  • Control Algae and Improve the Water Quality in Waste Stabilization Ponds

    Due to population growth, accelerated urbanisation and economic development, the quantity of waste water generated is increasing globally. Mainly in low-income areas, a large proportion of the waste water is discharged directly in the environment. When the waste water is treated, the treatment plants may not remove certain pollutants that can have a negative impact on the people and ecosystem. ...

  • Pollution prevention and control, West Wales

    Project Earlier this year, Remediation Strategies were asked to look into the development of a pneumatic barrier for a specific oil spill response scenario.  A pneumatic barrier uses compressed air in an underwater environment to create a vertical ‘bubble barrier’ and a standing wave at the water surface. The purpose of the barrier is to contain a given spillage of ...

  • Effects of open water on the performance of a constructed wetland for nonpoint source pollution control

    The seasonal performance of four differently configured constructed wetland systems was compared for the treatment efficiency of nonpoint source pollution. Dead plants in the constructed wetlands increased the nitrogen removal rate during winter by providing organic carbon, which is essential for the denitrification process. However, when the wetlands released phosphorus from the dead plants, the ...

  • Current status, problems and control strategies of water resources pollution in China

    The surface water of 10 major river systems across China has been under intermediate pollution with striking eutrophication problems in major lakes (reservoirs). More data from the Ministry of Environmental Protection of China showed that underground water in 57% of monitoring sites across Chinese cities was polluted or extremely polluted. Rural water pollution, the rising number of ...

  • Review and recommendations on a water pollution control framework for the pulp and paper sector in China

    The pulp and paper sector has been a significant source of water pollution in China for many years. The Chinese government has made great efforts on water pollution control for the pulp and paper sector. While actively participating in various international treaties and conventions related to environmental management and pollution control in this sector, China has created a comprehensive ...

  • Fate of hydrocarbon pollutants in source and non-source control sustainable drainage systems

    Sustainable drainage (SuDs) is an established method for managing runoff from developments, and source control is part of accepted design philosophy. However, there are limited studies into the contribution source control makes to pollutant removal, especially for roads. This study examines organic pollutants, total petroleum hydrocarbons (TPH) and polycyclic aromatic hydrocarbons (PAHs), in ...

  • Analytical Support for Cost-Effective Pollution Control

    ' Analytical tools have been developed by the World Bank Group to estimate rapidly the extent and impacts of pollution in a given situation and to support decisions on pollution management. These tools help decision makers to overcome the frequent lack of data on emissions from different sources, their impact on ambient quality, and mitigation alternatives.' Decision Support System for ...

    Based on 35 years’ experience working for the environment, French company Maguin has developed the Cercat filter for high temperature air pollution control. David Gambier describes the technology and its potential use in the glassmaking industry.Maguin has been present in the waste thermal treatment field since the 1970s, offering customers innovative and state-of-the-art concepts. The company’s ...

  • Air Pollution Control: Ready for the 21st Century

    The textile industry is plagued by air pollution problems which must be resolved. In particular, smoke and odor arising in the process require abatement. Air pollution control technology is available today which will serve the textile industry well into the 21st century. The nature of the problem The major air pollution problem in the textile industry occurs during the finishing stages, ...


  • Air Pollution Control in the Printing and Web Coating Industries

    For many U.S. companies in the printing and web coating business, the use of an Air Pollution Control System (APCS) to control harmful air pollutants is not new.  In these industries, depending upon their location, companies have been installing APCS since the early 1970's.  However, for some companies the clock is still ticking regarding their compliance with local, state and federal ...

  • Automatic control of pollutant on a shallow river using surface water systems: application to the Ebro River

    In this paper, the problem of automatic control of pollutant on a shallow river using surface water systems is addressed using a benchmark test case based in the Ebro River. The Ebro River presents flooding episodes in the city of Zaragoza in Spring when snow melts in the Pyrenees. To avoid flooding and high pollutant levels in living areas, some lands outside the city are prepared to be ...

  • A real-time, rapid emergency control model for sudden water pollution accidents in long-distance water transfer projects

    A real-time, rapid emergency control (EC) model is proposed to cope with sudden water pollution accidents in long-distance water transfer projects. The EC model outputs the method of EC based on pollutant properties. A generalized form of EC model is proposed and tested with a demonstrative project. The rapid prediction formulas of emergency control parameters (ECPs) are proposed under ...

  • Trans-jurisdictional pollution control options within an integrated water resources management framework in water-scarce north-eastern China

    The extent and severity of water pollution in China is well known, as is the fact that until the 11th Five Year Plan (FYP) in 2006, much greater importance was placed on economic growth than environmental protection. There were few incentives to reduce pollution owing to an inadequate legal framework, the absence of economic measures for pollution control in favour of a command-and-control ...
