The effective use of non-oxidizing biocides is critical for maintaining microbial control in water treatment applications. A variety of methods and approaches may be used to improve and optimize biocide efficacy in these systems. Results of efficacy testing have shown improved killing of bacteria by biocides with the addition of selected surfactants and adjuvants. Enhanced microbial control may also be achieved by combinations of certain biocides which display a synergistic effect on mixed populations of organisms. Studies have also shown the benefit of rotating or alternating biocides to control resistant organisms which may develop following use of low doses of a single biocide. Collectively, these approaches may enhance the degree of control achieved in a given water system. Other ways to provide additional knowledge on biocide dosing and microbial control may be achieved through the use of model biofilm systems.

Biocorrosion or microbiologically influenced corrosion (MIC) is a major problem in the oil and gas industry. Biofilms are the culprits of MIC. In this work, D-amino acids were used to enhance two biocides, alkyldimethylbenzylammonium chloride (ADBAC) and tributyl tetradecyl phosphonium chloride (TTPC), to treat a field biofilm consortium on C1018 carbon steel coupons.

An oil transmission pipeline in the Eagle Ford area was being treated with 150ppm of active biocide based on a five percent water hold up but good control of the microbial population was not being maintained.
