Filter cloth issues in plate and frame filter presses
Thread Content
What material and model of filter cloth do different manufacturers use for plate and frame filter presses?
For salt sludge, our company generally uses polypropylene filter cloth or polyester filter cloth
Your question is too general. Different filtration media require different filter cloths, and there are many types of such cloths. Generally, manufacturers of plate and frame filter presses will conduct tests to help you choose the most suitable filter cloth for your needs.
It depends on what medium is being filtered. Different filtering media require different filter cloths. Filter cloths for filter presses come in two types: filter cloth pieces and filter cloth sleeves. Filter cloth pieces are made by cutting filter cloth into two sections, which are then fixed to both sides of the filter plate using filter cloth clamps； The filter cloth sleeve is formed by sewing two filter cloth pieces together with a feeding hole connecting sleeve. It is generally tied to the filter plate. The materials include polyester, polypropylene, and various types of fibers with different lengths. Generally, manufacturers will choose the material based on the properties of your materials.
Our company, Dalian Hualong, is a manufacturer of gasification ash and water filtration fabrics.
It is best to use filter cloth made of polypropylene with a plain weave.
I’m sorry, what we filter is salt sludge; the Kay membrane process does not separate barium sulfate. Could you provide the specific material model?
It is generally polypropylene felt, or a combination of 2 to 3 materials. Ceramic filter plates are gaining momentum; sintered wire meshes are also used, depending mainly on the type of slurry to be filtered
Filter cloths are not only determined by their material but also by their porosity; it depends on the size of the particles in the material being filtered as well as the size of the impurity particles, so there is indeed some knowledge involved in making the right choice.
The filter cloths for filter presses are mainly made of polyester, nylon, polypropylene, etc., depending on the acidity or alkalinity of the medium; as for the type of fibers used in these filter cloths, there are single fibers, multi-filament fibers, and a combination of both.
Your question is too general. Different filtration media require different filter cloths, and there are many types of filter cloths available
The selection of filter cloth varies depending on factors such as filtration pressure, medium properties, and medium temperature! It’s true that many filter press manufacturers are quite amateurish. There are those that specialize in providing filter cloths; be more attentive to that.
There is indeed a lot to know about filter cloth filtration; if you are looking for products with a filtration precision of less than 1 micron, you can contact Shenyang Feite Filter Media Machinery Technology Co., Ltd
For 13# Feiteco salt mud, polypropylene 750A or the enhanced version 750B can be used; twill fabric is better than plain fabric in terms of preventing the formation of mud cakes
