Greywater recycling
Greywater recycling is ideally suited to hotels, leisure centres, large office and residential blocks as it recycles water used in baths and showers to flush the toilets. Water consumption can be reduced by as much as 20%. For larger sites, it would also be possible to provide water for irrigation or laundry facilities.
Waterscan launch new and improved GW2000.
The added benefits of the new GW2000 are:
- Low energy usage (2kwh per m3) - about 24 pence per m3
- Combined rainwater harvesting and greywater management in a single system
- Integrated remote control - everything in one
- Improved ROI - as low as 2.5 years in some cases
- Volume of water re-used can be recorded on Waterline, Waterscan's unique online water management and reporting package, and monitored easily
Ultra membrane filtration
The core element in the GW2000 is the patented ultra-filtration membrane, submerged directly into the greywater tank.
The real benefit over rival systems is the very low energy required to operate the ultra filter membrane. Water is drawn across the membrane using energy efficient vacuum pumps and the result is that the system can produce 1m³ of water with only 1.5 Kw/h.
Due to the small pore size of the membrane, solid soils, bacteria and viruses are held back by the filter. The quality of the recycled grey water meets the limit values of the EU guideline for bathing water
No chemicals, self cleaning
Optimised aeration of the filter plates by periodically rising air bubbles produces a continuous cleaning effect on the filtration plates. This simultaneously ensures oxygen content in the membrane and helps to keep the filters clean. This efficient method of self-cleaning reduces the need for chemical cleaning to an absolute minimum – once a year at most.
Secure construction, low maintance
Secure operation of the GW2000 is assured by laser-welding technique developed especially for the production of filters. The backwash process is performed with clean water and means a minimum requirement for maintenance in everyday operation. The service life of the membrane can be as much as 10 years.
Enhanced Capital Allowances (ECAs)
The government's ECA programme enables UK businesses to claim 100% first year capital allowances on investments in environmental technologies such as Waterscan's approved greywater recycling equipment named on the Water Technology List. Businesses are now able to write off the whole cost of their investment against their taxable profits for the period during which they make the investment.
