How do Sewage Treatment Plants Work?

Ever wondered Where Does the Waste go after a Simple Flush?

It goes to the sewage treatment plant and if it didn’t a lot of things would occur like for instance the ground water wouldn’t be reusable, the lakes will become contaminated and there would be heaps and heaps of solid waste all across town if there was no Sewage Treatment Plant in place.

Your Sewage Should be Treated and here’s Why!

The importance of sewage treatment plant design is to withhold all the solids as much as possible and before the leaving water called an effluent is discharged to the environment. The solid matter decays it uses oxygen that are needed by the water plants and animals.

Water Recycle 

With the ongoing water scarcity in cities and towns the only way ahead to treat the sewage water by sewage treatment  plant so that the non-hazardous water can be reused to increase the surface water or recharge the ground table water.

How does a Sewage Treatment Plant Work?

Sewage Treatment works in four different methods first the waste goes through the initial process called the preliminary method where most of the course solids are removed. This process includes large filtering screens these help in removing solid objects.

1. Primary treatment

After which the sewage passes to the primary treatment where 60 percent of loose solids are removed as they sink to the bottom only the water oil grease and water remain afloat. This phase removes at least 60 percent of loose solids.

2. Secondary treatment

When the wastewater comes to the secondary phase the Effluents are treated further to remove dissolve suspended biological matter. The secondary treatment uses sedimentation and biological sludge. This treatment requires a separation process to remove the micro-organisms to then release it to tertiary stage of treatment.  

3. Tertiary treatment 

In the last and final stage the water goes to filters again to remove more waste if any found lingering from the secondary treatment. The wastewater then is disinfected chemically either through micro-filtration which filters the water completely before releasing it to the seawater, lakes or ponds.
