  • Patent number: 9192879
    Abstract: The system and method is directed to improved separation or clarification of solids from a solids-laden liquid, including the removal of low gravity solids. A liquid to be treated is introduced into the inlet of a solid-liquid separator modified to include one or more sources of vibrational energy. The liquid is directed through a conduit within the separator. This conduit can be configured into a tortuous flow path to assist in the separation of solids from the liquid, the tortuous path being interconnected between two separation towers. Vibrational energy and gas sparging is applied to the flow path. As solids fall out of solution, they are collected. The clarified liquid is also collected. A vacuum can be applied to the system to assist in moving the solid-liquid mixture through the system and to provide vacuum clarification. Electrocoagulation electrodes can also be employed.

    Abstract: Some waters have high sulfate contents, such as acid mine drainage (AMD), which makes them unsuitable for use in fracturing fluids and difficult to dispose. Such waters may be treated with a solution of barium chloride to react with the sulfate ion of the sulfates and precipitate the sulfates as barium sulfate. Not all of the sulfates needs to be removed for the reclaimed water to be useful in formulating a fracturing fluid. The by-product of the reaction is almost pure barium sulfate, which is an inert, commercially valuable material that may be used in drilling fluids, paint and other industries.

  • Patent number: 8968569
    Abstract: A method of wastewater reutilization by which reusable water can be stably obtained from a wastewater. Ozone is added to a wastewater, such as water resulting from sewage treatment, in such a small amount as to result in a residual ozone concentration as measured before membrane filtration of 0.01-1.0 mg/L. Ozone is thus brought into contact with fine solids contained in the wastewater to alter the surface properties of the fine solids so that the solids are easily to coagulate. Thereafter, a coagulant, e.g., PACl, is added from a coagulant addition device (3). The fine solids are coagulated in a coagulation tank (5) or a line mixer and the resultant water is subjected to membrane filtration with an ozone-resistant separation membrane (6) such as ceramic membrane. Thus, reusable water is obtained which has a residual ozone concentration, as measured after filtration through the membrane, less than 0.5 mg/L.

The blood reservoir has a serum producing function to remove coagulation factors from the blood to an extent enabling use in practical applications as a serum, and the component storage part stores each blood component generated by separation of the blood in the blood reservoir.

  • Publication number: 20140299551
    Abstract: A desalination system comprises an electrodialysis reversal apparatus configured to receive a first stream for desalination and a second stream to carry away ions removed from the first stream, and a precipitation unit in fluid communication with the electrodialysis reversal apparatus and configured to circulate the second stream therebetween. At least one backwashable filter is disposed between and in fluid communication with the electrodialysis reversal apparatus and the precipitation and configured to filter the second stream in a normal operation mode. A desalination method is also presented.

  • Publication number: 20140263081
    Abstract: This invention relates to the field of water purification and desalination. In particular, embodiments of the invention relate to systems and methods of removing essentially all of a broad spectrum of impurities from water in an automated industrial process that requires minimal cleaning or maintenance during the course of several months to several years, with relatively high yields of product water per unit of input water, flexibility with respect to energy sources, compact design with a low industrial foot-print, the ability to recover valuable by-products, and ultra-low energy requirements.

  • Publication number: 20140263044
    Abstract: A solid dissolver system for the treatment of waste material in a waste water collection system. The solid dissolver system includes a housing. The housing includes a cover and a platform portion for receiving the cover. A cartridge containing agents for the treatment of waste material is disposed within the cover, the cover substantially surrounding and enveloping the cartridge, the cover including an opening. A water inlet is provided into the housing, the water inlet terminating at a spray means disposed proximate to or inside the cover opening, the spray means being capable of directing water at an exposed surface of the cartridge, the platform portion being capable of collecting any effluent from the water directed at the exposed surface of the cartridge by the spray means. A water outlet for channeling the effluent into a waste water collection system is included in the platform portion.

  • Patent number: 8834726
    Abstract: A method of treating a wastewater is provided and can be used, for example, to treat a gas well hydrofracture wastewater. The method can involve precipitating barium as barium sulfate, precipitating calcium and strontium as calcium carbonate and strontium carbonate, precipitating magnesium hydroxide, and filtering out the metal compounds to form a recycle water. The recycle water produced from the method is also provided, as is a method for using the recycle water as a gas well hydrofracture water. In some embodiments, discharge water from a coal mine, and/or water from an abandoned coal mine, is used as a source of sulfate ions to precipitate barium as barium sulfate.
