7. NSF Test
NSF International conducted a Performance Evaluation of VBTTM to Schedule 40 standards over 6 months.

8. NSF Test
Average TSS reduced from 212 mg/L (influent) to 36 mg/L (effluent) - 83%
Reduction in highest loading TSS (1,300 mg/L) by 95%

9. Summary of NSF Tests – Suspended Solids
83% Average Reduction

10. Trinity River Authority of Texas (TRA) Evaluation
A series of samples were taken from a standard septic tank installation over a period of 9 months.
Three tanks – initially with VBTTM in second tank only.
Later, second VBTTM added to first tank.

11. TRA Results With only 1 VBTTM - TSS reduced by 69%
With second VBTTM added
- TSS reduced by 79%
- Discharge to disposal field at less
than 30 mg/L
