Multi Cyclone, a new Australian-designed and patented swimming pool filtration device, has been awarded the 2007 Piscina Barcelona Sustainability Award at the International Swimming Pool Exhibition, Piscina BCN, which was held in Barcelona in October.
Designed by Waterco, the Multi Cyclone has no moving parts to wear and no filter media to clean or replace.
The Multi Cyclone works on the basis of centrifugal water filtration.
Incoming water is guided by a diverter plate so that it enters multiple hydro cyclones tangentially, generating a strong centrifugal effect.
This spins the sediment out to the hydro cyclone’s wall and then spirals it down to the sediment sump, while the cleansed water spirals upwards.
The accumulation of sediment can be visibly monitored through the MultiCylcone’s clear sediment sump. The MultiCyclone is cleaned by simply opening its purge valve. Only 15 litres of water is discharged to clean the MultiCyclone of sediment.
Instigated by the Swimming Pool Exhibition and organised by the Catalan Institute of Construction Technology, ITeC, judges reviewed a total of 63 products from 50 international companies and judged the Multi Cyclone to be the best.
The Multi Cyclone is ideal as a pre-filter and will extend the life of existing filters. The Multi Cyclone works together with sand, diatomaceous earth or cartridge filters, fitting between the pump and the existing filter.
The Multi Cyclone filters out up to 80% of the incoming sediment before the existing filter even gets to see the water. The end result is that the filter requires less cleaning, saving water and time.
For a sand filter, the water savings can be up to 5000 litres a year through less frequent backwashing. Cartridge filters may only need to be cleaned once every one or two years, depending on their size.
The Multi Cyclone is under world-wide patent pending and has just been released in Australia.
