The present application is directed to the separation of a solid fraction from a fluid sample particularly a therapeutic cellular fraction from a biological sample such as a bone marrow sample by a porous filter which separates a filtration unit into an upper pre-filtration chamber into which a fluid sample requiring cell separation is introduced and a lower post-filtration chamber into which a fluid capable of transmitting an acoustic standing wave is introduced. An acoustic element is coupled to a substrate which is located within and at the bottom of the lower chamber and which resonates in response to the acoustic generating element and generates a standing wave through the two fluid phases and the filter to agitate the sample. Simultaneously, a cyclic process of vacuum draw, causes movement of the sample downwards through the filter. Vacuum pressure, fluid flow rate and frequency of vibration are controlled from a remote unit housing appropriate pumps and valves.

Embodiments of the invention provide methods of removing ions from a feed water stream using a flow-through capacitor and a controller for performing the methods. A target value for a water property concentration or a fixed percent removal of a water property concentration to be removed is established for a treated water stream exiting the flow-through capacitor. A feed value for the water property concentration is measured in a feed water stream entering the flow-through capacitor. An amperage of the flow-through capacitor and a flow rate through the flow-through capacitor is controlled to remove ions from the feed water stream to achieve the desired removal of the water property.

Embodiments of the invention provide a method of regenerating a capacity of a flow-through capacitor. A target value for a water property concentration in a discharge water stream exiting the flow-through capacitor is established. A feed value for the water property concentration in a feed water stream entering the flow-through capacitor is measured. An amount of the water property concentration to be added to the feed water stream is calculated based on the feed value to achieve the target value for the water property concentration in the discharge water stream. An amperage of the flow-through capacitor and a flow rate through the flow-through capacitor is controlled to add ions to the feed water stream to achieve the target value for the water property concentration in the discharge water stream. In some embodiments, the amperage can be set and the flow rate controlled to achieve the target concentration.

In a method for water treatment by chlorine disinfection, a chlorine stabilizer is dosed into water to be treated as far as a predetermined chlorine stabilizer concentration in said water is achieved. As soon as the predetermined chlorine stabilizer concentration is achieved said achieved chlorine stabilizer concentration is maintained in said water constant. A chlorine disinfectant concentration is adjusted in said water to be treated to a predetermined chlorine disinfectant concentration in said water by dosing a non-stabilized chlorine disinfectant (free chlorine) into said water to be treated. Therefore advantages of free chlorine and stabilized chlorine disinfection and facilitating to reduce DBPs at low chlorine stabilizer concentrations in water can be combined, without compromising disinfection safety.

The oil-water separator is installed in a substantially horizontal crude oil pipeline for separating water from the oil and water mix. The separator includes a vortex and settling chamber extending downward from the pipeline. The segment of the pipeline having the separator defines a generally T-shaped configuration. Oil and water phases flowing through the pipeline drop into the chamber as it flows through the pipeline and over the chamber. The denser water tends to settle into the bottom of the chamber, while the lighter oil is entrained back into the flow through the pipeline. A sensor detects water collected in the bottom of the chamber and provides a signal to open a drain valve when sufficient water has been collected. While only a single separator serves to collect a substantial fraction of water, a series of separators may be installed along the pipe to remove more water from the oil.

Принадлежит: Individual

The present invention relates to the chemical engineering for getting useful products from aqueous solution of electrolytes with various concentration by electrolytic method and it can be used for the production of disinfectants widely utilized in medicine, biology, and ecology. This invention solves a task of disinfectant production with the capacity of a single electrolyser amounting to 1200 litres per hour and up to 600 grams of active chlorine per hour by utilizing 3-7 gram sodium chloride (NaCl) for the production of 1 gram of active chlorine on the basis of a reliable and safe hydraulic structure. The main condition for the effective solving of the task is the initial directing of fresh water supply into the internal tubular cathode chamber for the cathode cooling purposes, before the participation in final disinfectant production process. A coolable cathode enables to increase the hold-up time of the electrolyte in the electrode chamber without application of circulation circuits improving significantly the efficiency of sodium chloride utilization. The simplicity of the method makes it possible to increase both the productivity of a single electrolyser and the efficiency of the process.

Wastewater treatment

Номер: US20140021131A1

Автор: Alexander Fassbender

Принадлежит: Individual

A wastewater treatment system includes wastewater having nitrogen-containing compounds, an anoxic zone having denitrifying bacteria, and an aerobic zone having nitrifying bacteria. The anoxic zone is coupled to the aerobic zone, and wastewater flows from the anoxic to the aerobic zone or vice versa. A fluidized bed heat exchanger configured to accept heat from a heat engine and to transfer the heat from the heat engine to the wastewater is positioned in the aerobic zone or the anoxic zone. The fluidized bed heat exchanger includes particulate media, and fluidization of the particulate media scrubs bacterial growth from portions of the fluidized bed heat exchanger. Treating wastewater can include flowing wastewater having nitrogen-containing compounds into a biological reactor having an anoxic zone and an aerobic zone, and heating the wastewater with heat from a heat engine to facilitate denitrification reactions in the anoxic zone and nitrification reactions in the aerobic zone.

Автор: Bernard F. Duesel, Jr., Craig Clerkin, Michael J. Rutsch

Принадлежит: HEARTLAND TECHNOLOGY PARTNERS LLC

A compact and portable liquid concentrator includes a gas inlet, a gas exit and a flow corridor connecting the gas inlet and the gas exit, wherein the flow corridor includes a narrowed portion that accelerates the gas through the flow corridor. A liquid inlet injects liquid into the gas stream at a point prior to the narrowed portion so that the gas-liquid mixture is thoroughly mixed within the flow corridor, causing a portion of the liquid to be evaporated. A demister or fluid scrubber downstream of the narrowed portion removes entrained liquid droplets from the gas stream and re-circulates the removed liquid to the liquid inlet through a re-circulating circuit. Fresh liquid to be concentrated is also introduced into the re-circulating circuit at a rate sufficient to offset the amount of liquid evaporated in the flow corridor.

A solar-operated submersible pump pumps waste water from just under the surface of a waste water pit, through a pair of automatic backflushing filters and out misters located around the bank of the waste water pit. At a predetermined pressure across the automatic backflushing filters, the automatic backflushing filters are reverse cycled, one at a time, to backflushing particles back into the waste water pit. Periodically, the misters are purged and/or cleaned to remove particles therefrom. In response to sunlight, solar panels provide DC voltage directly to the submersible pump. If pressure from the submersible pump gets excessive, a pressure relief valve removes the excess pressure.
