Dissolution and Biokinetics of PCL in Denitrification Systems
… time, and bead reuse on PCL dissolution and soluble chemical oxygen demand (SCOD) release. The dissolution behavior was represented using a modified Noyes-Whitney model, which was calibrated to capture the kinetics and predict carbon release over time. Many previous studies have overlooked …

Biological Health Assessment of an Industrial Wastewater Treatment Facility
… mixed liquor suspended solids (MLSS), removal of soluble chemical oxygen demand (sCOD), and specific oxygen uptake rates (sOUR). Graphite appeared to have no adverse effect on the microbes. The potential benefits of adding sucrose, nitrogen, and phosphorus to SBRs were evaluated. The MLSS was …

Thermal Hydrolysis of LCFAs and Influence of pH on Acid-phase Codigestion of FOG
… up to 250 °C (30-min hydrolysis). The use of chemical-thermal treatments was also investigated. Only unsaturated LCFAs, C18:1 and C18:2, were degraded when thermally hydrolyzed with hydrogen peroxide coupled with activated carbon or copper sulfate. Semi-continuous, acid-phase digesters (APDs) …

Evaluation of an Effluent Treatment Strategy to Control Nitrogen From a Recirculating Aquaculture Facility
… under different initial nitrate-nitrogen and soluble organic carbon to nitrate-nitrogen ratios. Characterization of soluble organic carbon (measured as soluble chemical oxygen demand, sCOD) indicated that volatile fatty acids (VFA) were generated during the fermentation of the waste fish …

Biomethane production from grass silage: laboratory assessment to maximise yields
… with rumen fluid addition. The concept of demand driven biogas was also examined in a two-phase digestion system (leaching with UASB). When demand for electricity is low it is recommended to disconnect the UASB from the system and recirculate rumen fluid to increase volatile fatty acid …

Evaluating the potential for improving anaerobic digestion of cellulosic waste via routine bioaugmentation and alkaline pretreatment
… Neutral detergent fiber (NDF) analysis and net soluble chemical oxygen demand (sCOD) generation suggested that routine bioaugmentation improved substrate hydrolysis by 22-25% in comparison to one-time bioaugmentation after 14 days of operation. Methane yields from routine bioaugmented conditions …

Pre-treatment and anaerobic codigestion of waste activated sludge from a petrochemical wastewater treatment plant
… of waste activated sludge produced in a petrochemical wastewater treatment plant (PWWTP) to improve its subsequent anaerobic digestion. Following pre-treatment, the study specifically focusses on digestion of the pre-treated sludge in an attached-growth down-flow anaerobic digester with …
