Executive summary<\/strong>

This 1000 LPH RO OPEX calculator helps you estimate monthly cost based on real operating assumptions\u2014energy, chemicals, cartridges, CIP and membrane amortization.At the 1000 LPH scale, RO OPEX is dominated by energy<\/strong>, chemicals<\/strong> (antiscalant, dechlorination, pH control\/CIP), \u0645\u0631\u0634\u062d\u0627\u062a \u062e\u0631\u0637\u0648\u0634\u0629<\/strong>, \u062a\u0648\u0627\u062a\u0631 CIP<\/strong> \u0648 membrane amortization<\/strong>. With correct pretreatment (SDI \u2264 3<\/strong>) and realistic recovery (55\u201370%<\/strong>), many small plants run 3\u20136 months<\/strong> between CIPs and keep cost per m\u00b3 stable.
