Protein Skimmer

Working principle

The contact surface of the protein skimmer, similar to the surface between air and water. The contact surface formed by the water surface of the aquarium has a certain surface tension, so cellulose, protein and food residues will inevitably accumulate here. In fact, if the surface area is enlarged, such as by creating air bubbles, more cellulose, protein and food residues will naturally form on the surface. The viscosity of the foam will change as the surface strengthens and expands and the bubbles gradually disappear. Therefore, the effectiveness of the protein skimmer lies in expanding the surface area between the gas and the liquid and its specific surface tension. However, the foam produced is separate from the discharge of the water cycle in the aquarium, which is why the foam can be removed directly from the aquarium.

Structure

The protein skimmer is composed of a contact chamber, an aeration device, a sewage collection chamber, water intake and drainage, sewage discharge, ozone filling, liquid level adjustment, flushing device and other parts.

Classification

The working principle of protein skimmer is very simple, but it can effectively use the surface tension of bubbles to separate proteins in water. There are three kinds of protein skimmer: counter-flow, pressure and gas lift. In theory, the protein skimmer can separate 80% of the protein in the water, but her actual working ability can only separate 30-50% of the protein waste in the water, and it is very good to be able to reach 50%. To put it simply, the working principle of the skimmer is that the tension of the bubbles pushes the dirt out and separates it from the water. At this time, the dirt and water are separated, and the concentration of no2 in the water is low, and the concentration of no3 is also low. The protein separated from the skimmer is stored in a collection tank in a liquid-like form and then cleaned up periodically.

Features

It can separate organic matter before it decomposes into toxic waste, reducing the burden on the biochemical system; increasing the amount of dissolved oxygen in the water. The disadvantage is that it will oxidize trace elements in water, such as iron, molybdenum, manganese and other important trace elements.
