Treatment train designer

What it does

• Scores every determinand on the certificate against SANS 241, with the dual aesthetic and health limits where the standard carries both
• Builds the treatment train in the order the chemistry dictates: oxidation before filtration, iron removal before resin, dechlorination before any membrane
• Injects prerequisites (a pH raise before iron or manganese oxidation) and flags steps that stay blocked until they are met
• Catches interferences and by-products: tannin-bound iron, sodium added by softening, hardness added by calcite, aggressive RO permeate
• Sizes each step off the design flow when the branch quotes it: vessel and valve from DWT's FlowShell and Runxin data, softener resin volume, RO elements and recovery, chemical feeds, carbon contact volume, UV duty
• Predicts the finished water and re-checks the whole panel, so anything the treatment itself breaks is shown as induced
• Computes the Langelier index at supply temperature and at 60 °C, and the SAR for irrigation
• States the GN 665 of 2013 disposal route for RO reject, softener brine and filter backwash
• Checks the certificate itself: unit slips, dissolved above total, hardness that does not match its calcium and magnesium, ion balance
• Scores irrigation and livestock water against the DWAF guidelines rather than the drinking-water standard
• Links every step to the relevant DWT range, calculators and knowledge base, and hands the design to a quote request in one click

Results are indicative engineering estimates, not a design service: the branch sizes and confirms every selection against the full certificate and manufacturer data before anything is quoted. Trade customers with a DWT access code see the sizing and bill of materials live.
