SWI industrial-sized seawater RO systems have capacities ranging from 8,000 to 500,000 gpd. They feature duplex stainless steel multistage high-pressure pumps, FRP membrane housings, 8-in. TFC membranes, a non-corrosive prefilter and an advanced PLC-based control panel with touch screen, all mounted on a powder-coated steel frame that supports all instruments, piping and valves. Custom-made systems are available.
A wide range of research and development is being conducted to solve the challenges of providing clean water, with a significant emphasis on drinking water. The research focus has included advanced membrane technology; changing water chemistry to suit the remediation technology of choice; and media modification for increased selectivity, activity and capacity.
The purpose of this study is to focus on sorptive media modification for improved performance.
Treatment media advancements through application of nano-science
Today, beverage production facilities make a wide range of products, including carbonated soft drinks, energy drinks, juices, teas and purified drinking water. The number one ingredient in all of these products is water. Naturally, the quality of the water, as well as the operation of the water treatment system, are key to the quality and profitability of the facility.
Ultra-low-energy RO membranes help beverage facilities save energy and costs
Axeon CRO Reverse Osmosis Systems feature a sleek, ultra-compact design manufactured for residential applications and for feedwaters up to 1,000 total dissolved solids (TDS). The systems utilize a single-cartridge design, which allows for high-flow membrane performance. The large-diameter tubing of the CRO systems provides a 30% faster flow rate from the faucet. The unique flow path of these systems can reduce water waste by 50%, resulting in more water to the tank and less water down the drain.
Fractional electrodeionization and ultrafiltration membranes featured at booth #1150
QUA, a developer of advanced membrane products for water and wastewater treatment applications, will showcase two high performance membrane products – FEDI fractional electrodionization and Q-SEP hollow-fiber ultrafiltration (UF) modules – at booth #1150 at WQA Aquatech USA 2012.
R2 and M2-Series RO systems are engineered and manufactured for commercial and light industrial applications and for feed waters up to 10,000 TDS. These high-efficiency systems use low-energy membrane elements that deliver high quality water at low operating pressures. This in turn makes AXEON R2 and M2-Series the first low-energy brackish water systems in the marketplace.
American Water and Drexel University will partner for study
American Water Works Co. Inc. announced that it received a grant from the WateReuse Research Foundation to conduct a joint research project with Drexel University to measure and reduce biological fouling on membrane filters in desalination applications. The project is titled, "Application of the Bioluminescent Saltwater Assimilable Organic Carbon (AOC) Test as a Tool for Identifying and Reducing Reverse-Osmosis (RO) Membrane Fouling in Desalination."
Flexeon AT, BT, CT, DT and GT series reverse osmosis systems are engineered, manufactured and factory-tested to provide an affordable, high-quality solution for commercial and industrial applications. These high-efficiency low-energy systems use Axeon membrane elements that deliver high-quality water at low operating pressures.
The Palm Spring water dispenser comes equipped with a five-stage reverse osmosis (RO) system suitable for places with a greater demand of drinking water such as meeting or convention rooms. The dispenser is available in cold, hot and room temperatures and can also dispense soda water. Options include an ultraviolet (UV) and direct chill system.
This is the first in a series of five articles providing an overview of how point-of-use (POU) reverse osmosis (RO) technology works in residential systems and the critical parameters to keep in mind to optimize its performance.
