Abstract
A biological wastewater treatment system includes an equalization tank for sending a defined first portion of the wastewater to a submerged membrane filter. When the quantity of the received wastewater exceeds the defined first portion, a second portion of wastewater, formed from the wastewater that exceeds the defined first portion, is sent to a filtration process. The filtration process includes adding a flocculating agent to the second portion entering filtration, filtering the second portion, thereby producing retentive waste including flocculated material, and then sending the retentive waste to the submerged membrane filter.
