摘要： Systems and methods for acoustically-enhanced membrane separation are described. The system may generally include a separation membrane and an acoustically-responsive structure positioned proximate the upstream side of the separation membrane. The system may further include a transducer for generating an acoustic field, wherein the acoustic field causes microstructures extending from the acoustically-responsive structure to oscillate and thereby create streaming effects in the region between the distal ends of the microstructures and the upstream side of the separation membrane. These streaming effects can prevent or remove separation membrane fouling, prevent the formation of cake layers on the separation membrane, and/or remove cake layer formed on a separation membrane.

摘要： The present disclosure is directed to various methods and systems for monitoring real time efficiency of filters as well as testing the filters with tests that are similar to real world use of the filters to update technical specifications of the filters. The methods and systems monitoring the real time efficiency of the filters may utilize one or more particle counters to monitor their efficiency in real time. The data collected by the particle counters may be utilized to determine whether respective ones of the filters need to be replaced or regenerated by a backwash regeneration process. The updated technical specifications from the real world testing of the filters may be utilized in determining whether respective ones of the filters need to be replaced or regenerated. These real world testing and real time monitoring reduces the likelihood that workpieces are exposed to contaminant particles reducing scrap costs.

摘要： Apparatus and method for semi-permeable membrane cleaning in particular, applying series of pulsed water stroke, made simultaneously with osmosis backward flow causing superposed membrane directional shaking and fouling detachment. Pulsed water stroke provided by water stroke generator as several momentum sharp changes in gauge pressure and induce velocity pulse of residual brine flow. The pulsed water strokes ideally induce resonance in the membrane. Osmosis backward wash may be provided either by injection for predetermined injection time, additional solution selected in such way that net driving pressure be-comes opposite to normal osmotic operation thereby providing a backward flow of permeate towards to the side opposite to normal operation mode, so as to lift said foulant, or by throttling permeate exiting from the permeate enclosure, until the net driving pressure value become equal to zero, during application of precise synchronized and opposing brine and permeate pressure strokes thereby providing a plurality of quick RO-FO-RO process changes. These procedures allow a membrane to be kept continuously clean and operate at higher recovery.

摘要： A system and process for removing divalent ions from a MEG feed stream is presented. The system includes a chemical treatment tank where chemicals are mixed with the feed stream to form insoluble carbonate and hydroxide salts. The system also includes a membrane-type solid-liquid separation unit that receives the feed stream from the chemical treatment tank and separates it into a filtrate containing MEG and a retentate containing the insoluble salts. The system may also include washing the retentate to remove additional MEG, which is then recycled to a MEG regeneration or reclamation process. The system may also include a dryer that receives waste slurry from the solid-liquid separation unit and dries it to form a solid waste, thereby facilitating its handling, storage, and disposal.

摘要： Described herein are apparatuses and methods for preventing or otherwise reducing scaling and fouling of a membrane using ultrasonic vibrations. One example method involves: (1) directing a solution to a membrane of a membrane assembly, where the membrane passes a solvent of the solution through the membrane at a first rate, and where the membrane prevents at least some of a solute of the solution from passing through the membrane; and (2) causing a piezoelectric material that is physically coupled to the membrane to produce ultrasonic waves directed at the membrane, where the ultrasonic waves induce oscillations in at least a portion of the membrane and thereby the solvent of the solution passes through the membrane at a second rate that is greater than the first rate.

摘要： A mass transfer process and device are provided that benefits enhanced mass transfer through a membrane as well as maintenance of membrane cleanliness via membrane surface vibration. Uniform amplitude and frequency vibration of the entire membrane in parallel to mass flux reduces internal and external concentration polarization, thereby improving mass flux, especially osmotic driven flux, through the membrane while affording minimal mechanical stress to the membrane. Vibration is provided by piezoelectric imbued membrane support medium wherein vibration is incited by oscillating electric fields generated by electrodes concomitant with the membrane support medium.

摘要： The present invention relates to membrane bioreactor (“MBR”) system that includes a mechanical membrane reciprocation system to reduce or eliminate membrane fouling. The disclosed MBR system can be operated with higher flux and lower fouling than MBR systems using air scouring. Furthermore the system can remove nitrogen and phosphorous with one RAS and one or no internal recirculation line. The membrane can be reciprocated by a low RPM motor connected to a pulley via belt to rotate rotor to convert rotational motion into reciprocating motion of membrane. Various mechanical means can also be employed to create the reciprocating motion.
