A method for manufacturing wastewater filtration plates uses a flowable composition including pre-ceramic raw material. The flowable composition is extruded to form a thin plate preform. Carbon-containing material is included in the flowable composition and/or added to the surface of the thin plate perform during or after extrusion thereof. The carbon-containing material is preformed carbon filaments or carbon-fiber precursor material. The thin plate preform is subjected to elevated temperatures to convert the pre-ceramic raw material into porous ceramic with carbon filaments embedded therein or disposed on the surface of the finished ceramic plate.

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.

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.
