Application of protein skimmer in factory aquaculture

A protein skimmer, also known as a protein skimmer, protein demister, protein remover, or foam separator, is a simple and effective wastewater treatment device used to remove large colloids from water. It primarily utilizes the surface tension adsorption of bubbles to concentrate and separate organic matter. Through flotation, it removes suspended colloids, cellulose, protein, leftover bait, feces, and other organic matter from aquaculture wastewater. In marine aquaculture systems, protein skimmers are an indispensable component of the circulation system.

The core of a protein skimmer is gas-liquid mixing. Traditional protein skimmers primarily use bicho tubes, which have low gas-liquid mixing efficiency and are prone to clogging, making them suitable only for marine aquaculture. Induced Air Flotation (THK), a new mechanical air flotation technology invented by Hydro Cal Environmental in the United States in 1985, produces more than 10 times the number of bubbles as bicho tubes. It can be used not only in marine aquaculture but also in freshwater aquaculture.

The high-efficiency protein separator adopts THK technology, which can quickly remove macromolecular colloids such as proteins, sugars, lipids, etc. in aquaculture circulating water. When used with heavy metal scavengers, it can effectively remove heavy metals in water bodies; when used with ozone generators, it can achieve a disinfection effect; when used with flocculants, it can remove various suspended solids and organic matter in freshwater aquaculture water bodies.
