“New World supplies chemicals for RO treatment (antiscalant and chemical
cleaning program) and all the needed consumables of RO unit.”
Reverse osmosis with effective pre-treatment, maintenance and appropriate RO antiscalant, membranes can give several years of useful life before they need to be replaced.
Antiscalant chemicals are used to prevent the scaling & fouling of the RO membranes. Scale may consist of mineral fouling such as calcium sulfate, calcium carbonate, barium sulfate, silica, calcium fluoride, and strontium sulfate. The Antiscalant dosing should be done before reaching the RO membranes to break up sulfate precipitates, calcium carbonate, and other mineral fouling.
Antiscalant chemical is used to process very poor quality feed water at very high rates of recovery. When used properly, Antiscalant extends the time between membrane cleanings from a few weeks to years in some cases. Without Antiscalant, membrane systems would not be as successful serving the water treatment industry.
Eventually the day comes when your RO system will require cleaning. Cleaning is recommended when your RO shows evidence of fouling, just prior to a long term shutdown, or as a matter of scheduled routine maintenance. Fouling characteristics that signal you need to clean are a 10-15% decrease in normalized permeate flow, a 10-15% decrease in normalized permeate quality, or a 10-15% increase in normalized pressure drop as measured between the feed and concentrate headers.
