Xiga 55 ultrafiltration (UF) membrane modules are an excellent treatment method for large-scale surface water, wastewater treatment plant effluent and well water projects with suspended solids levels of up to 50 mg/L. The 8” PVC membrane elements (up to four) are placed in 9” membrane housings. Each membrane module hydraulically operates in parallel, regardless of its position in the system.
Xiga 55 provides a simple solution to produce water which meets the highest standards for turbidity and microbiology. The hollow fiber membranes on the inside effectively reject viruses and chlorine resistant organisms, such as Cryptosporidium and Giardia.
