Reclamation’s funding will support almost $13.5 million in research
The Bureau of Reclamation selected nine projects to receive $1.49 million under its Desalination and Water Purification Research Program. Reclamation’s funding will support almost $13.5 million in research.
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.
The event will be held in San Diego, Aug. 30 to Sept. 4
The 2015 International Desalination Assn. (IDA) World Congress on Desalination and Water Reuse will take place in San Diego, Aug. 30 to Sept. 4, at the San Diego Convention Center.
In today’s marketplace, there is a growing demand for higher production rates from RO membranes. Many light commercial applications require high water output, which standard thin-film membranes have not been able to treat. Many tap water reverse osmosis membrane elements were initially designed to achieve specified flow and rejection rates under only 15% recovery, thus dispensing a lot of water to the drain.
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.
To accommodate the growing demand in commercial water treatment of tap water and well water, Axeon Water Technologies has announced the redesign and expansion of the R1-Series commercial reverse osmosis systems.
Point-of-use reverse osmosis element design, specifically the distribution of feed water to the membrane, has remained somewhat static since the introduction of thin layer/film composite (TLC) or non-cellulose membranes. Most reverse osmosis systems, depending on design and operating conditions, dispense 70 to 90% of feed water to the drain. Many RO systems use a similar membrane and distribute water through the element in the same manner, so there is little opportunity to increase the system’s efficiency.
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.
