operating procedures. If these conservation options appear to be
applicable to your operation, it is still highly recommended that
you periodically check your operations to insure that the
equipment is still operating within the manufacturer's
recommendations.
a)
For paint spray booths:
(1) Reduce the flow of the water to minimum
levels that will still catch the airborne paint.
(2) Re-circulate the water more times through the
booth before replacing it.
b)
For paint stripping facilities:
(1) Squeegee off used stripper and loose paint
instead of flushing with water in spray rinsing applications.
(2)
Repair leaks in rinse tank connections.
(3) For rinse tanks, many of the water
conservation measures used in plating facilities can be applied.

Replacements
a) Paint spraying booths. For paint spraying booths,
the wet spray booth can be replaced with a dry spray booth. A
dry booth uses filters instead of water to extract airborne paint
particles from the atmosphere and exhausts any solvent fumes as
well. This system eliminates the generation of wastewater that
must be treated on-site or disposed of as hazardous waste. The
filters are simply exchanged when they become fouled. However,
the dry filters, contaminated with paint, are also likely to
require handling as hazardous waste. Dry spray booths are
relatively low in cost and easy to install. Figure 15
illustrates two types of spray booths must be treated on-site or
disposed of as hazardous waste. The filters are simply exchanged
when they become fouled. However, the dry filters, contaminated
with paint, are also likely to require handling as hazardous
waste. Dry spray booths are relatively low in cost and easy to
install. Figure 15 illustrates two types of spray booths.
Another option for painting smaller parts is to replace
the traditional liquid coatings with powder coatings. Powder
coatings are attracted and attached to the workpiece surface in
