A system and apparatus configured to facilitate on-site treatment of wastewater from a residence is described. The system is configured to immediately treat wastewater as it is generated, on an as-needed basis, and works to remove undissolved down solids and reduce dissolved materials concentrations to a uniform level prior to transmission of the wastewater to municipal waste water treatment facilities and/or any non-drinking application. The system employs a two-stage treatment apparatus where the first stage is configured to pre-grind and decompose undissolved solids of the wastewater and the second to reduce dissolved materials concentrations. The first stage uses turbidity meters, and the second stage uses pH, BOD and conductivity to ensure a uniform output from each stage. A fast decomposer has rotating filters which operational modes ensure that the filters do not become clogged with solids in a cake form simultaneously.

Vibratory screening machines that include stacked screening deck assemblies are provided. In some embodiments, at least one of the vibratory screening machines may include an outer frame, an inner frame connected to the outer frame, and a vibratory motor assembly secured to the inner frame for vibrating the inner frame. A plurality of screen deck assemblies may be attached to the inner frame in a stacked arrangement, each configured to receive replaceable screen assemblies. The screen assemblies may be secured to respective ones of the plurality of the screen deck assemblies by tensioning the screen assemblies in a direction that a material to be screened flows across the screen assemblies. An undersized material discharge assembly may be configured to receive materials that pass through the screen assemblies, and an oversized material discharge assembly having a deflector may be configured to receive materials that pass over the screen assemblies.

An example nonlimiting embodiment of the present invention provides a flow divider that includes a slurry receiving compartment and a discharge arrangement having a plurality of discharge apertures. The slurry receiving compartment is arranged to relatively uniformly flow a portion of a slurry into each of the discharge apertures. The discharge apertures may be arranged linearly and/or horizontally such that the portions of the slurry exits each of the discharge apertures at a relatively even flow rate and feed feed boxes connected to vertically tiered screening surfaces of a screening machine.
