  • Publication number: 20170088441
    Abstract: The present invention relates to a method and a device for deep oil removal from wastewater containing a low concentration of wasteoil. Wastewater containing a low concentration of wasteoil enters the device via an inlet and passes through a flow conditioner, causing the fluid to become uniformly distributed. Then, by means of a layer of oleophilic-hydrophobic fibers and hydrophilic-oleophobic fibers woven in a certain manner, a trace of oil droplets are captured and then coalesce and grow on the layer, and a trace of oil-in-water emulsion is demulsified and separated on the layer. Finally, by means of corrugation-enhanced sedimentation and separation, the oil droplets coalesce and grow and are then separated rapidly. The invention also provides a set of devices for implementing the method, having several parts such as a housing, a feed pipe, a flow conditioner, a fiber coalescence layer, a corrugation-enhanced separation layer, and a level gauge.

  • Patent number: 9571225
    Abstract: A method and apparatus for optimizing target error rates for link adaptation in a communication system. The method includes estimating a data rate associated with transmission of a data stream over a communication link. A required target error rate is then selected from a plurality of pre-defined target error rate values based on whether the estimated data rate is within a range of at least one of a plurality of pre-defined threshold values, where each of the pre-defined target error rate values maps to one of the plurality of pre-defined threshold values. A link adaptation parameter associated with the communication link is then selected or updated to maintain the required target error rate and the data stream is transmitted over the communication link using the selected/updated link adaptation parameter.
