  • Publication number: 20090001026
    Abstract: A paint reclamation clarifier system in communication with a sump tank in a paint booth containing a carrier fluid for capturing paint droplets and a conduit for transporting the carrier fluid mixed with paint droplets to the reclamation clarifier system is presented. The clarifier system includes an influent port, a detackification agent inlet, a sludge tank in a lower portion of the clarifier for collecting the dispersed carrier liquid, where the paint droplets bond with the agent and settle to the bottom of the sludge tank, a sludge outlet, and, at least one effluent port located on or near an upper portion of a sidewall of the clarifier system permitting unsettled material to exit from the clarifier.

  • Publication number: 20030177902
    Abstract: A system and process for industrial painting operations is disclosed. The disclosed system and process includes entraining paint particles from a paint booth operation in a stream of air; directing the stream of air to an aqueous bath covered with a layer of small silica particles; encapsulating the paint particles present in the stream of air with the small silica particles; further cleansing the stream of air by removing residual paint particles and other unwanted compounds as the stream of air is directed through an exhaust system; and recycling the encapsulated paint particles remaining in the paint booth.

  • Patent number: 5702516
    Abstract: A method of using water soluble foamed starch for reclaiming paint overspray particles from air includes the steps of passing a stream of air containing paint overspray particles through an air filter assembly having a filtration element. The filtration element consists essentially of water soluble foamed starch. The paint overspray particles are collected on the filtration element. The filtration element containing the collected paint overspray particles is deposited in a vessel containing water. The filtration element is dissolved in the water and an aqueous solution of starch in water is formed. The paint overspray particles are separated from the aqueous solution of starch dissolved in water.

  • Patent number: 5684053
    Abstract: A process for recovering paint overspray particles includes segregating the paint overspray by color and type, and detackifying, dewatering, drying and particulizing the dried, dewatered, detackified, segregated paint overspray compounds. The resultant compounds is used as paint additive.

  • Patent number: 5092928
    Abstract: A process for recovering paint overspray particles includes bringing the paint particles into contact with a plurality of hydrophobic fumed silica particles and encapsulating the paint particles within a plurality of the silica particles. The recovered encapsulated particles may be mixed with a suitable solvent, milled and blended with preselected additive materials, to form a desirable reconstituted paint material.
