Thin-Cake Filtration Technologies for Removing Activated Carbon, Catalysts and Other Trace Solids from Active Pharmaceutical Ingredient (API) Slurries

BHS-Filtration Inc.

The BHS technologies of Vertical Candle Filters and Horizontal Pressure Plate Filters provide improved product quality with more efficient operations compared with manual pressure filters. The different technologies allow for the selection of the optimum process solution depending upon the cake characteristics and cake structure. Fully automatic operations provide for complete containment of the solids and liquids for reduced maintenance costs and overall project savings.

BHS Candle Filter technology for refinery applications

BHS-Filtration Inc.

Application Summary from BHS-Filtration Inc. to BHS Candle Filter technology for refinery applications: Candle Filters provide for thin-cake pressure filtration, cake washing, drying, reslurry and automatic discharge as well as heel filtration in an enclosed, pressure vessel. Units are available from 0.17 m² up to 100 m² of filter area per vessel. The Candle Filters are installed for clarification and recovery applications from liquids with low solids content. They are an ideal replacement for filter presses as well as for manual plate filters, bag filters, cartridges filters and other conventional-manual separation equipment where solids, solvents and hazardous materials are being handled.

Flexible mechanical approach

Recycling aktiv

The Rotorshredder RS and RPMV Rotor Impact Mill from Germany based BHS Sonthofen achieve the main objectives of processing waste from electrical and electronic equipment (WEEE), namely the effective size reduction and gentle "disintegration" of composites in order to liberate individual components. This approach is regarded by the manufacturer as extremely flexible and cost efficient.

Mechanical Processes for Recycling Waste Electric and Electronic Equipment with the Rotorshredder and Rotor Impact Mill

AUFBEREITUNGS TECHNIK

In plants for the recycling of waste electric and electronic equipment (WEEE) as well as for conven-
tional mineral processing, the comminution equipment dictates whether and how the specifications for the separation and sorting of the feed material are achieved. For the comminution of WEEE, the machi-
nes must meet specific requirements in respect of size reduction, insensitivity to solid components and flexibility for adapting to different feed materials. To liberate single components, composites must be broken up, but harmful components that are contaminated with pollutants should not, however, be destroyed completely. With the Rotorshredder RS and Rotor Impact Mill RPMV presented here, BHS Sonthofen supplies two machines to achieve the main objectives of WEEE processing ­ i.e. effective size reduction and gentle desintegration of composites to liberate the individual components. The achievement of these aims in combination with an extremely flexible and at the same time costeffi-
cient operation represents a leap in technology compared to conventional systems.

Mixing special concretes

BFT INTERNATIONAL

As a result of recent new developments throughout the concrete industry over the past years, the re-quirements placed on the concrete production process, as well as the complexity of the mixing tasks, have considerably increased. This situation confronts suppliers of mixing machines with the tasks of systematically acquiring new knowledge on the operation and the functioning of their machines, and of developing suitable solutions for the challenges that arise.
