Portable Exchange Deionization (PEDI) provides flexible configurations and rapid deployment of ion exchange systems without the need to handle potentially dangerous chemicals or to deal with acidic and basic regeneration wastewaters. Portable exchange can be used for selective removal of targeted contaminants as well as for bulk deionization and polishing the effluent from other treatment processes. Suzhou X Chemical manufactures a wide variety of mixed bed and separate component resins specifically for the portable exchange industry. They are available regenerated (ready to use) and in exhausted forms (suitable for long term storage). Ion exchange resins for portable exchange use are available in high purity and low TOC versions suitable for pharmaceutical and semi-conductor applications.
