BACKGROUND
A consulting engineering firm, selected to design and oversee the construction of a 5MGD reverse osmosis (RO) system for a Southern California military facility, handed over the system to an operations management firm. Upon handover, the original OEM of the system recommended that the management firm contact Avista™ Technologies for support with analytical membrane services, antiscalant recommendations, and on-site technical training for the operators. Avista received the call and was on site the same day to evaluate the system.

 

SYSTEM DESCRIPTION
Once on site, an Avista application expert provided a technical audit of the system evaluating operating conditions including pressure, flows, and conductivities. The system standard operating procedures and historical operating data were reviewed as were the chemical membrane compatibility standards. As a part of the system audit, membranes from first and second stage were pulled and evaluated under manufacturer specs, using the Avista Off-site Cleaning and Restoration (OSCAR) system. This in-depth audit identified that the system had minor membrane fouling. A complete membrane autopsy was recommended, which identified the specific foulant and appropriate cleaning chemicals and procedures.
