Excellent results have been obtained in preventing attack on mild steel by
solutions containing upto 1 , 500 ppm chloride ion by adding polyphosphate at a
concentration of 50 ppm ( as P , Os ) and calcium or zinc at a concentration of 30
ppm .

Chlorination which is carried out to prevent algae growth may increase corrosion
if the concentration rises about 0 . 4 ppm . Concentration by evaporation may
increase the original chloride and sulphate content to a level as high as 10 times
