Why is the water content of the snail stacking machine high?

The high water content of the snail stacking machine is a headache for many users. Today, Hangzhou Co., Ltd. will show you:

1. The quality of sludge is complex, the content of organic matter is extremely high, and the sludge particles are too hydrophilic.
2. The conditioning of sludge is not successful, and the conditioning is not carried out according to the quality of sludge, which destroys the hydrophilicity of sludge.
3. The pressure of the sludge dewatering equipment is too low and the degree of squeezing of the sludge is not enough, which is also the main reason. For example, the water content of the sludge treated by ordinary plate and frame filter presses, belt filter presses, and chamber filter presses is relatively high, while the water content of sludge treated by diaphragm filter presses with secondary pressing function is slightly lower. The new ultra-high pressure sludge filter press has a squeezing force 4-6 times higher than that of the ordinary sludge filter press, and the water content of the sludge after dewatering is low and the dewatering is thorough.

Fourth, the large amount of organic matter in the water increases, which leads to the increase in the hydrophilicity of the mud. The organic matter content has a great influence on the moisture content of the mud cake. The moisture content of the mud cake of mechanically purified water will be about 50%. When it becomes water containing a lot of organic matter, the moisture content of the mud cake will drop to 100%. Of seventy-five. The solidification of the mud has a small moisture content between 50-60%, so no matter how you adjust it, the dehydrated mud cake cannot be solidified.
