Filter construction FRESHWATER SKIMMER Our freshwater skimmers produce foam like a seawater skimmer!   The energy demand is very low, because we only need a pump that pumps high volume but small static head.      The skimmers combine three different filter-systems: biological, mechanical and chemical. The skimmer-principle is since many years  standard for seawater-systems. Our special construction allows now to skim proteins out of freshwater-systems as well.   Function:   An underpressure in front of the pump mixes air into the water. In this way a overpressure is generated in the upper part where the water flows  over our biological trickling filter material. A special milled the foam of the water and lead it out through the cap. The surface tension of the air-  bubbles attracts and concentrates dissolved particles like dirt, chemicals, dyes or algae, which results in the foam.   Benefits: - stabilization of pH - removes dyes, dissolved particles, proteins, etc. - rises oxygen level in the water - works directly and is not addicted to any bacteria - prevents diseases caused by bad water quality - increased effect by ozone   Technical Data (Subject to change!)
