What are the applications of potassium persulfate tablets in aquaculture

Now many aquaculture workers are using potassium persulfate tablets, which can effectively adjust water, improve the bottom or control algae, etc. The potassium persulfate tablets sold on the market are often not pure, but are acidic complex salts composed of many raw materials. Potassium persulfate tablets can directly disinfect toxic substances in the water. So what are the applications of potassium persulfate tablets in aquaculture?

First, what are the applications of potassium persulfate tablets in aquaculture? What we call potassium persulfate is actually just an abbreviation. The full name is potassium monopersulfate or potassium monopersulfate, with the chemical formula KHSO5. The products sold on the market are generally not pure potassium persulfate, but an acidic complex salt composed of three raw materials: potassium permonosulfate, potassium sulfate (KHSO4), and potassium sulfate (K2SO4). The active oxidizing substance is potassium permonosulfate, and its content ranges from 5% to 50%. It comes in powder, flake, columnar, irregular granular and other forms. The content of powder is much higher than other forms. The content of products used for bottom modification is generally around 10%. Of course, the higher the potassium persulfate content is not necessarily better. As far as bottom improvement products are concerned, tablets have more advantages than powders. They act directly on the bottom of the pond, avoiding loss and waste in the water body, and can produce higher local concentrations.

Second, as we all know, in addition to biological bottom modification, the most commonly used bottom modification products are oxidants. Currently, oxidants used in aquaculture can be roughly divided into three categories: chlorine preparations (such as chlorine dioxide, bromine chlorine, hydantoin), peroxides (such as potassium persulfate, calcium peroxide), and ferrates (such as potassium ferrate, sodium ferrate). Most oxidants are advertised as having two functions: "sterilization" and "detoxification". We use three representative oxidants: chlorine dioxide, potassium persulfate, and potassium ferrate to compare these two functions.

What are the applications of potassium persulfate tablets in aquaculture? The mechanism of action of potassium persulfate is mainly to utilize its strong oxidizing property to react with water to generate unstable ozone. Ozone instantly decomposes to generate oxygen (O2) and atomic oxygen (O), the so-called new ecological oxygen. Atomic oxygen has very high energy and plays a role in killing and inhibiting bacteria and viruses. The reaction process does not produce any harmful substances, and the generated oxygen can also play an oxygenation role. It is green and safe and is widely used as a water treatment agent.
