Complete Water Calculators puts every Complete Water Solutions water treatment calculator in one place, so operators, engineers, plant managers and service techs can run the numbers in the field without hunting through a website. Find the right tool fast • Browse 39 calculators across 7 categories, or search by keyword (for example "LSI", "softener", "recovery" or "cost"). • Each calculator card shows what it does and which inputs you will need before you open it. • Star the tools you use most and find them again in one tap on the Favorites tab. Favorites are saved on your device. What's inside • Conversions: TDS to conductivity; GPM to m³/hr and PSI to bar. • Sizing, Volume & Hydraulics: tank volume (gallons per foot, plus CIP, storage and chemical tanks), pipe volume and pipe flow velocity. • Softeners & DI: softener capacity, softener sizing and DI resin life. • Reverse Osmosis: RO rejection and recovery, RO system sizing, recovery-increase savings and an RO system twin simulator for "what-if" changes. • RO Troubleshooting & Cleaning: RO health check, RO data analyzer, RO autopsy tool, membrane cleaning (CIP) chemical calculator and a CIP effectiveness predictor. • Chemistry & Pretreatment: LSI (scale and corrosion potential), chemical dosing, chlorine contact time for RO membranes, a pretreatment recommendation tool and a pretreatment risk analyzer. • Cost & ROI: RO operating cost (OPEX), RO energy cost per 1,000 gallons, RO chemical spend, membrane cleaning vs. replacement, service vs. replacement, service cost comparison, in-house vs. outsourced maintenance, and water treatment savings vs. no treatment. Built for the job site • Clean, mobile-first layout with large tap targets. • Calculators open inside the app with a clear Back button. You can also open any calculator in your browser. • If you lose signal, the app tells you so plainly instead of showing a blank screen. You can still browse the list and your favorites offline. Good to know • The calculators run on complete-water.com and need an internet connection. • Results are estimates for general reference. For design decisions on your system, talk to a water treatment professional. • The app has no ads, needs no account, and does not ask for device permissions beyond internet access.
