Reverse Osmosis – Model KR KRFU 6000
KR and KR/FU – 4000–10000 l/h RO Systems with special concentrate stage. Stand-type unit for desalination of softened drinking water according to German drinking water regulations (free chlorine not detectable), operating on the principle of reverse osmosis, with very high permeate recovery up to 90 % due to additional concentrate stage and high salt rejection up to 98.5 %.
Stainless steel main frame housing the instruments and controls. Special inlet filter with 5 μm-filter cartridge, high pressure pump low noise (incl. frequency converter for KR/FU systems), multi-stage centrifugal type, specially combined spirally wound modules with PA/PS composite membranes in GRP vessels with inline.
