  • An electrostatic shielding-based coupled electrodialysis/electrodeionization process for removal of cobalt ions from aqueous solutions

    Electrode graphite powder beds were interposed between anode and cathode as intermediate electrodes inside an electrolytic setup. Due to electrostatic shielding they eliminate the applied electric field and therefore stop the electromigration of ions within their mass. It was found that the intermediate electrodes can act as ionic current sinks—ion concentrating compartments and therefore cause a ...

  • Sohar Refinery

    Project Background Orpic (Oman Oil Refineries and Petroleum Industries Company) required a thermal seawater desalination solution as part of its Sohar refinery improvement project to ensure an uninterrupted supply of fresh feed water to for its boilers. ...

  • TB 72: Chinese chemical plant optimizes water treatment by replacing double pass ro with a single pass ro and liqui-cel® contactor system

    Electrodeionization (EDI) is widely used in many industrial water treatment systems throughout the world. In order to maximize the operating stability and life expectancy of an EDI system they were often designed with double pass RO using caustic injection pretreatment. However, in response to recent efforts to lower the capital expenditure and operating costs of double pass RO water treatment ...

  • Add polish to high purity water

    Electrodeionization (EDI) has recently gained widespread acceptance by water treatment companies and end users alike for almost all applications requiring high-purity water. EDI has proven to be a reliable, cost-effective solution for both end users and water treatment companies. End users purchasing capital equipment can eliminate on-site chemical regeneration. Water treatment companies selling ...
