1. Undercurrent two-way washing: wash the washing liquid twice from the two washing liquid inlet holes on both sides above the stop plate, that is, the washing liquid washes first from one side and then from the other side. The washing liquid outlet is diagonal, so it is also called undercurrent two-way alternating washing.

2. Non blocking one-way washing: the washing liquid enters from the washing liquid inlet hole of the thrust plate in sequence, passes through the filter cloth, then passes through the filter cake, and flows out of the non porous filter plate. At this moment, the outlet nozzle of the perforated plate is closed, while the outlet nozzle of the non perforated plate is open.

3. Open flow two-way washing: wash the washing liquid twice from the washing liquid inlet holes on both sides above the thrust plate, that is, wash the washing liquid first from one side and then from the other side. The washing liquid outlet is diagonal, so it is also called two-way interleaved washing.

4. the underflow unidirectional polyester is the emulsion entering the perforated plate from the emulsion inlet hole of the thrust plate, passing through the filter cloth and passing through the filter cloth, and flows out of the non perforated filter plate.

5. Countercurrent scouring: in order to improve the cleaning power, the filter cloth of the filter press is often washed by countercurrent scouring. If the dividend is divided into three sections, we use fresh washing liquid in the third section, and then the effluent can be used as the washing liquid in the second section, then the effluent can be used as the washing liquid in the top section, and then the effluent can be used as the mother liquor.
