The shelf life of reverse osmosis dirt depends on the specifications of specific products and manufacturers. Generally speaking, the shelf life of reverse osmosis resistors is usually between 1 and 2 years, but please note that this is just a rough time range, and the specific situation may be different. Before using reverse osmosis dirt,…

Polymer flocculants are a type of chemicals widely used in water treatment, sewage treatment and other fields. It is used to gather small particles suspended in water into large blocks, which is convenient for subsequent precipitation and filtration. Here are some common types of polymer flocculant: Polyacrylamide (PAM): Polyacrylamide is a widely used polymer flocculant…
The main components of good flocculants commonly used in water treatment sewage include the following: Polyaluminium chloride (PAC): Polyte aluminum chloride is an inorganic flocculant. The main component is aluminum chloride and aluminum water. It has good flocculation performance and extensive applicability, which can quickly gather and precipitate solid particles that are suspended in water….

Bacteridine is a type of chemical that is used to kill or inhibit the growth of microorganisms (such as bacteria, fungi, and viruses). According to the different mechanisms and application fields, the bactericide can be divided into the following categories: Disinfectant: disinfectants are mainly used to kill harmful microorganisms such as bacteria, fungi, and viruses…
The processing process of sewage turning water usually requires multiple steps and methods. The following are some common sewage treatment methods, which can help sewage become clear water: Physical treatment: Physical treatment remove solid suspension, sediments and floating objects through filtering, precipitation, stirring and other methods. Common physical treatment methods include grille, sand tank, sedimentation…

The following three basic methods can usually be adopted: sewage treatment: Pre -treatment (pre -processing): Preliminary treatment refers to preliminary treatment of sewage to remove large particles and suspension. This usually includes the use of grids, sand sink ponds, adjustment pools and other equipment. Through pre -processing, the impact of subsequent processing equipment can be…
Water treatment chemical materials are chemicals used to treat sewage, water supply and wastewater. Here are some common water treatment chemical raw materials: Setric agent: The concrete process is used in the concrete process in sewage treatment, helping to gather suspended particles and colloidal substances to form a large sediment, which is convenient for subsequent…
Chemical dispersion is a type of chemicals widely used in multiple fields. It is mainly used to disperse solid particles or liquid droplets to liquid medium and prevent them from re -aggregating. The following are several common uses of chemical dispersing agents: Surface active agent: Chemical dispersant can be used as a surfactant, so that…
Chemical dispersing agents mainly play the following functions: Disclosure: Chemical decentralizers can evenly disperse solid particles or liquid droplets to liquid medium. By changing the surface properties of the particles, such as surface charge, hydrophobicity, etc., they reduce the interactive force between particles and prevent the particles from re -converging. This decentralized effect keeps the…
Differentians are additives commonly used in chemical, material science and pharmaceutical fields, which are used to promote the dispersion and stability of particles or solid substances in liquid. Depending on the mechanism and chemical nature of its role, common dispersers can be divided into the following categories: Surface active agent (surfactant): Surface active agents are…
