How To Choose Filter Cloth?

图片
The choice of  filter cloth  is very important for the filtration effect. The filter cloth plays a key role in the use of the filter press. Its performance is good or bad, and the correctness of the selection directly affects the filtering effect. The most common filter cloth currently used is a filter cloth made of synthetic fibers. According to the material, it can be divided into polyester, vinylon, polypropylene, nylon and so on. In order to achieve the interception effect and the filtration speed are ideal, in the selection of the filter cloth, it is also necessary to select according to the particle size, density, chemical composition and filtration process conditions of the slurry. Due to the difference in materials and methods of weaving, the strength, elongation, gas permeability and thickness of the filter cloth are different, which affects the filtering effect. In addition, the filter media also includes cotton woven fabrics, non-woven fabrics, screens, filter ...

Precautions for Using the Plate Frame Filter Press in Summer

图片
In summer, the temperature is high and the humidity is high. Many machines and equipment are overloaded due to overheating of the machine during operation, and the filter press is no exception. When using Plate and Frame Filter Press in summer, it is important to pay attention to the operating state of the plate and frame filter press to prevent damage caused by overload operation from affecting the filter press. So, what should you pay attention to during use?  Plate Frame Filter Press Factory  to explain to you. First, we pay attention to the hydraulic system. Since the equipment will repeatedly pressurize the filter plate during the working process, the hydraulic system will work frequently, withstand the huge pressure on the filter plate, the weather is hot, and the hydraulic device is easily overheated. Since the hydraulic unit itself is a highly enclosed component, some simple cooling methods are not ideal for hydraulic systems. Therefore, when using the Plate and Fra...

What is The Working Principle Of Filter Press

图片
A  Filter Press  is most commonly used to dewater sludge Made from industrial wastewater treatment plants. Filter Press Manufacturers  tell you the first stage of dewatering in a filter press is chemical conditioning. This is normally achieved by dosing a polymer into a mixed sludge storage tank upstream of the filter press. The flocculant will bind the sludge particles to larger flocs that are thicker and easier to dewater from the press. The slurry is then introduced through the center of the press where it fills the chambers between the plates. The pressure forces the liquid through the  Filter Cloth , whilst solids are retained between the plates. The filtrate flows between ridges in the plates to the corners where it discharges. The stages are as follows: 1. The chamber is empty, but has been sealed closed by the hydraulic ram. The press is ready to receive wet solids. 2. The wet solids are fed into the c...
