    Abstract: A polymer-free method and self-draining self-cleaning apparatus for treatment of water with high total dissolved solids including optional pretreatment, precipitation/flocculation, and separation. The pH is raised by addition of caustic soda and/or soda ash. In a vertical clarifier silo, the feed is gently mixed to cause dissolved solids to precipitate and agglomerate to form suspended flocculates. The clarifier includes an internal mixer surrounded by a cylindrical tube diffuser. Rotation of the mixer provides gentle dual circulation patterns within the clarifier that allow for flocculates of a predetermined size to settle from suspension. The clarifier may also include one or more vertical recirculation lines to recirculate some of the heavier flocculates at the bottom of the vessel into the mixer chamber to enhance precipitation via the seeding effect. The suspended flocculates are stripped from the feed water in a centrifugal separator. The clarifier silo may be trailer mounted for rapid deployment.

  • Patent number: 8105490
    Abstract: A water or wastewater treatment system to reduce phosphorus or other pollutant concentrations in water or wastewater may include an optional primary treatment stage in fluid communication with a biological secondary treatment stage. The secondary treatment stage may, in turn, be fluidly connected with a tertiary treatment stage, which may include a chemical treatment portion for reducing phosphorus or other pollutants to desired levels. The precipitated phosphorus and other solids or sludge produced from the chemical treatment portion may be recycled upstream for reuse in the primary, secondary, and/or tertiary treatment stages. Such recycle may reduce the amount of added chemicals required in the tertiary treatment stage to phosphorus or other pollutants to desired amounts.

  • Patent number: 8101077
    Abstract: A device for separating platelets from a fluid suspension comprises a mixing chamber operable to receive and mix fluid suspensions and an aggregating agent to form platelet aggregates and residual fluid components. A filter can be configured to be in fluid communication with the mixing chamber and can be further configured to collect platelet aggregates and allow residual fluid components to pass therethrough. The mixing chamber and the filter are operable by a user without input from an external energy source.

  • Patent number: 7985334
    Abstract: In one embodiment, the present invention relates to a method for thickening sludge carried along in waste water, wherein the waste water is subjected to a pretreatment reinforcing the flocculation and is subsequently introduced in the direction of gravity into a bath so as to separate the sludge from the water, in which the sludge particles descend under the action of gravity and are removed in the lower portion of the bath characterized in that the waste water, upon its introduction into the bath, is flowed against a baffle, by which the flow of the waste water in the bath is deflected.
