Reverse Osmosis

Treatment4Water supplies water treatment chemicals for the efficient operation of the reverse osmosis process. 

The efficient operation of the reverse osmosis process is subject to impure water passing freely across the membrane to produce pure product water. The process is vulnerable to build up of concentrated matter on the membrane surface, due to microbial fouling and insoluble scale. Effective chemical and mechanical treatments at stages throughout the reverse osmosis process will reduce the ability for these species to affect the output of the system, prolong the length of time in between off-line maintenance cleans, and extend the life of the membrane. Effective off-line cleaning is a vital function regarding the efficient operation of the membrane process.

Our SYN-RO product range below is designed to optimise the performance and longevity of the RO system.
