  • Introduction of the IC reactor in the paper industry

    Among the anaerobic systems applied for the treatment of paper industry effluents, the IC (Internal Circulation) reactor is gaining a lot of interest. The reactor combines good biomass retention at the outlet with excellent mixing characteristics in the lower part of the reactor. This leads to smaller reactor volumes and less space requirements. Three examples of IC reactors at various recycle ...

  • Water governance and water users in a privatised water industry: participation in policy-making and in water services provision: a case study of England and Wales

    This paper examines how individuals can influence decisions about the delivery of water services in England and Wales. It first examines the capacity of individuals to shape government policy and then turns to an analysis of the private sector. In particular, we ask whether recent restructuring in the water sector – notably changes in business models and governance structures – has increased the ...

  • Decomposition analysis of water consumption-related chemical oxygen demand emission in Chinese industrial sectors

    Water shortage in China is caused by the uneven distribution of water resources, a situation that can worsen given overexploitation and pollution. Chemical oxygen demand (COD) emission is considered the most important water pollutant. Using the logarithmic mean Divisia index (LMDI) method, we analyse the main driving factors of the 2001–2011 changes in China's industrial water ...

  • Water, water everywhere: But is there enough to drink?

    Original story at MIT News At MIT, experts address the challenges of supplying clean, safe water to a growing world population. The challenge of supplying clean, safe drinking water to an expanding world population comes down to money, MIT economist Franklin Fisher ...

  • Life-cycle assessment of common water main materials in water distribution networks

    This paper examines the economy-wide environmental impacts linked to the manufacturing of PVC and ductile iron (DI) pipes, steel tanks, and to the generation of electricity for pumping in water distribution network optimization. The non-dominated sorting genetic algorithm (NSGA-II) is used to generate Pareto-optimal solutions of the benchmark ‘Anytown’ network expansion problem. Selected ...

  • Crumbling Concrete Water Networks Linked to Common Water Treatment Additive

    Concrete distribution and sewer networks are being corroded at an alarming rate partly because of a commonly used additive in the domestic drinking water and wastewater treatment process according to published reports in the journal Science. In countries throughout the world from industrialized nations like Australia and the USA to developing nations like Colombia, Ghana and the Philippines, the ...

  • The Need for a Total View of Water Networks

    The water industry is not short of software offerings, and so the arguments in favour of yet another software program had better be very good indeed. In this article we examine how one very significant community of users – operations managers, engineers and planners - have largely had their specific needs overlooked; we identify the type of system needed to fulfil their requirements and the ...

  • Water for Southern California: water resources development at the close of the century.

    INTRODUCTION In 1999, California observes the 150th year of the Gold Rush. Rather than an isolated historical event, it could be argued that the California Gold Rush never really ended, but rather that it was the first chapter in a mass migration unlike any other in history, both in scale and duration. At the founding of the Missions by Franciscan friars, Alta California was almost an ...

  • Bypass filtration in open circulating cooling water systems

    An open circulating cooling system is a method to remove process heat and is applied frequently for industrial purposes. In these systems heat is removed by evaporation of water to the surpassing air in the cooling tower. However there are some environmental disadvantages such as addition of chemicals to prevent the cooling water system from microbial growth and corrosion. The application of ...

  • Water business in China through the eyes of an entrepreneur

    ‘China has grown at an incredible pace for 30-odd years, but at the cost of the environment,’ comments Dutch entrepreneur Gijs de Bruin. The government is of course aware of this and the risk it poses to future economic growth, and it is the reason for the heavy on-going investment in environmental actions, including the water sector. ‘Water is one of the sectors in ...

  • The Potential of Solar-Powered Water Circulators to Help Solve Serious Water and Energy Problems in the U.S.

    With increasing human populations comes the corresponding increased need for improving water quality in lakes, wastewater ponds, potable water reservoirs, and other water storage facilities. Providing circulation within water reservoirs of all types has long been known to provide meaningful benefits, but the costs to achieve sufficient circulation through diffused aeration or mechanical mixers ...

  • Maximize Your Recycled Water Distribution through Technical Customer Service

    The Inland Empire Utilities Agency (IEUA), a municipal water district in southern California, provides high quality recycled water for landscape, agricultural, and industrial uses. Two industrial customers, an electrical power generating station and a textile dyeing company, required special efforts to address their recycled water quality needs. The electrical power generating station faced the ...

  • Intelligent pressure management reduces water losses and minimizes pipe brakes

    Leaks in water pipes and leaking valves in urban water distribution systems and pipeline networks, mainly in developing and threshold countries, are the reason for water losses of up to 50 percent in relation to the water quantity being produced in the water works. The articele of the 'Industrial Valves 2009' presents an effective pressure management on the basis of an intelligent control ...

  • Evaluation of xenobiotic impact on urban receiving waters by means of statistical methods

    Xenobiotics in urban receiving waters are an emerging problem. A sound knowledge of xenobiotic input, distribution and fate in the aquatic environment is a prerequisite for risk assessments. Methods to assess the impact of xenobiotics on urban receiving waters should address the diverse characteristics of the target compounds and the spatiotemporal variability of concentrations. Here, we present ...

  • A conceptual decomposition of MINLP models for the design of water-using systems

    The work presents a systematic methodology for the design of industrial water systems that combines principles of water-pinch (Wang and Smith, 1994a, 1994b) with mathematical programming techniques that enable the imposition of practical constraints and the generalisation of the conceptual tools into multi-contaminant problems. A superstructure model is formulated as an MINLP and solved via ...
