Holland Water has developed the Bifipro® system, a patented and certified solution addressing the problem of pervasive biofilm in drinking water and process water, resulting in effectively removing all harmful bacteria including Legionella. The Bifipro® is based on the principle of copper silver ionisation (CSI) which is particularly suitable for buildings with complex water supply networks and many taps, such as hotels, hospitals, public & private care institutions and recreational parks & camping sites, as well as for process water in open wet cooling towers. The new Silco® sensor technology will be key in securing sustainable chemical free and cost effective process water treatment solutions.
