  • Patent number: 7665546
    Abstract: A cleanout system and method for removal of metal debris from a fluid flow, such a flow of re-circulated drilling mud employs one or more magnetic unit positioned in the path of the fluid for collecting metal particles from the flow. The magnetic unit has a removable magnet core positioned in a non-magnetic sleeve. When the core is removed from the sleeve the attracted metal particles are allowed to drop from the sleeve under gravity to facilitate their collection and disposal. A fluid deflector is positioned upstream from each magnetic unit, protecting the magnetic unit from direct impact by the strong flow. The magnetic units are allowed to pivot from side-to-side and adjust their position in the flow.

  • Publication number: 20090223902
    Abstract: An integrated system for treatment of inorganic liquid waste is disclosed that quickly and efficiently processes large quantity batches of such liquid waste by initially removing solids and sludge and subsequently processing the liquid waste to remove other materials so that the processed liquid waste can be recycled in a conventional sewer system. Larger solids, sludge, and free phase oil are removed by the system before they enter the liquid waste processing equipment, thereby preventing damage to the processing equipment caused by these substances. The use of common liquid waste and sludge delivery lines on all of the contaminant removal reactors in the system facilitates the efficient operation of the system with a minimum of operator intervention being required.

  • Patent number: 7507343
    Abstract: The device of the invention includes the following 5 new elements in each mixer-settler: a) agitators with blunt edged turbines, b) decreasing degree of agitation throughout the series of mixing compartments, c) baffle with a central window in the settler interface, located after the flow buffers, and d) baffle without a window, centered in the settler interface, located after the baffle with a window. These elements allow for an operative method which inhibits secondary dispersion, reducing the formation of micro-droplets, without affecting the mass transfer between the phases. Consequently, this obtains a phase separation process with entrainments so small that it is possible to drastically increase the quality of the product, by obtaining an ultra-pure aqueous extract, simultaneously reducing the settling surface required.

  • Patent number: 7491333
    Abstract: A process for the treatment of industrial waste water. The process includes the steps of admixing partially-treated waste water containing precipitated impurities with a flocculating agent in a flocculation basin, directing the admixed waste water to an elongated sedimentation basin, allowing flocculated solids in the waste water to settle to the bottom of the sedimentation basin, removing the settled solids from the bottom of the sedimentation basin and directing the treated water from the sedimentation basin. The process can further include the step of adjusting the pH of the waste water to precipitate impurities in the waste water prior to the addition of the flocculation agent. The elongated sedimentation basin can include a pair of sloped sides to consolidate the settled solids at the bottom of the basin. The settled solids can then be removed by suction. The basins can be formed from the excavation or impoundment of earth in an area adjacent to a waste water-generating facility.
