BWRO Plant – Cleaning Study

Finding a Stable Cleaning Regime

BACKGROUND

A brackish water reverse osmosis (BWRO) plant in eastern Spain suffered a significant loss of performance, with permeate flow rate dropping 40% and a consequent drop in recovery from 65% to 45%.

After unsuccessful cleaning attempts, Avista™ was approached to help the client remediate the system and to find a stable operating regime. This case study outlines how Avista was able to assist and provides data on the resulting successful cleaning and operating regime.

Prior to Avista becoming involved, generic chemicals and products from another specialist company had been applied without success.

Avista proposed off-site cleaning trials to determine the most effective cleaning regime.

Download our full case study to find out how off-site membrane test cleaning identifies the most effective cleaning regime and cuts down on-site testing cost and time. For systems that have been fouled far beyond the recommended membrane manufacturers’ limits, Avista™ formulated cleaners can provide effective recovery back to design levels.
