Reduction of Total Suspended Solids - Precursor of Sludge Formation -

Animal Waste Lagoons (CAFO)

VBTTM Impact on Total Suspended Solids(TSS) – Iowa Dairy 65% Reduction in TSS in First 60 Days

Total Solids (mg/L) VBTTM Impact on Total Suspended Solids (TSS) – California Dairy Trend Line 39. 5% Reduction in Total Solids Time

On-Site Sewage Facilities (OSSF) Testing

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

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

Summary of NSF Tests – Suspended Solids (mg/L) 83% Average Reduction

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

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

Single VBTTM Effect on TSS

Reduction of Biological Oxygen Demand (BOD) - Precursor of Sludge Formation -

VBTTM Impact on BOD 5/VOC - California Dairy - BOD (mg/L) 83% Reduction in BOD Trend line

VBTTM Impact on BOD 5/VOC - Iowa Dairy 75% Reduction in BOD 5 in First 60 Days

On-Site Sewage Facilities (OSSF) Testing

NSF International Test Ø Average BOD 5 reduced from 202 mg/L (influent) to 51 mg/L (effluent) - 74% Ø Reduction in highest loading BOD 5 (660 mg/L) by 89%

Summary of NSF Tests – BOD 5 (mg/L) 74% Average Reduction
