Dayliff MRO Reverse Osmosis Membranes are the key components in reverse osmosis water treatment plants used for removal of dissolved salts in low turbidity waters. They are of ultra low-pressure design that provides high energy efficiency giving reduced operating costs together with high salt rejection performance and a high quality specification for operating durability and long life. Two basic specifications are available for brackish and high salt level feed waters in both 4” and 8” sizes to accommodate the majority of RO applications.
MRO Membranes output is split between treated Permeate flow and high TDS Reject flow. Recovery rates (% Permeate to feed flow) depends on water quality and site operating conditions though is typically between 50-70% for brackish water and 20-50% for Sea Water. Membranes periodically require flushing and anti-scalant dosing.
