Indexing belt filter (BF)

The BHS indexing belt filter (type BF) is a continuously operating, horizontal vacuum filter used for the efficient and also gentle separation of sedimenting solids from suspensions. Through various process steps, the filter cake forming on top of the belt can undergo diverse treatments. As a result, the filtrates can be individually recovered and processed. The BHS belt filter thus offers very high process versatility.

Pressure plate filter (PF)

The BHS pressure plate filter is a batch-operated filter with plate-shaped filter elements arranged one above the other inside a pressure vessel. The filter cake builds up on the filter plates. The clear filtrate is discharged inwards through the hollow shaft. All process steps are carried out under pressure. Cake discharge is accomplished by vibration of the filter elements.

Retrofitting in amino acid production: BHS supplies rotary pressure filters for the dietary supplement industry
L-threonine is an essential amino acid in both the animal and human diet and is produced on an industrial scale across the world. An American manufacturer of dietary supplements was using outdated horizontal automated filter presses to filter L-threonine crystals. BHS-Sonthofen tested its different filter systems for use in this challenging filter application. Together with the customer, BHS-Sonthofen decided on rotary pressure filters as a high-performance alternative that also optimally suits the existing production process.
