摘要： A method for wastewater treatment, in a continuous flow system, and a plant for wastewater treatment, to achieve high level reduction of biogenic nitrate compounds are provided. Subjecting a mixture of active sludge and wastewater to vacuum degassing on the mixture that has been subject to earlier nitrification, but not introduced in a recirculation-return connection, and constituting the outflow from a nitrification volume, before degassing, is subject to additional denitrification. The mixture of active sludge and wastewater, due to the additional denitrification step, may be free of carbon carried along with wastewater. An external source of readily available carbon is introduced, and further deepened nitrates removal is performed. After wastewater is degassed, treatment continues within a gaseous nitrogen undersaturated aqueous zone of a secondary sedimentation tank.

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 membrane bioreactor (MBR) has membranes comprising a supporting structure. A supply unit doses a sorbent such as powdered activated carbon (PAC) into the MBR. The PAC is maintained at a concentration in the mixed liquor of 200 mg/L or more. Mixed liquor with the sorbent particles recirculates within the MBR at a flow rate of at least twice the feed flow rate. Air bubbles are provided to scour the membranes including during at least part of a permeation step. The sorbent particles are present in the mixed liquor and contact the membranes. Bioaugmentation products may be immobilized on PAC or other carriers and then added to an MBR or other bioreactors.

摘要： Compositions and methods for in situ ground water remediation. The compositions comprise a colloidal biomatrix comprised of sorbent particles, such as zeolites, organoclays and activated carbon, dispersed in aqueous solution that are injectable into the permeable zones of an aquifer to be treated. Once deposited into the permeable zones of the aquifer, the groundwater concentrations of contaminants in those zones are depleted, thus increasing the rate of diffusion of contaminants of the less permeable zones. The compositions and methods of the present invention can be used to treat any organic contaminants and provide rapid remediation of contaminated ground water by adsorption and biodegradation of such contaminants.
