Description
  • This work deals with treatment of leachate from powerplant ash disposal site by the means of reverse osmosis. Examinated water contained high concentration of dissolved inorganic salts especially calcium sulphate. During separation, crystallization of concentrate would occur. This phenomenon is undesirable. Crystallization was delayed by addition of antiscalant, so it took place under controlled contiditions. Crystallization was also affected by presence of iron ions, whose concentration in leachate fluctuated. We proposed working conditions of separation process and we found the dependence of induction time of crystallization on iron ions concentration. Quality of produced permeate is sufficient to be used in powerplant as technological water.
