Incorporating a number of ion exchange beds mounted on a rotating carousel, the ISEP continuous ion exchange system is offered to eliminate nitrate problems Newsletter Signup Get the latest water industry news, insights, and analysis delivered to your inbox.
• Continuous ion exchange systems (e.g., a carousel of vessels, some in service, some in regeneration) Figure 1 provides a visual comparison of the service and regeneration modes for co-flow, counter-flow and split-flow counter-flow vessel designs and the impact these have on the reduction of wastewater volumes.
A column carousel system was designed to treat nuclear waste at the Savannah River Site. A carousel model was used to simulate cesium removal in an ion-exchange carousel loaded with crystalline silicotitanate (CST) granules. The model accounts for axial dispersion and resistance to film and intraparticle diffusion.
REKON Ion Exchange Wastewater Recovery KONTEK REKON Systems are implemented for rinse water recovery and purification in applications where trace heavy metals and salt contaminants must be removed. The liquid waste volume produced by the regeneration cycle is typically 3% of the total volume of of recycled water.
A design method based on the standing wave analysis for unfavorable isotherm systems has been developed in this study to ensure high product purity and …
The entire device has a structure that resembles a "carousel", and is therefore referred to as a carousel-type ion exchange equipment [29], [30]. In recent years, researchers have been continuously exploring and improving the structure and operating principles of continuous ion exchange equipment in to enhance its efficiency, …

A systematic model-based approach is used for development of an efficient carousel ion-exchange process for the selective removal of radioactive {sup 137}Cs{sup +} from alkaline nuclear waste solutions. Equilibrium data for two resorcinol-formaledhyde (R-F) cation-exchange resins are correlated by an empirical equation of the Freundlich ...
Ion exchange is a powerful technology to soften and demineralise water to extremely good quality. This technology is well proven, as it developed initially in the 1950s, and today, it is still the best to produce ultra-pure water, i.e. to remove all traces of contaminants. In addition to water treatment, ion exchange is also used in a variety ...
Getting Started. First, update to the latest version of Ionic: npm install @ionic/angular@latest. Once that is done, install the Swiper dependency in your project: npm install swiper@latest. Next, we need to add the CUSTOM_ELEMENTS_SCHEMA, which tells Angular that we will be using custom elements.
Instead of using a carousel to move the cells around the valve, the process disc within the ION-IX multiport valve rotates around and distributes the different streams to the cells containing ion exchange resin or other …
fraction collector arm. Note: To rotate the carousel, reach around the left side of the collector to find a rubber roller pressing against the carousel (Fig 2). Pull the roller away from the carousel (Fig. 3); the carousel will rotate freely as long as the roller is held. When the first tube is in the correct position, release the roller. 9.4.10.
A column carousel system was designed to treat nuclear waste at the Savannah River Site. A carousel model was used to simulate cesium removal in an ion-exchange carousel loaded with crystalline ...
Calgon Carbon's ISEP ® /CSEP ® ion exchange technology is used by many food and beverage processors for purification, decolorization, separation and deashing. Our …
Other continuous countercurrent ion exchange systems use a carousel to rotate the resin cells around a central valve. This approach again offers some advantages, but also …
Ion exchange (IX) systems are used across a variety of industries for water softening, purification, and separation purposes. While the chemistry of individual ion exchange reactions varies from one application to the next, IX is a treatment process where dissolved ions are replaced by other, more desirable, ions of a similar electrical charge.
The design procedures for various periodic processes of ion exchange have been discussed in several publications concerning a batch system based on a single column operating periodically (Sun et al., 1990, Lewus et al., 1998, Castel et al., 2000) as well as a continuous system utilizing multicolumn setups such as the carousel system …
A three-column carousel process based on a pelletized form of CST powder was designed to remove radioactive 137 Cs + from SRS nuclear wastes. A multicomponent ion-exchange equilibrium model was used to generate cesium loading data, which were fit to the Langmuir equation to obtain effective single-component cesium isotherm …
A systematic model-based approach is used for development of an efficient carousel ion-exchange process for the selective removal of radioactive Cs-137(+) from alkaline nuclear waste solutions. Equilibrium data for two resorcinol-formaldehyde (R-F) cation-exchange resins are correlated by an empirical equation of the Freundlich-Langmuir type ...
A carousel model was used to simulate cesium removal in an ion-exchange carousel loaded with crystalline silicotitanate (CST) granules. The model accounts for axial dispersion and resistance to ...
A three-column carousel process based on a pelletized form of CST powder was designed to remove radioactive 137Cs+ from SRS nuclear wastes. A multicomponent ion-exchange equilibrium model was used ...
In this work, the continuous multi-column lithium extraction process is designed based on carousel-type continuous ion exchange equipment, and a multi …
It is shown that ion-exchange sorbents based on phenol-formaldehyde resins can be used for a long time for isolating and separating rare alkali metals without any significant changes in the ion-exchange selectivity and capacity. When the phenol sorbents were used in alkaline solutions at elevated temperatures, carboxyl groups gradually …

This article reviews the historical uses of and current research into ion exchange for the removal of cesium from defense-related nuclear waste streams. Emphasis is placed on key attributes of the two current leading ion exchangers for Cs removal: spherical resorcinol-formaldehyde, an elutable organic resin, and crystalline …
An equilibrium multicomponent ion exchange model is presented for the ion exchange of group I metals by TAM-5, a hydrous crystalline silicotitanate. On the basis of the data from ion exchange and structure studies, the solid phase is represented as Na3X instead of the usual form of NaX. By using this solid phase representation, the solid can …
