Furthermore, a major environmental challenge for wastewater treatment is the disposal of excess sludge produced during the process. Safe and long term solutions for the destination of sludge produced by wastewater treatment plants are a vital element of a sustainable functioning facility. The recycling of sludge, containing useful organic matter and nutrients in agriculture is considered as the best solution. In other hand, some more modern treatment technologies are even able to reduce the burden of sludge by lowering its production. Activated sludge treatment has many challenges that one of the biggest being the footprint it demands.
When we say water there’s a lot of type of water in the world, some people might think of sea water, water in the lake/river, some might think of dirty water. There is no doubt that water is important for living things. We not only can use it, and all living things need water to live. The importance of water is clear to us, it has many ways to use and we can’t overlook it. Not water that we need but what we need is clean water, water that has been filtered by the factory and 100% sure that is not going to give you disease.
has naturally increased because of the rapid expansion of the human race. The sizes of cities are increasing day by day summing up to an increase in sewage, cleaning, construction and manufacturing. These activities lead to over consumption and contamination of water. Water pollution, Air pollution and Land pollution have really had a hard impact on water as toxic wastes from industries/factories and mining activities get transferred to local water bodies. Some people throw their trash into rivers and lakes nearby and also wash themselves in the same water leading to unhygienic water and an increase in disease.
Water Pollution is one of the most major issues that exist in our world today. The main cause of water pollution is the humankind. If we keep on constantly polluting our water bodies such as lakes, oceans and rivers, there will be barely any clean water left on the earth. The long term impacts of water pollution is huge and can cause many problems to the future generation. Many People feel that it is time that they as a whole community take a stand to end this issue before it too late.
Water pollution is one of the main problems of today’s society. Inorganic and organic contaminants release from various industries represents a serious threat to environment due to their accumulation throughout the food chain. Human as final consumer is more sensitive to such pollutants, since biomagnifications of contaminants occurs at each successive trophic level. Conventionally used methods became expensive and require aggressive conditions that may lead to generate secondary pollutants. Therefore, worldwide there is a continuous interest in development of new, effective and inexpensive techniques for the removal of pollutants.
The water we drink is an essential ingredient for our wellbeing and a healthy life. Unfortunately polluted water and air are common throughout the world. Polluted water consists of sewage water and industrial discharged heavy metal effluents which cause damage to human health or the environment. Let me tell explain about the causes of water pollution. First of all, the first cause of water pollution is sewage water.
Conflicts among various users of water are increasingly over issues involving water quality as well as water quantity. Natural water bodies are able to serve many uses, including the transport and assimilation of waterborne wastes. But as natural water bodies assimilate these wastes, their quality changes particularly it degrades. If the quality drops to the extent that other beneficial uses are adversely affected, the assimilative capacities of those water bodies have been exceeded with respect to those affected uses. Water quality management measures are actions taken to ensure that the total pollutant loads discharged into receiving water bodies do not exceed the ability of those water bodies to assimilate those loads while maintaining the levels of quality specified by quality standards set for those
Health and safety concerns are the fundamentals considerations of water purification technology. Water purification is the process of eliminating contaminants from water, generally adopted to obtain water that is fit for human consumption. Water purification technology has also been adapted for a variety of other applications, not limited to pharmacological, medical and industrial needs. The most common purification techniques include physical processes such as filtration and distillation, biological processes such as slow sand filters and chemical processes like chlorination and flocculation (“Water Purification Technologies”, 2016). Clean and readily available water is essential for public health.
The human world can live with sewage, strewn beaches, dead oceans and rivers and fish that are hazardous to eat. Or all humans can work together to keep the environment clean and safe for the plants, animals and people who depend on it to remain healthy. Apart from the role of scientists, legislators, industries, and citizen groups, individual acts can also be taken to reduce water pollution such as using environmental friendly detergents, stopping pouring oil down drains, reducing pesticides and so on. Community action can be taken too, by helping out on beach cleans or litter pick to improve the cleanliness of our rivers, lakes and seas. By working together solutions for water pollution can be gained and water pollution can be controlled; thus leading the world to become a cleaner, less polluted and a better
(Rahman, 2013) In countries like India, which have growing economy and growing population, the increasing burden of waste produced creates major issues, with discharge of untreated sewage being one of the most important reason for water pollution. The major environmental challenges are related not only with waste disposal, but also with waste generation, waste transport and its treatment. Municipal solid waste disposed haphazardly and contamination of water is directly related to health of humans and animals, and is the source of various water borne diseases in environment. The environmental pollution can contain or aggravate the spread of these diseases and cause adverse situations and health problems like diarrhoea , typhoid ,
