Filter cloth selection: An indispensable key step in solid-liquid separation

As a key component in the solid-liquid separation process of filter presses, the performance of filter cloth directly affects the filtration effect, filter cake quality, and production efficiency. Filter cloth selection should comprehensively consider three aspects: material type, yarn type, and weaving structure. Common filter cloth materials such as polyester, polypropylene, nylon, and vinylon each have different acid and alkali resistance, temperature resistance, and mechanical strength characteristics; yarn types such as monofilament, multifilament, and staple fiber affect the surface characteristics and particle retention efficiency of the filter cloth; weaving structures (plain weave, twill weave, satin weave) further determine the permeability and wear resistance of the filter cloth. Based on different operating conditions, such as acidic or alkaline environments, particle size requirements, filter cake removal difficulty, and wear resistance needs, scientifically and reasonably selecting filter cloth can significantly improve the efficiency and economy of solid-liquid separation, extend the service life of equipment, and reduce operating costs.

Industrial filter cloth air permeability, pore size, and mesh conversion table and its applications!

In industrial filter cloth applications, the scientific matching of air permeability, pore size, and mesh count is key to improving filtration efficiency and extending equipment life. As industrial needs develop towards higher precision and efficiency, high-mesh filter cloths will play an important role in ultra-fine filtration. By thoroughly understanding these technical parameters and making reasonable selections based on specific process requirements, enterprises can achieve more efficient production and stable operation. Xiamen Citius will continue to be committed to technological innovation and provide excellent filtration solutions for global customers.

Industrial filter cloth air permeability (air permeability) unit conversion and selection guide

Air permeability is a key performance indicator for industrial filter fabrics, but its unit varies by region, so it is necessary to pay attention to the conversion relationship between units when selecting. Air permeability and filtration accuracy cannot be directly converted and need to be comprehensively evaluated in conjunction with other parameters. In practical applications, it is recommended to prioritize operating conditions and sample experiments to select the most suitable filter fabric product.

Cross-flow filtration filtrate flow rate and purity

Higher flow rates, pressure, and temperature can increase flow; smaller filtration channels can also enhance flow. The presence of polymer solutes reduces flow, as is the case when filtering milk. In the absence of backwashing, the flow rate of microporous membranes continuously decreases. The flow rate of semipermeable membranes decreases much more slowly than that of microporous media. This is because semipermeable membranes do not experience pore blockage. This indicates that replacing ultrafiltration membranes with microporous media is ineffective.

Comparison of Cross-Flow Filtration Media

When filtering tap water, using microporous media can achieve a very high flow rate. However, when filtering suspensions, the microporous media quickly becomes clogged, and the flow rate drops below that of the membrane.

Using dynamic membrane cross-flow filtration for oil emulsions

First, install the microporous membrane AN450 (0.45μm) in the No. 2 filter chamber shown in the table (filter chamber), and then conduct a dehydration test on the emulsion containing 1% soluble oil using the dynamic membrane formed on this microporous support.

Application of Ceramic Tube Bundle Cross Flow Filter

Concentration of milk. The pore size of the effective layer of the filter tube is 0.2μm, with a production capacity of 80L/(m2 • h). The walls of the above filter tubes are made of the same material, while the filter tubes produced by the French company Tech-Sep use powder-sintered porous carbon as the support layer and zirconia as the effective layer. For microfiltration filter tubes, the nominal pore sizes of the effective layer are divided into two grades (0.08μm and 0.14μm).
