Abstract
The raw water treatment using coagulant and ultrasound indicates a faster decrease of turbidity. The main water indicators - pH dynamics and dissolved oxygen content are also presented and discussed. The dose of aluminum sulphate, actually the most widely used coagulant, decreases 8 times at the use of ultrasound waves, which represents an economy of chemicals for the water plants.
