The principle of surfactant sterilization is mainly to achieve the effect of sterilization by destroying the cell membrane structure and interference of its metabolic function. The specific principles are as follows: 1. Destroy bacterial cell membrane: Surface active agents have both the characteristics of hydrophobic and hydrophilic. Its molecular structure also contains hydrophobic groups and…
Surface active agent is a chemical that can reduce liquid surface tension. They are composed of a hydrophilic (like water) head and a hydrophobic (do not like water) tail. During the pollution process, the hydrophobic tail of the surfactant will be adsorbed to the surface of dirt, while the hydrophilic head interacts with water molecules….

The principle of the function of flocculant is to condense the properties of the material in the solution, so that the tiny particles that suspend the solution in the solution are concentrated into large blocks, which is convenient for precipitation or filtering. Flocculants are usually polymer compounds. They have polar groups or contain a large…
The precipitant and flocculant are used for chemical agents during water treatment, which are used to remove suspended particulate matter and turbid substances. Their mechanisms and methods of use are slightly different. 1. Mechanism: -Setal: The precipitant reacts the chemical reaction with the suspended particulate matter, forming a large sediment, so that the suspended objects…

Surface active agent is a type of compound with a certain solubility and interface activity. It can reduce the tension of liquid surface in the solution and form a layer of film on the liquid-liquid or liquid-solid interface. performance. According to the chemical structure and solubility of the surfactant, it can be divided into two…
The four major functions of surfactants include: 1. Reduce surface tension: Surface active agents can reduce the tension of liquid surface, so that liquids are more likely to expand or penetrate into small pores when they come into contact with solid or other liquids, and improve the moisturizing performance of the liquid. 2. Diversified stability:…
The surfactant can be liquid or solid. Depending on the different chemical structure and physical properties, the surfactant can exist in liquid or solid forms. Some common liquid surface active agents include: anion surfactants (such as sulfate, sulfate, sulfonate, carboxylic acid salt, etc.), cationic surfactant (such as ductinium salt), non -ionic surfactants (such as polyether,…
Surface active agent is a type of chemical with a special chemical structure that can reduce the surface tension of the liquid surface and make the liquid have good wetting and decentralization. Surface active agents are usually composed of hydrophilic groups and hydrophobic groups. The hydrophilic group likes water, while hydrophobic groups like oil or…
The main component of the flocculant can be inorganic or organic objects. Common inorganic substances include aluminum salt (such as polymerized aluminum sulfate) and iron salt (such as polyacox chloride). Common organic objects are polyacrylamide. The main purpose of flocculant is that during the process of water treatment and sewage treatment, the suspended substances and…
