摘要： A screen decanter for decanting liquid from a reservoir, comprising at least one rack comprising screens and baffles forming the sides of a cavity; a frame attached to the screens and baffles and providing a barrier so that liquid cannot pass from outside into the cavity without passing through the screens; a patterned perforated drain pipe inside the cavity and leading to an opening through which liquids may drain out from the cavity. The pattern of the openings counteracts the hydrostatic head within the rack such that flow through the screens is uniform at all depths of immersion in the liquid reservoir. Preferably, the screens have a porosity of about 50 micrometers.

摘要： The present disclosure relates to a biofilter for wastewater digestion, in which a high degree of contaminant removal is obtained with a single device. In order for these levels to be achieved, the following are essential: the shape of the biofilter, the supply/discharge ratio of the biofilter, the position and height of each of the components and, finally, the combination of two packed zones, namely: a random zone, and a zone arranged in the form of ringed or corrugated tube bundles.

摘要： This invention describes the equipment and a method to recover starch from a dilute starch stream produced by manufacturing facilities which process the starch-containing materials, such as potato and corn. The process comprises feeding a dilute aqueous slurry of less than about 5% by weight starch to a classifier to concentrate the slurry by a factor of at least 5 and produce a concentrated slurry, wherein the classifier has at least one overflow exit and at least one underflow exit; drawing off the overflow and underflow from the classifier; feeding the concentrated slurry from the underflow exit of the classifier into a settling tank having at least one underflow exit and at least one overflow exit to produce an underflow layer of starch with a concentration of at least 40% starch proximate to the underflow exit and an aqueous overflow with a concentration of less than about 5% by weight starch proximate to the overflow exit; drawing off the overflow from the tank; and opening a orifice at the underflow exit of the tank to allow the distal most fraction of the underflow to exit the tank.

摘要： Polymer flocculants are described comprising blends of high molecular weight polyethylene oxide and high molecular polyacrylamides. When introduced in desired amounts and with desired molecular weight ranges, excellent flocculation function is found that can be used to reduce polymer consumption to obtain a desired purity of clarified waste water. It has been found that the desirable polymer blends can be effectively added upstream from locations in which polyethylene oxide would generally be added so that the polymer blend can effectively mix with the slime flow to reduce or eliminate the need for excess polymer use to compensate for less effective mixing with the slime flow. Suitable waste treatment systems are described to provide for the delivery of the flocculants in the waste treatment process.
