Significance and Use

The design of an electrodialysis/electrodialysis reversal system is determined by the composition of the feedwater and the desired composition of the product water. The determinations and measurements performed in this guide will provide the necessary information for making design projections of staging and power consumption.

The recovery at which an electrodialysis/electrodialysis reversal system can be safely operated is dependent on the composition of the feed solution. The determinations measurements performed in this guide will provide data for the calculation of the maximum recovery of a system utilizing a specific feed water.

The determinations and measurements performed in this guide will be valuable for determining needed pretreatment for meeting specific product water requirements with the specific feed water.

1. Scope

1.1 This guide covers the determinations that should be performed on any given water if processing by electrodialysis/electrodialysis reversal is being considered.

1.2 This guide is applicable to all waters but is not necessarily complete for wastewaters.

1.3 This is a guide only and should not be construed as a complete delineation of all analysis required for a specific application.

1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

2. Referenced Documents (purchase separately) The documents listed below are referenced within the subject standard but are not provided as part of the standard.
