Sewage Treatment Plants & Systems based on the latest technology of Extended Surface Aeration Technology as well as with conventional methods for Residential colonies, Hospitals, Hotels, Cities, etc. Using this technology, we offer zero discharge/partial discharge and complete/partial recycle system for colonies, Hospitals, Cities etc. The sludge generation is quite low and overcomes the demerits of the conventional systems. The sewage is collected in a tank, called sewage sump or sewage collection tank. In case septic tank already exits, it can be used as sewage sump. The sewage from sump will then constantly pumped into Packaged Domestic Sewerage Treatment Plant (PDSTP) by employing sewage lift pumps at a constant flow rate. PDSTP is of modular construction and comprises of Bar Screen, Collection Tank, Grit Chamber, Aeration Section – Fludised Aerobic Bed (FAB Reactor), Sedimentation Section (Tube Settler), Chlorine Contact Chamber and Treated Sewage Holding Chamber and Pressure Sand, Activated Carbon filter for fine filtration generating water suitable for auxiliary Application.
