3D TRASAR Technology Protects Membranes from Chlorine

Mar 31, 2014

A Nalco customer in North America is an OEM parts supplier for the automotive industry. Process water is produced by Reverse Osmosis (RO) in this plant. A predetermined amount of SBS is added to the RO feed water to control free chlorine. The free chlorine was measured periodically and was therefore deemed to be in control. The RO system was run at particularly low levels at ~60% recovery to obtain a stable water production. When 3D TRASAR Technology and Nalco 360 Service were combined with a regular maintenance and calibration of the system, ORP excursion could be controlled seamlessly. As a result, Nalco protected $10,600 worth of membranes from being damaged by chlorine.
