Achieving Tighter Limits for Pond-Based Treatment Systems with HySmart®

Across Australia and New Zealand aerated wastewater ponds are used by industrial manufacturers to provide a level of treatment that typically targets suspended solids and organic removal (BOD5). The process is generally easy to operate and maintain.

But what happens when a tighter limit is required?

Hydroflux recently completed the upgrade of a pond-based treatment system for a food and beverage processor to include treatment to achieve significantly higher levels of suspended solids, BOD5, phosphorous and nitrogen removal.

Project Highlights

• Capacity upgrade by 20% to 2.3MLD
• Total Nitrogen Limit revised to 15 mg/L
• Total Phosphorous Limit revised to 2 mg/L
• Wastewater characterization to determine process design
• All the guaranteed discharge limits were met (BOD, TSS, TP and TN)

Process Summary

• Conversion of the process to include anoxic and aerobic zones within the ponds
• Incorporation of floating surface aerators to the aerobic zone
• Addition of a final stage HySmart® Activated Sludge Process
• Secondary and tertiary treatment using HyDAF technology
• Sludge management using HySludge® technology
• Automatic control system and remote monitoring HyConnect®
• Process instrumentation and flow monitoring
