Abstract: A system and method for reclaiming and treating groundwater collected from an underground level of a structure or building site to supply non-potable water to an end use system, such as an irrigation system, a pond, an equipment washing system, a cooling system, or a heating system. Groundwater seeps into such underground levels and has to be pumped out to prevent flooding the structure. Normally, this groundwater is discharged as a waste stream but can be treated for non-potable use using an three-stage treatment system comprising an ultrafiltration system, a water softener system, and a reverse osmosis system. The water softener system may be used or bypassed depending on acceptable TDS levels in the end use system and the TDS level of the reclaimed groundwater. Use of the system and method can save millions of gallons of groundwater per year per building site from being wasted.

Abstract: A greywater treatment system includes a first modular greywater processing apparatus having a raw greywater inlet, a mechanical (MTF) filter connected to the raw greywater inlet, a first ultrafine (UF) filter connected in series downstream of the mechanical filter. The UF filter includes a UF filter inlet, a filtrate outlet, and a cross-flow outlet. The filtrate outlet is connected to a processed water outlet. A modular base supports the mechanical filter and the UF filter.
