Treatment of process water in the concrete industry
Save money and resources by treating your process water
In many concrete or stone processing plants, residual and returned concrete as well as rinsing water with solids or cement components are constantly produced during the manufacturing process. The process waste water can be used for recirculation in order to minimise costs for fresh water and waste water disposal. The solids contained can also be easily returned to the material flow with immediate treatment.
With the modular system based on the KLÄRFIX® formula from hoelschertechnic-gorator®, you are able to bring your process water to the desired level of purity.

How to transform process water into service water
With the KLÄRFIX® modular system, you can determine the degree of purity of the treated process water yourself, step by step.
The wash-out screw removes solids larger than 0.2 mm from the process water. The pre-cleaned water is then fed into the residual water tank.
In the cone of the following clarification tower, any remaining fine particles settle by means of flocculant addition. The purified water rises to the top and is drawn off via a clear water channel.
In “sludge recycling ” , special filter presses ensure very high levels of dewatering of the sludge that is not reused in the process. This is ejected as a solid and the water obtained is returned to the process water stream.
In the “ pH neutralization ” the pH value of the purified water can be reduced as desired by means of CO2 gassing, if necessary.
