In general the ion exchanger adsorbs ions counter to their ion exchange
The water then travels through a series of three selective ion exchange
resin vessels where the perchlorate is pulled from the water.
Reflecting the company's commitment to the cartridge exchange and mobile plant sectors, the new media conditioning centre is capable of regenerating all types of ion exchange
resin and a wide range of other media used throughout industry.
Clark Carlson, who was a Pacific Northwest senior research scientist at the time, says a number of different ion exchange
materials were tested for strontium removal capabilities.
Since the ion exchange
process takes place so fast, process parameters, such as superficial velocity, temperature and residence time, have negligible effect on the overall performance.
Our oral solid ion exchange
resin formulation has been shown to reduce or eliminate the choking hazard," stated Alitair President and CEO, William W.
The B-500 Ion Exchange
Tower is designed to be used in pairs as a "lead" tower and a "lag" tower.
Since that time researchers have evaluated ways to remove it, with biological treatment and ion exchange
systems investigated most often.
Novasep SAS (see IBO 10/31/04), which offers chromatography and crystallography solutions for pharmaceutical firms; Applexion, a maker of chromatography and ion exchange
for the food and biotech markets; and Orelis, which specializes in cross-flow filtration.
Although it would be more expensive to install a biological cleanup system to remove the perchlorate from the gallons of contaminated water than to implement an ion exchange
treatment system, the biological technique would be cheaper to operate over the long run, McLean said.
Arulanandan and Smith (8) studied the dielectric permittivity and conductivity of unspecified ion exchange
membranes in the range of [10.
Fortum has received a significant additional order from the American EnergySolutions for ion exchange
materials for purification of radioactive waters at the Fukushima Dai-ichi nuclear power plant in Japan.
