| Abstract | ||
| This research focuses on the use of hydrate and dehydrate aluminum sulfate (Alum) ,ferrous sulfate and ferric chloride ,Which burnt in different temperatures degrees ,or use U.S.Pat.NO.4105747 to dehydrate of ferric chloride, and compare the result and selected the batter coagulate to remove the turbidity from the water sampling light 6NTU ,medium 55NTU ,high 150NTU turbidity use the jar test to find the change in PH and turbidity at the same condition . The study revealed the efficiency of the gradually dehydrate coagulant in reducing the turbidity from prepared samples by continuous burnt when using alum and ferrous sulfate, and when use ferric chloride in continues change from hydrate to dehydrate coagulant. The hydrate and dehydrate alum is batter coagulant for removal turbidity. The final turbidity from the light sample less than 1NTU and less than 2NTU from the medium samples, less than 3NTU from high samples. There is no change in the cost by using hydrate or dehydrate alum. It appears high increase of removal ratio between hydrate and dehydrate alum i.e from 64% to 85% for light samples and from 94% to 98% for medium samples, 91% to 98% increasing removing ratio from high turbidity samples. | ||
