It is available as part of JWC Environmental's (JWCE) complete Monster Separation System fine screen unit or for installation to accept solids behind current screens.
JWCE's Smart Controller logic has three fully programmable operational stages which continually monitor the operation of the system. Each stage provides separate controls to provide proper washing of solids. The new low profile wash tank design is large enough to deal with heavy solids loading and still properly wash material via separate inlet, washing and dewatering zones. Two inspection ports allow operators to visually inspect the inside of the tank. The low height profile also allows the SWM-XE to fit into challenging installation retro-fit requirements. The SWM-XE uses a triple zone spray wash system to eliminate nearly all faecal matter and reduce foul odours. An initial spray wash zone, in the hopper, washes incoming solids as they are fed directly onto the cutters of the grinder, allowing quick processing, especially when greasy material is involved. The second zone is located between the grinder and auger. This patented use of wash water, after the grinder, washes soft organics from ground captured solids and provides homogenous, dry discharge. The third wash zone is located in the lower tank and ensures the screen and pipe remains clear.

This microfiltration module in a plate-and-frame configuration consists of flat sheet PVDF membranes which are cast with polyester, non-woven fabric as the base layer. This combination of materials gives the membrane superior physical strength and chemical stability. The Toray MEMBRAY MBR module is comprised of an element block and an aeration block. The element block contains the PVDF membrane filter elements stacked at equal intervals. Each element is connected via a polyurethane tube to a permeate water manifold. The aeration block consists of air diffusers used to supply air to the MBR module. The module can be submerged directly into an activated sludge tank for combining biological treatment and membrane separation. It eliminates the secondary sedimentation process and reduces the activated sludge tank size. The flat sheet MBR plate-and-frame configuration is inherently more resistant to fouling than the hollow fibre membrane configuration. Therefore, it results in fewer chemical cleaning requirements. The reduced module fouling from human hair and other obstructive substances allows for coarser screening as a pretreatment process.
