Chloromethyl-methylisothiazolone (CMIT/MIT) biocide is used for microbial control in industrial water treatment applications. It is effective versus various types of bacteria, algae and fungi. This paper will provide results of planktonic and biofilm efficacy studies with CMIT/MIT biocide versus various strains of Desulfovibrio.
The use of glutaraldehyde for decontamination and preservation of water systems involves important considerations relevant to its ecotoxicity profile, biodegradation properties and safe handling and storage guidelines. This paper will review data from ecotoxicity studies, in addition to biodegradability characteristics
In this paper the compatibility of the biocide tetrakis(hydroxymethyl) phosphonium sulfate (THPS) and the oxygen scavenger ammonium bisulfite (ABS) were explored. Performance testing of both the biocide in the presence of the oxygen scavenger and the oxygen scavenger in the presence of biocide are reported.
Observations and guidelines to conduct hydrostatic pressure tests of pipelines and/or process equipment. Concerns for hydrostatic pressure tests relate to the water itself, including any suspended solids, dissolved oxygen, or any Sulfate Reducing Bacteria (SRB) or Acid Producing Bacteria (APB) present in the test water.
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.
A three-phase production system in the North Sea was experiencing multiple leaks in the topside separation facilities. To control the microbial contamination in the system, an initial planktonic kill study was performed to select the best possible biocides to provide immediate microbial mitigation to the field.
