sludge in Wastewater Treatment Plant Not Sedimenting Properly?

Activated sludge is an important part of the wastewater treatment process in a Wastewater Treatment Plant (WWTP). However, one common problem that is often encountered is that activated sludge does not settle properly. As a result, the quality of the effluent decreases, the suspended solids content increases, and the efficiency of the WWTP system is disrupted.

This phenomenon is often seen from the sludge that remains floating in the clarifier or sedimentation tank, producing turbid effluent that does not meet environmental standards. So, what causes activated sludge not to settle properly? And how to overcome it?

Impact and Causes of Active Sludge Not Sedimenting

When activated sludge does not settle properly, not only is the efficiency of the WWTP affected, but it can also cause serious consequences such as:

Increased Total Suspended Solids (TSS) in the effluent which can cause non-compliance with environmental regulations.
Increased Biochemical Oxygen Demand (BOD) and Chemical Oxygen Demand (COD) which worsen environmental pollution.
Domino effect on downstream processes such as filtration and disinfection, increasing operational costs and the need for additional chemicals.

Some of the main causes of activated sludge not settling properly include:

1. Sludge Bulking

Sludge bulking occurs when microorganisms in activated sludge grow excessively and form flocs that are less dense, making it difficult to settle. The main causes of sludge bulking include:

Excessive growth of filamentous bacteria, especially in conditions with excess carbon or nutrient deficits such as nitrogen and phosphorus.
Suboptimal aeration conditions, either excessive aeration that keeps the sludge floating or insufficient aeration that causes the growth of unwanted microorganisms.
Imbalance in the F/M (Food to Microorganism) ratio, where the amount of organic waste entering does not match the available microbial population.

2. Sludge Pin-Pointing

Sludge pin-pointing occurs when the sludge flocs are too small and not heavy enough to settle properly. This can be caused by:

Too aggressive aeration, which causes the mud floc to break into smaller particles.
Inappropriate coagulant or flocculant dosage, so that the floc is not formed optimally.
Low organic load ratio, which makes the mud lack food substrate to form large flocs.

3. Overloading

If the waste flow to the WWTP exceeds its design capacity, activated sludge may experience disturbances in the settling process. Causes of overloading may include:

Spikes in organic loads due to changes in industrial production.
Extreme pH fluctuations, which disrupt the balance of microorganisms in the system.
Increased oil and grease content, which inhibits sludge flocculation.

4. Unstable Nutritional Quality and pH

Microorganisms in activated sludge require the right balance of nutrients to grow and form good floc. This imbalance can be caused by:

Lack of nitrogen or phosphorus, which causes the sludge to become looser and not settle well.
Too high or too low a pH, which inhibits microbial activity.
Toxic content such as heavy metals or certain chemicals, which kills important microorganisms in activated sludge.

How to Solve the Problem of Unsettled Activated Sludge?

If the activated sludge in your WWTP is not settling properly, there are several solutions that can be applied to return the system to optimal condition:

1. Controlling the Growth of Filamentous Bacteria

If the cause is sludge bulking due to filamentous bacteria, possible solutions include:

Increase the F/M ratio by adjusting the incoming organic load.
Balancing nutrient levels (Carbon (C)/Nitrogen (N)/Phosphorus (P)) so that bacterial growth conditions are more stable.
Using chemicals such as chlorine or hydrogen peroxide to control excessive filamentous bacterial growth.

2. Optimization of Aeration Process

Make sure the aeration is not too excessive or too lacking, adjust it to the needs of the microbes.
Monitor Dissolved Oxygen (DO) regularly to keep it within the optimal range (1.5 – 2.5 mg/L).

3. Proper Use of Coagulants and Flocculants

Application of coagulants such as Poly-Aluminium Chloride (PAC) or flocculants such as anionic/cationic polymers can help improve sludge flocculation.
The dosage must be calculated precisely so as not to cause negative effects such as sludge pin-pointing.

4. Controlling Overloading and Waste Fluctuations

Install an equalization tank to level the waste load before entering the biological system.
Monitor and control the pH to keep it stable in the range of 6.5 – 7.5.
Separate oil and fat before entering the WWTP, using a grease trap or oil skimmer.

5. Adjusting Sludge Age and Wasting Rate

Set the sludge age to remain ideal according to the system design.
Periodically remove excess sludge (sludge wasting) to prevent the accumulation of inactive microorganisms.
