Eighteen design sheets: pipework and pumps, four routes to solids separation, media and carbon filtration, ion exchange, the whole membrane range from microfiltration to reverse osmosis, continuous electrodeionisation, UV disinfection, heat transfer and chemical reaction tanks. Each sheet gives the governing equations, the design envelope industry practice actually accepts, and a calculator that recomputes as you type — so you can size a train in the browser before you open a spreadsheet.
The full method, the equations and the calculators stay open. If a sheet saved you an hour, the most useful thing you can do is share it with the engineer who needs it next.
Share this pageEvery sheet on this page as a linked Excel workbook — unlocked formulas, unit-consistent, with a datasheet tab, an equipment list and a printable calculation record for design submissions.
Independent sizing, basis-of-design documents, tender technical evaluation, and second-opinion review of vendor proposals for industrial water and wastewater trains.
A short note on one design decision — a sizing rule, a failure I have seen, a number worth remembering. No vendor content.
