Improve System Performance

Case Studies
November 18, 2020

BACKGROUND
Avista™ was contacted by a municipal water supplier in Ohio, USA, for advice on their reverse osmosis (RO) system which had been experiencing increases in delta pressure and flow losses in a matter of days.

Maintaining the integrity of the RO performance proved difficult due to the continuous scaling condition present on the tail end of the RO system.

 

 

SYSTEM DESCRIPTION
The RO process has a well water feed producing approximately 300 gpm of drinking water for the city. The water treatment plant was experiencing a heavy buildup of scale on the RO plant’s concentrate lines and transfer wells (see Figure 2).

Maintaining the integrity of the RO performance proved difficult due to the continuous scaling condition present on the tail end of the RO system.

Feed water: Well water

Application: Municipal

ACTION/APPROACH
Our applications specialist went to the site and conducted a system audit. After the audit, a tail element from the second stage was removed.
