LDS series Multi-effect water distiller adopted the purified water as the feed water, produced WFI by heating industrial steam. The product satisfies the requirement of CGMP (CP2010), USP34 and EP7.
The qualified feed water is input into the condenser after increased the pressure by multilevel pump. And then enters into each preheater (the feed water will be heated by the secondary steam and distilled water in the condenser, in the fist stage preheater, the feed water heated by the industrial steam condensate water, after enters the other stages preheater, it is heated by the secondary steam condensate water). Next the feed water is input into the water distributor of the 1st stage evaporator, which is spouted to the inside of the heating tubes and flowed as film. The produced second steam with drips enters into the gas and steam separating setting from the bottom of the heating tubes. The separated pure steam enters into the next stage as heating steam, meanwhile, the feed water, which is not evaporated, enters into the next stage. And then it is repeated above mentioned process. The pure steam from last stage is converged with each stage condensed water (except 1st stage), after cooling and drainage of the non-condensable gas, (according to different model, there should be a device for discharge the non-condensable gas continuously) it is became the WFI. There is an on-line conductivity test at the output orifice, the qualified distilled water will be output as the WFI, and the unqualified will be discharged.
1. Structural form: External preheater, condenser and the first effect evaporator are all double tube plate designed.
2. Separation device: the feed water enters the equipment will under three stage separation that is film evaporation, gravity separation and special separation device.
