Closed Circuit Reverse Osmosis – A Better Mousetrap for the Water Purification Needs of the Paper Industry, TAPPICon22

The demand for pure water in the paper and tissue manufacturing industries can range from utility water requirements with boilers and cooling towers, process needs for use with specific equipment, as well as wastewater reuse. Reverse osmosis (RO) is recognized as a critically important technology to utilize to help meet these demands. Although the technology is very effective at producing purified water, conventional RO does however have many limitations and Pain points associated with its operation. These include low efficiency rates, high maintenance due to fouling and scaling of membranes, short membrane life, difficulty in managing variability of operating conditions, compromised product water quality, high operating costs, and the list goes on. As the demands of industrial customers have changed and focus on sustainability as well as improved reliability of operations has become more prominent, the old ways of Reverse osmosis have been in need of an overhaul. The key to solving the issues of RO ultimately have come down to a reinvention the basic filtration process starting from scratch.
