  • 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 ...

  • Energy evaluation and treatment efficiency of vacuum membrane distillation for brackish water desalination

    Strict environmental regulations have led to the rapid development of membrane separation technologies for the production of potable water, for industrial water supply, and for the reuse and discharge of treated wastewater. Promotion of water recycling and the provision of potable water from brackish water prevent significant negative effects on the environment and drinking water supplies. This ...

  • 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 ...

  • Possibility of nuclear desalination through various membrane distillation configurations: a comparative study

    Three membrane distillation processes, direct contact membrane distillation, sweeping gas membrane distillation and vacuum membrane distillation, have been experimentally studied in a shell-and-tube capillary membrane module. Preliminary experiments were conducted using distilled water and sodium chloride aqueous solutions as feed. The effects of the operating parameters - flow rate, temperature ...

  • 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 ...

  • Distillation Process Can Yield Zero Liquid Discharge System

    Many industrial applications produce liquid waste as a by-product of their process. As environmental regulations governing the disposal of industrial wastewater become more stringent, it's imperative that innovative wastewater treatment solutions are used to treat this waste and minimize the environmental impact of disposal. While numerous technologies exist to treat industrial wastewater, Zero ...

  • Membranes and theoretical modelling of liquid–gas membrane separation for aromatic compounds removal from water: a review

    Liquid–gas membrane separation techniques - namely, vacuum membrane distillation, membrane air–stripping/sweeping and pervaporation - are non–equilibrium membrane separation processes emerging for the removal of aromatic compounds from industrial wastewater and polluted ground waters. This review focuses on polymeric hydrophobic membranes which are commonly employed in the liquid–gas membrane ...

  • Analysis of TNT and RDX in groundwater

    MATRIX: Water ANALYTE: TNT and RDX LIMIT OF DETECTION: TNT 1 ppb (mg/L), RDX: 5 ppb (mg/L) BACKGROUND: This application describes a field screening method for determining TNT and RDX concentrations in water. The method uses solid phase extraction to remove and preconcentrate the analytes from water. In the method, a 2 ...


  • Common Treatment Technologies for Nonhalogenated VOCs in Ground Water, Surface Water and Leachate

    It may be necessary to know other subsurface information to provide remediation of VOCs in the ground water. Treatability studies to characterize the biodegradability may be needed for any biodegradation technology. Treatability studies are usually necessary to ensure that the contaminated ground water can be treated effectively at the design flow. A subsurface geologic characterization would be ...
