    摘要: The invention relates to osmotically driven membrane processes and systems and methods for recovering draw solutes in the osmotically driven membrane processes. Osmotically driven membrane processes involve the extraction of a solvent from a first solution to concentrate solute by using a second concentrated solution to draw the solvent from the first solution across a semi-permeable membrane. Draw solute recovery may be carried out by various means including with the use of a membrane device. The draw solute recovery may also include the use of multi-stage solute recovery using distillation columns and/or membranes, where the recovery may be assisted by a heat pump.

    摘要: A method of assessing biofilm thickness in a membrane supported biofilm reactor (MSBR) of the type comprising a lumen containing a gas phase, a liquid phase, and a gas permeable membrane providing an interface between the gas and liquid phases, the method comprising the steps of charging the lumen with an inert gas, closing the lumen to establish an initial elevated pressure in the lumen, measuring the rate of change of pressure within the lumen, and correlating the rate of change of pressure (dP/dt) with biofilm thickness. The step of correlating dP/dt with biofilm thickness involves correlating dP/dt with the rate of diffusion of the inert gas (dn/dt), correlating dn/dt with an overall mass transfer coefficient (K), correlating K with the mass transfer coefficient of the biofilm (ICB), and correlating kβ with the biofilm thickness. Also described is a membrane supported biofilm reactor (MSBR) of the type comprising a gas permeable membrane providing an interface between a lumen containing a gas phase, and a liquid phase, characterised in that the MSBR comprises means for flushing the lumen with an inert gas, means for closing and re-opening the lumen, and means for detecting intra-membrane pressure within the lumen. The means for detecting intra-membrane pressure is provided by a pressure transducer.

    摘要: An apparatus for an ozone-based treatment of polluted water is disclosed. The apparatus generally comprises three stages. The first stage is an ozone treatment stage wherein the polluted water is treated with ozone gas. The second stage is a degassing stage wherein excess undissolved gases are removed from the water whereby the water exiting the degassing stage is essentially saturated with gases. The last stage of the apparatus is a membrane filtration stage wherein the gas-saturated water generally undergoes micro- filtration or ultra-filtration. Microbubbles formed during this final stage generally prevent the accumulation of particles and pollutants on the surface of the membranes and/or inside the openings or pores thereof; thereby acting as a self-cleaning mechanism for the membrane filter.

    摘要: A monitoring system and a method for monitoring a reverse osmosis (RO) membrane in an RO unit is capable of detecting the formation of mineral salt crystals on the surface of the RO membrane. The monitoring system includes a reverse osmosis monitoring cell coupled to the RO unit so as to receive a sample stream taken from either the feed stream to, or the concentrate stream from, the RO unit. The cell has a visually-observable RO membrane that is visible to an imaging system that creates and collects images of the visually-observable RO membrane, and that conveys an image data signal to a data processing system that is operable to translate the image data signal into visual images for display, and to correlate the data in the image data signal with a scaling condition on the RO membrane in the RO unit.
