Trouble with RO

摘要

Many refineries and chemical plants have replaced or supplemented sodium zeolite softeners with reverse osmosis (RO) membrane units to remove soluble contaminants from water used as boiler makeup.Benefits of RO systems include: Improved boiler feedwater quality; Elimination of usage of large volumes of acid and caustic as required by demineralizer systems;Significant reduction of boiler blowdown flowrate;Increased water,energy and chemical efficiencies.
