Ultrazur™ ZW1000 SYSTEM FEATURES

• A system made up of cassettes in series immersed in a concrete gravity-feed tank

• 4 cassettes models available all using the same-sized modules

• 2 different module densities offering either 46.5 m² or 55.7 m² filtering surface area

• Selection of module type depends on water quality at the ultrafiltration tank inlet
