WebThe amount of sludge produced during clarification can be reduced by 50-90%. The approximate dry weight of solids removed per pound of dry alum and ferric sulfate are approximately 0.25 and 0.5 lb, respectively. The resulting sludge contains less chemically bound water and can be more easily dewatered. WebThe neutralization flowsheet with this high pH feature is a high-density sludge (HDS) flowsheet. CO 2 Stripping. Excess CO 2 dissolved in the acid mine drainage stream can be stripped out using a surface aerator. Lowering the CO 2 levels can raise the pH as much as one point and lower the amount of lime required for pH adjustment. raymond tv https://chanartistry.com
