Abstract/ Foreword

It proved experimentally that for neutralized sea water (removal of microorganisms) may be used electro dialysis device, as its economy and proper quality of sea water are justified. Research data need to refine and continue in this direction. At three locations in the Adjara coastal zone of the Black Sea (Pichvnari, Kvariati, the coast of the Batumi port), as a result of Electro dialysis, recorded more than effective ion removal NH4+ - ions, than NO2- -ions. As a result of electro dialysis, the concentration of both ions in seawater samples is below the maximum permissible concentration (MPC) norms, whereas in the initial samples, the content of these ions is was above the MPC norms. The total number of coliform bacteria is higher than the MPC (maximum permissible concentration) - in the coastal zone of the Batumi port (>11000). After passing through the electro dialysis device, no coliform bacteria were found, in none of the water samples taken from three locations. To neutralize sea water (removal of microorganisms) we recommend applying method of electro dialysis. Based on the large volume of sea water, it is uneconomical use a microfiltration process to clean it. In addition, in this case, complete membrane regeneration is required. Concerning, it is better to use sorption and membrane technologies directly in the vicinity of sources of pollution, and only after that release purified water in the sea.
