Water treatment chemicals are used as chemical agents in the treatment of industrial waste water and chemical waste water. After chemical reactions, water can reach a qualified level. At present, the amount of water used in various countries has increased sharply. In addition, the regulations for environmental protection requirements have been formulated. The development of pharmaceuticals is also increasingly valued.
Sterilization and disinfection: Water disinfection methods can be divided into chemical and physical. Physical disinfection methods include heating, ultraviolet, and ultrasonic methods; chemical methods include chlorination, ozone, heavy metal ion methods, and other oxidant methods.
Magnetization: The use of magnetic field effects on the treatment of water is called the magnetization of water.
Precision filtration technology: Jiangsu Dongchang Environmental Protection Technology stated that the microporous filter element and filter membrane made of special materials use its uniform pore size to trap particles and bacteria in water, so that it cannot be removed and retained through the filter element and filter . Precise filtration can filter micrometer (μm) or nanometer (nm) particles and bacteria. It is also widely used in the advanced treatment of water.
Ultrafiltration technology: Ultrafiltration is a membrane separation technology. That is, under a certain pressure (the pressure is 0.07-0.7Mpa, not more than 1.05Mpa), water flows on the membrane surface, water and dissolved salts and other electrolytes are tiny particles, which can penetrate the ultrafiltration membrane, and particles with large molecular weight And colloidal material is blocked by ultrafiltration membrane, so that some particles in water can be separated. The pore diameter of an ultrafiltration membrane is determined by a retention test using a substance of a certain molecular weight, and is expressed by a molecular weight value.
