Calculate filter backwash volume, frequency, and supply requirements for water treatment plant filter maintenance.

Calculate chlorine dose and feed rate for water disinfection, including CT compliance for pathogen inactivation.

Calculate alum, ferric chloride, or PACl feed rates from jar test results. Estimate alkalinity consumption and sludge production.

Calculate the Langelier Saturation Index (LSI) and Ryznar Stability Index for pipe corrosion prevention in drinking water.

Calculate filter area, media volume, and backwash requirements from flow rate and loading rate.

Calculate chemical feed rate for water fluoridation to achieve target concentration using NaF, fluorosilicic acid, or sodium fluorosilicate.

Calculate permeate flux, transmembrane pressure, and fouling indicators for membrane filtration systems (MF/UF/NF/RO).

Estimate sludge production from water treatment including turbidity removal and chemical addition. Size lagoons and estimate disposal costs.

Calculate UV dose and reactor sizing for pathogen inactivation based on flow rate, UVT, and target log reduction.

Size a water treatment plant from population, per-capita demand, and peak factors. Estimate basin, filter, and clearwell dimensions.
