Most of the earliest filtration was gravity filtration, later on, pressurized filtration was used to increase the filtration speed, and then vacuum filtration was introduced, and the invention of rotary drum vacuum filter at the beginning of the 20th century enabled continuous filtration. Since then, various types of continuous filters have appeared. Intermittently operated filters (plate and frame filter presses) were developed for automated operation, and the filtration area became larger and larger. To obtain a low moisture content of the filter residue, the Air Shower was developed as a mechanical press. Next, let's look at the principles of Air Shower selection. Here are some answers.
