D&S HO Water Treatment Division has in July successfully commissioned a large de-flouridation system at Little Sisters of St. Francis Learning and Hospital Community Centre at Kasarani in Nairobi. The plant was financed by D&S partner DOW Chemicals in conjunction with KIWASH-USAID as a CSR initiative for the institution.
The water treatment system comprises of a 15m3 /hr Ultrafiltration pretreatment process before Nanofiltration to remove the fluoride.
Nanofiltration is a recent technological advance that demineralizes water of undesirable elements without the high energy input and water rejection rate normally associated with reverse osmosis (RO) processes. Thought to be the first Nanofiltration system ever installed in Kenya, the plant was commissioned by U.S Undersecretary of Commerce Gilbert Kaplan with D&S Technical Director Eng.
