All pre-commissioning cleaning works are carried out to the guidelines set out in the BSRIA BG 29/2012 publication or, to the design criteria of the specific installation. The BSRIA BG 29/2012 “Pre-Commission Cleaning of Pipework Systems” outlines the methodology for the cleaning of new closed water systems. The guideline also illustrates design and installation requirements. We ensure the following: All chemicals used are compatible with multi-metal installations The suitable maintenance and sampling of closed water systems That chemical levels are maintained to prevent any corrosion or microbiological fouling That on older installations where a chemical clean may be deemed too aggressive, we can provide a raw water dynamic flush of systems and install a temporary sidestream filtration unit to aid in the removal of system debris.
