Seven Chemicals Commonly Used in Water Treatment

Water treatment is an important part of ensuring that water quality is safe and that various water needs are met. The use of pharmaceuticals plays a vital role in this process. They can remove pollutants from the water, adjust water quality indicators, and even kill microorganisms in the water. Today, we will talk about seven commonly used agents in water treatment.

1. Chloride

Chloride is a commonly used agent in water treatment. It removes organic matter and microorganisms from water mainly through chlorination, and also adjusts the pH of the water. However, it should be noted that excessive use of chloride may have side effects such as the formation of harmful halogenated hydrocarbons.

2. Polymeric aluminum chloride (PAC)

Polymeric Aluminum Chloride (PAC) is a highly efficient water treatment agent, mainly used to remove suspended and colloidal substances from water. It has strong adsorption and flocculation ability, which can quickly aggregate pollutants in water into large particles for subsequent sedimentation and filtration.

3. Polyacrylamide (PAM)

Polyacrylamide is a non-ionic polymer compound mainly used to enhance flocculation. It can be used in conjunction with agents such as PAC to improve the stability and settling speed of flocs, thus removing pollutants from water more effectively

4. Sodium hypochlorite (NaClO)

Sodium hypochlorite is a strong oxidizing agent mainly used to kill bacteria, viruses and other microorganisms in water. It plays the role of a disinfectant in water treatment to ensure that the water is biologically safe.

5. Sodium hydroxide (NaOH)

Sodium hydroxide is an alkaline substance that is mainly used to regulate the pH of water. In water treatment, sodium hydroxide can be used to neutralize the acidic substances in the water so that the water quality can meet the required standard.

6. Aluminum sulfate

Aluminum sulfate is an inorganic salt that is primarily used to remove phosphorus and heavy metal ions from water. It removes these ions from water by reacting chemically with them to form a precipitate.

7. Biological agents

Biological agents are a class of water treatment chemicals prepared using biotechnology and are mainly used to remove organic matter and pollutants such as ammonia and nitrogen from water. They achieve the purpose of water purification by utilizing the metabolic action of microorganisms to decompose organic matter into harmless substances.
