  • Patent number: 10869943
    Abstract: An approach for treating a fluid transport conduit with ultraviolet radiation is disclosed. A light guiding unit, operatively coupled to a set of ultraviolet radiation sources, encloses the fluid transport conduit. The light guiding unit directs ultraviolet radiation emitted from the ultraviolet radiation sources to ultraviolet transparent sections on an outer surface of the fluid transport conduit. The emitted ultraviolet radiation passes through the ultraviolet transparent sections, penetrates the fluid transport conduit and irradiates the internal walls. A control unit adjusts a set of operating parameters of the ultraviolet radiation sources as a function of the removal of contaminants from the internal walls of the fluid transport conduit.

  • Patent number: 9718002
    Abstract: Used water-in-oil emulsified drilling muds are prepared for reuse by removing excess water. The excess water is removed by passing the used mud through a cavitation device, under controlled conditions, along with injected air. While the emulsion is heated in the cavitation device, the air is finely dispersed in it, so is able to absorb water evaporated from the discrete, discontinuous phase aqueous droplets in the emulsion. A mixture of incoming and aerated emulsion is maintained at an optimal temperature in a process tank while a steady state continuous process is controlled to utilize the heat input, after compensating for radiant heat losses and other system losses, substantially exclusively for the evaporation of water in the emulsion. The process is applicable to any water-in-oil emulsion.

  • Patent number: 9222464
    Abstract: If blades have been struck by wind that has reached a power reduction start wind speed that is lower than a conventional cut-out wind speed at which torque acting on a main shaft reaches the torque limit, a wind turbine generator performs torque reduction control for causing the change in the torque when wind speed is higher than the power reduction start wind speed to be different from change in the torque when wind speed is lower than the power reduction start wind speed so as to prevent the torque from exceeding the torque limit at the conventional cut-out wind speed. For example, if the wind striking the blades reaches the power reduction start wind speed, the wind turbine generator sets the slope of change in torque lower than that before the power reduction start wind speed is reached. Accordingly, the wind turbine generator can reduce the load acting on a device and suppress a reduction in power even if the blades are struck by strong wind.

  • Publication number: 20150129475
    Abstract: The present invention relates to a chemical feeder that includes a support plate that is positioned within the housing chamber of the chemical feeder, in which one or more extensions extend upward from an upper surface of the base plate of the support plate. The extensions can, with some embodiments, be in the form of peg extensions, arcuate extensions that can together define an impeller pattern, or a spiral extension. A distributor head having a plurality of distributor head apertures and at least one dome hole extends up through a support plate aperture in the base plate of the support plate, and distributes liquid horizontally and vertically relative to the base plate. The horizontally and vertically distributed liquid contacts a solid chemical material that is supported above the support plate, so as to form a treated liquid that includes dissolved chemical material.

  • Publication number: 20150122714
    Abstract: Systems and methods for performing hemodialysis to remove metabolic waste from the blood of a patient are disclosed. The systems and methods preferably comprise at least one blood processing apparatus that receives whole blood from a patient. Cellular blood components are removed from the whole blood by hemofiltration, to provide filtered plasma comprising metabolic waste that is substantially reduced of blood cells. The cellular blood components may be returned to the patient. The filtered plasma comprising waste may be removed from the blood processing apparatus through a waste path for further processing in a separate apparatus, or in the same apparatus in a second stage processing procedure to remove metabolic waste components and excess water from the plasma by hemodialysis. At least one of the hemofiltration and hemodialysis processing apparatus comprises a Taylor vortex-enhanced separation apparatus.

  • Publication number: 20150121867
    Abstract: A scale suppression apparatus capable of suppressing in a low-priced manner the generation of silica-based scale and calcium-based scale in the influent water containing at least a silica component and a calcium component, a geothermal power generation system using the same, and a scale suppression method are provided. The scale suppression apparatus includes a chelating agent and alkaline agent addition unit injecting liquid containing a chelating agent and an alkaline agent into a pipe arrangement through which influent water such as geothermal water or the like flows, and a controller controlling a pump and a valve of the chelating agent and alkaline agent addition unit. The controller controls the injection of the chelating agent and the alkaline agent and stops of the injection based on the signal output from a scale detection unit for detecting a precipitation state of the scale.

The mixed bacterial culture may be suspended within the slurry. The contaminated water may include contaminants associated with a non-metal, a metal, or a metalloid. The mixed bacterial culture may react with the contaminated water to reduce or remove the contaminants from the contaminated water to create a treated slurry. The reactor may output the treated slurry. The system may also include a filtration device to receive the treated slurry; remove, from the treated slurry, the mixed bacterial culture and the contaminants, reduced or removed from the contaminated water, to create treated water; and output the treated water.

  • Patent number: 8999173
    Abstract: An electrochlorination and electrochemical system for the on-site generation and treatment of municipal water supplies and other reservoirs of water, by using a custom mixed oxidant and mixed reductant generating system for the enhanced destruction of water borne contaminants by creating custom oxidation-reduction-reactant chemistries with real time monitoring. A range of chemical precursors are provided that when acted upon in an electrochemical cell either create an enhanced oxidation, or reduction environment for the destruction or control of contaminants. Chemical agents that can be used to control standard water quality parameters such as total hardness, total alkalinity, pH, total dissolved solids, and the like are introduced via the chemical precursor injection subsystem infrequently or in real time based on sensor inputs and controller set points.
