In recent decades, due to the water crisis and the increase in factory productions relative to the population growth, the issue of water and wastewater treatment has become an important matter globally. This has led to the increasing attention of all industries and governments to advanced wastewater treatment methods.
Now that the importance of water and its recycling in industrial plants has been established, we examine modern treatment methods using chemicals, one of which is Polyelectrolyte or Flocculants. These are natural polymer chains made of carbon atoms and active groups. The primary function of these natural chains is such that when they react with suspended water particles, they hold together a large number of these water-soluble or wastewater particles like a magnet and cause their agglomeration.
These particles, now connected in a chain-like formation, weigh more than other particles and quickly settle due to their high weight. The settled substances and sediments collect at the bottom of the container or tank, and the treated and usable water can be separated from these sediments.
Polyelectrolyte is indeed a very practical chemical in the wastewater treatment industry. Today, modern wastewater treatment methods with the help of chemicals for recycling water in factories and various industries have been widely welcomed, with Polyelectrolytes being one of these materials.
Polyelectrolytes or Flocculants consist of natural polymer chains comprising a collection of carbon atoms and active groups. Their primary function is such that when they react with suspended water particles, they hold a large number of particles dissolved in water and wastewaters together like a magnet, causing their agglomeration.
Now the particles connected to each other in a chain-like form weigh more compared to other particles and therefore, due to their heavy weight, will quickly settle. These settled substances and sediments will accumulate at the bottom of containers in tanks. Thus, the water that has been treated and is usable can be separated from these sediments.
The main difference between these two types of flocculants lies in the charge they carry. Anionic flocculants carry a negative charge, and cationic flocculants carry a positive charge. This difference in charge leads to different properties in them, and the outcome of these two materials working together is different.
Polyelectrolyte
The colloidal property of imported flocculants, as we discussed earlier, is crucial in the wastewater treatment process. When solid particles clump together, a specific cohesive and attractive force between them arises, forming a mass within the liquid, which then settles.
If the colloidal particles of polyelectrolytes tend to attract a negative charge, they are of the cationic or positively charged type because, as we know, positive charges are attracted to negative charges and vice versa.
If polyelectrolytes tend to attract a positive charge, they are of the anionic or negatively charged type. Another type of polyelectrolytes with neutral charge exists, but their application is very limited and not specific to the positive or negative charge of particles. Flocculants with positive charge are known as cationic, those with negative charge as anionic, and those with neutral charge as nonionic.
Application of Polyelectrolyte
It's noteworthy that there are three methods for producing anionic, cationic, and neutral polyelectrolytes, which are produced in both liquid and powdered forms. For the production of anionic electrolytes, three types of raw materials are typically used: acrylamide, acrylic acid, and sodium hydroxide. Cationic polyelectronics are obtained from a mixture of acrylamide and methyl acrylate chloride monomer.
Neutral polyelectrolyte is made by polymerizing acrylamide into polyacrylamide. These compounds are produced in high quantities in both synthetic and natural forms. Interestingly, the most common natural polyelectrolytes include pectin, alginate, carboxymethyl cellulose, and polypeptides. The synthetic types include materials such as polyacrylic acid, polystyrene sulfonate, polyallylamine, carboxymethyl cellulose, and their salts.
To determine which type of polyelectrolyte can have a better effect on a particular wastewater substance, it's essential to know the electrical charge of the colloids suspended in water, whether positive, negative, or neutral.
If these suspended particles carry a negative charge, then cationic polyelectrolytes with a positive charge should be used. If the charge of these particles is positive, then anionic polyelectrolytes with a negative charge should be used. If the charge of the particles is neutral, neutral polyelectrolytes should be used.
