Our multi-effect stills use pure water as feed water and use industrial steam heating to produce water for injection (WFI). SKE’s LDS series of multiple effect stills use the same principle to produce Water for Injection (WFI) using industrial steam. The final product meets the requirements of the United States Pharmacopoeia (USP), European Pharmacopoeia (EP) and Japanese Pharmacopoeia (JP), ensuring it is suitable for pharmaceutical applications.
316L Stainless Steel Distillation Equipment Working principle
Qualified feed water will pump into the condenser after increased the pressure by multistage centrifugal pump.
Then pump into each preheaters.
Get into 1st stage evaporator, spray into internal of heater to create film flow, heated by industry steam to create pure steam & water mixture.
Non condensate water will move to 2nd stage evaporator. Pure steam will be heating medium for 2nd stage evaporator.
Pure steam from last stage mix with condensate from each stage evaporator ( except from 1st stage), discharge non condensate gas, become WFI after feed water analyzer.
