Recycling systems are used in addition to the ready mix concrete industry in the precast and concrete goods industry. In this case the requirements are different in comparison to the requirements in the ready mix plant. Lies the main focus on the recycling of the residual material in the ready mix concrete plant, so the focus is primarily in the precast and concrete goods industry in the field of treatment of excess wash water.
Excess water which can not be used directly in the mixing process is clarified here, so that clean water is available. This can be used in the production process or discharged after treatment into the canalisation.
The produced sludge during wastewater treatment process is also used as far as possible again in the mixing process to form a closed circuit. If the amount of produced sludge may be greater than the usable amount in the mixing process, so the system can be supplemented with a chamber filter press.
