Background Information

The RRC, a Microsoft Access 2002 database, is used to determine the amount of water needed to maintain the levels and concentrations of single, double counter-current (DCCR) and/or triple counter-current rinse (TCCR) tanks. It was developed to support rinsewater reduction efforts, specific to tankline operations, at the Boeing Company and first introduced to the public at AESF Week 2004, by John Fullen and Julie Unangst.

The RRC is designed for applications where a timer is used to control the addition of water to a rinse tank. Settings obtained from the RRC (sec/load or min/load) are used to program the timers, and tankline operators are trained to press the timer button each time a load is processed. Strictly controlling the amount of water added to the rinse tanks in this manner results in more efficient rinsewater management.

Additionally, the RRC can be used to compare the efficiencies of the single rinse, DCCR and TCCR. The impact of process parameters on water usage can also be evaluated (e.g., rinse temperature, loads per day, air agitation level, water quality, etc.).

The foundation of the RRC consists of mathematical models, which were developed for a single rinse, DCCR and TCCR. These models were developed by performing a mass balance around each of the rinse systems, taking in to account incoming and outgoing streams, such as process solution dragin, rinsewater dragout and evaporative losses. The RRC adapts the mathematical models for use in production applications.
