Water treatment flocculant PAM (polyacrylamide) is a commonly used water treatment chemical that is widely used in the field of water treatment. It plays an important role in wastewater treatment, pure water preparation, sewage treatment, etc.
The main function of PAM is to condense it into larger particles by physical adsorption or chemical reaction with suspended solids and dissolved matter in water to form flocs that are easy to precipitate or filter. It is able to gather the tiny particles scattered in the water together, so that they can be easily processed and removed.
According to their molecular weight and ionization, PAMs can be classified as non-ionic, cationic, anionic, and mixed. Different types of PAMs are suitable for different water treatment scenarios.
Sewage treatment: PAM can quickly gather the small suspended solids in the wastewater to form a large floc, which is convenient for subsequent precipitation and filtration, and achieves the purpose of purifying water quality.
Pure water preparation: In the process of pure water preparation, PAM can help remove foreign matter and dissolved matter from the water, and improve the purity of the water.
Papermaking wastewater treatment: The wastewater generated in the papermaking process contains a large amount of cellulose and organic matter, and the non-ionic form of PAM can effectively condense these pollutants and improve the treatment efficiency of wastewater.
Printing and dyeing wastewater treatment: printing and dyeing wastewater contains a large number of dyes and suspended solids, and cationic PAM can form a precipitation complex with dyes, so as to achieve wastewater purification.
Mineral water purification: Mineral water often contains various cations, and anionic PAM can combine with these ions to form complexes, reduce the content of ions in the water, and improve the quality of water.
Pond water treatment: Pond water is complex and contains different types of pollutants, and mixed ionic PAM can treat these pollutants at the same time to achieve the purpose of purifying water quality.
Precautions
When using PAM, it is necessary to pay attention to reasonable control of the dosage to avoid waste caused by excessive use.
The use of PAM needs to be carried out under appropriate conditions, such as the pH value of water, temperature, etc., which have a certain effect on its effect.
When storing PAM, it should be stored in a dry, well-ventilated place and protected from moisture and sunlight.
In short, water treatment flocculant PAM is a chemical widely used in the field of water treatment, which can help remove impurities and suspended solids and improve water quality in the process of wastewater purification and pure water preparation. Choose the appropriate type of PAM according to different water treatment scenarios, and pay attention to the precautions for use and storage.
