World Filtration Congress (WFC 10) BOKELA will participate on the 10th World Filtration Congress in Leipzig with an exhibition booth and will report on following topics:
We are looking forward to meet you on our booth A7/B11, Congress Center Leipzig, Hall 2 20.12.2007 TMS 2008 - 137th Annual Meeting & Exhibition BOKELA will participate on the TMS 2008 annual meeting from 9 to 13 March 2008 in New Orleans. BOKELA reports on the following topics on the Bauxite and Alumina session:
10.12.2007 Vacuum Drum Filters for Filtration & Washing of a Silicon Product BOKELA has been awarded an order from a German producer of a silicon product to supply 4 vacuum drum filters of high performance design for the chemical industry. Each filter has a filter area of 5 m² and is equipped with exchangeable filter cells and cake wash device. The nominal solids throughput of 180 kg/h can increase to nearly 300 kg/h. The filters are characterized by high specific capacity, flexible operation and low maintenance due to their modern design. The new BOKELA drum filters will replace 4 drum filters of old design with a total filter area of 32 m². 10.12.2007 Pilot Drum Filter for Brine Leaching Process A major German salt producer has selected BOKELA to supply 1 pilot vacuum drum filter of high performance design. The filter was delivered to its destination at the beginning of December. The 1 m² filter will separate crystals from a new brine cooling process of pilot scale which will be operated for testing the feasibility of the new process. Main parts of the filter like trough, control head, filtrate pipes and receiver are isolated to prevent formation of condensate/ice. 18.11.2007 Two Boozer Disc Filters started Operation Two Boozer disc filters L4 (176 m² filter area each) started operation of fine seed filtration in an Australian Alumina Refinery. These 5th generation Boozer disc filters represent the most modern high performance disc filter design and were ordered by the client to replace drum filters of old design and to make the refinery fit for an plant upgrade. The two Boozers were commissioned by BOKELA engineers and started operation successfully. [Boozer] 15.7.2007 Vacuum Drum Filters for Filtration & Washing of Gypsum A German producer of chemical products has selected BOKELA to supply 2 chemical vacuum drum filters of high performance design for separating precipitated gypsum from the valuable filtrate. A filter cake wash improves both filtrate recovery and purity of the gypsum which is used for medical purposes. The new drum filters of 2 m² each are equipped with exchangeable filter cells, cake wash device and hood with inspection window. The filters will replace a belt filter and have been chosen by the client to improve solids capacity, cake wash, moisture content and to reduce maintenance, repair and operation cost. 17.8.2007 Aluminium of Siberia, Russia BOKELA will take part to the conference “Aluminium of Siberia” which will take place in Krasnoyarsk, Russia on 11-13 September 2007. BOKELA will give presentations on:
26.6.2007 New Vacuum Disc Filters for Brazil ALUMAR, a big Brazilian alumina producer, is extending its production capacity by adding new equipment. BOKELA will thus deliver 9 new disc filters Boozer L-Type to the refinery. The filters will be operated both in fine and coarse seed areas. [Boozer] 26.6.2007 Upgrading of Kaolin Drum Filters An
American kaolin producer is upgrading its vacuum drum filters in order
to improve the filter capacity. A first study showed that an increase by
at least 45% can be reached for the main kaolin grades. The throughput
increase of the fine grades will be 30%. |
