Shrimp culture: the application of ceramic membrane in aquaculture

Prawns are one of the most popular meats. They are not only high in protein and almost zero in fat, but also rich in calcium. However, in order to satisfy the appetite, it is not realistic to rely on the wild. Therefore, the shrimp on the market are basically cultured artificially.

Now it has become more and more difficult to raise shrimp. In addition to the high incidence of diseases, feed, climate and so on, water pollution is the major problem at present. As a result, the risk of aquaculture wastewater is increasing. In order to treat seawater on a large scale, it is necessary to select the process according to local conditions, and some farmers who have pursuit will choose Ultrafiltration equipment to complete this step.

The pore size of ultrafiltration membrane is 0.02um~1um. Its function lies in physical filtration of suspended solids, colloids, bait, bacteria and viruses. It can also finely filter fine colloidal particles and remove fungi. It can be used as an important link in the recycling treatment of mariculture water. Ultrafiltration membrane can be divided into organic polymer membrane and inorganic ceramic membrane. Although organic ultrafiltration membrane such as polysulfone and polyvinylidene fluoride hollow fiber has been studied more in marine aquaculture, inorganic ceramic membrane can also achieve very good results. Moreover, the flat ceramic membrane has the characteristics of corrosion resistance, high temperature resistance, good mechanical strength and is suitable for extreme water quality conditions. Therefore, compared with organic membrane, it will be more effective The floor is durable.
