initial capital cost of installing a recycling system can range
from approximately K to several hundred thousand, depending on
the technology employed.
5.3.1.2
Operation and Maintenance Procedures. The following
maintenance procedures can help conserve washrack water use:
a) A periodic check of equipment for malfunctions or
leaks is a simple but effective way to conserve washrack water.
b) If detergents are used, use high quality detergents
with superior cleaning power. This, combined with good
rinsability, will shorten the length of time required to clean
each vehicle or aircraft.
5.3.1.3
Retrofits. For existing wash facility equipment, there
are several low cost measures that are capable of saving
significant amounts of water.
a) Timers - useful in aircraft rinsing facilities, but
not for washrack units since each vehicle or aircraft must be
washed until sufficiently clean. The timing is different for
each run and should not be preset.
