The role of water treatment agents is to improve water quality and meet the growing demand for clean, safe and usable water. By eliminating harmful substances in the water, water treatment agents help prevent scaling, corrosion, bacterial and algae growth, etc., thus providing efficient, safe and long-term operating conditions for industrial production. Common water treatment agents are:
Polyaluminium chloride (PAC): is an inorganic polymer with properties between AlCl3 and Al(OH)3, with strong adsorption capacity and a bridging effect during hydrolysis. It is mainly used in the coagulation process to purify water quality through physical and chemical adsorption, precipitation and other processes.
Flake soda: also known as sodium hydroxide, is an inorganic compound, mainly used to adjust the pH value, because flake soda is a strong alkaline substance, while conventional sewage is mostly acidic. It is mainly used in air flotation tanks or regulating tanks, and a reasonable pH environment can also avoid the phenomenon of sludge floating. In addition, flake alkali can filter heavy metal ions to a certain extent through precipitation.
Biological fungicide: refers to the fermentation broth of bacteria adsorbed by using porous substances as adsorbents (such as peat and vermiculite) after the target microorganisms (effective bacteria) are propagated through industrial production. Generally liquid, powder, granules, etc. In wastewater treatment, microorganisms are supplemented for biological treatment.
Carbon source: Refers to a substance that contains carbon and can be used by microorganisms for growth and reproduction. They are the food of microorganisms, providing them with energy and a carbon frame for their synthetic products. Carbon sources can include many different substances such as sugars, oils, organic acids, etc.
In addition to chemicals, materials such as ion exchange resins, membranes, and activated carbon are used in water treatment. If you want to know more about water treatment chemicals or materials, you can continue to ask me questions.
