Anoxic mixed liquor flows (28, 20) both back to the anaerobic zone and to the aerobic zone.

The pump intakes on the bottom of the mix liquor compartment allow the pump to remove sludge build-up.

During normal operation the height of separator (D) is so fixed that the volume contained in the aeration vessel is three litres of mixed liquor.

The separation subsystem is constructed and arranged to maintain adsorbent material in the biological reactor with a mixed liquor.

A mixer (36) in the channel (20) rapidly mixes dosed FEC with mixed liquor (18) flowing into the membrane tank.

The mixed liquor stream is directed to a ballasted flocculation system where suspended solids is removed from the wastewater.

By activating the reaction of surface electrons, the mixed liquor is converted into a structure having a certain degree of magnetization.

However, in the MBR process, high concentration of mixed liquor suspended solids (MLSS) causes membrane fouling.

The first settling compartment between the trash tank and the mix liquor compartment is non-existent in conventional aerobic units.

The mixed liquor stream from the aerobic reactor is separated into sludge that can be used as fertilizer and supernatant that has been reduced in nitrogen and phorphorus.

The integrated fixed film activated sludge process includes biomass suspended in mixed liquor and biomass disposed on carriers.

Feeding mixed liquor, air and or influent to the bottom of filter assemblies via submerged conduit improves process efficiency.

A denitrification apparatus and method for use in a wastewater treatment system having a mixed liquor source is disclosed.

The suspension system is positioned in the biological reactor and is constructed and arranged to maintain adsorbent material in suspension with mixed liquor.

The aerobic zone contains suspended microorganisms of heterotrophic and autotrophic groups that grow inside the circulating liquid, known as mixed liquor.
