CLR-S has been developed to contribute to sustainable concrete production and to create “Green Santals” by fully reusing the recycling water in concrete plants. CLR system; It allows 100% use of the recycling water by measuring the pollution rate and density of the recycling water in real time, and prepares the dirty water – clean water mixture with the density specified in TS-EN 1008, which describes the quality of the water used in concrete recycling.
