BioCask is a top of the line domestic wastewater solution by Thermax. The innovative design of the BioCask has surpassed the limitations of a conventional wastewater treatment system. The BioCask uses the first-of-its-kind unidirectional fluidization pattern. This pattern ensures efficient oxygen usage so as to promote organic waste decomposition.

Standard Capacities

  • BioCask Mini : 10 KLD and above
  • BioCask : 50, 100, 150, 200, 250 & 300 KLD (modular units for higher capacities)

Salient Features

  • Perfect for basement installation, where height is less than 3 meters
  • Reduced operating costs due to high oxygen transfer efficiency
  • Minimal civil work
  • BOD < 5 mg/l without ultrafiltration


This space and power saving technology is a better alternative to conventional waste water treatment plants. FAB (Fluidized Aerobic Bioreactor Technology)
offers an effective solution to water situation with constraints such as scarcity of open space, network piping issues, high power and land cost.

Standard Capacities

  • Prefabricated : 50,75 & 100 KLD (modular for other capacities)
  • On-Site Fabrication : 10 to 5000 KLD

Salient Features

  • Skid Mounted; Quick & Easy Installation
  • Odorless operation, with a self – regulating system
  • Pre-engineered; Low Cost & Fast Delivery
  • Achieves < 5 TSS mg/l without coagulant, flocculent
  • Achieves < 5 BOD mg/l without UF membranes


SeqtreaT (Sequential Batch Reactor Technology) is one of the most advance technologies developed by Thermax for wastewater treatment. Especially for domestic wastewater, SeqtreaT in a single reactor basin, its achievements are three-fold: equalization, aeration and clarification in timed sequence batch mode.
Also, the cycle time can be used to suit various organic loads. Aerobic phase and controlled anoxic phase are used to reduce organic, nitrogen and phosphorus compounds.

Standard Capacities

  • 10, 20, 30, 50, 100, 150, 200, 250, 300, 350, 400, 500 KLD
  • Customized higher capacities available

Salient Features

  • Novel decanting mechanism developed by Thermax
  • Compact, easy to operate & scalable
  • Nitrogen & Phosphorus removal capability
  • Treated Sewage suitable for recycle & reuse
