The feasibility and microbial community dynamics of using down flow hanging sponges (DHS) reactor in treating high strength soft drink wastewater
… hanging sponge (DHS) reactor to treat high organic strength soft drink wastewater was investigated by operation over 700 days. At the same time, the microbial compositions were characterized and related to reactor performance. Synthetic wastewater at a concentration of 3000 mg/L chemical …

Effects of nickel on activated sludge performance at varying COD:TKN ratios
… a range of mean cell residence times, and COD removal efficiency, biokinetic coefficients, extent of nitrification, and nickel removal evaluated at each. Data from two earlier studies, in which 0.5 and 1 mg/l nickel doses were applied to similar units, were included for comparison. Organic …

Evaluation of activated carbon processes for removing trihalomethane precursors from a surface water impoundment
… GAC and BAC processes obtained the same level of organic removal; however, BAC would provide longer bed life and require less carbon than the GAC process. PAC treatment of alum coagulated water provided significantly higher TOC and THMFP removals than alum coagulation alone. The use of a …

The effects of nickel on organic removal and nitrification in the completely mixed activated sludge process
… parameter to assess the influence of nickel on organic removal efficiency, on the degree of nitrification, and on the maximum yield and the microbial maintenance energy coefficients, Y<sub>max</sub> and k<sub>d</sub>. The results obtained in this study indicated that the soluble COD removal …

Operational parameters of the filamentous microbial process
… and the carbon to phosphorus ratio which limits organic removal efficiency. Findings of this study indicate that the sludges produced by the FAS process have settling characteristics and settleability remarkably similar to the solids of conventional activated sludge. While being tested, the …

Improving integrated systems for algal biofuels and wastewater treatment
… the beneficial reuse of wastewater nutrients and organics to produce bio-crude oil. Centered around this novel system, we investigated several important aspects that can improve performance of the integrated system and resolve several of the key limitations of current algal biofuel production …
