Sunresin's Solutions for Phenolic Wastewater Decontamination and Resource Recovery

In the realm of industrial chemical processes, phenolic compounds are indispensable. They serve as foundational raw materials and intermediates in the production of a myriad of products, from dyes and pesticides to adhesives and photographic developers. However, the use of these compounds invariably leads to the generation of phenolic wastewater, a byproduct that, due to its inherent toxicity, poses a significant threat to environmental health. Addressing this challenge, Sunresin presents a sophisticated solution that not only neutralizes this threat but also recovers valuable resources from phenolic wastewater.
Sunresin's Approach to Phenolic Wastewater Treatment:
Sunresin has developed a comprehensive treatment system capable of processing large volumes of phenolic wastewater with remarkable efficiency. In a case study, our treatment facility, designed to handle 50 cubic meters per day, successfully reduced phenol concentrations from an initial 10,000 mg/L to below 20 ppm. This level of purification is achieved through a meticulously designed process that includes precision filtration to remove mechanical impurities and insoluble solids, preparing the wastewater for the subsequent resin-based treatment.
The Seplite® LWT510 Series: A Leap Forward in Resin Technology:
At the heart of our treatment solution is the Seplite® LWT510 series of resins. These high specific surface area, non-polar, macroporous adsorption resins are the product of extensive research into the molecular structure of phenolic compounds. They are engineered for the efficient adsorption and removal of a broad spectrum of phenolic compounds from wastewater. Demonstrating an adsorption and removal rate of over 99%, the Seplite® LWT510 series resins have set a new standard in the industry for phenolic wastewater treatment.
The Science Behind LWT510 Type Adsorption Resin:
The LWT510 type adsorption resin operates on the principle of van der Waals forces, which include hydrogen bonds, orientation forces, induction forces, and dispersion forces. These interactions facilitate the adsorption of organic solutes from wastewater onto the resin surface. The high specific surface area of the resin enhances its adsorption capacity, while its ability to form hydrogen bonds with solute molecules significantly improves selectivity, promoting the efficient separation of harmful solutes from the water, thereby purifying the wastewater.
The desorption process, which allows for the removal of these adsorbed solutes, is efficiently carried out using appropriate desorbents, enabling the resin to be regenerated and reused, reflecting Sunresin's commitment to sustainable practices.
Advantages of Sunresin's LWT510 Series Resins:
  • High-Efficiency Treatment: Sunresin's LWT510 series resins deliver exceptional adsorption and removal efficiency, along with straightforward regeneration, supporting continuous and uninterrupted treatment cycles.
  • Substantial Processing Capability: These resins are capable of treating large volumes of wastewater without compromising on performance, indicative of their robust processing strength.
  • Longevity and Stability: Designed for durability, the LWT510 series resins maintain stable performance over extended periods, ensuring a long service life.
  • Broad Applicability: The versatility of the LWT510 series resins is evident in their wide range of industrial applications, demonstrating their adaptability to various operational conditions.
  • Value Recovery: The system's ability to efficiently recover phenolic compounds aligns with Sunresin's vision of creating value through sustainable resource recovery, reducing environmental impact while enhancing economic returns.
