In the early days, most filtration processes relied on gravity filtration. Later, pressure filtration was introduced to increase filtration speed, followed by the development of vacuum filtration. Do you know how the operational performance of gravity filtration has evolved over time?
Filtration technology has been used in China for a long time. In fact, filtration was applied in production processes long before modern industry. For example, filtration techniques were already used in ancient Chinese papermaking. The history of filtration is therefore very long. The earliest filtration method was gravity filtration. Ancient people in China made good use of gravity filtration with their ingenuity. Today, filter machines are widely used, but to achieve higher filtration efficiency, continuous improvements are still required. To enhance the operability and efficiency of gravity filtration, it is necessary to understand both pressure filtration and gravity filtration so that filtration operations can gradually become more continuous.
Today, the available filtration area is becoming larger and larger, and there are more types of filter machines being used. By separating the filtration medium from the container, filter cake is formed under pressure, although the filtration process may still require a relatively long time. Liquid filtration is now widely applied, and the filtration process must overcome the resistance formed by the filter cake layer. In terms of filtration speed, improving continuous filtration operations has become an important direction for the automation development of modern filter machines. Under conditions of lower moisture content, the application of filter machines has gained more and better opportunities for development.
