Eighteen unit-operation design sheets with live calculators, a chemical compatibility matrix, and a linked Excel workbook. Built by a process engineer for people who have to size the equipment and sign for it.
Every section, with what it sizes and how many sheets it holds.
Pipe sizing from velocity, Darcy–Weisbach head loss, pump total dynamic head, NPSH available and specific speed.
Circular and rectangular clarifiers, dissolved air flotation, lamella packs and graded media filtration — overflow rate, scour and backwash.
Carbon bed contact time, usage rate and service life; resin volume, service flow rate, regenerant demand and cycle availability.
Microfiltration through to reverse osmosis — design flux, transmembrane pressure, array staging, tail-element scour and specific energy.
Continuous deionisation: feed conductivity equivalent, ionic load, Faraday current, stack voltage — and the feed specification that governs whether it works at all.
UV dose from fluence rate and residence time, with the validated equivalent; heat exchanger duty, log mean temperature difference and fouled surface area.
Velocity gradient, Camp number and impeller power for mixing and flocculation; reagent demand, dosing pump duty and staging for pH correction.
Thirty water treatment chemicals against eighteen materials of construction, plus the eight pairings that fail most often in real plants.
Every sheet as a linked Excel workbook — unlocked formulas, water properties from your temperature, automatic envelope checks, equipment list and calculation record.
