The Technology
Instead of being flushed down the drain the backwash water is pumped through the PwlltecEC electrode cell across which a small electric current is applied.
A reaction takes place between the plate material and the dissolved waste so that it coagulates sufficiently to be filtered out, leaving clean water. A final treatment through a UV system eliminates any bacteria and the warm water is returned to the pool. The PwlltecEC system is fully automated and can be monitored and operated remotely.

Decarbonisation
The Elentec warm water recovery system can form a major part of decarbonisation activities because of the annual savings in energy that can be demonstrated.
Two examples:
Pool 1 – 3297 m3 water recycled – 77,145 kwh energy saved – 24,580 kg CO2 savings generated
Pool 2 – 9282 m3 water recycled – 217,199 kwh energy saved – 69,243 kg CO2 savings generated
With energy costs, and the drive for sustainability, if ever there was a time for product like this, it is NOW.
Why now & why does it work?
With pressure on energy costs, as well as the drive for sustainability, if ever there was a time for product like this, it is NOW.
Energy costs, inflation, the push for sustainability are all drivers that will continue to support this market for the foreseeable future.
After extensive testing, the first system is installed and working. Data indicates that the pool will save 2000 tonnes of water per annum and energy savings (water heating) will be in the region of 44,000 kWh/year.
Savings on water, sewerage and energy mean the PwlltecEC system should pay for itself within two years.
