For process solutions requiring minimal chemicals, we can offer our customers a selection of EDI technologies including our inhouse SEPTRON® spiral wound modulesand/or other proprietary designs from ECELL® and IONPURE®.These systems are usually coupled with single or twin pass RO systems to provide a fully integrated 'Plug and Play' solution.This solution may suit customers that are adverse to handling hazardous chemicals and require a clean and compact treatment plant. Fully containerised plants are available.For the production of ultrapure water a combined RO/EDI plant is usually considered for flowrates below 50m³/hr.
