With over 300 employees and a number of subsidiaries, BHS-Sonthofen has a global presence. Cake filtration BHS has specialized in cake filtration for more than 50 years. We supply a broad range of pressure and vacuum filters for both batch and continuous operation. There is a diverse...

RUBBER BELT FILTER 4 BHS rubber belt filter The BHS rubber belt filter is a continuously operating, horizontal vacuum belt filter used for the quick and efficient separation of sedimenting solids from suspensions. It is characterized by its high throughput rates and robustness. Cake treatment with single or multi-stage washing is possible. BFR 120 rubber belt filter

Robustness The BHS rubber belt filter stands out for its robust design which is optimized for operational use. A stable, load-bearing design made of steel or stainless steel allows this system to be used even in rough environments. The BHS rubber belt filters are designed to achieve a long service life under high loads. This minimizes the maintenance and operating costs. Easy maintenance Thanks to the low number of installed individual components, rubber belt support provided by a roller table and the optimal accessibility of the vacuum box, the rubber belt filter is extremely...

A rubber belt is used to support the filter medium. The rubber belt is provided with milled grooves for filtrate discharge. It runs on a roller table and on wearing and sealing belts over a stationary vacuum box, where the filtrates are collected and discharged. The...

Roller table Vacuum box with wearing belt Using the roller table eliminates the use of consumables such as compressed air or water. Tried-and-tested roller systems support and guide the rubber belt. This system offers high reliability with low maintenance requirements. There is a vacuum box under the filter which connects the vaccum to the rubber belt and thus to the filter cloth. Wearing belts with a sealing water supply enable optimal protection against atmospheric conditions. The vacuum box can have a plastic or stainless steel design. Easy accessibility and decreased need for sealing...

AREAS OF USE AND POSSIBLE APPLICATIONS 8 Flue gas desulfurization Large quantities of gypsum are formed during flue gas desulfurization by wet scrubbing. To ensure high-quality gypsum, the quality specifications for chlorides and residual moisture must be reliably met. The BHS rubber belt filters have been a well-proven solution in this application for many years. Due to integrated washing and drying zones, the required quality is continuously met so that the gypsum can be easily marketed or processed. Mining products, ore, metals Wet mechanical separation procedures are often used in the...

Filtrate separator station Filtrate separator stations are used for the separation of gaseous and liquid media. The filtrates are pumped out of the separators using appropriate pumps or are barometrically drained. The gas is conveyed to the vacuum pump unit through a common manifold. Vacuum pump unit An optionally available vacuum pump unit can be used to generate the vacuum for the rubber belt filter. This creates the v ­ acuum pressure required for the rubber belt filter to operate correctly. For complete systems, liquid ring pumps are normally used for this purpose. Hydrocyclone station...

Tests give certainty We perform initial tests with our pocket leaf filters. These tests can be performed quickly and easily at your location or in our well-equipped laboratories worldwide. Basic data can thus be obtained about the filterability of a suspension and the general design of a production filter. For more extensive tests, even spanning several weeks, we can rent out pilot and lab filters for all BHS filter types. Filters made of different materials are also available. If necessary, the filters can be equipped to meet specific customer requirements. These filters can be used to...
