Tersus Celebrates 10th Anniversary
Tersus is extremely proud to be marking our 10th anniversary with the support our dedicated associates, collaborative partnership,and loyal clients. It is quite the accomplishment for the company to reach the 10-year milestone given that the Bureau of Labor Statistics’ Business Employment Dynamics data indicates that less than ⅓ of all small businesses make it to the 10-year mark.
Featured Remediation Approach
Tersus Advanced Surface Kinetics (TASK™) liberates NAPL and captures them with enhanced recovery techniques.
Do I have DNAPL at my site?
It is difficult to verify the presence of DNAPL through direct observation. A common practice is to estimate the presence of DNAPLs indirectly by applying the “1 percent of solubility” rule-of-thumb (EPA, 1992).
Optimizing Anaerobic Bioremediation
Nutrimens® Granular, Enhancing the Efficiency of Electron Donor Utilization in Bioremediation
Bacteria are very sensitive to low pH. The optimal pH for bioremediation is between 6 and 8.5. To keep your in situ bioremediation project on track, pH should be maintained within a range where bioremediation is maximized. In general, more fermentation means more volatile fatty acid (VFA) production and lower pH. A major consequence when pH falls below 6 is a dramatic decline in enhanced reductive dechlorination.
