SDS, a water infrastructure systems specialist, has released a water recycling system that promises to boost business sector efforts to save water by offering significantly improved investment returns for commercial developers and operators.
The SDS GWOD uses a state-of-the-art ultrafiltration technology, unique to the UK, together with smart controls, to deliver a space-saving, low-energy and responsive water reuse system, for commercial buildings, hotels and leisure centres.
The SDS Greywater on Demand (GWOD) system is set to be a flagship technology of the company’s water reuse product range. It is also one of the first to be equipped with SDS’s SYMBiotICTM automated smart controls incorporating cloud-based monitoring to ensure that process performance is optimised.
The GWOD’s small footprint, together with its ability to provide, on-demand, quality recycled water whenever needed, makes it capable of improved investment payback when compared to conventional Membrane Bioreactor (MBR) greywater systems, especially for larger-scale systems.
SDS’ Water Recycling Specialist, Kevin Reed said: “In the past, MBR systems have tended to be the technology of choice. Our ultrafiltration system typically processes water at about 2m3 per hour per filter, compared to an MBR system which processes at about 4m3 per day per membrane. As a result of the faster treatment, the storage volume, and therefore the tank size, is considerably smaller than for a typical MBR system.
“Using ultrafiltration also makes the system responsive to demand at peak times. Unlike MBR, our system does not depend on having to build up a biomass of bacteria for peak operation. High quality water is available immediately on start up. This also means that the system can be shut down when not in use, for example in an office block at weekends or holidays. In this way the system saves energy, too.”
The SDS Greywater on Demand system can pay back in as little as seven years, although actual return on investment will depend on the size of the system and the local Water Company charges. SDS offers a full design and installation service to support Public Health Engineers, developers and commercial operators and ensure correct system sizing for maximum savings.
