The turbidity denotes the concentration of colioids. Alkalinity is used for restoring pH after alum (coagulant) addition.
In the case of low turbidity small number of colloids make the coagulation difficult. If the alkalinity is high, moderate alum doses will result in the formation of AI(OH)3 which is amorphous and gelatinous. So sweep coagulation takes place. High turbidity-low alkalinity: With relatively small doses of coagulant, water can be coagulated by adsorption and charge neutralization. Depression of pH makes this method more effective because aquometallic ions are more effective at low pH.
High turbidity-high alkalinity: The pH will be relatively unaffected by coagulant addition. Because of high alkalinity, adsorption and charge neutralization will be less effective than in waters of low alkalinity. Higher coagulant dosage should be used to ensure sweep coagulation.
