KLÄRFIX® process water treatment

Many concrete and stone processing facilities constantly generate excess and waste quantities of concrete as well as rinsing water containing solid matter and active cement content. The waste process water can be recirculated in order to minimise costs for fresh water and waste water disposal. The solid matter contained in this water can be easily recovered and returned to the material flow if the water is immediately treated.

Process water recycling systems from hoelschertechnic-gorator® are built using components that are manufactured in-house and clean the waste water produced based upon the type of contamination and desired form of reuse. You determine the quality of water you need and we use our module system and the KLÄRFIX® formula to determine the technology required!


Use our KLÄRFIX® formula to solve your process water problems!
