摘要： A method of biologically treating wastewater with an integrated fixed film activated sludge process. The integrated fixed film activated sludge process includes biomass suspended in mixed liquor and biomass disposed on carriers. Under certain conditions the dissolved oxygen concentration in a reactor that includes the mixed liquor, biomass suspended in the mixed liquor, and the biomass on the carriers, biological treatment is performed primarily by the biomass in the mixed liquor. This is achieved by controlling or maintaining the dissolved oxygen concentration in the reactor at a relatively low concentration. When the biomass suspended in the mixed liquor is unable to adequately biologically treat the mixed liquor, the dissolved oxygen concentration in the reactor is controlled or maintained at a relatively high concentration. This enables biomass on the carriers to contribute more to the biological treatment of the mixed liquor than when the dissolved oxygen concentration was maintained relatively low.

摘要： A method and system is provided for treating wastewater. In one process, wastewater is directed into a treatment tank and biologically treated. The biologically treated wastewater is directed as mixed liquor from the treatment tank to a bottom portion of a downstream filtration tank having at least one submerged membrane module that extends across substantially the entire cross sectional area of the filtration tank mixed liquor is directed from the bottom of the filtration tank upwardly into the membrane module such that substantially all of the mixed liquor received in the bottom of the filtration tank flows through the membrane module. As the mixed liquor flows vertically through the membrane module, the method includes inducing at least some of the mixed liquor through walls of one or more membrane filters that form a part of the membrane module, producing a permeate stream. The remaining mixed liquor passing through and from the membrane module is referred to as a non-permeate stream and the non-permeate stream, or at least a substantial portion thereof, is recirculated to the treatment tank. The filtration tank is sized relative to the membrane module and the process is carried out such that there is no substantial recycle of mixed liquor in the filtration tank itself. Although mixed liquor may be recirculated from the filtration tank back to the treatment tank and then back to the filtration tank and so forth and so on, once the mixed liquor in the filtration tank makes one pass through the membrane module the mixed liquor is recycled back to the treatment tank and generally not permitted to be recycled back through the membrane module without first returning to the treatment tank.

摘要： A method for treating water in a ballasted flocculation system comprises directing water into a ballasted flocculation zone and adding ballast and a flocculation reagent to the water to form a water-floc mixture. The water-floc mixture is directed into a settling zone to form treated water and sludge containing ballast. The ballast is then directed to a recirculation line where the ballast is recirculated to the ballasted flocculation zone. The method further includes determining the ballast concentration and comparing the ballast concentration with a predetermined threshold value. The rate at which ballast is recirculated to the ballasted flocculation zone is adjusted based on the determined ballast concentration and the predetermined threshold value. A ballasted flocculation system for treating water comprises a ballasted flocculation zone, a water inlet for directing water into the ballasted flocculation zone, and a flocculation reagent inlet for directing flocculation reagent into the ballasted flocculation zone. The system includes a settling zone for separating treated water from sludge containing ballast and a recirculation line for recirculating ballast from the settling zone to the ballasted flocculation zone. A first ballast inlet is operatively connected to the recirculation line for directing ballast into the ballasted flocculation zone. Finally, the system includes a sensor for measuring a parameter of ballast in the system.

摘要： A water treating system is provided with a membrane chamber having one or more membranes disposed therein for filtering water. To periodically clean the membranes, there is provided a series of cleaning fluid inlets that permit a cleaning fluid, such as a gas, to be injected through the inlets into the membrane chamber which results in the cleaning fluid cleaning the membranes therein. The cleaning fluid inlets are normally closed and are adapted to open in response to the pressure of the cleaning fluid reaching a certain pressure level.

摘要： A method of treating water including mixing the water with an inorganic powder reagent for reducing the content of organic matter. The water, after being mixed with the inorganic powder reagent, is subjected to a membrane separation step that produces blow off products that are then separated into two fractions: a first fraction containing a majority portion of the powder reagent in a first stream of water, and a second fraction containing a majority portion of inorganic matter not absorbed on the inorganic powder reagent rejected by the membrane separation step in a second stream of water.

摘要： A method is provided for thickening sludge produced through a ballasted flocculation process. The sludge and granular material from the ballasted flocculation process are directed to a sludge separator where the sludge is separated from the granular material. Thereafter the separated sludge is sent to a degassing area and the sludge is degassed. A flocculating agent is mixed or injected into the sludge. The sludge is directed to a sludge thickener with a load at a sill calculated on the surface of the thickener greater than 200 kgMIS/m2/day. This process produces a thickened sludge having a concentration greater than 10 gm/l.
