Surface treatment chemical RO systems

liquidfor the pharmaceutical industry

RO systems create salt concentrated water streams that could produce scale or fouling. Veolia's RO membrane antiscalants are pretreatment programs designed to eliminate scale and reduce fouling in membranes systems, regardless of the feedwater source. While treatment with an ordinary antiscalants does provide some improvement, the use of Veolia's patented chemistry maximizes efficacy against a broad range of scale-forming substances and keeps fouling material in suspension. The Hypersperse pretreatment program is designed to significantly reduce scale formation and fouling in membrane systems. The antiscalants are suitable and effectively used in a range of feedwater sources, including brackish, waste and seawater. The use of Veolia’s chemistries improves efficacy against a broad range of scale-forming substances and keeps fouling material in suspension. Common foulants and scalants include calcium carbonate, calcium sulfate, barium sulfate, strontium sulfate, calcium fluoride, iron, colloidal material, silica and other organic contaminants. Effectively control scales including silica, calcium carbonate, calcium sulfate, barium sulfate, and strontium sulfate Compatible with the leading reverse osmosis (RO) and nanofiltration (NF) membranes Maintain cleaner membrane surfaces by dispersing particulate foulants RO systems can be run at higher recovery rates, which translates to lower operating costs Products available with multiple global regulatory approvals Non-Phosphorus products available Effective over a wide pH range
