HAURATON has a safe and effective solution for the filtration and retention of microplastic particles: In the drainage and filter system SPORTFIX CLEAN the filter substrate Carbotec 60 reliably retains particles as small as 0.45 µm (0.00045mm). SPORTFIX CLEAN is an important measure to help prevent microplastics entering waters and oceans. With a rule-compliant dimensioning, retention capacities of over 90 % are achieved.
