Sewage Treatment or Domestic Waste Water Treatment
It is the process of removing contaminants from wastewater both run off(effluent) and domestic. It includes physical, chemical and biological process to remove physical, chemical and biological contaminants, make water suitable for safe discharge into environment or reuse and recycle.
Typically sewage treatment involves three stage of treatment-Primary, Secondary and Tertiary treatment. First, the solids are separated from the wastewater stream. Then dissolved biological matter is progressively converted into a solid mass by using indigenous, water-borne microorganisms by aerobic or anaerobic biological process. Finally, tertiary treatment involves removing fine particles, objectionable odours harmful bacteria by filtration followed by disinfection thus making waste water suitable for reuse and safe handle viz., gardening, flushing toilets or any other non-potable use.
We, at ARIPRA offer following biological plants viz.,
- Extended Aeration System (EAS) – conventional method.
- Sequential Batch Reactor (SBR) – by using decanter principle.
- Moving Bed Biological Reactor (MBBR) – by using fluidized advanced high surface area to volume ratio bio-media.
- Membrane Bio Reactor (MBR)
- UASB systems
- Fixed Biological Reactor (FBR) – by using corrugated fixed media.
