Neutralizing the pH of filtered water by adding acid or CO2 from fresh concrete recycling, as proposed by HYDROSTOP, is an essential step in the process of treating wastewater generated by concrete production. The aim of this phase is to adjust the pH of the filtered water to bring it into line with environmental standards and regulatory requirements before releasing it into the environment.
Filtered water from the fresh concrete recycling process may contain high pH levels due to the chemical reactions involved in concrete manufacturing and recycling. High pH levels can be detrimental to the environment if discharged untreated.
To neutralize the pH of filtered water, HYDROSTOP proposes the use of acid or carbon dioxide (CO2), also derived from the fresh concrete recycling process. These substances are added to the filtered water in a controlled manner to lower its pH to a safe and acceptable level.
The acid or CO2 reacts with the alkaline compounds present in the filtered water, reducing its pH and making it more neutral. This neutralization process is closely monitored to ensure that the pH of the water reaches the level required for safe discharge into the environment.
Once the pH has been adjusted, the treated filtered water can be released into drainage systems or watercourses, in compliance with current environmental regulations.
In short, HYDROSTOP’s pH neutralization of filtered water with acid or CO2 from fresh concrete recycling ensures that wastewater from concrete production is treated responsibly before discharge into the environment, helping to preserve water quality and the sustainability of the concrete industry.
