CO2 for Aluminium Reduction

CO2 in aluminium reduction.

CO2 to reduce aluminium in purified water

The contribution of CO2 reduces the aluminium concentration of treated water in drinking water purification stations, guaranteeing values below the established limit and minimising costs associated with the coagulant dosage.

CO2 neutralises water, minimising the solubility of the aluminium, without the risk of acidification and maintaining the Langelier index in the adequate range.
