    摘要: The invention provides an improved method for dewatering coal tailing aqueous slurries in a twin belt press process. The method including the step of adding to the slurry a high molecular weight anionic flocculant followed by a coagulant containing vinylamine. The flocculated coal is then mechanically dewatered using a twin belt press.

    摘要: A chemical treatment process and separation module are described for removal of soluble organic compounds and suspended or emulsified oils and/or solids from produced waters that accompany operations for oil and gas recovery. The process occurs in its entirety within an interval of several minutes. The solubility of organic compounds is first reduced, in an optional step, by pH reduction, followed by treatment with coagulants and flocculants, the latter in conjunction with microbubble flotation. The organic compounds that are rendered insoluble, along with other oily solids, are captured in the floe created by the coagulant and flocculant treatment, and simultaneously made buoyant by the concurrent addition of microbubbles. The water and floe is passed over an array of sloped strainers that separates and diverts the floe from the effluent water, which contains significantly reduced soluble organic content. The separated stream of oily solids can be dewatered for disposal as waste.

    摘要: The removal of oils, fats, and proteins from various industrial process streams containing these materials; such as dairy, cheese, whey, meat, fish, and vegetable process streams is accomplished by adding a mixture of sulfuric or phosphoric acid with calcium or magnesium phosphate or sulfate to the waste water to adjust the pH of the waste water to less than 7; and then separating the resulting solids from the liquid in the waste water; and adjusting the pH of the solids and liquid to make them acceptable waste products having a pH of 6-9.
