RO High Silica Antiscalant is a pretreatment water additive suited for reverse osmosis system. It is extremely effective and can prevent the membranes from being contaminated. This is suited for reverse osmosis applications and can do away with scaling as well as buildup of deposits. It has high permeate quality, low water and energy costs and low permeate production. RO High Silica Antiscalant is a highly efficient dispersant and antiscalant suited for the reverse osmosis membrane systems. It can work for high silica feed waters and is functional as an actual antiscalant.
