Bench Testing Instructions
White Paper

Bench testing is the most effective tool for ensuring wastewater systems run smoothly. It helps verify chemical requirements, check dosing, determine proper pH levels, and assess solids production in the treatment process.
For facilities with NPDES or Pretreatment Permits, bench testing is essential to confirm that wastewater treatment meets discharge requirements.
Key benefits of bench testing:
- Compliance: Ensures wastewater is treated within discharge limits for contaminants.
- Optimization: Identifies opportunities to reduce sludge production or adjust chemical use for better efficiency.
