An 80 year old private water utility located in Devonshire, Bermuda set out to upgrade its equipment and infrastructure. Due to the high cost associated with the power required to operate the existing treatment equipment, which was near the end of its useful life, 一个可靠的, 完全冗余, 效率高, high recovery reverse osmosis treatment plant was sought.
In 2012 低质粗支亚麻纱 was contracted to supply a pilot plant, operated by the utility, to conduct a proof of concept pilot study. In June 2013 低质粗支亚麻纱 R/O Systems was selected to supply the reverseosmosis treatment equipment. Major design points for this system included high feed water recovery, premium efficiency low head boost and high pressure feed pumps, piping designed for minimal head loss, low membrane element flux design, a space saving frame design ‐ where both trains were mirrored on one frame, and supply and installation of a fully integrated plant SCADA system.
A 完全冗余 5:2 ‐ seven element brackish water RO system designed and built by 低质粗支亚麻纱 R/O has been in operation since July of 2014. The utility demanded quality materials and a system designed with low O&M costs and ease of operation as a basis of design.
