Abstract: An orbital wastewater treatment system includes a tank assembly, at least one impeller, at least one flow-diversion mechanism, at least one actuator, optionally at least one sensor disposed in the tank assembly, and a control unit. The tank assembly has three treatment zones and pairs of passages between the first zone and the second zone and between the second zone and the third zone. The impeller disposed in the tank assembly moves mixed liquor under process about the tank assembly. Multiple flow-diversion mechanisms disposed at the passages between the zones of each pair control process conditions pursuant to a predetermined schedule and/or at least partially in accordance with input from the one or more sensors.

Abstract: A vertical motion mixer has a drive mechanism with two axes of guidance for vertical motion. A reciprocating yoke is fixedly secured to the driving shaft for the mixer, without any guide bearing for the mixer driving shaft. The mixer drive unit is of compact and simplified design with minimal moving parts, and including drive gearing with planetary gears to minimize wear during reciprocating movement.

Abstract: Silicon carbide flat sheet filtration membranes are supported on one piece manifold/end cap structures. Ends of a large number of the parallel flat plate membranes are fitted into elongated end cap slots that are part of a single molded manifold/end cap structure, such a structure being at each end of the series of membranes. In addition, a one piece external frame module can be provided to receive the gang of flat plate membranes with attached manifold/end caps. In the event of a damaged plate, the plate can be removed and replaced along with a special end cap repair section. This provides advantages over prior arrangements with individual end caps for each module or potting of the flat plates into a box or chamber.

Abstract: In a wastewater treatment process or other water treatment process, wherein ceramic membranes are employed to filter liquid not being treated in a biological process, ozone gas is injected and dissolved into the membrane influent for the purpose of preventing fouling of the membranes, while also enhancing pathogen removal. Ozone concentration as injected is at a concentration greater than 2 mg/l, preferably at least about 5 mg/l.

Abstract: A liquid level control system employs a flap gate for discharging liquid, but with a midstream headloss inducing device between the basin or tank and the flap gate. The flap gate opens when liquid level in the basin rises, and the opening of the gate is controlled by a counterweight positioned so as to decrease closing force as the gate opens farther, thus managing the outflow of liquid to efficiently return the basin to a design level. If flow from the basin is generally constant, the system will reach a point of equilibrium of gate opening and closing forces while liquid flows out from the basin.

Abstract: A wastewater filter assembly has a base, a filter module or casing, modular filter plates disposed in said filter module or casing atop the base, a header disposed on the filter module, tie rods each coupled at a lower end to the base, and tensioning elements removably connected to upper ends of the tie rods to fix the tie rods to the filter module and press the filter plates into relative rigid relationship. The tie rods are disposed in laterally open elongate channels extending along vertical edges of the filter module. The tie rods, upon a loosening or removal of the respective tensioning elements, can be shifted at least partially in a horizontal direction out of the laterally open elongate channels and laterally away from the filter module.

Abstract: A wastewater treatment system includes a biological treatment plant and an auxiliary, non-biological treatment plant. The auxiliary plant receives overflow, which can be sanitary sewer overflow, combined sewer overflow or strictly storm overflow. Treatment is by coagulation and membrane separation, removing most bacteria. Following treatment the outflow can be discharged to streams.

Abstract: In a hydraulic circuit including a ball circulation pump skid, a single pump, and a set of valves in a manifold of the ball circulation pump skid, the pump and valves are operated to move all fluid in the hydraulic circuit alternately along two paths through an operative device and a ball collection capsule in the manifold, so that none of the balls ever enter the pump. The first path enables (a) ball-containing fluid flow from the operative device to the ball collection capsule and (b) ball-free fluid flow from the ball collection capsule to the exactly one pump and back to the manifold. The second path provides for (c) ball-free fluid flow from the pump to the ball collection capsule and (d) ball-entraining flow from the ball collection capsule to the operative device.

Abstract: A submerged membrane unit has air diffusers located outside of the membrane area in plan view. The diffusers may be mounted in or below a diffuser case. The diffuser case may have walls to direct bubbles towards the membranes. The diffusers may be drop diffusers, for example as in a single drop diffuser assembly. The membrane unit may have polymeric or ceramic membranes, for example ceramic flat plate membranes. In an example, a rectangular shrouded membrane unit has a diffuser case below it that is rectangular in plan view but trapezoidal in side view, with drop diffusers located in the corners of the diffuser case. In a process of treating high strength wastewater, for example thickening or digesting waste sludge, a membrane unit optionally with ceramic plate membranes is immersed in the wastewater. The membranes are sparged with bubbles produced below but beside the membrane unit in a diffuser case.
