Engineering Calculators
Empirical flow rate, adsorption kinetics, and membrane flux estimators built on global engineering codes.
System Estimation Suite
Activated Carbon Sizing
Analyze contaminant loading and calculate precise carbon usage rates and vessel geometry.
Chemical Dosing & Dilution Calculator
Calculate continuous chemical consumption for antiscalant, SBS/SMBS dechlorination, and DBNPA biocide, then work out day-tank batch mixing and metering pump flow rate.
Cooling Tower Water Balance & LSI Calculator
Calculate evaporation, drift, blowdown, and makeup water balance for cooling towers, with a Langelier Saturation Index model that dynamically flags scaling and corrosion risk in the circulating water.
Ion Exchange Resin & CEDI Designer
Size ion exchange resin vessels and regeneration chemical consumption for softening, cation, and anion demineralization duty, plus Faraday's-Law-based DC current and power estimation for a downstream CEDI polishing train.
NF System Designer
Model nanofiltration mass balance with independent monovalent (salt) and divalent (hardness) rejection tracking across up to 3-stage arrays, plus a solver for the bypass blend needed to hit a target finished hardness.
Ozone Dosing & CT Calculator
Size the ozone generator for a target applied dose, then verify EPA Cryptosporidium CT compliance for the contact basin at your actual water temperature, baffling factor, and residual.
Pipe Friction & Pressure Drop Calculator
Model friction loss, fitting/valve losses, and elevation change for a single pipe run across common pipe materials, with temperature-dependent water properties.
Pipeline Air Valve Layout & Sizing
Determine air valve type, spacing, and sizing along a pipeline from pipe length or a full elevation profile, with anti-slam flagging at high-risk points.
Pneumatic Actuator Selector
Select correctly sized pneumatic or electric actuators for quarter-turn valves based on required torque, safety factor, and air supply pressure.
RO System Designer
Model permeate flow, recovery ratio, and concentrate TDS across multi-stage RO arrays, with membrane fouling and osmotic pressure checks.
UF/MF System Designer
Size an ultrafiltration or microfiltration membrane array from design flow, balance backwash water against system recovery, and lay out membrane trains with a live array topology visualization.
Unit Converter
Convert flow rate, pressure, concentration, membrane flux, and other water treatment engineering units instantly across 9 dedicated category converters.
