A certain quantity of sludge supernate taken after dewatering was used for the detection of zeta potential to evaluate the charge neutralization effect of the resulting polymers with analogous molecular weight and various contents of cationic monomer. The electrophoretic mobility of these samples was ...
The groundwater ages, determined using the tritium detection method, were important to understand the recharge of the individual aquifers. As there is no direct recharge at the surface, the aquifers are only recharged by the slow leakage of groundwater from the upper to the lower aquifers. The...
In our case, in a process carried out at a similar temperature level, the production efficiency of biochar from sewage sludge was higher, at approximately 56%. The observed trend is consistent with the results presented by other researchers [16,40,41,42,43]. Table 3. Biochar production ...
