Recycling water is produced when washing out green concrete in ready mixed plants and prefabrication plants. Due to ist contents of cement the water is strongly basic (pH ~12). In case the recycling water can not be reused completely in production, it has to be clarified (separation of solids from the water). The clarified water can be reused for cleaning purposes or for example for the washing out of prefabricated elements. According to the regulations of the labour safety or due to specific on site conditions in the factory (for example: avoiding of colour shadows on washed out elements) it might become necessary to neutralize the clarified water. This can be achieved by using Carbondioxide (CO2 ). Because of the special buffer system CO2 developes with water a false dosing is nearly impossible. When using Carbondioxide no destructive substances are introduced into the clarified water.
