New York senior wins Patrick H. Hurd Sustainability Award for project in Kenya
A Dix Hills, New York, high school senior has won the U.S. Environmental Protection Agency’s Patrick H. Hurd Sustainability Award for a project currently providing clean drinking water affordably to a community in Kenya.
Webcast will occur on Feb. 17
Dow Water Academy will host a free webinar on Wednesday, Feb. 17, at 3 p.m. (CST). The webinar will explore the concept and theory behind direct-coupled ultrafiltration/reverse osmosis, as well as share best practices, recommendations and case study examples. Those interested may register here.
The booklet is second in a series of educational publications
The Water Quality Assn.
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.
