Abstract
A system for enhancing an activated sludge process including at least one biological reactor. A weighting agent impregnation subsystem is coupled to the biological reactor for mixing biological flocs and weighting agent to impregnate the weighting agent into the biological flocs to form weighted biological flocs. A weighting agent recovery subsystem is configured to recover the weighting agent from the weighted biological flocs and reintroducing the recovered weighting agent to the weighting agent impregnation subsystem.
Claims33
A system for providing a treated effluent comprising:
- a biological reactor comprising at least one sequencing batch reactor connected to a source of wastewater;
- a weighting agent impregnation tank connected to a first outlet and an inlet of the biological reactor;
- a source of a weighting agent connected to an inlet of the weighting agent impregnation tank;
- and
- a separator connected to a second outlet of the biological reactor and an inlet of the weighting agent impregnation tank.
A system for providing a treated effluent comprising:
- a biological reactor connected to a source of wastewater;
- a weighting agent impregnation tank connected to a first outlet and an inlet of the biological reactor;
- a source of a weighting agent comprising a weighting agent storage tank, the source of weighting agent connected to an inlet of the weighting agent impregnation tank;
- a separator connected to a second outlet of the biological reactor and an inlet of the weighting agent impregnation tank;
- and
- a weighting agent feeder subsystem comprising a pneumatic feeder subsystem, the weighting agent feeder subsystem connected to an inlet of the weighting agent impregnation tank, and the pneumatic feeder subsystem comprising a porous media disposed on at least a portion of an inside surface of the weighting agent storage tank.
