What is Wastewater Treatment

Wastewater treatment is the process of converting wastewater (water that is no longer needed or suitable for use) into bilge water that can be discharged back into the environment. Wastewater is full of pollutants, including bacteria, chemicals and other toxins. Its treatment is designed to reduce pollutants to acceptable levels so that the water can be safely discharged back into the environment.

step-by-step wastewater treatment process

1. Wastewater collection

This is the first step in the wastewater treatment process. Municipalities, homeowners and business owners have all set up collection systems to ensure all wastewater is collected and directed to a central point. This water is collected and channeled to a treatment plant using an underground drainage system or an exhaust track owned and operated by a merchant.

2. Primary processing

The process involves the separation of long-lived solids from wastewater. Primary treatment involves pouring wastewater into large tanks, allowing solids to settle on the tank surface.

3. Secondary processing

Also known as the activated sludge process, the secondary treatment stage involves adding seed sludge to wastewater to ensure its further breakdown. Air is first pumped into huge aeration tanks that mix wastewater with seed sludge, which is basically a small amount of sludge that encourages the growth of bacteria that use oxygen and other small microbes that consume the remaining organic matter.

4. Biosolids handling

The solid matter precipitated out after the primary and secondary treatment stages is directed to the digester. The cooker is heated at room temperature. The solid waste is then treated for one month, followed by anaerobic digestion.

5. Disinfection

After the primary treatment stage and the secondary treatment process, there are still some pathogenic organisms in the remaining treated wastewater. To eliminate them, wastewater must be sterilized in a tank containing a mixture of chlorine and sodium hypochlorite for at least 20-25 minutes. The disinfection process is an integral part of the treatment process as it protects the health of animals and local people who later use the water for other purposes.

6. Sludge treatment

Sludge produced and collected during primary and secondary treatment needs to be thickened and thickened for further processing. Put it in a thickening tank, allow it to settle, and then separate from the water. This process can take up to 24 hours. The remaining water is collected and sent back to huge aeration tanks for further processing. The sludge is then processed and returned to the environment, where it can be used for agricultural purposes.

Benefits of Wastewater Treatment

Wastewater treatment has many benefits. For example, wastewater treatment ensures that the environment remains clean and free from water pollution.

At this point you probably know how important it is to prevent water pollution. After all, it causes countless diseases in humans and animals. In the worst case, it can even lead to death. Treating wastewater minimizes water pollution, keeping us safe and healthy.

We also applaud this process for its clever use of the most important natural resource; water. Treated water can be used in factory and industrial chillers. It will minimize the need to use fresh water, thus saving water to some extent.
