Effective water management starts with understanding two critical quality parameters: TDS and TSS. Many industries experience equipment damage, rising operational costs, or environmental compliance issues simply because these two indicators are not properly controlled. This article explains the differences between TDS and TSS and provides practical steps to manage them based on real operational needs.
Lautan Air Indonesia, with more than four decades of water treatment experience, supports industries in managing TDS and TSS through complete chemical, equipment, and monitoring solutions.
The Difference Between TDS and TSS
Although TDS and TSS are often mentioned together, they refer to two very different characteristics of water.
What is TDS
TDS or Total Dissolved Solids refers to dissolved substances in water. These include salts, minerals, and organic molecules. TDS particles are smaller than 2 microns, which means they cannot be removed with simple filtration.
Common sources of TDS include:
- Dissolved minerals such as calcium, magnesium, sodium
- Industrial discharge and chemical runoff
- Fertilizers and pesticides
- Geological formations like limestone or shale
High TDS can affect taste, color, and conductivity. In industrial systems, high TDS contributes to scaling, corrosion, and reduced equipment performance.
What is TSS
TSS or Total Suspended Solids refers to particles that are not dissolved. These include silt, clay, organic matter, sand, and microorganisms. TSS particles are larger than 2 microns and can be removed with filtration.
High TSS causes:
- Turbid and cloudy water
- Blocked pipes and pumps
- Reduced efficiency of disinfection
- Disruption of wastewater treatment processes
Both TDS and TSS affect system reliability, but each requires different treatment methods.

Why Managing TDS and TSS Matters
Uncontrolled TDS and TSS levels can lead to operational losses and regulatory violations.
Risks from High TDS
- Scale formation inside boilers, heat exchangers, and cooling towers
- Corrosion of pipelines and storage tanks
- Lower product quality for industries with high purity requirements
Risks from High TSS
- Increased maintenance due to clogged filters
- Higher energy consumption in pumping systems
- Environmental impact due to sediment and oxygen depletion
Managing both parameters is essential for efficient and sustainable water use.
How to Manage and Control TDS and TSS
Managing TDS and TSS starts with accurate measurement followed by the selection of the right treatment method.
1. Monitoring and Measurement
Reliable monitoring helps detect early changes in water quality.
TDS is measured using:
- Conductivity meters
- Gravimetric analysis after evaporation
TSS is measured by:
- Filtering a known water volume
- Drying and weighing the residue
Routine monitoring ensures system stability and prevents water quality excursions.

2. Treatment Methods for TDS
TDS requires advanced separation processes because the particles are dissolved. Effective methods include:
- Reverse Osmosis (RO): Separates dissolved solids through a semipermeable membrane. RO is widely used in industrial water production.
- Ion Exchange: Replaces unwanted ions such as calcium and magnesium. Commonly used in boiler feedwater and softening systems.
- Electrodialysis: Suitable for applications that need high purity water with controlled ion composition.
These processes can be combined depending on water quality targets.
3. Treatment Methods for TSS
TSS removal focuses on filtration and solid separation.
- Clarifiers: Encourage particles to settle through sedimentation.
- Deep Filtration: Uses media such as silica sand, anthracite, or catalytic media to trap suspended solids.
- Coagulation and Flocculation: Uses chemicals like PAC, ACH, or polymer flocculants to bind fine particles into larger clusters.
- Membrane Filtration or Ultrafiltration: Used when very low TSS is required, especially in wastewater treatment.
