Self-Adaptive Control And Optimization Of Ultrafiltration

UC Case No. 2016-159SUMMARYUCLA researchers in the Department of Chemical and Biomolecular engineering have developed a novel UF-RO system.BACKGROUNDUltrafiltration (UF) is the process of membrane-based removal of particles. It is used in a number of different industries such as food production, water treatment, desalination etc. In particular, in water...

2011-138 Integrated Ultrafiltration and Reverse Osmosis Process and System

SUMMARYProfessor Cohen and colleagues have developed a compact and self-adaptive integrated water ultrafiltration and reverse osmosis (UF/RO) process and system. Designed to produce up to 18,000 gallons of drinking quality water per day with no intermediate tanks between UF and RO or for UF backwash, the system can be further expanded for even larger...
