WET STP is compact packaged sewage treatment plant is based on MBBR technology is a durable piece of equipment which is with proper care and maintenance will last for many years. Our Package system is like plug and play type which can handle fluctuating biological load.


  • Robust design made by high quality mild steel material with epoxy paint from inside and outside.
  • Compact design, fraction of the size of conventional system.
  • Capacity can be easily upgraded by simply increasing the fill fraction of biofilm carriers.
  • Actively sloughed biofilm automatically responds to load fluctuations.
  • Operation at higher suspended biomass.
  • High efficiency BOD removal and nitrification (even in low temperature)
  • Low HRT and high Biomass concentration
  • Reduced sludge production as compared with activated sludge process.
  • Low solid loading on solid-liquid separation unit.
  • Non Clogging design.
  • Can be easily retrofitted.
  • Simple in operation, no skilled labor required to operate the plant.
