Abstract
The present invention includes a composition having detackifying and detoxifying properties such that the composition is useful for detackifying and detoxifying paint particles in spray booth water and for treating a paint booth dry filter to render the filter fire retardant, non-combustible and non-hazardous to enable disposal of a used dry filter in a standard landfill. The present invention also includes a method for the detackification and detoxification of oversprayed paint in a paint spray booth system wherein said oversprayed paint comes into contact with water of a waste water system.
Claims22
A method for detoxification of a paint booth dry filter having paint thereon, comprising the steps of:
- providing a composition having detackification, detoxification and neutralization of combustibility properties, the composition comprising an aqueous mixture having a pH in a range of from about 7.5 to about 9 and containing an effective minor amount of cationic polymer having a molecular weight of at least about 7.5 million such that the composition is useful for detackifying and detoxifying paint particles in spray booth water;
- mixing the composition with filter soak water to provide a resultant mixture having a composition:water ratio in a range of from about 1:5 to about 1:10;
- and
- soaking the paint booth dry filter having paint thereon in the resultant mixture for a period of time effective to detoxify and remove paint present on the paint booth dry filter.
