At AchemAsia, this engineering company presented its range of filters and filtration plants for the chemical, food, biotechnology and environmental industries. For example, the Hi-Bar range of continuous pressure filters is said to offer new solutions for filtration, washing and dewatering of fine-grained suspensions. Working pressures range up to 15 bars (absolute). Hi-Bar plants are available with horizontal pressure vessels for large units, and as Oyster Filters (photo) with vertically opening vessels for smaller, challenging applications in the chemical, pharmaceutical and food industries. Other types of available filters include drum filters, with filter sizes of 0.5 to 125 m2; the Dyno Filter, a dynamic crossflow filter for ultra- and microfiltration that enables thickening of suspensions to “unmatched” high concentration and simultaneous washing; and the Boozer disc filters, which are mainly used in raw-materials sectors, such as alumina refineries, coal and iron-ore processing. — Bokela GmbH, Karlsruhe, Germany
