From BHS-Filtration Inc.
In many chemical and pharmaceutical processes, solid-liquid separation, cake washing and drying steps directly impact the effectiveness of the production operation. Process engineers devote much of their time to analyzing these steps.
The solid-liquid separation step can be by pressure, vacuum or centrifugation as well as in a batch or continuous mode. In this separation step, there is a further choice both of the type of filter media and the thickness of the cake or the cake depth during which the separation occurs. Cake washing generally follows and the choices are displacement or reslurry options. Finally, drying may be necessary and there are many possibilities including vacuum, convection, spray, steam and a combination of techniques.
Products & Services
Filtration Equipment
Filtration equipment is used to filter, thicken or clarify a mixture of different elements.
Dewatering Equipment
Dewatering equipment uses force, including vacuum and centrifugal motion, to separate water from solids.
Clarifiers
Clarifiers and screens are used to remove solids from liquids through gravity settling or a mechanical screening process.
