Abrégé

A method for providing an optimized organic load to a downstream wastewater treatment process includes the steps of: providing a primary wastewater treatment plant including an organic harvester (OH) with an OH effluent output stream with temporal variation in organic content, a sludge filtrate outflow from the primary wastewater treatment plant, a valve controlled by a controller, and a sensor communicatively coupled to the controller, the sensor disposed downstream of a combined outflow line to measure an organic content of a combined outflow to the downstream wastewater treatment process; sensing the organic content of the combined outflow to the downstream wastewater treatment process; adjusting the valve controlled by the controller to maintain about a setpoint organic content concentration of the combined outflow to the downstream wastewater treatment process by supplementing the OH effluent output stream with organically rich matter from the sludge filtrate outflow.

Abrégé

A screen decanter for screening solids from waste water in a waste water treatment system comprising a drain manifold and a plurality of cylindrical cartridges mounted to the drain manifold, each of the cylindrical cartridges having an outer screen defining a cavity. Each of the cartridges includes a drain standpipe disposed within the cavity in communication with the drain manifold. Each drain standpipe includes a plurality of patterned openings arranged in at least one row along the length and partial circumference thereof and preferably comprises three rows of patterned openings, each row being disposed at a 120° rotational angle from the adjacent row of patterned openings. Each drain standpipe is disposed at a 30° rotational angle from its neighbor drain standpipe such that no row of patterned openings in any of said drain standpipes faces directly at any other row of patterned openings in any other drain standpipe.

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.

A system comprising method and apparatus for separating biologically-digestible materials from an influent sewage stream. The system may comprise a primary clarification tank to capture sixty percent or more of the total solids from an influent stream; a sludge classifying press (SCP) to isolate and concentrate biologically digestible materials from sludge formed in the primary clarification tank, releasing valuable organics, such as are found in corn kernels, by fracturing the protective casings; a grit capture mechanism in a chamber within the primary clarification tank and isolated from the bulk of the sludge containing biologically-degradable materials; a grit trap to remove grit from the sludge prior to classifying the sludge with the SCP; apparatus for adding thickener to the sludge after classification and prior to digestion; and automation of one or more elements of the process for separating and digesting the biologically digestible materials in an influent stream.

The present invention relates to a vertically adjustable screened decanter system to replace prior art stationary or pivoting effluent weirs in water clarifiers and settling basins. The screened decanter has no physical weir and relies instead on maintaining a desired flow rate by controllably varying the depth of immersion of a screened box. The decanter is periodically raised into a hood that provides spray cleaning and disinfection of the screened box. The system is capable of removing up to 85% of the BOD in a wastewater stream.

A driven decanter assembly for a wastewater primary treatment system, comprising a longitudinal decanter disposable in the wastewater and having a longitudinal trough and a horizontal entrance weir, a polygonal or arcuate screen attached to the decanter and having at least two screen surfaces disposable below the surface of the wastewater outside of the trough, and a floating baffle pivotably mounted to the decanter and disposable in the wastewater outside of the screen. The driven decanter assembly can directly replace a prior art driven decanter in any waste water primary treatment system.

Abrégé

An influent feed system for directing the influent liquid via hydraulic energy to scour the surface of primary treatment tank walls and base to move the scoured solids to a sludge trough. Scouring action takes place during periods of low liquid levels in the tank. The system comprises two identical, adjacent tanks sharing a common distribution box. Either or both of the tanks are in use at any given time. The tank in use will be empty occasionally each day. Influent feed troughs disposed transversely in each tank directs solids towards a sludge hopper in the tank bottom. The IFTs extend over the width of the tank to provide scouring of the entire end wall and floor surface. Each IFT has a sump with a valved discharge piped directly to the sludge trough, and the floor of each IFT is sloped towards the sump to facilitates draining of solids.
