Sander FreshSkim Protein Skimmers
Sander fresh water protein skimmers have been developed especially for the treatment of pond water and are ideal for the Koi enthusiast. Sander FreshSkim Protein Skimmer provides you with crystal clear water, and protein compounds and turbidity are removed before they become harmful for the system.
Working principle of Sander’s protein skimmers
Sander’s skimmers use very fine air bubbles as the central filtration element. An active zone builds up on the bubble surface, to which protein compounds adhere very easily due to their molecular structure. These form two molecular ends – a hydrophobic moiety which attaches to the bubble surface, and a hydrophilic moiety which reaches into the surrounding body of water. Various pollutants, in turn, accumulate around the hydrophilic part – in particular, organic materials such as bacteria, viruses and other pollutant particles.
A conglomerate of air bubble, protein molecules and pollutants forms and floats to thewater surface due to the bubble’s buoyant force. The protein compounds’ surface activity causes a firm foam structure to build up, enclosing the pollutants. This foam is discharged via the foam tube.
In this way, pollutants are removed not only from the pond/aquarium, but completely from the water cycle. In this way, the protein skimmer opens a window in the cycle of materials. This fact distinguishes the protein skimmer substantially from any other mechanical filter.
Substances that may be removed from the water using protein skimming:
Sander protein skimmers are ideal reaction vessels for the application of ozone. All Sander protein skimmers are equipped with an ozone inlet. The use of ozone supports and enhances the efficiency of the skimming process and offers valuable benefits – including oxidation of nitrite, degermination and formation of stable foam.
Sander protein skimmers effectively enhance the cycle of gases in the water. Animals breathe oxygen and exhale carbon dioxide. This reduces the water’s pH. In the skimmer, carbon dioxide is largely blown out, and oxygen is re-introduced. The water from the skimmer’s outlet is constantly slightly oversaturated with oxygen.
