Wastewater solutions

Providing reliable mechanical screening to reduce solids loading on secondary wastewater treatment

High-Quality Effluent Flows to the Bottom Line

Duperon helps customers achieve a high-quality effluent and reduces operating expenses in food and beverage wastewater processing. 

  • It begins with simple, reliable screening that handles the unique conditions of your plant, with minimal downtime or maintenance.
  • By removing the bulk of the solids loading, it allows the downstream treatment processes to operate as it should; problem-free, reducing costs and ensuring uninterrupted production.
  • Screening improves the efficiency of process water treatment to meet regulations, product quality demands and maintain environmental compliance.
  • All of which allows you to focus your resources on production rather than treatment.

Reliably removing solids through screening is an effective strategy to reduce biological oxygen demand (BOD), fats/oils/greases (FOG) and other waste by-products. Screening can also reclaim materials for beneficial use that would otherwise undergo disposal or require costly additional treatment.

The simple design and durable materials of Duperon screens not only allows them to perform under a range of process demands such as high organic loading, batch processing, various debris, temperature, PH levels, and flow conditions but ensures a long product life.
