The accumulation of deposits in the secondary side of steam generators (SGs) increases the potential for accelerated tube degradation and flow oscillations. As these deposits harden and form crevices, they can cause conditions that lead to tube corrosion. To improve upon traditional mechanical deposit removal techniques and avoid the potential drawbacks of traditional SG chemical cleaning, advanced scale conditioning agent (ASCA) technology was developed in 2000.

The mobile reverse osmosis (RO) system was developed to address waste reduction following advanced scale conditioning agent (ASCA) applications. Coupling Westinghouse RO waste reduction with ASCA applications allows customers to meet their steam generator cleaning and waste reduction needs through a single service provider.
