  • 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 ...

  • The Benefits of an Integrated Air and Water Pollution Control Partner

    Although there has been substantial progress during the past several decades in reducing pollution, the EPA, other federal agencies and local governments continue to add and revise requirements and standards, making compliance a challenge for the industrial sector. These companies also face increasing public pressure not just to meet but to exceed pollution control standards, as studies continue ...

  • Reuse of Wastewater: Johnson & Johnson Medical

     Johnson & Johnson Medical's Sydney plant is recycling water previously discharged from its water purification system. The project demonstrates that common sense 'low-technology' options for recycling industrial process water can ease pressure on both water supply and sewerage systems, and save money at the same time. Background Johnson & Johnson Medical (J&J) ...


  • Sustainable Treatment and Reuse of Municipal Wastewater

    The uncontrolled disposal to the environment of municipal, industrial and agricultural liquid, solid and gaseous wastes constitutes one of the most serious threats to the sustainability of the human race by contaminating water sources, land and air, and by its potential contribution to global warming. With increasing population and economic growth, treatment and safe disposal of wastewater ...

  • Constructed wetlands for wastewater reuse in agriculture

    Deteriorating quality and increasing scarcity of water in Iraq demands a rethink in the way wastewater is managed. We show here that a constructed wetland can assist an existing sewage treatment plan not only to be lower than actual Iraqi effluent standards, but to also meet water quality criteria for reuse in agricultural production. Scarcity is one of several challenges to the Iraqi waters. The ...

  • Wastewater Wars: Reuse Projects in Texas

    As Texas continues to grapple with an impending deficit of water supplies to meet its future water demands, many water purveyors are looking to their existing resources to meet such needs. Although many water purveyors have already begun planning direct reuse projects, also known as “flange-to-flange” reuse, others have begun to realize the value of wastewater treatment plant discharges. ...

  • Current and Future Wastewater Reuse in Texas

    ABSTRACTThe reuse of treated wastewater effluent has served as a source of water supply in Texas for decades. While this has often occurred without detailed planning, the formal, planned reuse of treated wastewater effluent is increasing rapidly in the state, especially in the area around the Dallas-Fort Worth metroplex. To plan for the increased water demand, Texas has been divided into 16 ...

  • Potential for wastewater reclamation and reuse in Lebanon

    Eleven major wastewater treatment plants are planned for construction along the sea coast of Lebanon to handle the flow from the major urban centres. The plants are expected to generate approximately 640,000 m3 of treated sewage daily, and the effluent is planned to be disposed into the sea. In the light of the water deficiency that the country would be facing in the coming years, the reuse ...

  • Treatment matrix for reuse of upgraded wastewater

    ABSTRACTIn 2003 the Aquarec project sponsored by the European Commission under the 5th Framework Programme was started, aiming at “integrated concepts for reuse of upgraded wastewater with special focus on the European countries”. One of the key elements is the development of a treatment matrix, in which wastewater treatment processes are categorised as a function of the raw wastewater quality ...

  • Risk analysis of wastewater reuse in agriculture

    Two of the main concerns for wastewater reuse in agricultural irrigation are environmental and human security. Different research studies and practices have been developed recently in order to quantify the risk of possible environmental contamination of surface and groundwater resources as well as the risk to public health from enteric viruses. Other, far from negligible, related ...

  • Ozone as a Disinfecting Agent in The Reuse Of Wastewater

    More and more countries are taking measures to reuse wastewater. This has been prompted by the ever decreasing availability of good quality raw water and the increasing cost of producing potable water. Disinfection is a major treatment step in the direct reuse of reclaimed wastewater to ensure environmental and public health protection. “Disinfection is the destruction, inactivation or removal of ...

  • Water Reuse

    Water is an increasingly scarce resource for much of the World's population. Global warming, an increasing world population and generally increasing incomes mean the demand for water is likely to rise further. If current trends continue, we will use 40% more water by 2024 than we do now. In industrialised countries much of the water used for non-potable purposes such as industrial applications, ...

  • Championship Reuse

    ABSTRACTLas Colinas is a 12,000-acre high quality residential-commercial development in Irving, Texas, located between Fort Worth and Dallas. One of the foremost appeals of the development is the water features such as lakes and canals that are interspersed throughout the property. In order for the development to succeed and maintain its aesthetic appeal, it was necessary to secure dedicated ...

  • The innovative Osmotic Membrane Bioreactor (OMBR) for reuse of wastewater

    An innovative osmotic membrane bioreactor (OMBR) is currently under development for the reclamation of wastewater, which combines activated sludge treatment and forward osmosis (FO) membrane separation with a RO post-treatment. The research focus is FO membrane fouling and performance using different activated sludge investigated both at laboratory scale (membrane area of 112 cm2) and at on-site ...

  • Wastewater Reuse and Minimisation: Weatherall Smash Repairs

     Weatherall Smash Repairs took the initiative on cleaner production because the owner and staff wanted to help the environment. They’ve been rewarded with savings that will grow as water and disposal costs continue to increase, gains in productivity, and a future marketing advantage. They may also be able to sell the water recycling system they have developed, giving a further financial ...


  • Application performance of a new coagulant in wastewater reuse

    Ultraviolet (UV) absorption characteristics of poly-Al-Zn-Fe (PAZF), a polymerized coagulant containing three kinds of metallic elements prepared from a galvanized-aluminum slag, was analyzed by UV-visible spectrophotometry during its polymerization process. Pollutant removal by PAZF in treating various wastewaters was investigated, in comparison with that of polyaluminum chloride (PAC). The ...

  • Risk assessment of treated municipal wastewater reuse in Sicily

    In Italy, the restrictive approach for treated wastewater reuse in agriculture has led to some difficulties in promoting this practice. In order to assess the health risk associated with the use of wastewater in agriculture, an experiment was conducted in an open field near the constructed wetland (CW) system of San Michele di Ganzaria (Eastern Sicily), during the irrigation seasons ...

  • Evaluation of treatment schemes appropriate for wastewater reuse in Greece

    The scope of this paper is to propose wastewater reuse quality criteria and treatment specifications for Greece, taking into consideration reuse priorities and secondary effluent characteristics. The proposed wastewater reclamation criteria and tertiary treatment schemes were evaluated in terms of feasibility and effectiveness through lab-scale experiments. The experimental data were processed by ...
