China Sewage Treatment Additives Manufacturers, Suppliers, Factory

Sewage treatment additive, as the name implies, is an additive that needs to be used in sewage treatment, such as polyacrylamide, cationic polyacrylamide, anionic polyacrylamide, nonionic, zwitterionic polyacrylamide, polyaluminum chloride, etc. It can be used as a sewage treatment agent in different purposes
Sewage treatment additives commonly used in sewage treatment process
In order to promote the reaction efficiency of sewage and activated sludge, it is necessary to apply a variety of sewage treatment additives in the treatment process. It can be roughly divided into the following categories:
1. Flocculant: Also known as coagulant, it can be used as a method to strengthen solid-liquid separation, and is often used in primary settling tanks, secondary settling tanks, flotation tanks, tertiary treatment or advanced treatment and other process links. Mainly used is polyacrylamide.
2. Coagulant aid: Any chemical agent that cannot be used alone as a coagulant in a specific water treatment process but can be used in conjunction with a coagulant to increase or improve the coagulation and flocculation effect can be called a coagulant aid. The auxiliary flocculant plays a role to enhance the coagulation effect. Commonly used are: polyacrylamide, activated silicic acid, bone glue, sodium alginate, safflower tree.
3. Conditioning agent: also known as dehydrating agent, used to condition the remaining sludge before dehydration.
4. Demulsifier: a surfactant that can break the emulsion, and remove the water in crude oil and heavy oil. It is mainly used in the pretreatment of oily wastewater.
5. Defoamer: Also known as defoamer, it is mainly used in sewage treatment to eliminate a large number of bubbles generated during aeration or stirring. In the process of food processing, it is a food additive that reduces surface tension, inhibits foam generation or eliminates foam that has been generated.
6. PH adjuster: used to adjust the pH value of acidic wastewater and alkaline wastewater to neutral.
7. Redox agent: mainly used in the treatment of wastewater containing oxidized or reduced substances.
8. Disinfectant: used in disinfection treatment after wastewater treatment or before reuse.

Polyaluminium Chloride

Polyaluminium Chloride

Qingdao Shuodi Environmental Protection Technology Co., Ltd. is a professional supplier of polyaluminium chloride. Polyaluminium chloride (PAC) is an inorganic substance, an inorganic polymer coagulant, referred to as polyaluminium. It has a high-charged polymer chain body, has a high degree of neutralization and bridging effect on colloids and particles in water, and can strongly remove micro-toxic substances and heavy metal ions, with stable properties. Due to the bridging effect of hydroxide ions and the polymerization of polyvalent anions, the produced polyaluminium chloride is an inorganic polymer water treatment agent with a relatively large molecular weight and a high charge.
