Bokela BoHiBar Filtration

BoHiBar filtration; • When fine particles need to be filtered, • When clean product or very low cake moisture content is desired, • When high process pressure and high temperature are required, • When contamination prevention is necessary, offers unique solutions. Bokela BoHiBar steam pressure filtration is an innovative hybrid process developed by Bokela. BoHiBar steam pressure filtration provides the lowest moisture content and highly effective cake washing. Applications: White and colored pigments, calcium carbonate (PCC), melamine, PVC, PTA/CTA/QTA, SiO₂. Bokela Continuous Rotary Vacuum Filters Continuous operation rotary filters offering high-performance capacity and requiring small footprints represent the most economical solution for numerous solids-liquids separation operations. • BoVac Disk filters are available in various diameters and variable numbers of filter disks. Their modular design allows adaptation to specific process conditions. • BoVac Drum filter is known for excellent cake washing and rapid filter cloth change. Cloth replacement can be completed in approximately 1-2 hours without stopping production. BoVac drum filters feature replaceable filter cells. Applications: Color pigments, white pigments such as calcium carbonate and titanium dioxide, gypsum, potassium sulfate, caffeine, pectin, salts, zinc sulfate, zinc sulfide, catalysts, starch, crystallization products. • BoVac Pan filter features horizontal filtration surface and is particularly suitable for effective cake washing. For this reason, it is preferably used for filtration and washing of coarse-grained and rapidly settling suspensions. Bokela Cross-Flow Filtration • With BoCross Dynamic filter, micro and nano-scale suspensions can be concentrated up to high concentrations. Cross-flow filtration is a unique process for microfiltration and ultrafiltration of suspensions from microfine to nano scale. Applications: White pigments such as barium sulfate, kaolin and titanium dioxide, nano-scale products, dextrose, soy milk, pharmaceuticals. • BoCross Screen filter is preferred when suspensions need to be classified or when complete recovery or separation of solids is required. Applications: Polymer suspensions, melamine, cocoa butter, catalysts.

Filter Retrofit – Modernization and Optimization of Operating Filters

Filter retrofit is an economical alternative to new filter investment. Filter retrofit enables customers to optimize the process and operation of their already operating filter system in the fastest and most economical manner. Disk, drum and pan filters from numerous OEMs have been successfully optimized by Bokela. • Increase in solids processing capacity from 30% to 150%, • Reduction in cake moisture, • Improved filter operation, maintenance and safety, • Increased filter operation performance, • Significant investment savings – filters can be retrofitted with only 10% to 30% of the cost required for new filter investment, • Quick solution within maintenance/operating budget without need for capital investment process.
