The Polymer Removal System utilises various principles and techniques to eliminate polymers and reduce their COD content from industrial processes.
One of the main principles utilised in this system is the coagulation and flocculation technique, in which chemical agents play a vital role. These agents are specifically designed to dissolve or break down polymer compounds, making them easier to eliminate. The choice of chemical agents depends on the type of polymers encountered and the specific needs of the industrial process.
The system uses Concentrated Sulfuric Acid Solution (98% H2SO4) to lower the system’s pH to a range of 6.5 to 9.0. Poly-Aluminium Chloride (20% PAC) acts as a coagulant by neutralising charges in the mixture, allowing small groups of particles to come together. The system also introduces polymers to help these small particle groups form flocs, facilitating faster settling time.
Furthermore, the Polymer Removal System may incorporate filtration or separation technologies to eliminate polymer particles or contaminants from process streams. Filtration techniques such as microfiltration or ultrafiltration can remove suspended polymer particles, resulting in cleaner process fluids and improved process efficiency.
By utilising mechanical, chemical coagulation, flocculation, and filtration principles, this system provides a comprehensive solution for efficient polymer removal. Through ongoing research and development, this technology has the potential to become a crucial component in enhancing efficiency, reducing maintenance requirements, and promoting sustainability in industrial operations.
