Sustainable wastewater management for small communities in the Middle East and North Africa

Accelerated expansion of wastewater services to small communities in the Middle East and North Africa (MENA) is essential in order to address serious concerns over water scarcity and pollution in addition to meeting the demand for convenience and protecting public health. Centralized and conventional wastewater systems are currently the preferred choice of planners and decision-makers in MENA. Water and funding are not available to provide these centralized conventional services to small communities. This paper presents an integrated approach to sustainable wastewater management for small communities in MENA under the severe water resources crisis. The approach calls for a paradigm shift from centralized conventional wastewater systems to decentralized wastewater systems. Management of wastewater in MENA should start at home. Wastewater generation should be reduced through a combination of domestic water conservation measures. On-site systems must be improved and monitored to control pollution and to recover water for non-potable water uses. Should the circumstances not allow the use of on-site systems, wastewater should be transported and managed through a community system applying the principles of decentralized wastewater management and using the settled sewers for wastewater transportation where appropriate. This approach will facilitate the accelerated and sustainable extension of environmentally responsible wastewater services to MENA's small communities. It offers great potential for cost reduction, accommodates the necessary domestic water conservation efforts, reduces freshwater inputs in wastewater transportation thus eliminating unnecessary demand on freshwater, reduces associated environmental risks and increases wastewater reuse opportunities.

Fuzzy-based wastewater quality indices for pollution classification: a case study in the United Arab Emirates

This paper presents a fuzzy logic-based tool for assessing the pollution concentration of effluents generated by various industrial and commercial activities. The study proposes a fuzzy overall pollution compliance index (FOPCI) (range 0–100) to classify the wastewater discharged from various types of properties present in Ajman, United Arab Emirates. The work mainly focused on three types of pollution that can occur at the inlets of the wastewater treatment plant of Ajman, due to discharge of industrial and commercial effluents, namely pH pollution, salt pollution, and organic pollution. The proposed FOPCI integrates six characteristics, namely pH, Cl^?, SO₄ ^2?, conductivity, chemical oxygen demand (COD), and fats, oils, and greases (FOG) values into a readily understandable scale. The FOPCI is developed by using the Fuzzy Inference System Toolbox available in MATLAB in two steps, in which during the first step, three sub-indices, namely fuzzy pH compliance index, fuzzy salt compliance index, and fuzzy organic compliance index are developed. It is then processed in the second stage to develop the FOPCI. Fuzzy rules are used to classify effluents quality into six categories based on the concentration of pollutant in the effluent, namely “Excellent Quality”, “Good Quality”, “Acceptable Quality”, “Moderately Polluting”, “Highly Polluting”, and “Extremely Polluting”. This linguistic classification using fuzzy logic will be helpful as a decision support system to provide an outline for the prioritization of plans for wastewater management based on the values of the indices developed.

我国污染源监管业务流程研究

本文通过梳理我国污染源监管的历史沿革和日益严峻的环境污染问题,理清我国现阶段在污染源整个生命周期的不同阶段由不同环境部门主导的污染源监管模式和在此模式下形成的数出多源的数据库基本情况。从时间、空间、参与者三个角度分析该模式的缺点,针对环境统计、排污申报、排污收费等多个污染源数据库进行分析比较,列表找出各自数据的特点。通过分析指出我国污染源管理存在的不足,主要体现在污染源信息管理碎片化、多元化,数据互通性差,难以实现交换和共享,导致环境部门数据可靠性不高,信息公开不全面,社会公信力缺失。究其根本原因是我国目前缺乏一整套统一的、紧密衔接的污染源协同监管模式以及顺畅的污染源全过程管理数据流程。文章从实行排污许可证一证式管理制度、污染源企业报告制度、信息公开制度、加强违法处罚力度和完善企业环境信用等方面提出政策建议。     

Industrial Development Versus Environmental Conservation at Local Scale: A Case Study from Southeastern Spain

Local scale has an important role in environmental management. In Spain, rapid industrialization has occurred in the last three decades, leading to substantial changes in socioeconomic relations and resulting in significant environmental degradation. This paper describes the environmental status of the township of Sax (Alicante, in southeast Spain), which has passed from agriculture to industrial manufacturing in 50 years. The human population has grown exponentially during the second half of the 20th century, with a 91% increase from 1955 to 1995, coinciding with strong growth in manufacturing (factories increased fivefold in the period 1955–1976) and important changes in the working population and land use. Illegal rubbish dumps, water pollution, forest fires, erosion, and degradation of wildlife habitats are the main outcomes of these dramatic socioeconomic and demographic changes. The administration has focused on the control of water pollution and waste management, while nongovernmental organizations have concentrated on the prevention of forest fires and the development of environmental education programs. These measures are insufficient to manage current environmental degradation, and an environmental management plan for the study area is discussed. Increasing effort in waste management and industrial wastewater control, changes in land-use policy, and the creation of an advisory committee to increase public participation in decision-making have been identified as environmental target objectives for the coming years.

Assessment OF SURFACE WATER QUALITY at Large Watershed Scale: Land‐Use,Anthropogenic, and Administrative Impacts

Understanding the impacts that influence water quality is critical to the development of best management practices at the large watershed scale. This study describes the spatiotemporal variation in surface water quality and identifies their main impact in the Haihe River basin, China. Multivariate statistical techniques are applied to analyze the similarities among the sampling sites and to identify the main pollution sources in surface water. Results show that: (1) the basin can be clustered into two regions, water quality being better in the mountainous vs. plain regions; (2) water quality improves due to implementation of a strict state policy on environmental pollution control, prodded by the hosting of the Olympic games in the cities of Beijing and Tianjin; and (3) agricultural and residential land uses as well as livestock‐breeding are the main sources affecting water quality in the mountainous regions, whereas rural waste discharge — including domestic waste sewage, human and animal feces, and solid waste — significantly influences water quality in the plain regions. The waste discharge of industrial factories may be a significant source of water pollution in the plain regions. Results indicate that the environmental management from pollution sinks and sources, long‐lasting legal framework, and adequate economic incentives should be improved to optimize the large‐scale watershed management under the background of the rapid development of countries like China.     

Implementing industrial ecology and design for environment practices: Lawrence livermore national laboratory

Lawrence Livermore National Laboratory (LLNL), one of the nation's three national security laboratories, is initiating a major research effort in industrial ecology with the goal of increasing the economic and environmental efficiency of the U.S. and global economies. Closer to home, ongoing efforts to reduce LLNL's environmental impact on the surrounding community provide an example of how the environmental efficiency of a major research facility can be systematically improved. In the late 1980s, LLNL initiated its waste minimization and pollution prevention program, changing its focus from end-of-pipe waste management to a proactive and preventive strategy—total quality environmental management (TQEM). LLNL's success in integrating pollution prevention with R&D and operational activities is well illustrated by the waste reduction and energy and water conservation accomplishments described in this article. LLNL represents a model of how industrial ecology, design for environment, and pollution prevention can be incorporated into a comprehensive R&D and operational program. This article describes LLNL's developing industrial ecology program, gives some specific technical accomplishments that have application to many industrial facilities, and presents a case study of TQEM at LLNL's remote experimental test facility, Site 300. The integration of TQEM philosophy with LLNL's scientific capabilities holds much promise for new ideas and creative solutions to national and international industrial ecology concerns.

An improved understanding of the environmental impact of open drains in a Nigerian city

Summary An investigation has been made of the environmental impact and degree of pollution resulting from open drains in Ibadan city, Nigeria. The parameters measured included: (a) pH, biochemical oxygen demand (BOD), dissolved oxygen, alkalinity, hardness, and calcium, magnesium and chloride content of the water, and (b) depth, width, velocity, discharge and waste water generation; in drains located in three areas categorised according to population density. The results illustrate important differences in the wastewater properties of drains in low-medium and high population density (traditional core) areas of the city. While previous attention has been largely focused on the degree of pollution from open drains as characterised by parameters listed under (a), and on environmental hazards such as erosion, flooding and public nuisance, this study went further. It uses the parameters listed under (b) to recommend appropriate technology designs and some management techniques to arrest the problem.Dr A.Y. Sangodoyin is a member of staff of the Department of Agricultural Engineering at the University of Ibadan. He is qualified as a civil engineer.
