  • 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 ...

  • Anaerobic Digestion Reduces Microplastics in Sludge

    Anaerobic digestion can help remove microplastics — a large cause of water pollution — during the sewage treatment process Microplastics, or tiny fragments of plastic, include microbeads, the plastic pellets present in thousands of household and personal care products, including toothpaste, cosmetics, and beauty scrubs. They also include fragments from the breakdown of anything in our ...

    If you’re a member of the NGWA Scientists and Engineers Section, you will soon receive your copy of the November-December 2017 of Groundwater®, an issue brimming with a wide range of topics. In his Guest Editorial, Randall J. Hunt offers five principles of uncertainty for groundwater modelers. He argues that uncertainty must ...

  • Research on the treatment of oily wastewater by coalescence technology

    Recently, oily wastewater treatment has become a hot research topic across the world. Among the common methods for oily wastewater treatment, coalescence is one of the most promising technologies because of its high efficiency, easy operation, smaller land coverage, and lower investment and operational costs. In this research, a new type of ceramic filter material was chosen to investigate the ...

  • 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 ...

  • What is Wastewater?

    What is wastewater? Wastewater, the waste discharge that first comes to mind in any discussion of stream pollution, is the discharge of domestic wastewater, which contains a large amount of organic waste. Industry also contribute substantial amounts of organic waste, some of which comes from vegetable and fruit packing; dairy processing; meat packing; tanning; processing of poultry, ...

  • Assessing Estrogenic Chemicals In Wastewater And Their Effects On Fish Reproduction – A Collaborative Effort Between Discharger And Researcher

    During the past 70 years, humans have benefited from the production of a large array of chemicals including pesticides, pharmaceuticals, personal care product ingredients, cosmetics and plastics. Over this time period it is estimated that more than 80,000 different chemicals have been released in to the environment, with many released through the discharge of treated domestic wastewater treatment ...

  • Research on Urban Water Environment Studies Using Reclaimed Wastewater –S. Â City in the Nostalgic Future that Recaptures its Waterfront Herritage

    Once S City was a prosperous rice farming region and had many irrigation ponds and channels until recently, but many irrigation ponds and channels had turned to residential areas. But S City has a historical site that is surrounded by three moats, built in the 5th century. An irrigation channel had provided water to the moats until recently, but the moats were frequently dried up by urbanization. ...

  • Ozone Based WasteWater Treatment

    The Australian Water Association held an international conference on 'Onsite and Decentralized' waste water treatment systems in Benalla, VIC. This was the abstract presented by Kyle Greene, Seair Canada Head of Research and Development. These portable wwtps are used in the extremes of northern Canada oil, gas and mining camps. Featuring: Heavy duty steel container, industrial weather coated, ...


  • The “Other Side” of Wastewater Treatment

    Peter Christou of Chimo Water & Wastewater Services Ltd. writes about his experience in the Antartica. I had no idea what to expect when I was asked to go to the McMurdo Research Station to help operate the wastewater and water treatment plants. All I knew about ...

  • Drinking rainwater and reusing wastewater

    Decentralized systems for drinking water processing could make a significant  contribution to the Millennium Development Goals. With the water concept in “self”, Eawag has demonstrated that membrane technology offers the chance to do just that. Lack of drinking water hygiene is one of the main sources of disease transmission worldwide, and in many situations centralized plants ...

  • Application of nanofiltration for reuse of wastewater

    The present research is a part of efforts to reuse wastewater by applying nanofiltration (NF) method for the secondary treatment of bio–treated wastewater and to check the quality of product water as irrigation water by using various analytical methods. For this, the performances of three different NF membranes (CK, GE–Osmonics; NF–270 and NF–90, Dow–FilmTech) were investigated using a cross–flow ...

  • What is biological wastewater treatment?

    Biological wastewater treatment harnesses the action of bacteria and other microorganisms to clean water Biological wastewater treatment is a process that seems simple on the surface since it uses natural processes to help with the decomposition of organic substances, but in fact, it’s a complex, not completely understood process at the intersection of biology and ...

  • Physical methods in wastewater treatment

    Physical methods of wastewater treatment are useful in water purification and recycling. We have proposed the role of nanoparticle in combination with ultrasound. Ultrasound (US), nanoparticle (NP) or in combination (US + NP) may offer an attractive proposition in the area of water purification. Ultrasound irradiation applications is that acoustic cavitation can affect a number of mechanical, ...

  • An overview of wastewater treatment in distillery industry

    Distilleries generate large volumes of high-strength wastewater that is of serious environmental concern. Spentwash disposal even after conventional treatment is hazardous and has high pollution potential due to the accumulation of recalcitrant compounds. Various physico-chemical and biological treatment options are available for the treatment of distillery wastewaters, but most of them could not ...
