Abstract

Methods and systems of a biosolids concentrator and digester system having an inlet, an equalization/separation tank, an equalization/separation tank-anaerobic tank connector, an anaerobic tank, an anaerobic tank-aerobic tank connector, an aerobic tank, an aerobic tank-clarifier tank connector, and a clarifier tank. The equalization/separation tank has a first aeration tube. The aerobic tank has a second aeration tube. The inlet receives a waste stream and enters the equalization/separation tank at an equalization/separation tank bottom portion and leaves at an equalization/separation tank top portion. The waste stream enters the anaerobic tank at an anaerobic tank bottom portion and leaves at an anaerobic top portion. The waste stream enters the aerobic tank at an aerobic tank bottom portion and leaves at an anaerobic top portion.

A biosolids concentrator and digester system comprises:

an inlet;
an equalization/separation tank;
an equalization/separation tank-anaerobic tank connector;
an anaerobic tank;
an anaerobic tank-aerobic tank connector;
an aerobic tank;
an aerobic tank-clarifier tank connector;
and,
a clarifier tank;
wherein the inlet receives a waste stream;
wherein the inlet is in fluid communication with the equalization/separation tank;
wherein the equalization/separation tank comprises:
an equalization/separation tank top portion;
an equalization/separation tank bottom portion;
and,
a first aeration tube;
wherein the anaerobic tank comprises:
an anaerobic tank top portion;
and,
an anaerobic tank bottom portion;
wherein the aerobic tank comprises:
an aerobic tank top portion;
an aerobic tank bottom portion;
and,
a second aeration tube;
wherein the equalization/separation tank is in fluid communication with the anaerobic tank through the equalization/separation tank-anaerobic tank connector;
wherein the waste stream enters the equalization/separation tank through the inlet at the equalization/separation tank bottom portion;
wherein the waste stream leaves the equalization/separation tank through the equalization/separation tank-anaerobic tank connector at the equalization/separation tank top portion;
wherein the anaerobic tank is in fluid communication with the aerobic tank through the anaerobic tank-aerobic tank connector;
wherein the waste stream enters the anaerobic tank through the equalization/separation tank-anaerobic tank connector at the anaerobic tank bottom portion;
wherein the waste stream leaves the anaerobic tank through the anaerobic tank-aerobic tank connector at the anaerobic top portion;
wherein the aerobic tank is in fluid communication with the clarifier tank through the aerobic tank-clarifier tank connector;
wherein the waste stream enters the aerobic tank through the anaerobic tank-aerobic tank connector at the aerobic tank bottom portion;
wherein the waste stream leaves the aerobic tank through the aerobic tank-clarifier tank connector at the anaerobic top portion.
