REVIEW

Avista® Technologies was contacted by a municipal water supplier in Ohio USA in June of 2012 to seek advice on their reverse osmosis (RO) system which had been experiencing increases in delta pressure and flow losses in a matter of days. 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, left). Maintaining the integrity of the RO performance proved difficult due to the continuous scaling condition present on the tail end of the RO system.
