Sludge composting| Composting from sewage sludge | Dispose
Sludge Composting. According to statistics there are nearly 600 sewage treatment plants in China at present. And the sludge generated during the sewage treatment process is about 0.3-0.5% of the sewage treatment capacity. If we calculate based on this data, China’s municipal sewage treatment plants discharge is about 1.4 x 10t/a of dry sludge.
