—— DEHYDRATION, ELECTRODIALYSIS AND HEAT DRYING ARE INTEGRATED INTO ONE
Small footprint
high degree of automation
Low operating cost
24 hours after-sales service
The thickness of the mud cake is 15-20mm, and the electrode and filter cloth will not be penetrated by the residual metal in the sludge.
Lower power consumption during drying
Integration of dehydration and drying equipment
Airbag sealing, good sealing effect, no mud leakage
The plastic filter plate is light in weight and corrosion resistant
Can be directly dried from 99% moisture content to about 50%
Only need to add a small amount of PAM or coagulant
The comprehensive operating cost is low, and the drying cost is 70-100 yuan per ton
The process area is small and investment is saved.
The electrodialysis plate and frame dehydrator is developed on the basis of the traditional dry diaphragm plate and frame dehydrator, that is, positive and negative electrode plates are installed on the filter plate of the plate and frame dehydrator to rectify the 380V alternating current of industrial electricity into direct current; voltage 75 -85V, current 2000-15000A. The operating principle of the process is a combination of the traditional high-drying diaphragm frame dehydration, electrodialysis dehydration, electroosmosis and Brownian motion.
(-) charged sludge extrusion
The combination of the (+) charge and the surface water to the (-) pole remove the water
The moisture accumulated on the (-) pole is removed by mechanical extrusion
