Abstract
A method of paint sludge conversion and sludge removal from a sump pit for disposal is provided which is particularly adapted for use with paint waste sludge derived from wet spray booth operations. The method involves blending with the starting sludge caustic, oil and emulsifiers. Water may be added to achieve a desired water to total solids weight ratio. The product is a pumpable liquid disperse system which is easily charged to tankers or the like for pump out from the sludge pit.
