Working principle of protein skimmer

Compared with traditional aquaculture, the recirculating aquaculture system is less affected by natural conditions (such as red tides and turbid water caused by weather),This is especially true and has low operating costs (especially when the water intake point and the elevation of the aquaculture structure differ greatly and the heating period in winter) This is especially true) and has received increasing attention. In the production of circulating aquaculture, the number of times the aquaculture water circulates in the system increases, which affects the normal growth of the aquaculture objects. The advantages of the circulating water system are unquestionable, but it does have certain problems, one of which is that there is no perfect facility to remove organic matter in the system.
The main sources of organic matter in the circulating water aquaculture system: one is the organic matter produced by the dissolution of the residual bait in the water, and the other is the metabolites discharged by the breeding object and other organic matter produced by the above-mentioned organic matter under the action of microorganisms such as bacteria. Organic matter is an important source of nutrients for bacteria and other microorganisms. Under aerobic conditions, bacteria multiply to reduce dissolved oxygen (DO) in water. Therefore, reducing the organic content in water is an important measure to stabilize water quality.
Protein separator is a process in which gas is introduced into the water to form bubbles, and surface active substances or hydrophobic micro-suspended substances in the water are adsorbed on the bubbles and float to the upper part of the separator to form a foam layer to separate them. Organic matter in water like protein has an amphiphilic structure and is easily adsorbed on bubbles, so it can be separated.
