Preparacion de polielectrolito: usage in water treatment factories

In most modern-day water-filtration units, industry owners tend to use techniques that aid cost-effectiveness and better filtration. One such method used nowadays is the implementation of polyelectrolytes. Preparacion de polielectrolito helps the filtration process through a range of advantages. They serve as primary water flocculants.

Why use polyelectrolytes for water treatment?

Impurities that are found in water come in both suspended and dissolved forms. The suspended water impurities tend to be non-biodegradable. This is why it is important to remove the suspended impurities from water. The method known as coagulation-flocculation is sustainable for different types of groundwater, surface water, industrial effluents, or synthetic water.

In the conventional scenario, inorganic coagulants can be used for flocculation-coagulation filtration. However, the drawback of this method is the high inorganic coagulant dosage. This also leads to poor results & the generation of a large amount of sludge.

This is why water treatment factories make use of organic polyelectrolytes in combination with inorganic coagulants to treat wastewater. The key is to opt for preparacion de polielectrolito with the right dosage.

Optimum Dosage for Wastewater Cleaning with Polyelectrolytes

The right dosage for the use of the polyelectrolytes in different types of water & industrial wastewater needs to be particularly low. This is especially true if it is being used along with the inorganic coagulants. With low dosage, the toxicity issue can fairly be chugged out. Plus, it is an environmental-friendly way to filter wastewater.

Several treatment factories use preparacion de polielectrolito in order to condition the sludge before vacuum filtration.

Polyelectrolytes are used for:

  • Raw water cleaning
  • Sludge dewatering
  • Color removal
  • De-oiling
  • Industrial processes
  • Paint detoxification

Coagulants are used to promote colloidal coagulation & smaller particle removal in raw water or wastewater. This helps in the removal of any additional water treatment steps. Polyelectrolytes are used as flocculants and filter aids to improve the overall cleaning performance in water supply units.

These electrolytes come in 3 different forms that include powders, solutions, and emulsions. The powders generally are available in colorless or white colors. On the other hand, the liquids are mostly white in color. These cleaning add-ons aren’t considered hazardous in any form, which includes inhalation, contact, or ingestion.

Properties and Applications of Polyelectrolyte


  • It can change the aqueous suspensions and solutions’ fluid properties
  • It interacts with the neutral particles
  • It interacts with the small ions
  • It interacts with the macromolecules that are oppositely charged


  • It is used as a thickening agent in food or other products as well as for the enhanced form of oil recovery
  • It is used as a dispersant or flocculant depending on the charge density and molecular weight
  • It is used as a water softener
  • It is used in the membranes that are selectively permeable

Also, keep in mind that the process of preparacion de polielectrolito might be completely biological in its origin, like the nucleic acids. Alternatively, they can also be synthetic. Polyelectrolytes might also be classified conveniently under the names cationic, anionic, or even ampholytic.

What are the physicochemical properties of polyelectrolytes?

Polyelectrolytes function as macromolecules which, when dissolved into polar solvents such as water, feature a large amount of the charged groups linked covalently to each other. These compounds occur in groups of cationic and anionic variants, and this molecule is termed the polyampholyte.

The special properties held within polyelectrolytes are similar to that of the uncharged polymers that deliver excellent solubility in water. It also includes their swelling propensity and the ability to bind large chunks of water. The polyelectrolytes interact in a strong manner with macromolecules and surfaces that are oppositely charged.

Due to these properties, preparacion de polielectrolito can be intimately connected with the strong interactions in the electrostatic manner of the polyelectrolyte solutions. They are also sensitive to water or any solution’s pH they are added to along with the type and amount of electrolytes found in this solution.

Polyelectrolyte is used in different fields like water treatment in the form of flocculation agents, dispersant agents in ceramic slurries, as well as super-plasticizers in concrete mixtures. The crosslinked polyelectrolytes tend to swell in the water & function as efficient water absorbers. They are also termed hydrogels. When they are slightly crosslinked, they are termed superabsorbent polymers.

The superabsorbers have the potential to absorb water about 500 times its weight & 30 to 60 times its volume. This thus helps in better wastewater management and treatment. With polyelectrolytes, the thickness, separation, performance, LbL charge, and surface hydrophilicity would differ depending on the concentration, type, pH, & the polyelectrolyte layer number.


The use of polyelectrolytes aids in the better management of wastewater by industries and factories on a large scale. It also allows precise control around the water treatment protocol while saving a lot of energy in the process. However, this process should only be implemented with the help of professional service providers for wastewater management.
