  • Biosolids ban struck down

    In 1994, Los Angeles County Sanitation Districts (LACSD) bought a 4,700-acre farm (called Green Acres Farm) in southwest Kern County for the purpose of land applying biosolids from its 11 wastewater treatment plants. LACSD land applied 800 wet tons/day at this site for several years. In 2006, Kern County voters passed Measure E on the ballot with 83 percent approval. This measure banned ...

  • MSW Management: Safely Countering the Rise of Landfill Odors

    One of the core challenges of landfill and compost site management is fighting the rise of foul odors. In addition, as communities expand further out from previous areas, they eventually become neighbors to landfills – calling for a comprehensive odor-control approach to countering odor complaints. In fact, compared to other industrial applications such as wastewater treatment and asphalt ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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, ...

  • 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, ...


  • 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 ...

  • 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. ...
