Filter cloth manufacture

Fabrication of filter cloth is a complex and multistage process, from filament basic material selection to finishing treatment of the end product. Filter cloth acts as a filtering partition and should combine the optimal ratio of the filtration flow rate and clarity of filtrate. In addition, by no means unimportant role plays the chemical and mechanical resistance of the material, the efficiency of regeneration, a minimum adhesion of sludge and subset of other parameters, which together determine the selection of a actual type of filter cloth for a specific process.

ChemInS LLC controls and can adjust the production of filter cloth from manufacture of threads to the type and the method of final processing of the fabric, glossing parameters and thermostabilisation, heat setting. That is why we can supply filter cloth and their products for a specific filtration process to achieve maximum efficiency.

Application

Filtration through filter cloth is used in many different kind of industries. Its task is the separation of solid particles from liquid or gas according to the principle of the sieve mechanism. In addition to mechanical processes often need to take into account the physical and chemical aspects of filterable media: the adhesion of the produced sludge, potential of colloidal components. Depending on the type of equipment that uses a filter cloth, and the conditions of the process to the finished filter element must meet different requirements.

The presence of our company experience in the selection and supply of filter cloths and products from them to various industry sectors for different kind of equipment is a guarantee of quality of products we offer and guarantee efficient operation of your filtration equipment.
