multistage Pharmastill distiller

It is good for replenishing each other.Gravity sedimentation has good separating effect for big and middle drop.Turbulent flow has good separating effect for small drop.Wire mesh despumation has good separating effect for micro-drop.Comparing way of third degree separating with way of spiral plate separating, the first one can increase 30% separating precision, contains endotoxin 0.0625EU/L, contains microbion10CFU/100ml. The quality of water satisfied the standard of International Pharmacopoeia.
Using structure of double tubesheet.

Using way of third degree separating. 

How to guarantee high quality of WFI?

The qualified raw water is input into the preheater after increased the pressure by multilevel pump. After heat exchanging, the raw water is entered into each preheater. Next the raw water is input into the raw water distributor of the 1st stage evaporator, which is spouted to the inside of the heating tubes. So that the raw water in the tube is flowed as membrane, which is heated by boiler steam. The produced second steam with drips is entered into the gas and steam separating setting from the bottom of the heating tubes. The separated pure steam is entered into the next stage as heating steam, meanwhile, the raw water, which is not evaporated, entered into the next stage. And then it is repeated above mentioned process. The pure steam from last stage is converged with each stages condensed water(except 1st stages), after cooling and drainage of the infusible gas, it is became the WFI with the temperature 92-99 Centigrade.
