1. Filtration rate and filtration rate per unit of time through the unit filter area filtrate volume called filtration rate, namely: u = V / Atm3 / m2 where: A – filter area, m2;? T – filtration time, ? V – the volume of filtrate flowing out in time t, m3 the volume of filtrate […]

1. Filter medium? The main role of filter media is to support the filter cake, must have a porous structure, sufficient mechanical strength and flow resistance as small as possible, corrosion resistance. In this case, Commonly used filter media are of the following types: In this case, ① fabric media, such as industrial filter cloth, […]

① Sieve Filter Filtration medium pore size is less than the diameter of solid particles, relying on the role of sieve solid particles removed from the suspension. In this case, Screening and filtration In the early stage of filtration, fine particles flow out, and the filtrate is turbid. As the cake layer is formed and […]

How to improve the filtration efficiency of the filter? Today, whether it is metallurgical or chemical industry, the filter can be seen everywhere. So how to improve the filtration efficiency of the filter? This is the common doubts of everyone’s mind. So the filter can improve the filtering effect? Filter how to improve the filtering […]

The use of porous filter media on both sides of the pressure difference, the separation of solid materials and water machinery. Filter is the use of porous filter media, trapping liquid and solid particles in the mixture of solid particles, and solid and liquid separation equipment. Filter is widely used in chemical, petroleum, pharmaceutical, light […]

Centrifugal filters are often used to separate suspensions containing larger solids and larger solids. When the dirty liquid to be purified enters the high-speed rotating separator, the solid particles are trapped in the wall of the separator due to the centrifugal force, and the clean liquid flows out from the upper side of the separator. […]

Filtration and classification of the filter In order to meet the different requirements of different separation objects, filtering methods and equipment are varied. To master the filtering technique, the filtering must be properly classified. (1) According to the mechanism of the process can be divided into filter cake filter and deep filter. Filter cake filtration. […]

As the name implies, multifilament fabrics are produced from yarns that have many individual continuous filaments. Multifilament yarns are referred to in their size as denier. Denier is the weight in kilograms of 9,000 meters of a multifilament yarn. Therefore, the larger the denier number, the larger the yarn, and it is a directly proportionate […]

These are characterized as having the best cake release, the highest flow rates, less likely to blind, and by comparison would have the poorest retention (filter efficiency). The yarns are measured in terms of mil diameter, for example, 6 mil diameter yarns, 8 mil diameter, 12 mil diameter, 15 mil diameter, etc. The larger the […]

Until the 1950’s and the advent of synthetic fibers, natural fibers such as cotton and wool were used almost exclusively in industrial liquid filtration. As synthetic fibers were developed and made readily available, they began to replace natural fibers and today are the primary fiber type used in liquid filtration. Nylon was the first important […]
