SDS supplies fully automated Grey Water On Demand Recycling Systems to deliver a consistent supply of treated grey water to meet a site’s required daily volume.
Water that has been used for showering or bathing is captured and collected and, after specialised filtration, is fed back into the property for use in non-potable purposes such as flushing toilets, irrigation and laundry. Treatment is such that the filtration provides a fixed barrier to waterborne viruses and pathogens meeting required quality standards.
SDS provides the choice of two Grey Water Recycling systems which have been optimised to meet the requirements of either higher, or lower, demand volumes of water. Both systems operate on a fast treatment principle to meet demand quickly and reduce the need for large storage tanks.
Our larger scale (‘LS’) system is normally specified where demand volume exceeds around 8,000 to 10,000 litres per day, for example in an establishment such as a large hotel, student accommodation or large residential blocks, due to the nature of their water use supply versus demand equilibrium. The system uses a disc filter and hollow fibre ultrafiltration membrane, together with oxidant and sodium hypochlorite dosing incorporating an automatic backwash process, to ensure the highest level of water quality.
Our smaller scale (‘SS’) system has been developed for use where demand is sufficiently low to render the larger system financially unviable. Installation space is typically at a premium and often involves retro-fitment to existing buildings. This system uses a cartridge filter, nanofiltration cylinders and a solid block calcium hypochlorite dosing unit, together with a booster pump, all of which are built into the single control unit to save on precious space. As with the larger scale system, the quality of treated water is comparable to drinking water.
