What is designed procedure for RO equipments?
Many factors affect the separation process, including: pressure, temperature, flow rate, percent of passage through membrane, amount of matter in raw liquid, and type of matter in raw liquid. All of these factors must be considered in the design of the reverse osmosis system. The basic components of the reverse osmosis system are the membranes and the pump which drives liquid through the membranes. The balance of the system componently is made up of piping and valving to route fluid through the system, monitoring apparatus, electronic control of the process, and raw fluid pretreatment. As purified water passes through the membrane it leaves the rejected contaminants behind, concentrating the solution at the membrane surface. The system must be properly designed and maintained to avoid the precipitation of these concentrated contaminants on the membrane surface. Pretreatment processes such as filtration, ion exchange, antiscalant injection, and pH adjustment are utilized to assist in pr
