  • Where Is the Most Water Reuse Taking Place?

    Water reuse is becoming increasingly important as water scarcity becomes prevalent throughout the world. Whether it’s referred to as water reuse, water recycling, water reclamation, or another name, the resulting purified wastewater can be used in many applications, both potable and nonpotable. In some places, water reuse has been slow to catch on, particularly because of the so-called ...

  • How to make domestic water reuse optimized through better strategies?

    Effective treatment of domestic waters and their reuse has become essential in modern times. Though such processes have technologically advanced in a significant fashion, it needs expertise or understanding of technology for proper execution. In addition, special strategies also have to be applied for process optimization. Strategies for greater conservation: It has become ...

  • U.S. utilities increasing water reuse investment

    Decreased technology costs are prompting more municipal water utilities in the United States to invest in new water reuse infrastructure. In fact, a new forecast projects more than $18 billion in water reuse and desalination projects are on tap in 17 states, according to Bluefield Research analysts. Although water scarcity is a conventional driver for this type of project, the analysts say the ...

  • Microbiological and physicochemical evaluation of the effluent quality in a membrane bioreactor system to meet the legislative limits for wastewater reuse

    The aim of this study was to assess the efficacy and effluent quality of a pilot-scale intermittently aerated and fed, externally submerged membrane bioreactor (MBRes) treating municipal wastewater. The effluent quality of the MBRes was evaluated regarding system ability to comply with the Greek legislative limits for restricted and unrestricted wastewater reuse. The average permeate flux was ...

  • Water treatment membrane coating promises chemical-free virus removal

    A novel material coating for water treatment membranes promises to improve the removal of water-borne viruses during treatment. This hydrogel coating, known as a zwitterionic polymer hydrogel, was created by scientists from Ben-Gurion University of the Negev and the University of Illinois at Urbana-Champaign. The virus-fighting membrane was created by grafting the new hydrogel coating onto ...

  • Estimation of water quality by UV/Vis spectrometry in the framework of treated wastewater reuse

    The aim of this study is to investigate the potential of ultraviolet/visible (UV/Vis) spectrometry as a complementary method for routine monitoring of reclaimed water production. Robustness of the models and compliance of their sensitivity with current quality limits are investigated. The following indicators are studied: total suspended solids (TSS), turbidity, chemical oxygen demand (COD) ...

  • Cost comparison of full-scale water reclamation technologies with an emphasis on membrane bioreactors

    The paper assesses the costs of full-scale membrane bioreactors (MBRs). Capital expenditures (CAPEX) and operating expenses (OPEX) of Spanish MBR facilities have been verified and compared to activated sludge plants (CAS) using water reclamation treatment (both conventional and advanced). Spanish MBR facilities require a production of 0.6 to 1.2 kWh per m3, while extended aeration (EA) and ...

  • Studies of selective adsorption, desorption and reuse of chemically altered biomass produced from aquatic macrophytes for treatment of metal-containing wastewater

    The aquatic macrophytes Salvinia sp. and Pistia stratiotes have a natural capacity to adsorb various elements, including heavy metals. This capacity was enhanced with a chemical treatment using NaOH alkaline solution for Salvinia sp. and a mixture of both Salvinia sp. and Pistia stratiotes at a proportion of 1:1, whose ...

  • Researchers investigate wastewater reuse in Namibian town

    A multi-year project in Namibia, headed by scientists from the Technische Universität Darmstadt, is looking for the best way to upgrade wastewater stabilization pond systems so the water can be reused to irrigate animal fodder crops. Despite its simple aim, the project has the lengthy name of “EPoNa-upgrading wastewater ponds to generate irrigation water, using the Cuvelai-Etosha ...

  • Pilot projects provide insights on potable water reuse

    Recycling wastewater is becoming more and more important, but it’s rarely consumed directly. What’s more common is direct potable reuse, a process in which wastewater is treated to drinkable standards. Instead of being injected into an aquifer or an environmental buffer, the treated water is commonly either distributed upstream of a drinking water treatment plant or added directly ...

  • A survey of attitudes and acceptance of wastewater reuse in Iran: Shiraz City as a case study

    People's attitudes are a key issue in the use of reclaimed wastewater. Unfortunately, there is not enough research on the use of reclaimed wastewater in developing countries such as Iran. The present study aimed to investigate public acceptance and citizens' attitudes toward reclaimed wastewater in Shiraz, Iran. A two-part questionnaire, designed to collect demographic data and information ...

  • Treatment of tannery wastewater for reuse by physico-chemical processes and a membrane bioreactor

    Treatment of wastewater from a tannery in Greater Ho Chi Minh City (Vietnam) was investigated on a pilot scale. After pre-treatment by the tannery that included batch-coagulation and sedimentation, the wastewater was treated by dissolved air flotation, a membrane bioreactor (MBR) and granular activated carbon (GAC) for polishing the MBR effluent. The average removal efficiency for organic ...

  • Solution blooming for fracking spills?

    Blooming salts may clean up after brine spills North Dakota's oil boom can have a salty side-effect. Wastewater from oil drilling and hydraulic fracturing – or fracking – is often laden with salts and can spill, contaminating soils. In 2014, for example, 42 such brine spills per week, on average, were recorded in North Dakota. Brine spills introduce so ...

  • Water reuse through managed aquifer recharge (MAR): assessment of regulations/guidelines and case studies

    Managed aquifer recharge (MAR) with reclaimed water is an important water reuse application. As an intentional way of recharging water into aquifers, MAR can be used to address water shortages and contribute to sustainable water resources management practices. The establishment of a MAR system depends on the source of recharge water, the selection of a recharge method and site, the type of ...

  • 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 ...
