5T Foam Fractionator

Protein Skimmer

Product Description

CAT brand protein skimmers use very fine air bubbles asthe central filtration element. An active zone builds up on the bubble surface, to which protein compounds adhere very easily due to theirmolecular structure. These form two molecular ends – ahydrophobic moiety which attaches to the bubble surface, and a hydrophilicmoiety 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 particles and other pollutant.

A conglomerate of air bubble, protein molecules and pollutants forms and floats to the water surfacedue 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 aquarium, but completely from the water cycle.

The protein skimmer opens a window in the cycle of materials. This fact distinguishes the protein skimmer substantially from any other mechanical filter.

Substancesthat may be removed from the water using protein skimming:

· Protein compounds

· Various organic compounds

· Reduction of bod and cod (biological and chemical oxygen demand)–cod in the foam is concentrated by a factor of about100

· Precursors of the toxins, ammonium and nitrite

· Fine suspended solids

· Residual feed and feces

· Bacterial biomassand microalgae

· metabolic productsfrom the biofilter

CAT protein skimmer sare ideal reaction vessels for the application of ozone. All CAT protein skimmer sare equipped with an ozone inlet. The use of ozone supports and enhances the effiency of the skimming process and offers valuable benefits– including oxidation of nitrite, degermination and formationof stable foam.

Gas balance

CAT protein skimmers effectively enhancethe cycle of gases in the water. Animals breathe oxygen and exhale carbon dioxide. This reduces the water’s pH. In the skimmer, carbondioxide is largely blown out, and oxygen isre-introduced. The water from the skimmer’s outlet is constantly slightly oversaturated with oxygen.
