The individual UF module flow ranges depend upon the source water quality and pretreatment. Consult with AMI for specific design flow rates for a specific application. Housings and Filtrate Connectors for HF UF Membranes Our hollow fiber UF membranes can be used in standard housings with the appropriate Filterate Connector Kit as listed below. Please click here to view our complete line of membrane housings. For 4” Diameter elements, a specialty vessel with a larger filtrate port is available to reduce pressure drop. These are special order items and may not be in stock. Please choose the appropriate connector kits below to adapt the hollow fiber elements to the vessel you will be using. (Two connectors are required per pressure vessel.)
