Abstract: A method and system for treating waste water from hydraulic fracturing is disclosed. The treatment includes removing the sand, suspending the inorganic metals and impurities, using flocculation to engulf the impurities, and separating the impurities from the water, resulting in pure water that can be reused in the process.

Abstract: The present invention is directed to improved thermoplastic compositions which possess, when utilized for plenum cable construction, not only enhanced low flame and smoke properties, but also enhanced physical properties, such as tensile strength, elongation retention, high and low temperature stability, etc. The thermoplastic compositions may be utilized in various embodiments for producing both the insulation and jacketing layers of plenum cables. In addition, the present invention is also directed to the insulated wire and the jacketed electrical cable produced utilizing the improved thermoplastic compositions.

Abstract: The present invention relates to a process for substantially inhibiting polymer build-up on reactor surfaces during polymerization. The method generally comprises the application of a polyaniline coating composition to the reactor surfaces in contact with the reaction medium prior to charging the reactor and the carrying out of the polymerization reaction. The polyaniline coating composition broadly consists of about 0.01 to about 20% by weight of deprotonated polyaniline, such as polyaniline in the pernigraniline oxidation state, dissolved in an organic solvent carrier, such as dimethyl sulfoxide (DMSO), 1-methyl-2-pyrrolidinone (NMP), acetic acid, sulfuric acid, formic acid and tetrahydrofuran (THF).
