PT Petrolog Indah carried out maintenance and operational support for the fluid and operational water treatment systems at SLB Duri, including the replacement and refurbishment of filter media. The work aimed to restore the reliability and filtration efficiency of the systems to ensure smooth operations and minimize the risk of unplanned downtime.

The scope of work included draining and removing degraded filter media, such as activated carbon, multimedia, and resin, followed by an inspection of the internal condition of the vessels, lateral strainers, and internal distributors. New filter media was then installed in accordance with the manufacturer's technical specifications, followed by backwashing, flushing, pressure drop measurements, and assessments of output water quality parameters to ensure the systems returned to optimal performance.
