Sewage Treatment Plant

How to Treat Sewage?

Sewage is used water that has been polluted and generated from human activities and also rainwater runoff. it is also known as wastewater. Sewage contains substances, such as food scraps, oils, soaps, chemicals and human waste. In all homes, it includes water from the kitchen, showers, bathtubs, washing machines, dishwashers, and toilets. Industries and businesses also have their share of liquid waste that must be cleared and cleaned before they are directed out to the environment.

The treatment plants produced by By-Jas Engineering can reduce the pollutants in sewage to a level that can be handled by nature. If sewage treatment is not properly done, this can cause many types of diseases. Making water safe for use is a means of caring for our environment and our own health.

Sewage treatment consists of three stages, as follows:

Stage 1 (Preliminary Treatment)

Wastewater enters the plant and large objects, such as plastics, cotton buds, baby wipes, rubbish and rags are removed by the specifically designed filter screens.

Then the wastewater goes through the grit removal tank, where heavy inorganic materials, such as rocks and minerals settle to the tank bottom. The tank is then drained, and the water goes into the next treatment stage.

Stage 2 (Primary Treatment)

The next stage is done at the sedimentation tanks (also called clarifiers and settling tanks). Here, the particles in the water sink to the bottom and form a sludge. Then the sludge is pushed to the end of the tank, by mechanical scrapers and pumped to a treatment area for sludge.

Stage 3 (Secondary Treatment)

At this stage the water is already partially clear, however, some organic matters and dissolved nutrients are still present, so they need to be removed.

The aeration process is done, when air is pumped into the tank to encourage the growth of microbes that form “activated sludge” flocks. They need oxygen, so they can break down the remaining organic materials. This process is an ideal alternative to chemical processing.

Once the activated sludge flocks have finished their job, the water goes to the secondary sedimentation tank, which is the final stage of the sewage treatment and the water can now be safely discharged to the water streams.
