Sewage Plant

SEWAGE TREATMENT PLANT (STP) MANUFACTURERS

Sewage is the waste generated from residential, institutional, commercial and industrial establishments. STP plant treats the sewage to make it fit for safe disposal, agricultural use or domestic use in toilets etc. Sewage usually contains a high quantity of organic and inorganic wastes. It is essential to treat sewage before it enters into any water body. If sewage, is allowed to enter the water sources without treatment, it will contaminate them; which is why it is essential to treat sewage properly before letting it into rivers or any other sources of water.

SEWAGE TREATMENT TECHNOLOGIES

• Activated Sludge Process (ASP)
• Sequential Batch Reactor (SBR)

Activated Sludge Process (ASP)

• An activated sludge plant essentially consists of the following:

1) Aeration tank containing microorganisms in suspension in which reaction takes place.

2) Activated sludge recirculation system.

3) Excess sludge wasting and disposal facilities.

4) Aeration systems to transfer oxygen

5) Secondary sedimentation tank to separate and thicken activated sludge.

Sequential Batch Reactor (SBR)

• Sequential Batch Reactor is true batch process where fill, aeration, settle and decant steps are carried out in sequence of batches in a single basin.
• Screened, de-gritted sewage is fed into the SBR Basins for biological treatment to remove BOD, COD, Suspended Solids, Biological Nitrogen and Phosphorous.
• SBR process shall work on batch mode in single step.
• It performs biological organic removal, nitrification, de-nitrification and biological phosphorous removal.
