what is sewage treatment plant.
Sewage waste water and waste matter from the town is collected in sewage treatment plant where the sewage is processed. The processing of sewage is done in following steps
1 Removal of greed and pebbles:
The heavy particles of grit and pebbles, including sand settle down at the bottom. It is then removed from time to time. A simple way to separate grit is by canalysing sea beach from a lower level to higher level.
2 How to separation of non-biodegradable matter from sewage:
Semisolid sewage is passed through a screen of vertical bars to screen out the plastic, can, and Rag including napkin etc.)
3 Function of cum aeratoion tank:
Screened is then passed into the shedder tank were the contents churned. Churning the contents to make a paste like matter and also adds air to eat mixing air activate aerobic microbes bacteria and fungi which start growing into the waste matter.
4 function of sedimentation or settling tank:
Churned sewage is passed into the sedimentation tank in which the solid part of the sewage is made to stand. It settle down as large and the waste water overflow drain or pipe for use in irrigation field farm land the wastewater along with floating scum. is full of nutrients minerals for the plants and hence help healthy growth of plant on the farms.
function of digestor:
From settling tank the semi-solid of sludge is pumped into a digester. The anaerobic microbe are activated in the digestive, which convert the organic Waste food into manure releasing fuel gas fullstop fuel gas is formed to The Homes factories and other place where it is used as fuel. The the large is passed out into the open field where it is dry in Sun. This convert the sludge into dry manuar. My new is carried to the form and field.
