  • A high-performance electropositive filter

    Reverse osmosis (RO) membranes have become the industry standard for purification of any feed water source. They are used extensively for producing high-purity, low-conductivity process water. They are also used for producing ultrapure water from fresh water because RO is presumed to be the ultimate purifier. Because RO filters are readily fouled by colloidal particles and biofilms, some method ...
