Abstract:
Objective To assess the sanitary quality of finished water produced by seawater desalination plant.Methods Using reverse osmosis for seawater desalination,the microbiological indexes,the levels of chloride and the pH values of finished water after seawater desalination were determined and then were assessed based on the National Method for Determination of Drinking Water(GB 5750-1985).Results After seawater desalination,the level of fluoride in finished water was 426 mg/L,the total count of bacteria of 3 finished water samples among 9 samples exceeded the standedard(350,300,4016/L),the pH valuer were qualified on the whole,except one lower value of 5.74 and a higher value of 8.94.Conclusicn After the treatment by seawater desalination system,the level of residual chloride in finished water was higher which approached the related highest limit ruled by National Sanitary Standard for Drinking Water,the microbiological indexes and pH values of finished water were unstable.
