Artificial sea salt, also known as seawater element, can not be eaten directly, and can only be eaten after a series of processing into salt.
Seawater element is a seawater element that can keep the original composition of seawater. Its production process adopts an independent single seawater drying pool. Without any process, each pond is not mixed, segmented, salted or drained, and seawater elements are obtained by drying until they are completely dry. Therefore, seawater with the same composition as natural seawater can be obtained after remanufacturing without losing the original composition of seawater, which can be used for urban seafood culture, seawater bathing and various industrial purposes.
Seawater can keep the original components of seawater, which is characterized in that the production process adopts one-time drying from seawater to dry seawater to produce seawater that can keep the original components and various substances contained in seawater.
According to the chemical composition of natural seawater, fresh water is made up of dozens of pure inorganic salt raw materials in scientific proportion, and contains a large number of trace elements in natural seawater. It is the best choice to breed all kinds of marine fish, shrimp, shellfish and software instead of natural seawater.
In recent years, the pollution of coastal waters is serious, the natural reproduction rate of seawater in many coastal areas is not high, and fish die in a large area, which is mainly caused by the pollution of coastal waters. The artificial seawater is pollution-free and safe, meets the requirements of pollution-free aquaculture water, and can be specially adjusted according to the local groundwater, which is suitable for marine biological culture with local water quality. The operation is simple, and artificial seawater can be made by adding a certain amount of seawater according to the fresh water quantity.
Extended data:
(1) Because the raw materials for preparing artificial seawater include calcium salt, magnesium salt, potassium salt, sodium salt and sulfate. These salts react chemically when they are mixed. For example, calcium easily reacts with sulfate to produce calcium sulfate precipitate, which will affect the composition of seawater. Therefore, in order to prepare stable soluble inorganic salts according to the characteristics of these salts, it is necessary to strictly control the processing procedures of these raw materials to prevent the precipitation of CaSO4, CaCO3 and Mg(OH)2, thus improving the quality and grade of artificial seawater.
(2) Natural seawater contains many trace elements and nutrient elements, many of which are minerals transported to the ocean by weathering products of terrestrial rocks through the atmosphere, rain and rivers, and some of these minerals are indispensable for the growth and reproduction of marine life. For example, iron usually exists in the form of Fe2+ and Fe3+ in seawater. The presence of iron makes the colors of marine life brighter. It is not only an important catalyst for biodegradation in seawater aquarium, but also a nutrient salt needed by unicellular algae.
We can't simply add substances containing these trace elements directly into seawater, which will affect the transparency and composition of seawater. Therefore, based on the law that trace elements come from rock weathering, we extract these trace elements from natural substances such as shells, medical stones and volcanic ash, and make these elements exist in the form of various ions or ion pairs in artificial seawater, so that artificial seawater is closer to natural seawater.
(3) Keep the pH value of artificial seawater at the optimal value of 8. 2 ~ 8.4. Because the pH value of seawater is 8. Two and eight. It is most suitable for the growth of marine life, and it needs to adopt a unique treatment method, adding CO2, HCO3 and CO2 to prevent the formation of sediments, keep the pH value stable and prevent the pH value from decreasing. So as to obtain the best pH value suitable for marine life, and at the same time control the KH value between 7 dkh ~ 10 dkh.
