Process Water Energy Strategy


Medical device, Pharmaceutical, Food & Beverage and Manufacturing companies demand large quantities of water to produce high purity water. A more practical approach to reduce water usage is the development of efficient and effective water consumption program.

A water consumption program is broadly divided into two Key categories: Efficient and Effective Process plant Operation and Design, based on a review from the End to the Start of the process water plant.

Efficiency is a measure of the percentage of the total energy based on the water usage, so that it makes sense to optimise the operational parameters of the plant. Thus reducing the energy requirements for optimized plant performance.

Effectiveness is measured in terms of being able to remove the contaminants that are present in the water, and the ability to detect any abnormality in the fastest possible time. An effective system is also reliable and operates in such a manner that prevents contaminant concentration.

Approach to the Process Water System Energy Strategy.

Phase 1 Review of Plan

  • Mapping of water consumption in real time.
  • Analysis of energy needs associated with Process Water Technology
  • Identification of focus area’s work groups on the Key area’s

Phase 2 Analysis

  • Analysis of Cost associated with energy requirement.
  • Optimisation of Process water usage technologies through parameter and set-point review.

Phase 3 Follow up

  • Evaluation and implementation of savings initiatives

Challenges: Raw water Quality supply variations is one of the biggest challenges in the operation of a Process water system. Real time records monitor the Water Quality chemistry variations which are critical in determining the challenges to the performance of a system.

One thought on “Joe Dunning

  1. Fully agree Joe. Too many water management strategies are limited to simply monitoring and tracking of water usage and flows…. whereas all the international standards and best practice in this area highlight the importance of both quantity and quality parameters. That is the key challenge … something that is core to the EUs Water Blueprint Policy Document.
