摘要： A membrane bioreactor (MB R) (10) uses a process and apparatus for dosing flux enhancing chemicals (FEC) to respond to temporary periods of operation that cause, or are likely to cause, membrane fouling. An FEC dosing device (32) is provided in communication with a channel (20) separating a process tank (12) and the membrane filtration system (14) of an MBR. A mixer (36) in the channel (20) rapidly mixes dosed FEC with mixed liquor (18) flowing into the membrane tank. The dosing device (32) is connected to sensors (40, 42) sensing conditions in the channel or the membrane filtration system (14) or both. FEC is added to the mixed liquor (18) flowing into the membrane filtration system (14) considering conditions in the mixed liquor (18) flowing to the membrane unit or membrane operating parameters or both. The FEC dosage may be in the range of 0.05 to 10 mg/g MLSS. The process may include steps of initiating dosing, adjusting the dosing concentration, and terminating dosing.

摘要： A method of biogas production enhancement for an anaerobic digestion process is provided. The method of biogas production enhancement uses a cationic polymer to improve the efficiency of converting organic waste into biogas, such as methane containing gas. The cationic polymers typically used are a copolymer of acrylamide / dimethylaminoethyl acrylate methyl chloride. Biochemical methane potential (BMP) assay was carried out with varying amounts of cationic polymer. The results indicated much earlier and higher biogas production rates compared to the control and increasing COD removal efficiency. Further, the low concentration of cationic polymer additive can condition the charges on the surface of the anaerobic microbes and enhance synergy of the microbe community resulting in better kinetics of hydrolysis, acidogenesis and methanogenesis. Further, the low concentration of the cationic polymer can enhance the tolerance of the microbes to the toxicity of the wastewater by conditioning the microbial community.

摘要： A membrane filtration process includes pretreating an influent solution to remove suspended solids, to produce a pretreated solution. pH of the pretreated solution is adjusted to at least 8.3 or lower by injecting CO 2 into the pretreated solution, to produce a conditioned solution. Injecting CO 2 also serves to supplement bicarbonate in the conditioned solution. The conditioned solution is flowed through a membrane filtration unit, to produce a permeate solution and a retentate solution. The membrane filtration unit comprises reverse osmosis membranes or nanofiltration membranes, or both. The retentate solution is then treated to cause precipitation, to produce a supernatant solution and a reject solution. At least a portion of the supernatant solution is recirculated by combining it with the influent solution prior to the step of pretreating.
