Dalam dunia pengolahan air industri dan sistem boiler, keberadaan oksigen terlarut (dissolved oxygen) bisa menjadi musuh utama. Tanpa penanganan yang tepat, oksigen dapat menyebabkan korosi pada pipa, peralatan, dan sistem distribusi air. Salah satu solusi paling efektif untuk mengatasi masalah ini adalah dengan menggunakan oxygen scavengers.
Apa Itu Oxygen Scavengers?
Oxygen scavengers, atau penghilang oksigen, adalah bahan kimia yang digunakan untuk menghilangkan oksigen terlarut dari air atau cairan proses lainnya. Oksigen terlarut dalam air dapat mempercepat proses oksidasi dan korosi, terutama dalam sistem tertutup seperti boiler, sistem pendingin (cooling system), atau dalam pengemasan makanan dan farmasi.
The use of oxygen scavengers is very important to:
- Prevent corrosion in boiler and pipe systems.
- Reduce the risk of damage to expensive and critical equipment.
- Extend the operational life of the system.
- Reduce maintenance costs and downtime.
- Ensure the efficiency of the heating and water treatment system as a whole.
Lautan Air Indonesia understands how important it is to maintain industrial water quality so that the system runs optimally and efficiently. Therefore, we offer a variety of chemical solutions including high-quality oxygen scavengers that have been proven reliable for various industrial needs.

Types of Oxygen Scavengers
There are several types of oxygen scavengers that are commonly used in industry. The choice depends on the system used, operating temperature, pH, and overall process needs.
Here are some of the main types of oxygen scavengers:
1. Food Grade Oxygen Scavengers
Food-grade oxygen scavengers are usually used in applications related to the food, beverage, pharmaceutical, and drinking water industries. These materials must meet strict safety standards and do not produce hazardous substances that can contaminate the final product.
Sodium Sulfite (Na₂SO₃)
One of the most widely used oxygen scavengers in various sectors, including the food and drinking water industries, because it is available in food-grade variants.
Kelebihan:
- Approved for food contact applications in certain concentrations.
- Reactive and effective in binding dissolved oxygen in the system.
- Stable at low to medium temperatures.
Technical Notes:
- Sodium sulfite can produce solid residues in the system, so it is necessary to carry out routine control and blowdown on systems such as boilers.
- Although food grade, its use must still follow the appropriate dosage and procedures so as not to impact the quality of the final product.
Aplikasi:
- Food and beverage industry.
- Steam boiler systems in the food production process.
- Drinking water systems (within the limits set by water quality standards).

2. Non-Food Grade Oxygen Scavengers
Non-food grade oxygen scavengers are generally used for heavy industrial applications, such as power plants, oil and gas, chemicals, and high-pressure boiler systems. These materials are not recommended for use in processes related to food, but have advantages in terms of effectiveness and stability under extreme conditions.
Carbohydrazide
Is a popular alternative to hydrazine because it is safer for the environment and occupational health, but remains very effective.
Kelebihan:
- Effectively removes oxygen without forming solid deposits (does not produce solids).
- Stable at high temperatures and pressures.
- Forms a protective film on metal surfaces, thus helping to proactively prevent corrosion.
Technical Notes:
- Not food grade, therefore should not be used in systems that come into contact with food, beverages, or drinking water.
- Precise dosage measurement is required for optimal performance and to avoid side effects in the system.
Aplikasi:
- High-pressure boiler systems in the general industrial sector.
- Petrochemical plants, pulp and paper, and power plants.
