SeqtreaT (Sequential Batch Reactor Technology) is one of the most advanced sequential batch reactors developed by Thermax for wastewater treatment. SeqtreaT accomplishes equalisation, aeration and clarification in timed sequence batch modes, especially for domestic wastewater – all in a single reactor basin. Also, the cycle time of treatment of batches can be optimised to suit variations in loads. Aerobic phase and controlled anoxicphase are used to reduce organics to suit variations in loads, as well as nitrogen and phosphorus compounds.
