  • Can polyaluminium chloride improve coagulation process in conventional water treatment?
  • The coagulation process in conventional water treatment could be enhanced and the ensuing water pH decline reduced appreciably by applying the right dosage of polyaluminium chloride and appropriate process conditions of pH, fluid mixing speed matrix and residence time.
  • Is polyaluminium chloride better than polyelectrolyte – alum-based coagulation?
  • At the Barekese Water Treatment Plant in Ghana, an alternative, the polyelectrolyte – polyaluminium chloride (PAC) is also used in coagulation but limited information is available on the operating conditions required to achieve better performance than alum-based coagulation.
  • What are the advantages of polyaluminium chloride and aluminium chlorohydrate coagulants?
  • 2. Literature review Use of Polyaluminium chloride and Aluminium chlorohydrate coagulants give significant advantages over alum, including reduced chemical costs, lower residual aluminium levels, improved treated water quality including lower TDS and sulphate levels and lower sludge production .
  • Which coagulant has the lowest cost?
  • Namely, coagulant PACl + FeCl 3 shows the lowest cost and the highest efficiency during its use in the drinking water treatment plant under study. The cost-benefit ratio of coagulant PACl + FeCl 3 is 1.19 times lower compared to the coagulant PACl. Content may be subject to copyright. [...]
