  • Chemistries of Ozone for Municipal Pool and Spa Water Treatment

    Ozone generated by ultraviolet (UV) radiation is used in North America for treating (mostly residential) spa and pool waters almost exclusively, while only a handful of North American municipal pools and spas are using ozone generated by corona discharge technology in accordance with well–established German teachings. On the other hand, several thousand European municipal swimming pools and ...

  • Profile of Ozone/Bromine Sanitation Systems for City of Tucson Municipal Pools

    Due to the inherent risks associated with the use of chlorine gas as a sanitizer for the City of Tucson’s twenty-six municipal swimming pool sites, I found myself in search of an alternative water sanitation method. The challenge was clear; find a system that would be safer to manage than gas chlorine, yet yield the same favorable sanitation and water quality results. Since all the sites ...

  • Ozone is Not Just for Residential Potable Water Treatment

    It has been over 170 years since the d iscovery of the ozone (O3) molecule. Since that time, scientists and engineers have been testing and evaluating ways to use ozone in many different processes, from water and air treatment to surface and food sanitation. The evolution was somewhat slow in the early days, taking nearly 50 years before Europeans found, in 1886, that ozone could be used for ...

  • Novel anaerobic digestion process with sludge ozonation for economically feasible power production from biogas

    A novel process scheme was developed to achieve economically feasible energy recovery from anaerobic digestion. The new process scheme employs a hybrid configuration of mesophilic and thermophilic anaerobic digestion with sludge ozonation: the ozonated sludge is first degraded in a thermophilic digester and then further degraded in a mesophilic digester. In small-scale pilot experiments of the ...

  • Environmental Assessment of Municipal Waste Management Scenarios: Part II Detailed Life Cycle Assessments

    The European Commission’s Strategy on the Prevention and Recycling of Waste outlines why life cycle thinking is essential in the move towards more sustainable consumption and production. The importance of life cycle thinking is further highlighted in the Commission’s complimentary Strategy on the Sustainable Use of Natural Resources, in its Integrated Product Policy, as well as in the proposed ...


  • Environmental Assessment of Municipal Waste Management Scenarios: Part I Data Collection and Preliminary Environmental Assessments for Life Cycle Thinking Pilot Studies

     Landfilling can be almost eliminated and reductions in climate change contributions of 7% can be achieved relative to monitoring data for Kyoto targets in regions with high percentages of biodegradable waste using advanced waste management systems. Additional benefits outside the region are achieved through energy recovery, recycling, and compost production. These are quantified using life cycle ...


  • In Search of Ideal Groundwater Treatment

    As surface water supplies become increasingly polluted and difficult to treat, the use of groundwater continues to increase. Every day, more than 77 billion gal of water are withdrawn from aquifers for a variety of uses including human consumption. Worldwide, groundwater makes up 95% of available freshwater, and nearly half of the U.S. population receives all or part of its drinking water from ...

  • The effect of microbubbles on gas-liquid mass transfer coefficient and degradation rate of COD in wastewater treatment

    A commonly used aeration device at present has the disadvantages of low mass transfer rate because the generated bubbles are several millimeters in diameter which are much bigger than microbubbles. Therefore, the effect of a microbubble on gas-liquid mass transfer and wastewater treatment process was investigated. To evaluate the effect of each bubble type, the volumetric mass transfer ...

  • Water reuse technology trains for medium-level water

    Wastewater is considered as stable and substantial amount of alternative water resource. In case of South Korea, it is known that 73.2 percents of supplied water discharge 16 million m3/day of treated effluent from municipal wastewater treatment plants. Calculation simply tells that 0.58 billion m3/year can be available if only 10 percent of wastewater could be reused. In this study, a pilot MBR ...

  • Review on hospital wastes Al Baha University KSA

    Medical waste management is of a great importance due to its potential impact to environment and consequently to human health. In the recent years, many efforts have been made by environmental regulatory agencies and waste generators to better managing the wastes from healthcare facilities. In the past, medical waste was often mixed with municipal solid waste and disposed in residential waste ...

  • Common Treatment Technologies for Halogenated SVOCs in Ground Water, Surface Water, and Leachate

    It may be necessary to know other subsurface information to remediate halogenated semivolatile organics in water. Treatability studies may be required to determine the contaminant biodegradability for any biodegradation technologies. Treatability studies are also necessary to ensure that the contaminated ground water can be treated effectively at the design flow. A subsurface geologic ...

  • New EEA Report

    Environmental Signals 2000 is the first of a series of regular indicator reports on the European environment to come from the Agency. Published annually, these reports will provide policy makers, experts and the general public with the very latest assessments of the EU’s environment. The reports will fill the five-year gaps between the EEA’s main state of the environment reports such as ...

  • EPA plans to make greenhouse gas (GHG) emissions reporting mandatory

    Mandatory carbon (CO2) emissions reporting is more important than ever as the United States works with facilities to reduce substances known to adversely affect air quality, the climate, and lead to global warming. Most of the known matter that is destroying the earth’s ozone layer and contributing to global warming is derived from manmade compounds and chemicals with high global warming ...

  • Summary and Conclusions of the Study

    Background and objectives According to 'Affald 21', the Danish national waste plan for the period of 1998-2004 (Ministry of Environment and Energy, 1999) recycling of household waste should be increased over the coming years. The plan is focused on increasing sorting and collection from the households, in which glass is one of the fractions.The first objective of this project is to examine ...

  • Chloramines

    OVERVIEW When chlorine is added to a water supply containing certain organics, the formation of halogenated organics occurs. Called 'trihalogenated methanes' (THM's) these reaction products are suspected carcinogens and maximum allowable limits in municipal supplies are imposed by the U.S. Environmental Protection Agency (EPA). To reduce the potential for the formation of THM's, many U.S. ...

  • Reporting of greenhouse gases (GHGs) to be mandated for top 13,000 facilities

    The newly formed Obama administration has listed greenhouse gas (GHG) tracking and reporting as a major goal, with the objective of protecting the future of the environment by reducing today's carbon footprint. If no action were taken, the makeup of the earth would significantly altered. Future actions will establish a market drive carbon cap and trade program to drive GHG emissions ...
