Multiple-Effect Distillation (WFI) is designed to comply with the specifications of U.S. Pharmacopeia (USP) Water For Injection (WFI), and in accordance with the water quality of the supplied water source. When the temperature exceeds 80°C, the purification of water quality will be transferred in two phases.
Changing to vapor from liquid, then changing to liquid from vapor. The feed water evaporates through the heat exchanger in the evaporator, and uses its latent heat to let the evaporation process through a series of 180 degree rotations by a centrifugal cyclone baffle plate device inside the separator. Forcing the particles and water drops out by the power of flow to make the vapor that leaving the baffle plate will not contain dissolved solids and pyrogens. The particles and water drops will fall to the bottom and be heated again, condensing the purified water vapor to required distilled water by condensation transferring, using a three-way valve to discharge the unqualified purity water to ensure the water quality of distilled water, and storing in a storage tank for injection pharmaceutical use.
