Principle of operation:
It is based on the filtering ability of elements made of porous permeable ceramics that remove insoluble solids from liquids that pass through them. Cartridge ceramic filters are based on pressure filtration. Liquid is supplied into the cartridge ceramic filter, forced through the ceramic pores into the inner cavity of the cartridge elements and discharged from the unit via manifolds. At the same time, the cake formed on the outer surface of the cartridges, in turn, acts as an additional filter layer. As the cake thickness increases, the cartridge ceramic filter capacity decreases, and upon reaching a certain thickness, the filtration process stops. Cake is discharged from the cartridge element surface by the backflow of compressed air or filtrate. The cake, suspension and filtrate residues are removed from the cartridge ceramic filter housing by compressed air or hydrostatic pressure
Applications:
The filters are used for filtering a wide range of suspension classes and are suitable for separation of suspensions with small solids concentrations and high-temperature suspensions that can't be cooled due to crystal crashing out.
Efficiency:
The use of nanodispersed binder based cartridge ceramic filter elements developed by Bakor ensures 100% filtration of solids, enables setting up closed-loop water-recycling systems, extraction of valuable substances from tailings and burial of dry solids at minimum cost and maximum performance.
Main advantages (compared to competitors):
Advantage | Bakor specification | Typical of competitor cloth based filters |
Ability to select pore diameter for a specific task | 1-100μm | 10-100μm |
High strength | Compression strength above 32 MPa | One or two parameters that are not inferior to BAKOR ceramics can be chosen, but not all of them simultaneously |
High simultaneous chemical resistance to a wide range of substances | Acid resistance over 97%, alkali resistance – min. 90%, absolute resistance to organic solvents | |
High temperature applications | Limited only by the medium's boiling point | |
Increased element service life | Depending on the task, can reach several years | 1-2 months |
Ability to get crystal-clear filtrate without additional clarification stages |
less than 0.02 g/l | Particulate arresting efficiency usually does not exceed 98% at the start of operation, with a standard average particle size of min. 10μm |
The main advantage of filters using ceramic candles as a filter membrane is that they can SIMULTANEOUSLY combine many properties, which are either very difficult to obtain or which have to be selected to the prejudice of others with cloth filters. These include high strength, chemical and temperature resistance, improved wear resistance and longer service life. At the same time, ceramic filters provide an essential ability to obtain a homogeneous filtration surface with minimum pore sizes, which are actually not achievable with woven materials. This enables to get crystal pure filtrate without additional clarification stages or pre-coated layers.
