Chandra Daya Investasi | Clean Water Treatment for Industry: Methods and Stages

Clean water is a core requirement for various sectors, both domestic and industrial. Clean water for industrial use is used in operational processes and machine washing. It must meet certain standards to prevent damage to the machines.

This article discusses clean water treatment for industrial needs. So, read this article to find more information!

Why Is Clean Water for Industry Important?

The industrial sector, especially the manufacturing industry, is one of the largest clean water consumers globally. It is crucial to make sure that the clean water standards for industry are fulfilled.

The standard quality of water for industry and companies in Indonesia is regulated by Indonesia’s Minister of Health Regulation Number 2 of 2023. It states that anyone responsible for the environment, including industry, is obliged to provide water that meets health requirements.

Boilers, cooling systems, and raw water for auto component manufacturers are a few examples of clean water use in the industrial sector.

Generally, clean water management for industry involves conditioning water by reducing or eliminating certain characteristics. It can be achieved by removing dissolved gases, adjusting the pH according to water quality standards, demineralization, and disinfection.

Clean water management in the industrial sector is carried out with the following objectives:

Reducing equipment damage: Water containing solids or other impurities can damage machines or impair their performance, thereby impacting production flow.
Preventing machine corrosion: Impurities in water and mineral residues can accumulate on machines, causing corrosion. Untreated scale can lead to rust, machine damage, leaks, and other problems that can reduce machine performance efficiency.
Maintaining health and safety: Bacterial-contaminated water can pollute manufactured goods or make workers ill. Therefore, water must be clean, safe, and healthy.
Improving operational efficiency and saving costs: Machines can function correctly, less prone to errors, and need less maintenance when the water used is clean and complies with regulations. This can certainly save on operational costs.

Clean Water Treatment Methods for Industry

To obtain clean water for industry, you can choose one of the following methods according to your company's needs:

1. Filtration

Filtration is a clean water treatment method that aims to remove impurities and particles from water. Currently, there are various water filtration techniques, such as nanofiltration and ultrafiltration.

Nanofiltration involves membranes with very small pores that can filter out nano-sized contaminants, such as certain types of bacteria and viruses.

Nanofiltration can also filter organic ions, inorganic ions, and heavy metals. As a result, this method is suitable for treating drinking water.

Meanwhile, ultrafiltration utilizes membranes with larger pores than nanofiltration. Its function is to filter larger contaminants, such as microorganisms and sediments. This method is typically used for wastewater treatment.

2. Reverse Osmosis (RO)

Reverse osmosis (RO) is another modern water treatment method that is widely used in industry. RO uses semi-permeable membranes to capture ions, minerals, and contaminants. This results in very pure water.

3. Electrocoagulation

To remove heavy metals, you can use the electrocoagulation method. It utilizes electricity to remove contaminants regardless of the chemical substances.

4. Sedimentation

Sedimentation is a crucial method in the clean water treatment process for industrial purposes. This method settles contaminants at the bottom of the container, separating them from the water. Sedimentation can reduce water turbidity and improve the efficiency of subsequent water purification methods.

5. Ion Exchange

This method removes harmful and unnecessary ions for industrial processes and replaces them with ions more suitable for those processes. Typically, it uses a special resin.

6. Coagulation and Flocculation

Coagulation and flocculation are used to remove pollutants and microorganisms from water. To do this, you can add a coagulant or flocculant chemical. The coagulant causes the contaminants to group when combined with water, which facilitates their removal.

Clean Water Treatment Process for Industry

The clean water treatment for industry takes place in several stages, including:

1. Filtration

Water is filtered to remove dirt, sand, and solids. Commonly used methods are sedimentation, flocculation, and filtration.

2. Primary Treatment

This treatment removes pollutants that still pass through the filtration process. At this stage, advanced sedimentation or separation using gravitational force can be carried out.

3. Secondary Treatment

Organic substances will be removed biologically during secondary treatment. This method can use microorganisms, oxygen to support microbial growth, and a combination of biological treatment and membrane filtration.

4. Tertiary Treatment

It uses chemicals or sunlight to clean up any residual impurities. In addition to chemicals, you can also use advanced filtration methods, reverse osmosis, or activated carbon filtration.
