Abstract: A method for providing programmatic commercial insertion for a hybrid radio-TV channel of a system includes providing integrated or combined radio content from a radio system for broadcasting on the hybrid radio-TV channel, providing television content from a television system for display on the hybrid radio-TV channel during the content blocks; determining whether a video content is available from the radio system or from ad server during the ad insertion point; and determining whether a pre-loaded logo is available from the radio system during the ad insertion points. The method further includes inserting the video content from the radio system into the hybrid radio-TV channel for display if available, otherwise inserting the video content from the ad server, otherwise inserting the pre-loaded logo from the radio system, or otherwise displaying the video content from the television system and/or from the hybrid radio-TV channel. An associated system is also provided.

Abstract: A reverse osmosis system includes a plurality of feed pumps each having a feed pump input and a feed pump output, an input manifold in fluid communication with the feed pump inputs and a membrane feed manifold in fluid communication with the feed pump output. The system also includes a plurality of membrane chambers each in fluid communication with the membrane feed manifold and generating a permeate output and a brine output, each brine output in fluid communication with a brine manifold. The system further includes a plurality of booster devices each having a turbine portion with a turbine input in fluid communication with the brine manifold and a pump portion having a booster device pump input and a booster device pump output, each booster device pump output in fluid communication with the membrane feed manifold. The system includes a pump input manifold in fluid communication with the booster device pump input.

Abstract: A reverse osmosis system includes a first membrane chamber having a first feed line and generating a first permeate stream and a first brine stream. The reverse osmosis also includes a feed pump pressurizing the first feed line and a first booster device include communication with the first feed line. A flow balance line is also included in the reverse osmosis system, a second booster device, in fluid communication with the first permeate stream and the flow balance line. The reverse osmosis system also includes a second membrane chamber having a second feed line and fluid communication with the second booster device. The second membrane includes a second permeate stream in fluid communication with the flow balance line.

Abstract: A reverse osmosis system 110 includes a membrane chamber 112 having a feed line. The chamber 112 generates a permeate stream 114 and a brine stream 116 from the feed line 118. A feed pump 120 pressurizes the feed line 118. A first flow meter generates a first flow signal corresponding to a flow of fluid in the permeate stream 214. A booster device 172 has a turbine 176 in fluid communication with the brine stream 116 and a pump 174 in fluid communication with the feed line 118. A motor 178 is coupled to the turbine device 176 and a variable frequency drive 182 is attached to the turbine device 176 operating in response to the first flow signal. A second flow meter 218 generates a second flow signal corresponding to a flow of fluid in the brine stream 116 and a variable size nozzle 240 operates an opening in response to the second flow meter.

Abstract: A centrifugal pump includes a casing having an impeller chamber, an inlet, an outlet, and a bearing chamber. A shaft disposed within the casing has an impeller end and a motor end. The impeller is coupled to the impeller end of the shaft and is disposed within the impeller chamber. A bearing is disposed within the bearing portion. The bearing has an inboard end with an inboard-bearing surface and an outboard end with an outboard-bearing surface. The bearing and the shaft have a bearing clearance therebetween. A disc is coupled to the shaft on the impeller end which is spaced apart from the inboard-bearing surface. A seal ring is disposed between the disc and the inboard-bearing surface. The shaft, the seal ring, the disc, and the inboard-bearing surface define a thrust chamber therebetween. The thrust chamber is in fluid communication with the impeller chamber through the bearing clearance so that an axial thrust in an inboard direction is generated by the thrust chamber.

Abstract: The invention relates to a water desalination installation for the desalination of seawater according to the reverse osmosis method. This installation comprises at least one membrane module that is connected with a raw water feed line, via which raw water is supplied by means of a high-pressure pump; with a permeate line, via which the desalinated water is discharged; and with a concentrate line, via which concentrated salt water is discharged.

Abstract: The invention is directed to a rotor for a centrifugal pump. The rotor has a plurality of spaced apart, substantially circular, rotatable and substantially parallel disks. The disks contain a center aperture. A plurality of arcuate vanes are connected to the outer peripheral edge of the disks. The vanes extend from the outer peripheral edge of the disks in a direction away from the center aperture in the disks.
