Pharmaceutical Water Treatment
Water is used in pharmaceutical process manufacturing for sanitation, cleaning and rinsing and as part of the drug formulation make-up. The stringent quality of the water is defined by the regulatory or pharmacopeia bodies within the respective regions. The two main classifications for bulk treatment in pharmaceutical water systems are Purified Water (PW) and Water for Injection (WFI). The regulatory agencies make recommendations on how water should be processed - generally Cartridge Filtration, Reverse Osmosis / Deionization (RO/DI) for Purified Water followed by distillation for Water for Injection. Cartridge filtration may be used for particle removal (trap filters), Bioburden reduction and sterilisation of water. Vent and Gas filters are used for filtering the displaced air from pathogens as the tanks fill and empty.
