Digester/Thickener

conventional aerobic digestion, operating costs can be reduced by 50 percent. By adding sludge transfer pumps, thickener underflow can be recirculated to the digester to increase the solids retention time (SRT), which will improve stabilization and increase the thickened sludge concentration. The digester and thickener

MEMBRANE THICKENING AEROBIC DIGESTION

Membrane thickening aerobic digestion processes produces a Class B stabilized sludge with reliable thickening without using polymers or decanting, allowing wastewater facilities to expand solids storage capacity in existing process tanks and minimize the footprint of newly constructed tanks.

The effect of stabilization on the utilization of

Data analysis revealed that anaerobic sludge contains higher concentrations of Cr, Hg, and Ni compared to aerobic and nonbiologically stabilized sludge. A similar observation was observed in the

GTAD™ Process

the effect of alternating anoxic/aerobic phases. Scum is collected in the gravity thickener using a scum collection system (e.g. scum beach or slotted pipe skimmer) and is also airlifted to the "inloop" Digester. Digested sludge overflows from the Aerobic Digester to the PreMix, where it is mixed with incoming raw sludge, completing the loop.

TECHNICAL MEMORANDUM CITY OF PALATKA, FLORIDA

Gravity Sludge Thickener Primary/Secondary sludge concentration is accomplished by conveyance to the Gravity Sludge Thickener, which subsequently reduces the hydraulic volume of sludge that is delivered to the Anaerobic Digester(s). The WWTP includes one (1) Gravity Sludge Thickener with a diameter of 35feet and side water depth of 12feet.

Monitoring of odors emitted from stabilized dewatered

Based on Pearson correlation coefficient, we revealed a correlation between odorous substances emitted from aged, stabilized dewatered sludge cakes. It was revealed that stabilized dewatered sludge still possessed significant amount of odorous compounds and applied measurement technique could be used for monitoring of odor concentration level

US4246099A Aerobic/anaerobic sludge digestion process

A process for digestion of sludge wherein the sludge is oxygenated in a first digestion zone at temperature of from 35° to 75° C. to partially reduce the biodegradable volatile suspended solids content of the sludge. The partially stabilized sludge is anaerobically digested in a covered second digestion zone at temperature of from 25° to 60° C. to further reduce the biodegradable volatile
