Biofilm Removal using Phosphate Buffer Saline

Main Article Content
Abstract
Biofilm represents a serious threat to water, medical and health facilities. Dealing with such an engineering problem may be pre or post formation. As a rough speech, there is no pre-treatment method could stop biofilm formation completely while post treatment cost a lot of expenses and resources. This gives the potential to explore a method helping to remove and disinfect biofilms completely. In its quantification, Phosphate Buffer Saline (PBS) was used to release biofilm from coupons that mounted in various laboratory scale reactors. This sparks the idea of using this substance to remove biofilm after its foundation. To explore that, the two controlling variables of exposure time and PBS concentration were examined against biofilm percentage removal. Results were promising and gave a strong potential for practical and commercial use.
