top quality cationic polyacrylamide matrix in Australia
Water suction was 0.34 g/cm 2 min for the test tubes with a 1 wt% of sludge and 0.41 g/cm 2 min when the content of sludge increased up to 15 wt%. Suction water affects quality and durability of the final material. High contents of sludge could cause defects in bricks, a clear tendency on water suction and, therefore, lower durability. Download
The aerobic treatment sewage sludge and sewage treatment sludge had the highest useful heating value (9.47 MJ kg−1), whereas pure drinking water treatment sludge had the lowest one (4.62 MJ kg
