Sludge from wastewater treatment processes are treated and then disposed or reused in crop production or other applications. age per capita usage from public water supply systems in the united states was 184 gallons 700 liters per day solley et al., 1993. in arid areas, municipal wastewater production is typically less than the.
Sludge dewatering. the improved sludge dewatering effectiveness was obtained using the energy of ultrasounds of 800 and 2200kjkg d.m. an insignificant reduction in the size of sludge flocs andmall increase in the concentration of extracellular polymeric substances zhang et al., 2007 can explain the observed improvement in sludge dewatering capacity.
