Biological BOD and TSS Removal

In a treatment plant the vast majority of carbon and solids are removed by the biological system. A well designed biological system can achieve 10 mg/l or less of BOD and TSS.

• Time flexibility ensures optimum removal of BOD even at varying influent conditions
• True batch systems include polishing steps without influent BOD for maximum removal
• Settle phase without inlet flow allows for the best available TSS removal
• Ability to increase settle phase in biological systems enhances TSS removal even at adverse conditions.
