Abstract

An experimental study was conducted with the aim of comparing different types of coagulants and choosing the most suitable type in (Geziret Al-Dahab) water treatment plant. Seven types of coagulants were applied, the first one was fer-rous sulfate FeSO4 the second was ferric sulfate Fe2 (SO4)3, the third was am-monium chloride, the fourth one was ferrous chloride Fe Cl2 the five was alu-minium sulfate (alum) Al2 (SO4)3, the sixth one was chitosan and the last one was alum with chitosan. the maximum removal efficiency of turbidity was real-ized by using alum with chitosan. The maximum removal efficiency was 82% at dose =5/15mg/l of initial concentration 1%. Furthermore, the minimum remov-al efficiency of turbidity was obtained when using chitosan as a coagulant.  was 56% at dose = 8 mg/l. There was no important effect on the values of entire dis-solved salts when using the above coagulants. There was an important effect on the conductivity of raw water when using chitosan.
