Use Of Filter Fabrics As A Filtration Media
March, 31, 2012
Filter Press Cloth is a distillation medium that is installed in different types of Filter Presses such as Chamber Press, Membrane Filter Press, etc. Filter Press Cloth works as cleansing medium in the Filter Press – the equipment required for the completion of filtration process in a number of manufacturing and processing units. Several industries such as Food Processing, Chemical and Pharmaceutical, use Filter Press for material filtration and therefore, frequently need Filter Press Cloth. Filter Press Cloth is generally made of two types of materials- woven and non-woven. Here, we will discuss both of them.
Woven Fabrics:-
Filter Press Cloth, made of woven fabric, is mainly required as distilling element in the pressure Filter Press kit. Woven Filter Press Cloth is quite convenient to distill the solid particles from the liquid. This type of Filter Press Cloth is specifically designed in a pattern that facilitates easy trapping of the solid particles and then smooth flow of the liquid. The Woven Filter Press Clothes have the capability to withstand heat, powerful chemicals and abrasive properties of the insoluble particles. The different types of woven fabrics are used to fabricate:
- Centrifugal bags
- FBD bags
- Nutch filter bags
- Vacuum filter bags
- Sparkle filter bags
- Filter press sheet
- Cotton cloth
- Polypropylene cloth
- Polyester cloth
- Filaments
- ETP panel filter
- Electroplating bag
Non-Woven Fabrics:
Filter Press Cloth made of non-woven fabric is purposefully designed in mesh structure. Non-woven Filter Press Cloth can be fabricated either by using mechanical process or thermally. Besides, different chemicals are also used to fabricate Filter Press Cloth. Filter Press Cloth made of non-woven materials are absorbent, smooth and come in the form of sheets. In terms of strength and pattern, the non-woven Filter Press Cloth is somewhat like the woven fabric Filter Press Cloth. Additionally, it has very thick wadding. The Woven Filter Press Clothes can be customized by using the combination of different types of materials. Apart from making the Filter Press Cloth, the woven fabrics are also used to make various industrial clothes such as surgical gowns, upholstery products, etc.
Advantages Of Non-Woven Fabrics:-
- Highly absorbent
- Liquid repellent
- Resilient
- Stretchable
- Soft
- Frame retardant
- Washable
- Good filtering quality
Industries that require Filter Presses definitely need Filter Press Cloth as essential Filter Press Accessories. Given that, the Filter Press Cloth is available in woven and non-woven types to choose from. However, selection of the most appropriate material is necessary so as to ensure trouble-free filtration process.
