Abstraction and treatment with blower aeration
The raw water is pumped into the clarifier where chemicals are added according to intake from the boreholes. The chemicals are then mixed with this groundwater. The aeration is carried out with a diffused air sub-surface blower system where the air consumption is controlled according to the intake. Sub-surface aeration with a blower is one of the most efficient ways to aerate water and the biggest advantage is the possibility to control the amount of aeration according to the water quality.
