The technology, which is being developed by Clear Water Revival at Cranfield University’s Water Science Institute, uses natural processes instead of chemicals to control algae and pathogens in the water.
According to Clear Water Revival director Andrew Cox, the long-term costs of natural filtration methods are up to 10 times lower than the ongoing cost of running a chlorine pool.
Fellow Clear Water Revival director David Nettleton said: “This is a perfect example of harnessing the power of [the] Internet to fund an ecological technology which has huge potential to create wealth and jobs for the UK economy, and now anyone can use the Crowdcube platform to invest in our ecological filtration technology from as little as £10.”
The funds will be used to commercialise Clear Water Revival’s natural biofilter technology and to expand into new global markets.
Eco entrepreneurs Nettleton and Cox established Clear Water Revival in 2006. The company, which is based in Bristol, has built more than 60 natural swimming pools since 2006 and expects to build another 12 in 2014.
Clear Water Revival secured a £90 000 UK government SMART grant for innovation in 2012.
