Energy efficient low fouling high recovery reverse osmosis system for brackish water desalination

摘要

A novel multi-stage reverse osmosis system is proposed to enable the following advantages: - a) reducing the pressure loss while achieving optimal cross flow velocitySo reduce energy consumption by 4 toIncrease the flux balance between stagesAs a result, the first stage of fouling is reduced andDividing scale formation conditionsAs a result, the final stage scaling is reduced.Reduce the scalability of the concentric valve andReduce downtime for CIP by actively scaling scaling or fouling through several inventive methodsEase and effectiveness of CIP that reduced the number of valvesWhile maintaining the remaining system in production modeMaintain system operation by separating the final stage for maintenance.All the above improvements are achieved by process flow and operational characteristics defined in the specification and claims.
