Case Studies

This BoHiBar drum filter is operated for steam pressure filtration of an organic acid. The suspension coming from the reactor consists of organic crystals suspended in water and is enriched with salts that are completely dissolved in the filtrate.

The BoHiBar drum filter is equipped with exchangeable filter cells and is designed for steam pressure filtration It is operated to filter, wash and dewater fine-grained (x₅₀ < 5 µm) high quality inorganic pigments.

This BoHiBar drum filter is operated for an intensive wash and drying of an organic crystallization product by steam pressure filtration to obtain a high purity product.

In a BDO production plant (butanediol process) 24 BoCross MicroScreen filter units of 10 m² each are applied for recovery of catalyst by dynamic precoat filtration.

From a high valuable polymer dispersion coarse particles (x > 20 µm) have to be separated completely. The difference in density of the particles compared to the fluid is negligible.

The BoCross Dynamic Filter is used for concentrating and washing of a modified and very fine titanium dioxide which has to be further processed.

A pharmaceutical suspension is synthesized so that a considerable amount of salt is formed during neutralization. This microfine suspension must be cleansed (washed out) of salt and further concentrated.

For concentrating a fine-particulate special PCC product a BoCross Dynamic Filter with 6 m² filtration area is operated.

The BoVac Drum filter with 1 m² filter area is operated in parallel to a 12 m² belt filter for filtration and washing of gypsum.

The BoVac Drum filter is operated for filtration, washing and dewatering of an organic pharma intermediate. The filter is encapsulated and equipped with 3 adjustable wash bars with full cone spray nozzles and with a CIP system.

The BoVac Drum filter is operated for filtration, washing and dewatering of a textile dye product. The filter is equipped with a wash hood and adjustable wash bars with spray nozzles and with a CIP system for clean & safe operation.

Four BoVac Drum drum filters are operated for filtration, washing and dewatering of fine sized tarnishing pigments. Each of these modern 5 m² vacuum drum filters replaces one 8 m² drum filter of old design.
