- the simultaneous jet cleaning step may be omitted depending on the dirt state of the filter cloth 8 (for example, the vicinity of the liquid supply plate 24), and the entire surface of the filter cloth 8 can be washed in the one jet cleaning step and the other jet cleaning step.
- the filter cloth cleaning method for the filter press according to the embodiment can be applied to a filter press in which a pair of cleaning nozzles are provided above the filter cloth and the cleaning nozzles are directed diagonally to the filter cloth. Since the entire filter cloth is efficiently washed, the amount of washing water can be reduced and the washing time can be shortened.
- the filter press can be used not only for dewatering tap water and industrial water sludge, but also for production processes such as chemical plants.
