  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • The benefits of planned maintenance for waste water odour control systems

    Abstract This paper summarises ERG’s experience in the first three years of their odour control maintenance framework agreement with Southern Water and ERG’s perceptions of the benefits Southern Water has derived from this agreement. Key Words Planned maintenance, odour control, chemical scrubbing, bio‐filters, carbon filters, waste ...

  • 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 ...

  • What classifies as water pollution and why is it an issue?

    The UN declared 2005-2015 as the International Decade for Action ‘Water for Life’. Yet each day thousands of people still die as a result of contaminated water. This does not even take into account the millions of organisms that perish every year thank to polluted water sources. Water pollution is a huge issue that is made more so by the fact that unfortunately, water is ...

  • 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 ...

  • Using constructed wetland systems to remove solids from highly polluted river water

    The Erh-Ren River is located in southern Taiwan and is one of the most polluted rivers in Taiwan. A pilot-scale constructed wetlands (ERRCW) system containing a free surface flow wetland (FSF) followed by a subsurface flow wetland (SSF) was set up to treat the polluted river water. The system was designed to include solids removal. A removal efficiency of suspended solids (SS) in the ERRCW system ...

  • Abatement vs. treatment for efficient diffuse source water pollution management in terrestrial-marine systems

    Marine ecosystems are affected by water pollution originating from coastal catchments. The delivery of water pollutants can be reduced through water pollution abatement as well as water pollution treatment. Hence, sustainable economic development of coastal regions requires balancing of the marginal costs from water pollution abatement and/or treatment and the associated marginal benefits from ...
