One example method includes dispersing a flocculant into thick fine tailings having a turbulent flow regime to produce turbulent flocculating tailings; subjecting the turbulent flocculating tailings to shear to build up flocs and increase yield stress, to produce a flocculated material having a non-turbulent flow regime; and shear conditioning the flocculated material to decrease the yield stress and produce conditioned flocculated tailings within a water release zone; and dewatering the conditioned flocculated tailings, for example by employing sub-aerial deposition. The thick fine tailings may have a Bingham Reynolds Number of at least 40,000 upon flocculant addition.

  • Patent number: 8883000
    Abstract: A water purification apparatus comprising at least: (a) one or more water purification components to provide a purified water stream, preferably having a conductivity of less than 1 ?S/cm; and (b) a stepper motor (35) to control the dispense of the purified water stream (28) from the water purification apparatus. Stepper motors can provide very fine and accurate control of the dispense of the purified water stream from the water purification apparatus, which control is unaffected by the flow or flow rate of the purified water stream.

  • Patent number: 8877061
    Abstract: An apparatus for purifying body fluid with solution including a casing having first and second input and output ports and dual safety or check valves monolithically formed with the casing that operate in conjunction with a dialysis machine or other apparatus used in hemodialysis is disclosed. The dual safety valves are configured at the input and output ports of a dialyzer such that the apparatus allows body fluid to move in one direction. This configuration prevents the reverse flow of body fluid back into the apparatus. A method for purifying body fluid with solution using an apparatus is further disclosed.

  • Patent number: 8871084
    Abstract: The invention relates to a fluid filter (1) comprising a collecting chamber (10) for a liquid which is separated from the fluid, in addition to a filter insert (4) which comprises a filter medium which is permeable to the fluid. The collecting chamber is arranged below the filter medium (5), and a liquid sensor (19) is arranged above the deepest point of the collecting chamber (10) and the liquid sensor (19) is protected from the liquid, at least sectionally, by means of a protective wall (18, 20). Said protective wall (18, 20) extends laterally and/or below the liquid sensor (19) and a liquid permeable connection is provided from the collecting chamber (10) to the fluid sensor (19).

  • Publication number: 20140311970
    Abstract: A rotating screen has one or more panels arranged into a cylinder, or drum. The panels have openings in a micro-screening range, for example 100 microns or less. Wastewater to be screened is fed to the interior of the drum. The drum rotates constantly but the rotation may be discontinuous and the speed of rotation may be variable. The drum may be cleaned by an air knife. If the wastewater contains oil and grease, a short hot water spray may be provided before cleaning with the air knife. Optionally, an internal auger conveys solids down the length of the drum to an outlet. The rotating screen may be used for primary treatment of wastewater. The rotating screen may be used produce screenings with a dried solids concentration of 5% or more, for example 6-7%. The primary sludge may be treated in an anaerobic digester.

  • Publication number: 20140299555
    Abstract: The invention relates to a method and system for recycling domestic greywater. Greywater is drawn from a greywater waste pipe through an overflow pipe of a sanitary fixture, thereby, permitting greywater to be collected for reuse without the need for complicated and expensive retrofitting and/or reconfiguration of existing plumbing infrastructure. The system and method of the present invention can easily operate independently or be integrated with domestic utility systems to supply these utility systems with greywater.

  • Patent number: 8852443
    Abstract: Various “no filter, no run” fuel filtration designs are described that include a variable restriction orifice (VRO) designed to vary the amount of fluid, for example fuel, that reaches a fluid outlet. The VRO has a fully open position at which a maximum non-zero fluid flow is permitted, and a fully closed position at which a limited amount of fluid can flow to the outlet. In the case of diesel fuel, the amount of fuel flow permitted at the fully closed position provides lubrication of downstream fuel system components, for example the fuel pump, but is insufficient to permit engine operation.
