Enhancing sludge dewatering and heavy metal removal by ...

2018-10-8  The sludge SRF decreased with an increase in sludge moisture content, i.e. the higher the moisture content of the sludge, the greater was the sludge dewatering efficiency. After 3 days of reaction, the pH decreased to 3.3, 2.7, 2.4, and 2.3 at sludge moisture contents of 95, 96, 97, and 98%, respectively ( Figure 3(b) ).
