摘要： A process for producing PHA comprises obtaining biomass produced in the course of biologically treating a first wastewater source containing RBCOD. The biomass is to be exploited with a second wastewater source having a different RBCOD content from the first wastewater source in order to accumulate and thereby produce PHA. Before subjecting the biomass to a PHA accumulation process, the biomass PHA accumulation potential is enhanced via an acclimation process with the second wastewater source. During acclimation, the biomass is subjected to repeated feast-famine periods. During each feast period, the biomass is exposed to a fraction of the second wastewater source. The RBCOD uptake and/or biomass respiration rate is directly or indirectly measured during each feast period. The famine period is maintained for a period of time that is at least two times greater than the length of time of the proceeding feast period. After at least two feast-famine acclimation periods or after one or more measured parameters reveal an increased RBCOD relative uptake or respiration rate of the biomass during a subsequent feast period, the biomass is subjected to a PHA accumulation process using the second wastewater source.

摘要： A method of biologically treating wastewater and, at the same time, incorporating processes that aim to increase the PHA accumulation potential of biomass used in the treatment of the wastewater. The method includes biologically treating the wastewater and enhancing PHA accumulation potential of the biomass by subjecting the biomass to a primary feast-famine process where the biomass is subjected to repeated cycles of feast and primary famine conditions. From time-to-time, the method entails deviating from the primary feast- famine process to a secondary famine process. The secondary famine process comprises subjecting the biomass to secondary famine conditions for a period of time that is substantially greater than the average time period of the primary famine conditions.

摘要： This disclosure relates to methods for producing a PHA-rich-biomass from open mixed cultures. Mixed liquor containing biomass is directed into a fed-batch reactor. The reactor includes at least one biomass stimulating zone and at least one biomass maintenance zone. A feed containing RBCOD, bioavailable N, and bioavailable P is directed into the fed-batch reactor. The respiration rate of at least a portion of the biomass is intermittently and repeatedly stimulated in the stimulating zone by directing the feed into the fed-batch reactor and exposing the biomass to a relatively high concentration of RBCOD. The biomass is then transferred to the maintenance zone, where the biomass is exposed to a relatively low concentration of RBCOD. Thereafter, the biomass is circulated back and forth between the stimulating zone and the maintenance zone. Throughout the methods, the concentration of N and/or P relative to the RBCOD in the feed is controlled by controlling the ratio of N to RBCOD and/or the ration of P to RBCOD in the feed.

摘要： A method of biologically treating wastewater and removing contaminants from the wastewater is disclosed. In the course of treating the wastewater, biomass is produced. In addition to removing contaminants from the wastewater, the process or method of the present invention entails enhancing the PHA accumulation potential of the biomass. Disclosed are a number of processes that are employed in a biological wastewater treatment system for enhancing PHA accumulation potential. For example, enhanced PHA accumulation potential is realized by exposing the biomass to feast and famine conditions and, after exposing the biomass to famine conditions, stimulating the biomass into a period of feast by exposing the biomass to feast conditions for a selected period of time by applying an average peak stimulating RBCOD feeding rate of greater than 5 mg-COD\L\MIN in combination with an average peak specific RBCOD feeding rate greater than 0.5 mg-COD\g-VSS\MIN. In another example, the PHA accumulation potential of the biomass is enhanced by subjecting the biomass to feast conditions that cause the biomass to reach a peak respiration rate that is at least 40% of the extant maximum respiration rate of the biomass. Other processes are discussed that can contribute to enhancing PHA accumulation potential of biomass.
