Diaphragm-type plate and frame filter press for paper mill residual sludge dewatering treatment
2023/02/17 718
Most of the paper industry adopts the form of incineration to deal with sludge, the burning calorific value of sludge incineration and its moisture content of the correlation is very large, absolute dry solid sludge has a high burning calorific value, the higher the moisture content of the sludge the lower the burning calorific value. Therefore, the deep dewatering of sludge and the reduction of sludge water content are important links in sludge treatment ....

Plate and frame diaphragm chamber filter press operation process common problems and treatment
2024/07/29 645
In the coal gasification industry, the gasification filter cake is usually blended into the power coal for blending and use, but because of the high water content of the filter cake, direct blending will cause power coal plugging. In order to reduce the risk of power coal blending and plugging, it is necessary to further reduce the water content of the filter cake. Plate and frame filter press can reduce the water content of filter cake very well, so to ensure that the plate...
