The role of sludge drying equipment in sewage treatment

1. Sludge reduction and transportation cost control
Sludge drying equipment can reduce the moisture content from 80%-97% to 10%-50% by combining mechanical dehydration (such as centrifuge, plate and frame filter press) with thermal drying technology. Dehydration and drying treatment reduces the sludge volume to 1.1%-1.7% of wet sludge, with a reduction rate of 98%, greatly reducing transportation and landfill costs.

2. Resource utilization and energy recovery
After drying, the calorific value of sludge is increased, and it can be used as an incineration fuel to replace coal, achieve energy closure, and reduce external energy consumption. Low-temperature drying technology can also convert sludge into cement kiln alternative fuel to achieve industrial synergy.

3. Environmental protection and control of harmful substances
Sludge drying equipment can avoid odor overflow and reduce the risk of water pollution through condensate treatment (standard discharge). The drying process combined with chemical conditioning can solidify heavy metals in sludge, inhibit microbial activity, and reduce environmental risks.
