    Abstract: A method for treating wastewater containing TMAH and ammonium nitrogen includes the steps of (a) introducing a first solution which contains ammonium nitrogen but no TMAH into a single reactor with microorganisms comprising nitrifying bacteria and anammox bacteria, and denitrifying the first solution by the microorganisms under a dissolved oxygen concentration ranging from 0.1-0.5 mg/L and a pH value of 7-8; (b) when the denitrification efficiency reaches a steady state, introducing a second solution which contains ammonium nitrogen and TMAH and has a concentration of TMAH lower than 60 mg/L into the reactor; and (c) gradually increasing the concentration of TMAH in the solution to be added into the reactor for several times whenever the denitrification efficiency reaches a steady state. Accordingly, the inhibition of TMAH to the anammox bacteria can be significantly decreased, and both TMAH and the ammonium nitrogen can be treated simultaneously.

    Abstract: One or more dilution tubes for increasing the dilution of pulp as it enters a thickener are provided. One or more pipes, referred to here as dilution tubes, can be added to sides of a feed pipe of a thickener. One end of a dilution tube can open to a tank of the thickener, and the other end can open into the feed pipe. As pulp flows through the feed pipe, low pressure suction can be created that pulls water from the tank, through the dilution tube, and into the feed pipe. The water pulled in through the dilution tube can increase the dilution of the pulp. A highly diluted pulp can contact a flocculent efficiently and lead to a high settling rate in a thickener. Accordingly, the use of dilution tubes can increase the efficiency of a thickener.

    Abstract: A method for treating an organic waste, in which the organic waste is pressurized and continuously supplied to a high temperature and pressure treatment apparatus to produce a slurried material by blowing steam into the organic waste to cause a reaction while heating, pressurizing and agitating. The slurried material is dehydrated to produce a separated liquid product and a separated solid product. The separated solid product includes sufficient combustible content to produce a fuel product. The separated liquid product is purified.

  • Publication number: 20130227997
    Abstract: The invention relates to a method for separating the liquid part from the suspended matter in a sludge supplied in a continuous flow at a flow rate of QEB=V/hour. The flow is divided into at least two partial flows which are sprayed on top of one another into a sealed chamber of volume v<V/20, simultaneously injecting air therein at a flow rate d, said chamber being kept under overpressure conditions. The suspended matter of the thus treated flow is then left to decant in a collection container, with the cake or solid part falling to the bottom and separating from the liquid part which is continuously discharged.

  • Patent number: 8518272
    Abstract: A system for separating components of a composition according to density. The system includes a torque generating device, a separation device, and a housing. The separation device separates the composition into different components according to density. The housing accommodates the separation device. The housing includes a base having an interface that transfers torque from the torque generating device to the separation device, a cover, and a conduit for introducing the composition into the separation device without opening the cover.

  • Patent number: 8512576
    Abstract: A system for the production or handling of heavy oil comprises means (18) for introducing an immiscible viscosity-reducing fluid into the heavy oil at an upstream end of a flow line (10,22) to create a dispersion of oil and viscosity-reducing fluid, and means (24,30) for separating the viscosity-reducing fluid at least partially from the oil at a downstream end of the flow line. The separating means comprises a cyclonic fluid conditioning unit (24) connected receive the dispersion of oil and viscosity-reducing fluid from the downstream end of the flow line (22), said cyclonic fluid conditioning unit being constructed and arranged to subject the dispersion to a cyclonic conditioning process; and a gravity separator unit (30) connected to receive the conditioned dispersion from the cyclonic fluid conditioning unit.

  • Publication number: 20130186576
    Abstract: Evaporation technology is commonly used to to treat process waters that contain low solubility salts. The technology typically used is a brine boncentrator which uses seeded slurry techniques internal to the falling film evaporator which allows these scaling salts to co-precipitate with the seed crystals instead of scaling on the heat transfer surface. Such systems often employ hydroclones to recover and recycle seed crystals that would otherwise leave the process with the brine blowdown stream. These hydroclones (or other separation devices) often have regions of tight clearance that are susceptible to plugging which can lead to suboptimal process availability and greater maintenance obligations. The inventors have developed an apparatus called a “settling chamber” for separating large solid particles from the feed stream to the hydroclone to eliminate plugging, improve availability and reduce maintenance requirements.

  • Patent number: 8491854
    Abstract: A test tube insert includes a flange having a width greater than a width of a mouth of a larger test tube into which the insert is to be inserted. The flange defines a first central opening. An annulus extends integrally downward from the flange. The annulus includes a fenestrated wall and a floor defining a second central opening. A small test tube body, smaller than the larger test tube, extends integrally downward from the floor of the annulus with the second central opening forming a mouth of the small test tube body. The test tube insert is disposed in the mouth of the larger test tube. Fluid is transferred through the central opening and the fluid fills the small test tube body of the test tube insert and flows through the fenestrated wall once the small test tube body is full into the larger test tube.

  • Publication number: 20130161262
    Abstract: The current invention provides a novel process for the treatment and reclamation of drilling frac flowback and produced wastewater from the drilling industry. The wastewater is delivered to the EMC/F System from a frac tank or other reservoir. The wastewater is pumped into the system and is treated sequentially by passing through a mechanical hydrocavitation unit, an electromagnetic unit, an electrocoagulation unit and/or a hydrocyclone and a flocculation-sedimentation tank. Polishing of the final effluent is accomplished by passing the water through a mixed media tank.

  • Publication number: 20130140249
    Abstract: A method of delivering feed, for example a paraffinic solvent treated bitumen froth, to a separation vessel, for example a froth separation unit (FSU). The feed is delivered from one or more inlets into the side of a series of parallel plates that form a series of channels which may be either vertical or inclined at an intermediate angle. This feed inlet flow conditioning system is characterized by a Channel Reynolds number of less than 3000. Such inlet flow conditioning is particularly useful where the feed has particles with a bi-modal size distribution to be separated from an overflow stream. The low Reynolds number combined with the influence of the walls serves to mitigate the upward flux of the smaller particles, for example mineral solids, by trapping the smaller particles within a matrix of larger particles, for example precipitated asphaltene aggregates.

  • Patent number: 8449821
    Abstract: A system includes a controller and an apparatus that includes a housing having a volume and an inlet. The inlet can receive a fluid that includes a gas and a liquid. The apparatus also includes a baffle that partitions the volume into a first portion and a second portion. The baffle extends from a base of the housing. The first portion can receive the liquid and separate the liquid into a first part and a second part. The second portion can receive the second part of the liquid from the first portion. The controller regulates an amount of the second part of the liquid in the second portion such that a level of the second part of the liquid is higher than a height that the baffle extends from the base of the housing, thus enabling the use of the extra surge capacity in the vessel.
