In-Depth Analysis of Changes Restores System Optimization

Significant changes to feedwater quality and/or pretreatment systems will have an impact on a membrane system.

BACKGROUND

A brackish water reverse osmosis (BWRO) plant had been operating effectively, applying Avista antiscalant and cleaners for about a year. Increased water production demand has led to the addition of new water resources and a higher recovery operation at the plant. The change in feedwater quality led to increased stress on the pretreatment system and rapid membrane fouling.

The existing membrane cleaning regime was reviewed to increase the time between cleans. Working with the site operator, Avista Technologies assisted in re-optimizing the cleaning.
