Abstract
Pretreatment of wastewater with mineral coagulant of ferric oxide is investigated experimentally in this work. Nonvolatile suspended solids and volatile suspended solids beside other important parameters, total hardness, calcium hardness, CO2 content, Total dissolved solids, electrical conductivity, sedimentation time, chemical oxygen demands, biochemical oxygen demands, pH value after sedimentation and pH after coagulation in aerobic treatment are surveyed due to the changes in fast mixing rate.
