CLEANING & DISINFECTION PROCESS To be completed in early Spring (March/April) and late Fall (October/November) dependent on weather conditions and scheduled through the COR. The following stages highlight the general approach for cleaning and disinfection of cooling water systems. Certain modifications may be required depending on system access, design, operation or the like. All stages in the clean and disinfection process shall require assistance from the Customer such as the operation engineer who is familiar with the system. All supplies and PPE will be contractor supplied. Proper LOTO will be utilized as needed. Stage I Pre-Clean Disinfection for the destruction of biofilms and pathogens All cooling tower fans must be shut OFF and proper LOTO procedures in place prior to start of process, and all recirculation pumps must be ON. The system is disinfected using an oxidizing biocide such as chlorine or an equivalent chemistry. A bio dispersant may also be added to help remove organic deposits and enhance disinfection. Stage II Mechanical Cleaning for surface sanitation and removal of deposits Each system cell and/or sump is isolated and drained for mechanical cleaning. Each system cell is pressure washed from top to bottom, internal and external, as is reasonably accessible to remove deposits. Exceptional care is taken to remove deposits without damaging the fill pack. Deposits, including the sump if included in the scope, are removed for disposal. The Customer shall assist with disposal in the appropriate dumpsters or equivalents. Stage III Post-Clean Disinfection for the destruction of dislodged biofilms and pathogens. All cooling tower fans must be shut OFF, and all recirculation pumps must be ON. The system is disinfected using an oxidizing biocide such as chlorine or equivalent chemistry. The full water treatment program must be immediately resumed following the disinfection step to re-passivate system metallurgy. Stage IV Documentation and Certification The cleaning and disinfection service is documented with a service report with photos and a certificate for a record of due diligence. Documentation supports a site risk reduction program for control of Legionella in cooling water systems. SEASONAL START UP/SHUTDOWN The vendor will do a full check and start-up of all cooling towers and fluid coolers ensuring full operability. Clean debris from the platform and surrounding area. Clean water sump and check condition. Check make-up valve operation and adjust accordingly. Check and clean bleed-off line and overflow. Clean tower strainers.
