This meant converting four existing tanks, which included a blending tank, two secondary digesters, and a side-stream holding tank. ...
Further, due to the lower oxygen requirements of In-Pipe bacteria, the plant is saving $60,000 a year in digester aeration energy by introducing IPT's blend of facultative heterotrophic spore forming bacteria. ...
This study investigated dewaterability (using capillary suction time, CST) of combined alum residuals (Al-WTR) and anaerobically digested biosolids at various blending ratios (BR), defined as the mass ratio of WTR to biosolids on a dry solids basis. ...
This project will provide a major upgrade to the WWTP power supply by the installation of onsite electricity generation fuelled with the digester gas produced during the treatment plant process. The reduction of greenhouse gas emissions and support for renewable energy projects are aligned with the State’s strategic plan. ...
Capturing Biogas The cornerstone of Santa Cruz WWTF’s renewable energy program is producing abundant, healthy amounts of biogas each day in its digesters. Acting like a large stomach, the solids from the wastewater treatment process are “digested” in four large, domed digesters heated to 98°F for optimal ...
The objective of the present work was to evaluate the effect of hydraulic retention time (HRT) on hydrolysis and acidogenesis for the pretreatment processes: acid phase digestion (APD) and autothermal thermophilic aerobic digestion (ATAD) using blended municipal sludge. The effect of the different pretreatment steps on mesophilic anaerobic ...
Co-digestion is the process in which wastes from various sources are treated together. Therefore, more organic carbon is added to make efficient use of existing digesters. The objectives of this study were to compare potential co-digestates, determine synergistic and antagonistic co-digestion outcomes and estimate economic benefits for preliminary screening. Over 80 wastes were identified from 54 ...
The microbial processes involved in two-phase anaerobic digestion were investigated by operating a laboratory-scale acid-phase (AP) reactor and analyzing two full-scale, two-phase anaerobic digesters operated under mesophilic (35 °C) conditions. The digesters received a blend of primary sludge and waste activated sludge (WAS). ...
The CAMBITM process utilizes high temperature and pressure to hydrolyse and disrupt sludge producing a pasteurized feed to downstream digesters that is more homogeneous and more amenable to high rate mesophilic anaerobic digestion. ...
When methane-forming bacteria breaks down the acids in the digester, large amounts of anaerobic digester gas made up of 60% methane and 40% CO2 are produced. ...
