Surfactant additions to optimize the anti-biofilm activity of chlorinated disinfectants for industrial cleaning

在石油和天然气工业中，生物膜会造成生物结垢、生物腐蚀、生物成因油层酸化和机械堵塞。这些破坏性的影响导致了许多操作问题，如腐蚀失效、产量递减、过滤器堵塞和注水能力损失。生物膜是包裹在细胞外聚合物基质中的微生物菌落，可以保护微生物免受消毒剂和剪切力的影响。生物膜在油气田的露天池塘、供水井、过滤器、管道和储油罐中以黏液聚集体的形式发展。通常用于去除管道内生物膜的大量传统消毒剂(戊二醛和季铵表面活性剂)在许多工业场所被证明是无效的。因此，需要比传统方法更快有效地针对细菌生物膜的消毒剂。

In the oil and gas industry, biofilms cause biofouling, biocorrosion, biogenic reservoir souring and mechanical blockages. These destructive effects lead to many operational problems such as corrosion failures, production decline, filter plugging and loss of injectivity. Biofilms are microbial colonies encased in an extracellular polymeric matrix, which protects from disinfectants and shear forces. Biofilms develop as slime aggregates in open ponds, supply wells, filters, lines, and storage tanks in oil and gas fields. The huge amounts of conventional disinfectants (glutaraldehyde and quaternary ammonium surfactants) that are normally used to remove biofilms from within pipes have proven to be ineffective in many industrial sites. Thus, there is a need for disinfectants that efficiently target bacterial biofilms more rapidly than conventional methods.
