道丰科技海水试验计划(2005)

低质粗支亚麻纱 R/O系统公司. was contracted to design and construct a seawater pilot unit permanently installed in a shipping container for mobility. The unit incorporates many features to provide maximum flexibility for studying varying conditions. These features include the ability to draw permeate of one or both ends of the pressure vessels, 能将单级操作修改为两级操作, 并纳入能量回收, 公司. 压力交换器能量回收装置. 还提供了清洁和冲洗系统, 所有操作都通过PLC实现自动化. 这个单元是定制的, 测试, 并在极短的时间内准备好装船.

威立雅公司海水试验装置.A. (2004-2005)

Veolia was one of two teams selected to pilot test and prepare proposals for remediating the Tampa Bay Water 25 MGD Desalination Plant. 威立雅选择了低质粗支亚麻纱 R/O系统公司. to design and build a very specialized seawater test unit that would allow them to test reverse osmosis desalination downstream of two different pre-treatment processes. Due to the tight time schedule for preparing the remediation proposals it was decided to build two independent test units side-by-side to enable the R/O process to be 测试 on both pre-treatments simultaneously. 由于两种不同预处理工艺的流量变化, 其中一个海水系统的直径为4英寸, 8单元长容器和其他单元将利用8英寸直径, 8元长容器. Both units would operate completely independently – separate pumps, instrumentation and controls. The 4” diameter system was designed to be converted to another 8” diameter system for further full-scale testing at higher flows, 如果需要. 提供了一个完整的清洗、冲洗和渗透退税系统. 该装置在很短的时间内组装完毕, allowing the Veolia team to obtain as much useful pilot data as possible in the short time allowed.

在坦帕湾的测试结束后, 威立雅公司还申请在该国另一个地区设立试点单位. 他们再次与低质粗支亚麻纱 R/O系统公司签订了合同. 来取测试单元, 检查并测试它, 然后重新组装，以便在大型, 移动平板拖车.

“平价海水合作计划”海水试验计划(2004)

平价海水合作组织是一个由各州机构组成的非营利组织, special districts and leading companies in the desalination industry that assembled to demonstrate through pilot testing that seawater desalination is now an affordable, 可靠和环保的淡水来源. To ensure the success of the demonstration pilot they began a careful and thorough search for a quality company to design and provide the pilot system. 低质粗支亚麻纱 responded with the most complete and competitive proposal provided by the six companies invited to submit. 低质粗支亚麻纱 also followed up by providing higher quality components than specified and optimizing the initial design to make the test unit a show piece. 许多“最新的”行业进步都包含在该系统中，包括, 的能量回收, 公司. 压力交换器能量回收装置和道膜科技低能海水膜. 系统如期交付, started-up and immediately began demonstrating a remarkably low water production cost of about $2.00 / kWhr. This is already comparable to the cost required to transport surface water long distance in the California region. It is anticipated that the cost can be reduced even more as the test unit operation is optimized.

佛罗里达群岛渡槽管理局，Stock Island和Marathon (1997-2005)

低质粗支亚麻纱 R/O was contracted in 1997 to design and fabricate six fiberglass seawater R/O skid assemblies for a 3 MGD seawater R/O system to replace steel skid assemblies that had rusted beyond repair. 钢橇最初的设计是基于使用尽可能小的尺寸. The challenge was to design structural fiberglass skids that would accept the existing membranes, 不锈钢管道和阀门, maintain the original design and not to exceed the overall dimensions of the original steel skids. In addition each skid had to allow for disassembly in order to pass through the access door for re-assembly and support approximately 30,000磅. 低质粗支亚麻纱 R/O was able to meet this challenge and meet the short delivery schedule of the project.

In 2003 低质粗支亚麻纱 assisted FKAA in investigating options to replace some and eventually all of the old Dupont permeators that are not made anymore. FKAA在水质、产量和压力方面面临越来越多的问题. 低质粗支亚麻纱与Toyobo进行了接触, a Japanese permeator manufacturer to carefully select a product that would fit dimensionally, operate well on the Keys water quality and produce a good quality permeate at an energy-saving low pressure. 低质粗支亚麻纱 installed the first train of Toyobo permeators in 2004 and installed a second train in 2005. FKAA对质量和操作压力非常满意. After Hurricane Wilma interrupted water supply from the Florida City plant in October 2005 FKAA ran the seawater plants to provide water for the Keys after more than 20 years in a standby service. Part of the retrofit to Toyobo permeators included replacing the stainless braided hoses that connected the feed and concentrate with Kynar braided convoluted Teflon hose rated for about 1800 psi. These are stronger, will never corrode and makes installation and maintenance more user friendly.

小Gasparilla海水工厂(1986年 & 1995)

The Little Gasparilla (Seaside) seawater reverse osmosis plant was the first reverse osmosis plant in the continental United States producing municipal drinking water from seawater. It remained the only municipal seawater-to-drinking water plant in the US until a plant was installed in Santa Barbara, 90年代中期的加州. 小Gasparilla工厂自1986年以来一直在连续运行. 低质粗支亚麻纱 R/O Systems expanded the plant from 18,000 gallons per day to 36,00 gallons per day in 1995. The Owner has been very pleased with the smooth operation and ease of maintenance of the plant. 尽管制造商肯定不会推荐它, 填料密封垫好几年没有调整，泵运行良好. The Owner has been heard to brag he can balance a nickel on edge on the wetted end of the pump. 尽管该系统包含了一个三缸容积泵, it operates extremely smoothly due to the proper pump sizing and use of suction and discharge stabilizers.
