Water treatment agents are used in wastewater and sewage treatment, cooling water, seawater desalination, biological treatment, etc. Widely used in chemical, petroleum, light industry, daily chemical, textile, printing and dyeing, construction, machinery and other industries.
Polyacrylamide (PAM) is a linear polymer. It is a glassy solid at room temperature and can be dissolved in water in any proportion, and its aqueous solution is a transparent liquid, which is generally used in the flocculation process.
Polyaluminum chloride (PAC) is commonly used in the coagulation process. It comes in a variety of colors, such as white, pale yellow, golden, brown, tan and brown. Among them, white has the highest purity, light yellow is relatively high-end, and it is often used for drinking water treatment.
Caustic soda, also known as sodium hydroxide, is an inorganic compound that is mainly used to regulate PH. In addition, caustic soda can filter heavy metal ions to a certain extent by precipitation.
Biological bactericides Biological preparations are generally liquid, powder, particles, etc. Microbial supplementation for biological treatment in wastewater treatment.
Carbon sources Nutrients that contain carbon and can be used by microorganisms for growth and reproduction are collectively referred to as carbon sources. We often have sugars, fats, organic acids, etc.
Citric acid, is an important organic acid. It is mainly used for backwashing of MBR system, which can dissolve the salt compound dirt on the surface of MBR film.
Sodium hypochlorite is an inorganic compound used in water treatment as a water purifier, fungicide, disinfectant and backwash of organic contamination of MBR membranes.
So we can understand that there are many kinds of water treatment agents, and different water treatment agents have different mechanisms of action and uses.
