Chem-Clean: A Powerful Tool for Tertiary Filtration in Wastewater Treatment

Chem-Clean, a technology developed by USFilter/Zimpro, represents a crucial component in the realm of environmental and water treatment. Specifically designed for tertiary filtration, Chem-Clean focuses on the efficient removal of grease and oil from wastewater, ensuring a cleaner and safer effluent discharge.

Tertiary filtration, the final stage of wastewater treatment, plays a critical role in removing remaining pollutants before the treated water is returned to the environment. While primary and secondary treatment focus on removing large solids and organic matter, tertiary treatment aims to eliminate the remaining contaminants, including grease and oil.

Here's how Chem-Clean works:

  • Chemical oxidation: Chem-Clean utilizes a powerful oxidation process that breaks down the complex structures of grease and oil molecules. This process converts them into smaller, more easily manageable particles.
  • Coagulation and flocculation: Following oxidation, the process utilizes chemical coagulants and flocculants. These chemicals cause the smaller oil and grease particles to clump together, forming larger, easily removable flocs.
  • Filtration: Finally, the flocculated particles are removed through a series of specialized filtration systems. This may involve sand filtration, membrane filtration, or other technologies depending on the specific requirements of the wastewater.

Key Benefits of Chem-Clean:

  • Efficient grease and oil removal: Chem-Clean boasts a high efficiency rate in removing even the most stubborn grease and oil residues.
  • Enhanced effluent quality: By effectively removing these pollutants, Chem-Clean ensures a cleaner and safer wastewater effluent discharge, meeting stringent environmental regulations.
  • Reduced maintenance costs: The robust design and reliable performance of Chem-Clean minimize the need for frequent maintenance, contributing to long-term cost savings.
  • Environmental protection: Chem-Clean promotes environmental sustainability by ensuring that discharged wastewater does not negatively impact the surrounding environment.

Applications of Chem-Clean:

Chem-Clean finds wide applications in various industrial settings, including:

  • Food processing plants: Handling large volumes of wastewater containing fats, oils, and greases.
  • Metalworking facilities: Dealing with cutting fluids, lubricants, and other oil-based contaminants.
  • Petroleum refineries: Managing wastewater containing hydrocarbons and other oil derivatives.
  • Wastewater treatment plants: Enhancing the overall efficiency of tertiary filtration processes.

Conclusion:

Chem-Clean by USFilter/Zimpro stands as a valuable asset in the field of environmental and water treatment. Its effectiveness in removing grease and oil from wastewater, coupled with its numerous benefits, makes it a crucial component for achieving clean and safe water discharges. By investing in Chem-Clean technology, industries can contribute to environmental protection and ensure responsible wastewater management.

Chem-Clean Exercise:

Task:

A food processing plant discharges wastewater containing high levels of grease and oil. They are currently using a traditional sand filtration system for tertiary treatment, but it is proving inefficient in removing these pollutants.

1. Explain why Chem-Clean would be a suitable solution for this plant.

2. Describe how Chem-Clean would improve the plant's overall wastewater treatment process.

3. Suggest two additional benefits the plant might experience by implementing Chem-Clean.

Exercice Correction

1. Why Chem-Clean is suitable:

  • Chem-Clean is specifically designed to remove grease and oil from wastewater, which is the primary concern of this food processing plant.
  • Traditional sand filtration alone is not effective in removing stubborn grease and oil residues, while Chem-Clean utilizes a multi-step process to effectively break down and remove these pollutants.

2. How Chem-Clean improves the treatment process:

  • Enhanced Effluent Quality: Chem-Clean will significantly improve the quality of the discharged wastewater by removing the grease and oil contaminants, resulting in cleaner and safer effluent.
  • Meeting Regulations: The improved effluent quality will help the plant meet stringent environmental regulations regarding pollutant levels.

3. Additional benefits:

  • Reduced Maintenance: Chem-Clean's robust design and reliable performance could lead to reduced maintenance costs compared to the traditional sand filtration system.
  • Environmental Responsibility: By effectively removing grease and oil, the plant can contribute to environmental protection and demonstrate responsible wastewater management practices.
