European Council
The European Council (informally EUCO) is a collegiate body that defines the overall political direction and priorities of the European Union. It is composed of the heads of state or government of the EU member states, the President of the European Council, and the President of the European Commission. The High Representative of the Union for Foreign Affairs and Security Policy also takes part in its meetings. Established as an informal summit in 1975, the European Council was formalised as an institution in 2009 upon the commencement of the Treaty of Lisbon. Its current president is Charles Michel, former Prime Minister of Belgium. Scope While the European Council has no legislative power, it is a strategic (and crisis-solving) body that provides the union with general political directions and priorities, and acts as a collective presidency. The European Commission remains the sole initiator of legislation, but the European Council is able to provide an impetus to guid ...

Guadalquivir
The Guadalquivir (, also , , ) is the fifth-longest river in the Iberian Peninsula and the second-longest river with its entire length in Spain. The Guadalquivir is the only major navigable river in Spain. Currently it is navigable from the Gulf of Cádiz to Seville, but in Roman times it was navigable to Córdoba. Geography The river is long and drains an area of about . It rises at Cañada de las Fuentes (village of Quesada) in the Cazorla mountain range ( Jaén), flows through Córdoba and Seville and reaches the sea at the fishing village of Bonanza, in Sanlúcar de Barrameda, flowing into the Gulf of Cádiz, in the Atlantic Ocean. The marshy lowlands at the river's mouth are known as " Las Marismas". The river borders the Doñana National Park reserve. Name The modern name of Guadalquivir comes from the Arabic ''al-wādī l-kabīr'' (), meaning "the big river". There was a variety of names for the Guadalquivir in Classical and pre-Classical times.

Environmental Protection
Environmental protection is the practice of protecting the natural environment by individuals, organizations and governments. Its objectives are to conserve natural resources and the existing natural environment and, where possible, to repair damage and reverse trends. Due to the pressures of overconsumption, population growth and technology, the biophysical environment is being degraded, sometimes permanently. This has been recognized, and governments have begun placing restraints on activities that cause environmental degradation. Since the 1960s, environmental movements have created more awareness of the multiple environmental problems. There is disagreement on the extent of the environmental impact of human activity, so protection measures are occasionally debated. Approaches to environmental protection Voluntary environmental agreements In industrial countries, voluntary environmental agreements often provide a platform for companies to be recognized for moving beyond ...

Sewage Sludge Treatment
Sewage sludge treatment describes the processes used to manage and dispose of sewage sludge produced during sewage treatment. Sludge treatment is focused on reducing sludge weight and volume to reduce transportation and disposal costs, and on reducing potential health risks of disposal options. Water removal is the primary means of weight and volume reduction, while pathogen destruction is frequently accomplished through heating during thermophilic digestion, composting, or incineration. The choice of a sludge treatment method depends on the volume of sludge generated, and comparison of treatment costs required for available disposal options. Air-drying and composting may be attractive to rural communities, while limited land availability may make aerobic digestion and mechanical dewatering preferable for cities, and economies of scale may encourage energy recovery alternatives in metropolitan areas. Sludge is mostly water with some amounts of solid material removed from liquid sew ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Water, Energy And Food Security Nexus
The water, energy and food security nexus according to the Food And Agriculture Organisation of the United Nations (FAO), means that water security, energy security and food security are very much linked to one another, meaning that the actions in any one particular area often can have effects in one or both of the other areas. These three sectors (water, energy and food security nexus) are necessary for the benefit of human well-being, poverty reduction and sustainable development. As the world population is nearing 8 billion, increasing demands for basic services also rise, such as the growing desires for higher living standards and the need for more conscious stewardship of the vital resources required to achieve those services and these desires have become both more obvious and urgent. Water-food-energy connections lie at the heart of sustainable, economic and environmental development and protection. The demand for all three resources continues to grow for various reasons: a g ...

Sustainable Development Goal 6
Sustainable Development Goal 6 (SDG 6 or Global Goal 6) is about "clean water and sanitation for all". It is one of 17 Sustainable Development Goals established by the United Nations General Assembly in 2015, the official wording is: "Ensure availability and sustainable management of water and sanitation for all." The goal has eight targets to be achieved by 2030. Progress toward the targets will be measured by using eleven indicators. The six "outcome-oriented targets" include: Safe and affordable drinking water; end open defecation and provide access to sanitation, and hygiene, improve water quality, wastewater treatment and safe reuse, increase water-use efficiency and ensure freshwater supplies, implement IWRM, protect and restore water-related ecosystems. The two "means of achieving" targets are to expand water and sanitation support to developing countries, and to support local engagement in water and sanitation management. In 2017, 2.2 billion people lacked safely mana ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Population Equivalent
Population equivalent (PE) or unit per capita loading, or equivalent person (EP), is a parameter for characterizing industrial wastewaters. It essentially compares the polluting potential of an industry (in terms of biodegradable organic matter) with a population (or certain number of people), which would produce the same polluting load. In other words, it is the number expressing the ratio of the sum of the pollution load produced during 24 hours by industrial facilities and services to the individual pollution load in household sewage produced by one person in the same time. This refers to the amount of oxygen-demanding substances in wastewater which will consume oxygen as it bio-degrades, usually as a result of bacterial activity. Equation and base value A value frequently used in the international literature for PE, which was based on a German publication, is 54 gram of BOD (Biochemical oxygen demand) per person (or per capita or per inhabitant) per day. This has been adop ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Water Supply And Sanitation In The European Union
Water supply and sanitation (WSS) in the European Union (EU) is the responsibility of each member state, but in the 21st century union-wide policies have come into effect. Water resources are limited and supply and sanitation systems are under pressure from urbanisation and climate change. Indeed, the stakes are high as the European Environmental Agency found that one European out of ten already suffers a situation of water scarcity and the IEA measured the energy consumption of the water sector to be equivalent to 3,5% of the electricity consumption of the EU. Directives The water policy of the European Union, EU is primarily codified in the following European Union directive, directives: * The Bathing Waters Directive (76/160/EEC) of 1976 replaced by the Directive 2006/7/EC; * The Urban Waste Water Treatment Directive (91/271/EEC) of 21 May 1991 concerning discharges of municipal and some industrial waste waters; * The Water Framework Directive (2000/60/EC) of 23 October 2000 c ...

Anaerobic Digestion
Anaerobic digestion is a sequence of processes by which microorganisms break down biodegradable material in the absence of oxygen. The process is used for industrial or domestic purposes to manage waste or to produce fuels. Much of the fermentation used industrially to produce food and drink products, as well as home fermentation, uses anaerobic digestion. Anaerobic digestion occurs naturally in some soils and in lake and oceanic basin sediments, where it is usually referred to as "anaerobic activity". This is the source of marsh gas methane as discovered by Alessandro Volta in 1776. The digestion process begins with bacterial hydrolysis of the input materials. Insoluble organic polymers, such as carbohydrates, are broken down to soluble derivatives that become available for other bacteria. Acidogenic bacteria then convert the sugars and amino acids into carbon dioxide, hydrogen, ammonia, and organic acids. In acetogenesis, bacteria convert these resulting organic aci ...

Biogas
Biogas is a mixture of gases, primarily consisting of methane, carbon dioxide and hydrogen sulphide, produced from raw materials such as agricultural waste, manure, municipal waste, plant material, sewage, green waste and food waste. It is a renewable energy source. Biogas is produced by anaerobic digestion with anaerobic organisms or methanogen inside an anaerobic digester, biodigester or a bioreactor. Biogas is primarily methane () and carbon dioxide () and may have small amounts of hydrogen sulfide (), moisture and siloxanes. The gases methane, hydrogen, and carbon monoxide () can be combusted or oxidized with oxygen. This energy release allows biogas to be used as a fuel; it can be used in fuel cells and for any heating purpose, such as cooking. It can also be used in a gas engine to convert the energy in the gas into electricity and heat. Biogas can be compressed after removal of carbon dioxide and hydrogen sulphide, the same way as natural gas is compressed to CN ...

Sludge
Sludge is a semi-solid slurry that can be produced from a range of industrial processes, from water treatment, wastewater treatment or on-site sanitation systems. For example, it can be produced as a settled suspension obtained from conventional drinking water treatment, as sewage sludge from wastewater treatment processes or as fecal sludge from pit latrines and septic tanks. The term is also sometimes used as a generic term for solids separated from suspension in a liquid; this 'soupy' material usually contains significant quantities of 'interstitial' water (between the solid particles). Sludge can consist of a variety of particles, such as animal manure. Industrial wastewater treatment plants produce solids that are also referred to as sludge. This can be generated from biological or physical-chemical processes. In the activated sludge process for wastewater treatment, the terms "waste activated sludge" and "return activated sludge" are used. In food processing and bevera ...
