An agent for removing malodor from a painting booth includes a volatile organic compound (VOC) degrading microorganism and a volatile fatty acid (VFA) degrading microorganism. The VOC degrading microorganism is configured to degrade VOC. The VFA degrading microorganism is configured to degrade VFA generated when the VOC is degraded. A method of removing malodor is also disclosed.

The invention is a high-salt waste water air powered low temperature evaporating device and method of use. A tray is mounted on a lifting platform; an air inlet and a water inlet are on the tray. Air distributing pipes are arranged at the center of the nested column tubes (33). A groove (4) is installed at the top of the tray, and mounting points are accompanied by multiple nested column tubes (33). The nested column tubes (33) are connected with the air inlet. An atomizer is arranged inside the air distributing pipes; and the atomizer is connected with the water distributing pipes. Using air power evaporates concentrated waste water multiple times so that the salt in the wastewater reaches saturated concentration, and therefore, the wastewater temperature is reduced, salt is crystallized and separated out, liquid is continuously evaporated, and the wastewater can be completely treated.

A method for treating a wet-painting booth circulation water, includes, into somewhere along a path for a wet-painting booth circulation water supplied from a water tank to a painting booth for collecting an unapplied paint and then returned to the water tank, adding a treatment agent to a wet-painting booth circulation water so as to detackify the unapplied paint collected in the circulation water, wherein the treatment agent includes a cellulose acetate solution.

A method for degrading 5-chloro-2-methyl-4-isothiazolin-3-one in a liquid composition using dithio-2,2-bis(benzmethylamide).

A system for consolidating and removing contaminate such as paint sludge or oils from a fluid mixture. A contaminate tank receives a supply of the fluid mixture containing contaminate from a source such as a manufacturing line where overspray of paints or cleaning solutions containing washed away oils are collected. A free floating weir floats on the surface of the contaminate tank and mechanically separates and removes contaminate from a surface of the contaminate tank and concentrates contaminate in a consolidation tank. The free floating weir is equipped with several features that enhance the ability of the free floating weir to remove contaminate without becoming clogged.

The present disclosure provides stable, low chloride paint detackifier compositions. Also disclosed are methods of making the paint detackifier compositions and methods of using the paint detackifier compositions. The detakifier may be made from cationized starch and sodium aluminate. The starch can be wheat starch, corn starch, tapioca starch, potato starch, rice starch, sweet potato starch, sago starch, mung bean starch, arrowroot starch, and any combination thereof.

Fusion proteins containing a targeting sequence, an exosporium protein, or an exosporium protein fragment that targets the fusion protein to the exosporium of a Bacillus cereus family member are provided. Recombinant Bacillus cereus family members expressing such fusion proteins are also provided. Genetically inactivated Bacillus cereus family members and recombinant Bacillus cereus family members that overexpress exosporium proteins are also provided. Seeds coated with the recombinant Bacillus cereus family members and methods for using the recombinant Bacillus cereus family members (e.g., for stimulating plant growth) are also provided. Various modifications of the recombinant Bacillus cereus family members that express the fusion proteins are further provided. Fusion proteins comprising a spore coat protein and a protein or peptide of interest, recombinant bacteria that express such fusion proteins, seeds coated with such recombinant bacteria, and methods for using such recombinant bacteria (e.g., for stimulating plant growth) are also provided.

Described herein is an assembly, system and method for electrochemical destruction of perfluoro compounds such as PFOS, PFNA and PFOA, or other oxidizable or reducible compounds. Methods include flowing an aqueous liquid comprising a perfluoro compound into a vessel that houses a bipolar electrode assembly, the bipolar electrode assembly comprising a first electrode stack and second electrode stack, the first electrode stack comprising a first plurality of electrodes and the second electrode stack comprising a second plurality of electrodes, wherein the electrodes span laterally across at least a portion of the vessel, and wherein the electrodes define the boundaries of a tortuous path through the vessel; flowing the aqueous liquid through the vessel via the tortuous path; and applying a voltage to the bipolar electrode assembly while the aqueous liquid flows through the tortuous path to destroy the perfluoro compound.
