Electrodeionization Evaluation Program (EEP) Brochure (PDF 164 KB)

WHEN TO CONSIDER THE EVALUATION PROGRAM Low EDI Product Quality – pre-treatment is key to any EDI perform-ance. Our evaluation will find root causes for low product resistivity and poor ion rejection. Fouling Indicators – High stack elec-trical resistance and high pressure drop are fouling indicators. By recognizing all fouling indicators early on most EDI performance can be recovered with proper cleaning procedure. Mechanical Failure – System design and good engineering practices are important to any system. EDI leakage and oxidation of resin can irreversibly damage EDI systems if not detected early. Electrical Failure – Improper EDI stack isolation and system grounding could lead to stray voltage and amper-age leakage. Variability in Feed Source – Changes in feed water are not uncom-mon. It can affect overall system per-formance resulting in higher mainte-nance costs. USP Requirements – USP require-ments are annually updated. Many EDI Systems are in cGMP validated facili-ties. This require documented preven-tative maintenance (PM) programs and updated standard operating procedures (SOP). Need for Upgrade or Replace Ex-isting EDI – The product life cycle varies among EDI suppliers. The evaluation program will provide an objective recommendation for EDI replacement. CANDIDATES FOR EEP Reliability – Improve system reliability by an-ticipating and recognizing problems with your EDI system. Process Control – Improve water recovery and throughput understanding the limitations of your EDI system. Lower Costs – Reduce costs by reviewing the maintenance program in the pretreatment, affecting overall performance of downstream operations. BENEFITS Applied Water Solutions, Inc. P.O.

AWS provides data analysis, RO projections, staff training and documentation. AWS is an authorized service provider for all EDI brands, including earlier models, Ionpure, E-Cell, Elec-tropure, and others. Evaluation programs are independent from equipment manufacturers. Based on the evaluation we offer a stack replacement program for all models of EDI (CEDI). Our EEP program is part of our larger System Evaluation Program (SEP)sm, and Plant Evaluation Program (PEP)sm.
