  • Membrane filtration and sonication for industrial wastewater reuse

    This paper presents an experimental study aimed at estimating the efficiency of the innovative process of ultrafiltration (UF) combined with sonication (Son.) for the refinement of treated effluent to be reused in wet textile processes. Such a novel approach, which has not yet been employed on a full industrial scale, has been experienced at pilot scale on the secondary effluent of the ...

  • Application of Membrane Technology for the Recovery and Reuse of Water

    ABSTRACT As water and sewer costs are expected to increase over the next decade, membrane technology will continue to be a viable and economical option in the recovery and reuse of water. This paper describes the mechanism of membrane effected separation (specifically reverse osmosis, ultrafiltration and microfiltration), membranes commercially available, membrane element configurations, and how ...

  • Membrane filtration of municipal wastewater effluents for implementing agricultural reuse in southern Italy

    Membrane filtration was investigated at field scale in order to assess its effectiveness for reusing municipal effluents in agriculture. The study was started on April 2002 and ended on September 2007, as part of a national R&D project (AQUATEC). Preliminary results, which we already reported elsewhere, concerned the first two project years while this paper refers to the subsequent period. Three ...

  • MBRs and Membranes for Industrial Water Reuse in California

    ABSTRACTOver the last few years, membranes have become the preferred treatment technology in municipal water and wastewater treatment. However, industrial treatment processes have continued to rely on conventional techniques. With recent improvements in membrane technologies, and with more stringent discharge requirements for industrial systems, membranes are ...

  • Water Reuse Terminology

    All water on Earth is used and reused, over and over, in an elegant water cycle. Water reuse occurs in various ways on a daily basis. It happens when a community’s treated wastewater is discharged into rivers or other water bodies. If you live in a community downstream of another, chances are you are reusing water from an upstream town. Scientifically proven advances in water technology ...

  • Membrane bioreactor technology for decentralised wastewater treatment and reuse

    There is a growing interest in utilising non-traditional water resources by means of water reclamation and water recycling for long term sustainability. Amongst the many treatment alternatives, membrane bioreactors (MBRs) have been seen as an effective technology capable of transforming various types of wastewater into high-quality effluent exceeding most discharge requirements and suitable for a ...

  • Characterization of modified PVDF membrane by gamma irradiation for non-potable water reuse

    Poly(vinylidene fluorine) (PVDF) membranes were grafted by gamma-ray irradiation and were sulfonated by sodium sulfite to modify the surface of the membranes. The characteristics of the modified PVDF membranes were evaluated by the data of Fourier transform infrared (FT-IR), X-ray photoelectron spectroscopy (XPS), field-emission scanning electron microscope (FE-SEM), the contact angle of the ...

  • Two Case Histories of Industrial Water Reuse Via Membrane Technology

    Abstract This paper describes two successful applications of ultrafiltration (UF) and reverse osmosis (RO) membrane technology used to reclaim water, reduce waste water discharge costs. The first case history covers oily waste water treatment at a major aluminum beverage can manufacturing plant. The second case describes treatment of waste water from a multi-plating bath section of a major ...


  • Water Reuse Options for Industrial Plants

    Water can be a high cost commodity for an industrial operation.  In addition, industrial water consumption uses approximately 22% of water worldwide, a percentage that bothers water-conscious customers. To cut back on costs, as well as reduce environmental impact, industrial plants are considering water reuse. Plants have several options when it comes to water reuse, which  ...

  • Self-Cleaning Pre-Filtration for RO Membrane Systems

    ABSTRACT A few years ago physical processes could only remove suspended solids from a water stream. Recent advances in technology now allow the removal of selected molecules and ions from a water stream by physical means using membranes. The membrane process has recently become very efficient and economically feasible for many industrial, commercial, municipal and even residential customers. ...

  • Advanced treatment of WWTP effluent with filtration leading to a pretreatment technique for membrane filtration

    In 2000 the European Union introduced the Water Framework Directive (WFD). The aim of the WFD is having an ecological and chemical balance for all surface waters in Europe in 2015. The European Commission identified 33 priority substances and their maximum allowable concentrations, FHI-values (Fraunhofer Institute), which are specified in the Annex of the WFD. The objective of this research is to ...

  • Intermittent operation of low pressure UF membranes for sewage reuse at household level

    A household-scale wastewater treatment system was operated with domestic sewage. The system could recover gardening/irrigation water from raw sewage or secondary effluent by low pressure ultrafiltration (UF). The UF membranes (surface area = 3.5 m2, pore size = 0.04 μm) were operated at constant transmembrane pressure (0.13 bar). The proposed technology was examined for ...

  • Reusing water for industrial processes and irrigation in Saudi Arabia

    Water is a scarce resource in Saudi Arabia and the public administration and private companies implement water reuse whenever possible. A reverse osmosis plant installed in the Eastern Province of Saudi Arabia helps to treat industrial waste water streams to quality levels that permit water reuse for industrial applications and irrigation. Kemira KemGuard antiscalant is used to prevent deposit ...

  • Utilizing unconventional water sources for industrial reuse

    Reclamation and reuse of unconventional wastewater sources for plant raw water, cooling water and process pre-treatment has increased substantially due to increases in the cost of drinking water, recurring water shortages that can impact business operations, and tightening government regulation. Water is required in almost every industrial sector for the processing and manufacture of products. ...

  • Screening optimisation for indirect potable reuse

    An automatic backflush pre-filter used for pre-treatment for secondary wastewater re-use was evaluated and optimised at two different mesh sizes over an 18 month period. The filter was initially run with a 500 μm rating mesh size, as recommended by the supplier of the downstream membrane filtration process, and then at 100 μm to investigate any change in water quality produced and associated ...
