FRP Industrial Sewage Treatment Plant

Package Sewage Treatment Plant  of Fiber glass reinforced Plastic (FRP) tank made by filament winding process from suitable polyester resin and glass fiber  of the tank with suitable polyester resin and fiber glass to make tank suitable for underground application  process variation. The tank to have three zones first zone to work as anaerobic septic zone created with suitable partition of FRP; second zone to be created by partition of FRP with advanced fab media with a surface area to volume ratio of minimum of 400 Sq. Mtr / Cubic meter suitably encased    free movement of the media within fixed space created by the net; the third zone to work as sedimentation zone in the remainder area of the tank. Aerobic zone have Twin Lobe Air Blowers installed for providing air flow coarse aeration in the zone for speedy reduction of BOD. Sedimentation zone have submersible pump of the  for pumping the activated sludge back to the anaerobic zone by way of PVC pipes  The whole plant to be controlled by automatic control panel made from sheet molded compoundAeration Zone:Second stage is the aerobic zone along with fab media inside the tank which in turn increases the surface area and retains microorganisms long enough to digest the organic substance. clear water overflows to the next treatment chamber. Air is provided through blowers and higher contacting time with the slime on the fab media facilitates efficient digestion. bod removal is around 60%Solid Separation Zone:First stage transforms the effluent solids to settled solids while allowing scum tofloat on the surface; it is a primary sedimentation zone in which settled sludge is stabilized by anaerobic digestion.The treatment efficiency of the chamber is in the range of 30% BOD removal.
