Turn the question into a controlled engineering duty
Set membrane duty from feed chemistry, pretreatment, permeate quality, recovery, flux, temperature, cleaning and concentrate constraints. The acceptance basis must resolve feed-water analysis and temperature together with permeate quality and demand profile, then assign operating limits, responsible roles and controlled records for this exact task. Control source rights and variability, product identity, mineral and sensory targets, package formats, production calendar, hygienic zoning, finished-water release and local water, food, environmental and labeling responsibilities. Separate raw, treated, ingredient, rinse and utility-water specifications; record seasonal sampling coverage, treatment recovery, sanitation overlap, laboratory turnaround, packaging supply and warehouse demand so that source yield and saleable output can be reconciled on the same schedule. Record every input with units, source, approval status, credible range and decision owner. Keep an unknown visible when it can change sizing, hygiene, packaging, automation, utilities, cost or schedule.
