Introduction:
Water is crucial for all aspects of life, the defining feature of our planet. Ninety seven and a half per cent of all water is found in the oceans, of the remaining freshwater only one percent is accessible for extraction and use. Functioning and healthy aquatic ecosystems provide us with a dazzling array of benefits – food, medicines, recreational amenity, shoreline protection, processing our waste, and sequestering carbon. At the beginning of the 21st century, the world faces a water crisis, both of quantity and quality, caused by continuous population growth, industrialization, food production practices, increased living standards and poor water use strategies. Wastewater management or the lack of, has a direct impact on the biological diversity of aquatic ecosystems, disrupting the fundamental integrity of our life support systems, on which a wide range of sectors from urban development to food production and industry depend. It is essential that wastewater management is considered as part of integrated, ecosystem-based management that operates across sectors and borders, freshwater and marine.

What is Waste water:
Wastewater, also written as waste water, is any water that has been adversely affected in quality by anthropogenic influence. It comprises liquid waste discharged by domestic residences, commercial properties, industry, and/or agriculture and can encompass a wide range of potential contaminants and concentrations. In the most common usage, it refers to the municipal wastewater that contains a broad spectrum of contaminants resulting from the mixing of wastewater from homes, businesses, industrial areas and often storm drains, especially in older sewer systems. Municipal wastewater is usually treated in a combined sewer, sanitary sewer, effluent sewer or septic tank.
Sewage is the subset of wastewater that is contaminated with feces or...

...Tourism Towards 2030, the tourism industry has grown to become one of the world’s fastest growing and largest economic sectors (United Nations World Tourism Ogranization, 2015). Traditionally the hospitality and tourism industry has not been viewed as one that has a large impact on the natural environment, especially when compared to industries such as oil, gas, and consumer product manufacturing industries. However, hotels contribute to negative environmental impacts through energy and water usage, importing non-durable goods, as well as emitting a large amount of carbon dioxide. Hotel water consumption for laundry, showers, toilets, dishwashers, swimming pools, spas, golf course irrigation, as well as for other amenities, can consume up to 1million m3 of water per year (Gössling, 2013). Global warming and water scarcity are both acknowledged around the world as serious problems, and with the demand for water expected to exceed supply by 40% by 2030, hotels must implement water waste management techniques and policies to help achieve sustainable tourism development (Tuppen, 2013). In 1995, an action plan for businesses in the travel and tourism sector was created by the World Travel & Tourism Council, the World Tourism Organization, and the Earth Council. These three international organizations created Agenda 21 for Travel & Tourism Industry: Towards Environmentally Sustainable Development (Stipanuk, 2015). Since then, many companies in the hospitality and tourism sector......

...Water Quality; Wastewater Management Water Treatment Charles E. Best, Jr TUI University BHE 314 / Module 3 Case December 22, 2010 Professor Dr. Nathaniel Ofoe With the United States growing and cities becoming larger and larger day by day, communities have been battling water shortages all throughout the country. For the past fifty or so years reclaimed water has been used all over the world. Within the course of this case paper I will attempt to compare and contrast the secondary water treatment methods to that of the tertiary water treatment methods. Wastewater treatment is classified as primary, secondary, and tertiary treatment; this is the process of how wastewater actually becomes recycled water. The primary treatment process is the initial stage or in other words the beginning of how organic and inorganic solids are removed via sedimentation and flotation. During this initial stage approximately 40-60% of suspended solids and raw sewage are collected in sedimentation tanks and 25-35% of the biochemical oxygen demand (BOD) is removed from the waste stream. During the secondary treatment the out flowing from the primary treatment process contains residual organic and inorganic material. Secondary treatment systems will remove between 80-95% of suspended solids and (BOD) through two methods known as attached growth and suspended growth. Finally we are at the tertiary treatment process also known as the polishing process where......

Waste Management and Disposal

...agency decree of 1988 includes water, air, land and all plants and human beings or animals living therein and the interrelationships which exist among these, or any of them e.g. waste. Two kinds of definitions are operative for waste. One is conceptual and the other descriptive (Savasi, 1977) and defines waste by listing the kinds of materials comprising it. In the conceptual sense, wastes are defined as useless, unwanted or discarded materials. However, to a modern environmentalist, waste are just materials which are discarded because, they ‘seem’ to have no further economic use ignoring the irrelevant issue of usefulness, value or desirability of the waste. In the descriptive definition, waste consists of discarded materials resulting from domestic, community activities, industrial, commercial and agricultural operations. 1.1 TYPES OF WASTE Agricultural waste, Biomedical waste, Business waste, Chemical waste, Consumable waste, Domestic waste, Industrial waste, Inorganic waste, Medical waste, Organic waste, Recyclable waste Toxic waste, etc. Population explosion, uncontrolled urbanization and rapid industrialization have caused high waste generation quantities and rates in a country, (NEST 1991) waste generation increases not only because people multiply and hence the space available to each person becomes smaller, but also because the demand per person are continually increasing, so that each person throws away more waste year by year.

Waste to Energy

...1. ABSTRACT Alternative uses of waste for energy production becomes increasingly interesting both from a waste management perspective - to deal with increasing waste amounts while reducing the amount of waste deposited at landfills and from an energy system perspective to improve the flexibility of the energy system in order to increase the share of renewable energy and reduce greenhouse gas emissions. The object of analysis is waste which is not reused or recycled, but can be used for energy production. Different Waste-to-Energy technologies are analyzed through energy system analysis of the current Danish energy system with 13-14% renewable energy, as well as possible future Danish energy systems with 43% (2025) and 100% renewable energy (2050), respectively. The technologies include combustion, thermal gasification, anaerobic digestion, fermentation, and transesterification technologies producing electricity, heat, or transport fuel. In the USA, according to the US energy recovery council, there are 87 WTE plants producing 2,700 megawatts that results into 17 million of kwh per year which is enough to meet the needs for power for 2 million households. In the EU incineration is more popular. According to the confederation of European Waste to energy plants (CEWEP) the plants in Europe can supply annually about 13 million inhabitants with electricity and 12 million inhabitants with heat. Waste to energy is produced mainly by biological material and thus the energy......

Issues in Australia

...manage its waste?” Australians are among the world's largest producers of waste. Each Australian produced about 1 tonne of waste, which goes to landfill every year, with only 4% of waste recycled or re-used. The millions of tonnes of waste disposal into the environment every year are symbolic of our presently unsustainable patterns of production and consumption. The disposal and management of that waste is now an important issue for governments throughout Australia. The volume of waste per person increased from 1,200 kg to 2,100 kg over a ten-year period Waste Management Waste management is one of the geographical issues concerns that arise due to the changes in the environment. Geographical issue surrounding wastes include: the type of waste and the disposed of it and using waste as landfill, which consume large areas of land. In developed countries such as Australia, waste can be directly linked to over consumption of natural resources. The impacts of Waste Management The impacts of waste management are considerable. There are many problems associated with waste that make it a significant environmental issue. Waste that is disposed of in landfills has the potential to contaminate soil and groundwater, and emit greenhouse and toxic gases into the atmosphere. When waste is disposed of through incineration or other means, its impacts upon the environment, and potentially on human health, are also significant. Moreover, the impact of waste management......

Soild Waste

...Urban Waste Management Solid wastes are those organic and inorganic waste materials produced by various activities of the society, which have lost their value to the first user. Improper disposal of solid wastes pollutes all the vital components of the living environment (i.e., air, land and water) at local and global levels. There has been a significant increase in MSW (municipal solid waste) generation in India in the last few decades. This is largely because of rapid population growth and economic development in the country. Due to rapid growth of urban population, as well as constraint in resources, the management of solid waste poses a difficult and complex problem for the society and its improper management gravely affects the public health and degrades environment. The population of Mumbai grew from around 8.2 million in 1981 to 12.3 million in 1991, registering a growth of around 49%. On the other hand, MSW generated in the city increased from 3200 ton per day to 5355 ton per day in the same period registering a growth of around 67% (CPCB 2000). This clearly indicates that the growth in MSW in our urban centers has outpaced the population growth in recent years. This trend can be ascribed to our changing lifestyles, food habits, and change in living standards. Waste referred as rubbish, trash, garbage, or junk is unwanted or unusable material. According to European councils’ directive “Waste is any substance or object which the holder discards or intends or is......

Bio Reactor Landfill - an Overview

...Solid Waste Management: An Overview Of Bioreactor Landfills Anusha John#, Ajay kumar K#, Abdul Shiyas M A#, Sreenath H# Department of Chemical Engineering, National Institute of Technology Calicut NIT Campus P O, PIN 673601, Kerala 1manjalyjohn@gmail.com 2ajaykumar@nitc.ac.in 3shiyas2003@yahoo.co.in 4srinad@gmail.com Abstract--- A landfill is a site for the disposal of waste materials by burial and is one of the most common methods of solid waste management in various parts of the world. Significant environmental and economic benefits can be gained by making small changes in the way the landfills are operated. Bioreactor landfill is a promising biotechnological option for faster stabilization of Municipal Solid Waste (MSW). It changes the goal of landfilling from the storage of waste to the treatment of waste. In a bioreactor landfill environment, the solid waste actively decomposes rather than being simply buried in a dry tomb. This active decomposition is possible because over half the MSW is comprised of organic material (food, paper, etc.), which will decompose fairly rapidly under the right conditions. Rather than being kept dry, the solid waste is actively moistened by injecting leachate into the landfilled solid waste to accelerate decomposition. The anaerobic conditions in a conventional landfill can be replaced with aerobic conditions by introducing air into the solid waste and thus enhancing the biological process. Studies show that a bioreactor......
