  • Water Use and Reuse in Manufacturing

    Efficiency advances in wastewater reuse and desalination are bringing on-site treatment within reach of more manufacturing operations Three factors — climate, overuse, and pollution — are now propelling the manufacturing industry toward a sea change in its water use. Demand for fresh water is high and increasing. The U.S. Census Bureau has estimated that the U.S.  ...

  • 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 ...

  • Mechanisms of scale deposition and scale removal in porous media

    Calcium sulfate scaling and scale removal have been studied experimentally and theoretically in a well-defined unconsolidated porous medium. The effects of injection rate, scale concentration and temperature on the rate of scale formation and the rate of its removal are investigated. The results of the experiments are used to develop mechanistic models for the prediction of the scaling process in ...

  • Large Scale Groundwater Modelling

    The hydrological model LISFLOOD is a spatially-distributed, partially physically-based rainfall-runoff model that has been devised to simulate the hydrological behaviour in large European catchments, with emphasis on predicting floods and droughts. In the model the groundwater component is represented by two interconnected linear reservoirs, with the outflow in some unit of time being ...

  • Small-Scale Biosolids Composting

    Cambridge, Ohio retrofitted a portion of its vacuum assisted drying beds into a covered composting facility, processing about 300 dry tons/year of biosolids and wood chips. Like many small communities in an agricultural area, the City of Cambridge, Ohio (pop. 14,000) managed biosolids generated by its 2.25 mgd Water Pollution Control Center (WPCC) via land application on farm fields. “Then ...

  • ADMS–Urban: developments in modelling dispersion from the city scale to the local scale

    Many countries perform national air quality assessments using grid–based numerical air dispersion models, generally referred to as 'regional' models. Advantages of these models include the ability to use temporally and spatially varying meteorology and model chemical reactions over large temporal and spatial scales. These models usually perform reasonably well against rural and urban background ...

  • Scale-up of the MIEX® DOC Process for Full Scale Water Treatment Plants

    The MIEX® DOC Process is a new process developed by Orica Watercare, South Australian Water Corporation and the CSIRO for the removal of dissolved organic carbon (DOC) from drinking water. Results from scale up of the process to a 170m3/day pilot plant have been reported previously (Nguyen, 1997). The process has now been successfully scaled up and trialed on a 1000m3/day pilot plant located at ...

  • Fragmentation in small-scale confined blasting

    Design of sub-level blasting rounds and optimisation has become more important now when the sizes of the blasting rings get larger. Sufficient fragmentation is one of the key factors, and in confined blasting as in sub-level caving, this influences the mobilisation of the blasted ring. Model scale tests have been made to understand the mechanisms of rock breakage and therefore fragmentation under ...

  • A comment on the independence of allocation, distribution and scale

    There has been considerable debate about the independence of the three policy goals of allocative efficiency, distributional equity, and ecological sustainability since Daly's (1992) paper on the subject (Prakash and Gupta, 1994; Daly, 1994; Stewen, 1998; Daly, 1999; Stewen, 1999). I would like to weigh in here, if I may, because I think it is a key policy issue requiring further discussion. ...

  • Scaling-up investments in natural infrastructure

    Wetlands occur wherever water meets land. These deltas, marshes, rivers, lakes and watersheds are the water systems that link the natural world and human societies, and make it possible to clean, store and provide water to grow food and run businesses. As we prepare to participate in ...

  • Controlling Scale Deposition and Industrial Fouling

    It costs US industry billions of dollars a year to control and remove the limescale that builds up in industrial equipment such a heat exchangers, evaporative coolers, boilers, chillers and other water fed equipment. Oil wells, for example, face significant scaling problems from the highly mineralized water that are extracted with the oil. Limescale not only increases downtime, maintenance ...

  • A solution for scale removal case study

    The Brookfields Restaurant chain consists of three large eateries located in and around Sacramento, Calif. Like many others, Brookfields Restaurants were equipped with water softeners to control lime scale on their hot water equipment, which consists of hot water heaters, dishwashers, steamers, coffeemakers and espresso machines. Even with the softeners, Brookfields Restaurants managers reported ...

  • Sustainability and the local scale: squaring the peg?

    This paper examines the causes of the failure by the Region of Waterloo (Ontario, Canada) to meet its objectives on sustainability. The analysis shows that in such macro matters as sustainability, scale does indeed matter, as do numerous other factors including the degree of trust in interrelations, perceptions and convictions, conflicting interests and competing agendas, the manner in which ...

  • Preventing scale in recreational vehicles and motorhomes

    Over 80% of North America is affected by hard water, which is a major problem for the owners of RVs and Motorhomes.  Consequently, whatever State you are visiting in your RV, or if you have a motorhome permanently located in a hard water area, limescale will clog pipes, ruin appliances, destroy faucets and cloud glassware. The award-winning, patented, Scalewatcher water-conditioner, from ...

  • Scalewatcher Removes Scale from Baptistery

    The Church of Christ in Shiner, Texas is no longer experiencing scale build up on its baptistery immersion tank following the installation of the computerized, electronic, water-conditioner Scalewatcher from Scalewatcher North America. The Scalewatcher system has also improved the clarity of the water, enhanced the operation of the heater and drastically reduced the amount of chlorine required. ...

  • Atomic-scale silicon device fabrication

    The driving force behind the microelectronics industry is the ability to pack ever more features onto a silicon chip, by continually miniaturising the individual components. However, after 2015 there is no known technological route to reduce device sizes below 10 nm. In this paper we demonstrate a complete fabrication strategy towards atomic-scale device fabrication in silicon using phosphorus as ...

  • Why Water Scale is Dangerous for Equipment

    Mineral scale occurs wherever circulating water exists, and it forms very fast (generally less than 3 weeks). Even a very thin layer, it will also cause insulation, make equipment inefficient, increase cost, and in some serious cases, it will shut down the whole system and even cause explosion. These problems have already existed in different fields, and are becoming worse and worse. ...
