Modeling, Instrumentation, Automation, and Optimization of Water Resource Recovery Facilities.

A review of the literature published in 2015 on topics relating to water resource recovery facilities (WRRF) in the areas of modeling, automation, measurement and sensors and optimization of wastewater treatment (or water resource reclamation) is presented.

Modeling, Instrumentation, Automation, and Optimization of Water Resource Recovery Facilities.

A review of the literature published in 2014 on topics relating to water resource recovery facilities (WRRF) in the areas of modeling, instrumentation, automation and optimization of wastewater treatment is presented. Note that WEF has adopted 'WRRF' replacing such previous terms as publicly owned treatment works, wastewater treatment plant (WWTP), and other terms and officially instituted this change in its publications beginning in 2012. It is anticipated the replaced terms will remain in use by other publications and authors for some time.

Mesophilic and thermophilic anaerobic digestion of municipal sludge and fat, oil, and grease.

The anaerobic biodegradability of municipal primary sludge, thickened waste activated sludge (TWAS), and fat, oil, and grease (FOG) was assessed using semi-continuous-feed, laboratory-scale anaerobic digesters and compared with the ultimate degradability obtained from 120-day batch digestion at 35 degrees C. In run 1, combined primary sludge and TWAS (40/60%, volatile solids [VS] basis) were fed to digesters operated at mesophilic (35 degrees C) and thermophilic (52 degrees C) temperatures at loading rates of 0.99 and 1.

Methane recovery from the anaerobic codigestion of municipal sludge and FOG.

The anaerobic biodegradability of a mix of municipal primary sludge (PS), thickened waste activated sludge (TWAS) and fat, oil, and grease (FOG) was assessed using semi-continuous feed, laboratory-scale anaerobic digesters operated at mesophilic (35 degrees C) and thermophilic (52 degrees C) temperature. Addition of a large FOG fraction (48% of the total VS load) to a PS+TWAS mix, resulted in 2.95 times larger methane yield, 152 vs.

The anaerobic biodegradability of municipal sludge and fat, oil, and grease at mesophilic conditions.

The anaerobic biodegradability of municipal primary and secondary sludge with increasing levels of partially dewatered fat, oil, and grease (FOG) was assessed using a mixed methanogenic culture at 35 "C. Under batch conditions with an acclimated and enriched microbial population, the sludge loading was 3 kg volatile solids/m3 and the highest FOG loading tested was 1.5 kg volatile solids/m3, resulting in a methane yield of 245 mL methane/g sludge volatile solids added at 35 degrees C and 1010 mL methane/g FOG volatile solids added at 35 degrees C.
