The system has provided continuous, quality feedwater to a downstream RO system for almost a year
Dow Water & Process Solutions, a business unit of the Dow Chemical Co., announced the results of a recent piloting focused on Dow ultrafiltration (UF) technologies that was carried out at its Global Water Technology Center in Tarragona, Spain, and has seen continuous high-quality feedwater supply to the reverse osmosis (RO) system downstream over a prolonged period.
The IsoTwist PureWaterMachine is an under-sink RO filter system optimized to treat city water using the existing water pressure. It makes up to 50 gpd of great-tasting water while taking up less space. The proprietary twist-off disposable filters are designed to make installation and replacement quick, easy and sanitary. Choose four or five stages of filtration to ensure premium water taste and quality. The system comes ready to install with connection hardware, tubing, faucet and instruction manual.
The contract renews a five-year agreement with the FDA
Evoqua Water Technologies has been awarded a renewal contract to supply the U.S. Food & Drug Administration’s (FDA) Arkansas Regional Laboratory in Jefferson, Ark., with its ultra-pure laboratory deionized water system.
The success of FDA activities to protect public health often depends on the ability of its laboratories to quickly and accurately analyze samples. Ultra-pure water is key to accurate analysis and suggesting corrective action.
These water purifiers are housed in stylish grey ergonomic bodies. With their compact, rounded shapes, the purifiers are designed to be installed under a kitchen sink and allow easy filter changes and maintenance access. The small Cleone is a classic RO unit. The mid-sized Spirit has a contemporary style and delivers 43.2 gph of direct-flow water. The larger Bluewater Pro delivers 81.3 gph to professional users or those who want a whole-house water purification system.
The GRO RO membrane has a 50% recovery rate and maintains a retrofittable design. It comes in three models, with capacities of 36, 50 and 75 gpd. Each is certified to NSF/ANSI Standard 58 for materials and structural integrity, in addition to NSF list component performance claims. Its element design integrates a dry membrane to maximize lifespan and provide enhanced performance for the end user. It has high rejection stability at high input, and enhanced rejection performance.
Point-of-use (POU) reverse osmosis (RO) membranes often get a bad rap within the water treatment industry for a few reasons: It is a saturated, commoditized market with slimmer margins; there have been minimal technological advancements in system performance; they have a high percentage of wastewater to drinking water; and consumers are demanding greener, less wasteful products.
Changing customer needs lead to shifts in RO technology
The new high-performance GRO’s element design integrates a 100% dry membrane to help maximize its lifespan and provide enhanced performance to the end user. It also has a 50% recovery rate, while maintaining a retrofittable design for easy integration.
Applications for R14 Series RO systems for water purification in commercial settings include municipal water treatment, steam boiler and steam sterilizer make up, laboratory use, spot-free car washes, food processing, and metal plating & finishing, as well as water for humidification. The systems come in compact, wall-mounted version or in floor-mounted systems.
Mobile reverse osmosis system will provide clean water for 90 days
GE will commission a reverse osmosis (RO) mobile water filtration system at the Golden Valley Electric Assn. (GVEA) coal-fired power plant in Healy, Alaska. The GE system will provide the plant with clean water during a planned outage to upgrade the plant’s water treatment system and environmental controls and facilitate the startup of Unit 2. The total power output of the facility once Unit 2 is online will be 80 MW. The two-unit station is located approximately 300 miles south of the Arctic Circle.
R14 Series reverse osmosis (RO) systems for water purification in commercial settings are ideal for applications including municipal water treatment, steam boiler and steam sterilizer makeup, laboratory use, spot-free car washes, food processing, and metal plating and finishing, as well as for water for humidification.
The compact, wall-mounted, heavy-duty RO systems come in three models for flow rates up to 5,400 gal per day (gpd). They are available with brass or stainless steel fittings.
