Electrodeionisation System

Electrodeionisation System employs EDI technology to produce high purity water. EDI process systems replace conventional Dl mixed bed resins unit to produce deionised water. Indu Associates EDI does not require shutdowns to regenerate the resins with chemicals or replacing resins. Consistent high purity Ultrapure water having resistivity of 12-15 Mohm.cm can be produced.

Reverse Osmosis followed by Electrodeionisation System and then by ultrafiltration or another stage of RO complies with USP requirement meeting the specifications for the final Rinse of primary conditioning and for non-sterile production of ointments, Liquid and Tablets. Complete unit is mounted on a single stainless steel skid. Hot water sanitizable models that shorten the time necessary for sanitization of the RO and Electrodeionisation System and Eliminates need of messy chemicals. RO-EDI is the safest and most reliable chemical free process to produce Purified Water and is well proven.

Hot water sanitization is a perfect solution to prevent microorganism growth and biofilm development without utilizing unacceptable biocide chemical. Two pass RO system with intermediate Electrodeionisation System or RO-EDI with final stage of UF are also an option.

Ultra Filtration (UF) is used for final rinse to remove pyrogens (bacterial endotoxins) from water. The UF membrane has a mol. wt. Cutoff on 10000 Dalton.
