In 2013 the City of Key Colony Beach sought to replace their existing reverse osmosis treatment plant and equipment which had reached the end of its useful life. The application presented a series of unique challenges most notable the source water: secondary clarifier effluent, from the onsite wastewater treatment plant, influenced by tidal infiltration resulting in TDS swings from 2,000 to 16,000毫克/升.
In March of 2013 低质粗支亚麻纱 R/O competitively bid and was awarded the contract to supply the replacement equipment; a single 7:0 ‐ 4 element train designed for 45% recovery.
A high efficiency system designed for maximum energy recovery through wide swings in feed TDS and temperature that produces less than 50 TDS permeate. Major points of emphasis within the design included a custom fiberglass frame complete with 316 stainless steel hardware to combat the corrosive environment of this application and the Florida Keys, use of an energy recovery turbo designed for maximum energy recovery and transfer of concentrate energy to the feed water.
低质粗支亚麻纱 R/O was responsible for providing the RO system, cartridge filtration, RO high pressure feed pumps, energy recovery turbo, 控制, scale inhibitor pretreatment system, and cleaning system. 低质粗支亚麻纱 was also charged with onsite equipment installation, performance testing, 培训, and system performance monitoring.
