Package STP (Sewage Treatment Plant)
WAPP has developed & launched small capacity skid mounted type package STPs based on SBR technology in Basic &Premium range (Plants requires Minimum manpower.)
- These STPs are suitable for pumped flow and can be installed on ground or terrace. It is a single unit consisting of biological reactor with all accessories and a filter for polishing of treated water.
- Available range:–2 – 50 KLD in single tank & upto 100 KLD in 2 tank configuration.
- System can be with or without tertiary treatment, depending upon treated water utility
- Tanks in MS/FRP/MS FRP/HDPE.

We have Basic & Premium package STP plants:
|BOD||Up to 250||<20 ppm||<20 ppm|
|TSS||Up to 250||<30 ppm||<20 ppm|
|COD||Up to 600||<75 ppm||<20 ppm|
- Basic Package STP:- Secondary Sewage treatment package w/o tertiary (optional) & mechanical sludge de-watering system.
- Premium Package STP:- Complete sewage treatment package with tertiary treatment (Ozonization, filtration etc.) high degree of automation & mechanical sludge de-watering system
Water filled in the reactor by a specially designed distribution header for complete mixing of sewage into sludge blanket.
Aeration is provided by submerged diffuser with the help of air blowers.
WappSys OXY-BIO incorporates the engineered decanting system. Decanter designed to achieve the desired efficiency.
A tank may have one or two decanting systems as per the requirement. Baffle plates attached on both sides of decanter to prevent any scum flow with treated water.
Aeration system designed on the peak load during dry seasons. The operational cycle selected to ensure adequate filling, Aeration settling and decanting to achieve desired quality of treated water. Aeration time selected to fulfill the oxygen requirement to survive biological mass as well as oxidation of organic compounds and nitrogen. Generally aeration time selected as 1.5-2.5 hours as per the BOD load and MLVSS present in the tank.
Settling time selected for proper settling of biomass to obtain desired depth of clear supernatent, which can decanted in decant phase. Generally 45 minutes of settling time required to obtain clear supernatant layer of desired depth.
Decanter designed for 0.75 hours of descanting time. Decanting can started in between the settling phase if sludge level is sufficiently below the clear water layer.
Decanted water is then filtered through a UV Filter for disinfection.
