Containerized Seawater RO for Industrial Process in Freeport, Grand Bahama Island



A global manufacturer located in Freeport, Grand Bahama was facing a shortage of water required for their manufacturing process and other facility needs. The facility draws water from a single land-based seawater well on the property and is treated by media filters and a two-pass RO system. The local government also provides water but quantity, quality and availability is variable and unreliable forcing the manufacturer to be self-sufficient to avoid disrupting their operations. 现有的1st pass seawater trains were severely deteriorated from the demanding environment and corrosive materials of construction. A short delivery option was needed to immediately supplement their existing seawater trains to increase capacity and reliability.



低质粗支亚麻纱R / O was contacted through the manufacturer’s water services provider. 低质粗支亚麻纱R / O had a mobile containerized seawater RO system available for lease that was designed and built by 低质粗支亚麻纱R / O that would meet the manufacturer’s needs. The container was ready for shipment to Grand Bahama within 4 weeks and was started up within 8 weeks of agreement of lease terms.

The containerized seawater RO system designed and built by 低质粗支亚麻纱R / O has been running continuously since 2014年9月 with a high degree of reliability and efficiency because of the sound design and high-quality materials and components. The unit is expected to operate indefinitely until the existing equipment can be replaced or refurbished.
