Waste Water Treatment

Wastewater treatment is the process of converting wastewater – water that is no longer needed or is no longer suitable for use into bilge water that can be discharged back into the environment . Its treatment aims at reducing the contaminants to acceptable levels to make the water safe for discharge back into the environment.

SEWAGE TREATMENT PLANT                                                            

Waste water may be defined as a combination of the liquid or water carried wastes removed from residences, institutions, commercial and industrial establishments together with such ground water, surface water and storm water. Sewage treatment is the process of removing contaminants from wastewater, primarily from household sewage. It includes physical, chemical and biological processes to remove these contaminants and produce environmentally treated wastewaterter.

Types of Treatment
* Activated Sludge Process (ASP)
* Moving Bed Biofilm Reactor Technology (MBBR)
* Membrane Bio – Reactor Technology (MBR)
* Sequential Batch Reactor Technology (SBR)

INDUSTRIAL EFFLUENT TREATMENT PLANT                            

The Industrial Effluent Treatment Plants involve different stages of treatment including Physico- chemical treatment and biological treatment followed by tertiary treatment. The Treatment system depends on the characteristics of wastewater and treated water quality to be achieved.

Preliminary Treatment
* Screening
* Grit Removal system
* Oil Removal system

Primary Treatment
* Oil Water Separators (OWS)
* Clarification

    Tube Settler
