Features in more detail:
Hardness control:
- Thanks to the pH increasing properties and the calcium source, an appropriate decarbonization or remineralization of the water is achieved.
pH control:
- The AquaCalco® product range (Q, S, M) with a pH value of 12.6 has a high neutralization value, which allows a suitable and correct pH increase.
- The AquaCalco® LS acts as a natural buffer as it slowly reacts with acidic water and neutralizes it up to a pH of around 7, while mineralizing the water with calcium and/or magnesium.
Precipitation of inorganic pollutants:
- Thanks to the increase of the pH value heavy metals can be efficiently removed from the wastewater.
- Due to the calcium content of the AquaCalco® range, pollutants such as sulphates, phosphates and fluorides are precipitated as low-soluble calcium salts.
COD reduction by coagulation:
- The AquaCalco® products promote the coagulation/flocculation of insoluble organic matter in water. By removing these organic components in the form of sludge, a significant reduction in COD (chemical oxygen demand) can be observed.
Availability:
- Most of the AquaCalco® products are produced locally.
Benefits in more detail:
Upcycling of softening by-products:
- The decarbonization process with AquaCalco® products forms a limestone sludge that can be valorized e.g. in agricultural processes.
Safe and easy to handle:
- The AquaCalco® S and M are considered as non-ADR product and non-corrosive to the skin.
Unique pH neutralization:
- One on one replacement of Caustic Soda.
TCO reduction:
- AquaCalco® is more cost efficient than other pH increasing neutralizing agents.
- AquaCalco® improves coagulation while reducing the need for other chemical reagents in physicochemical water treatment.
- Reduced wear and cleaning needs due to hardness control.
- No limitation of availability and is produced locally.
Dedicated solutions for your specific needs
![municipal-wastewater](/sites/default/files/2023-10/munic_waste_treatment_0.png)
In many industries, large quantities of water are required. The source of water is surface water, groundwater, or recycled wastewater. In any case, these waters often have to be pre-treated before being used in the required process.
Depending on the final utilization of the water, Carmeuse offers the AquaCalco® product range to address specific quality and cost optimization requirements for process water. The product range consists of a wide range of dry products (AquaCalco® Q, S), which in many cases require the preparation of a suspension on the side, and ready-to-use suspensions (AquaCalco® M) with different chemical compositions and concentrations.
For the application in process water linked to water treatment processing for food contact application, our AquaCalco® W range is compliant and certified to EN-12518:2014.
Main customer application where AquaCalco® is used in wastewater:
- Chemical industry
- Metal treatment industry
- Latex industry
- Food processing industry
- Energy production plants
