Purified Water & WFI generation for regulated plants
A compliant PW/WFI system is designed backwards from the point-of-use specification. The pharmacopoeia grade, peak and average demand and sanitisation method fix the basis; pre-treatment then protects the membranes, generation (hot-water-sanitisable RO with EDI for PW; distillation or Combi units for WFI and pure steam) produces water at grade, and a 24/7 recirculating loop holds it at grade to every user point.
The common failure mode is designing each unit in isolation — a generation skid that cannot hold conductivity because the loop velocity or sanitisation strategy was fixed too late. DFT captures the raw-water analysis, demand profile and user-point layout and coordinates the whole journey with Praj HiPurity so pre-treatment, generation, storage and distribution are consistent. Final engineering, qualification and validation are confirmed per project.
