Sludge is collected and stored collection/ buffer tank for a long period. Sludge disposal can be done when required or as per the guideline given by EcoTec in the operation manual. Each plant is designed with its own sludge holding capacity.

EcoTec plants are designed with sensors that constantly monitor the inflow into the plant. When no or under load is detected, the plant shifts to EcoSave mode where very little aeration is given to maintain the microbe population. When the inflow become adequate a normal treatment mode is activated. This insures the same treatment even at low occupancy period. Most importantly it saves a lot of money for the customer.
