Filtration method: In the initial stage of filtration, the filter media can only intercept large solid particles, and small Filtration method: In the initial stage of filtration, the filter media can only intercept large solid particles, and small particles pass through the filter media with the filtrate. After the formation of the initial filter slag layer, the filter slag layer plays a major role in the filtration. At this time, large and small particles are intercepted, such as the filter of plate and frame press.
