Traditional filter material, such as quartz sand or granulate is, due to its porous, unregular structure, highly sensible for fungi, bacteria, germs, algae as well as calcification. The contaminations and germs get stuck in the unregular parts of the highly porous surfaces of the filter material, multiply themselves in the water in an uncontrolled and unlimited way. Also during the backwashing, they are never eliminated.
LOEHRKE-Beads are glass pearls of high quality which may be used as alternative for gravel. Thanks to the exchange, clearly longer cycles between the required backwashing steps are possible. Due to the smooth surfaces of the glass pearls and their CIP-capacity, clear hygienical improvements are realised that are advantageous for the product quality, also reducing the use of disinfecting products.
