  • Brackish water treatment for reuse using vacuum membrane distillation process

    The availability of fresh water is vital for all human activities and in particular for improving living conditions, health and overall well-being. Pressure on scarce fresh water resources can be reduced by treating and reusing brackish water by advanced membrane treatment technologies. In this study, brackish water originating from effluent discharge of a local coal mine, seawater, groundwater ...

  • Recycling of coal seam gas-associated water using vacuum membrane distillation

    Coal seam gas-associated water (CSGAW), which is a by-product of coal seam gas (CSG) production typically contains significant amounts of salts and has potential environmental issues. In this study, we optimized a bench-scale vacuum membrane distillation (VMD) process with flat-sheet hydrophobic polytetrafluoroethylene (PTFE) membranes for the treatment of synthetic CSGAW (conductivity = 15 ...

  • Osmotic distillation using Liqui-Cel® membrane contactors

    Osmotic distillation — a separation process in which a liquid mixture containing a volatile component is contacted with a microporous, non-liquid-wettable membrane whose opposite surface is exposed to a second liquid phase capable of absorbing that component — is nearing commercialization for the concentration of beverages and other liquid foodstuffs, and is ...

  • Water reclamation from shale gas drilling flow-back fluid using a novel forward osmosis–vacuum membrane distillation hybrid system

    This study examined the performance of a novel hybrid system of forward osmosis (FO) combined with vacuum membrane distillation (VMD) for reclaiming water from shale gas drilling flow-back fluid (SGDF). In the hybrid FO-VMD system, water permeated through the FO membrane into a draw solution reservoir, and the VMD process was used for draw solute recovery and clean water production. Using a SGDF ...

  • Vacuum systems for tall-oil applications

    Tall oil is a viscous oily liquid and considered one of the most important by-products of wood pulp manufacturing. Through a fractioning process crude tall oil can be turned into valuable fatty and resin acids. Vacuums play a key role in this procedure. An application in Finland currently proves that technology from Hanover-based Körting is ideally suited for this purpose. ...

  • Vacuum evaporation treatment of digestate: full exploitation of cogeneration heat to process the whole digestate production

    Vacuum evaporation represents an interesting and innovative solution for managing animal waste surpluses in areas with high livestock density. To reduce operational costs, a key factor is the availability of an inexpensive source of heat, such as that coming from an anaerobic digestion (AD) plant. The aim of this study was to test vacuum evaporation for the treatment of cattle slurry digestate ...

  • Food Processing: Odor Control in Edible Oil Processing

    Abstract: The problems with odor around a typical edible oil deodorizer are discussed in detail, and a three-step solution to eliminate these problems is presented. The three steps are a distillate recovery system which recovers most of the fatty acid in the deodorizer vapor discharge as a valuable byproduct, a closed loop barometric cooling water system which keeps the fatladen ...

    This report describes how treatment of landfill leachate by means of forced circulation vacuum evaporation provided: an environmental benefit from use of biogas as power supply a big saving in disposal cost due to waste volume reduction a return on investment of less than two years Introduction Solid Waste Management in Greece has been remarkably upgraded during the last ...

  • Utilizing available `coldness` from Liquefied Natural Gas (LNG) regasification process for seawater desalination

    Abstract With the increasing use of natural gas, Liquefied Natural Gas (LNG) is becoming more extensively used to ease the storage and transport of gas. The process of returning the natural gas to its gaseous state (regasification) prior to distribution to the gas pipeline absorbs large quantities of heat and therefore provides a readily available and inexpensive source of "coldness" at low ...

  • Olive mill waste water treatment

    The production of olive oil generates two kind of waste waters: RINSING WATERS: the quantity is subject to change. It can be re-circulated, after the settling to remove the solids, or discharged directly. SLUDGE: vegetation water with additional water, whose quantity is subject to change. In case of traditional oil mills, the hot additional water flows to the inlet of the centrifuge. Part ...
