Cartridge filter cleaning helps in reduction of plastic pollution caused by cartridge filters in the water treatment industry, which is 20 to 100 times higher in volume than that caused by RO membrane elements.
WD News: H2O Innovation Inc has performed a cleaning-in-place for cartridge filters at a water treatment facility using its Genesys-PWT membrane cleaners. This new cleaning method could prevent water treatment facilities from disposing of millions of cartridge filters each year, thereby helping them reduce their plastic waste and achieve their sustainability objectives.
Over time, the sediment collected on cartridge filters creates physical and chemical fouling, which causes their performance to drop. As a result, Reverse Osmosis (RO) plant operators need to conduct periodical cartridge filter replacement to maintain optimal membrane performance and are constrained to sending the old filters to landfill.
In some plants, cartridge filter replacement occurs several times a year or even monthly, resulting in not only cartridge costs but also in substantial losses due to the downtime required for filter replacement. Some plants may have up to 20,000 cartridge filter units, making replacement time very significant.
“Our laboratory in Madrid, Spain, which is specialised in membrane performance and filtration, has performed over 1,700 membrane autopsies. This has led us to apply the same chemical cleaning solution to cartridge filters, allowing a greener and more sustainable process,” stated Frédéric Dugré, President and Chief Executive Officer of H2O Innovation.
