ABSTRACT:
A fluid wash spray paint system which includes a plurality of paint spray booths is provided. Each paint spray booth includes a fluid wash device to entrap paint overspray in a moving fluid to remove the overspray from the booth. The system also includes a sludge pit for collecting the fluid and entrapped paint overspray from the plurality of spray booths. An automatic feeder is provided to introduce a deflocculant powder into the fluid and entrapped paint overspray to cause the paint to settle as sludge to the bottom of the sludge pit. A centrifugal separator is provided to separate and remove the settled sludge from the fluid and to return the fluid to the sludge pit. The system further includes a pump to circulate the fluid from the sludge pit through the plurality of fluid wash spray devices to form a closed system.
