Sewage is derieved from the latin word "exaquare" signifying 'to deplete out(water or other fluid substances) ' Waste water more often than not comprises of filthy water from showers, dishwashers, toilets and so on which incorporate human waste, cleansers, cleansers and other destructive microorganisms and non-biodegradable substances which hurt the earth after some time if not treated appropriately. Sewage is produced from
Reusing materials and products saves energy and water, reduces pollution, and lessens society‟s consumption of natural resources compared to the use of single-use products and materials. For example: Cardboard boxes that are used for shipping products can be folded and sent back to the manufacturer to be reused for shipping the same or other products. Cardboard boxes can also be recycled at paper mills, but in order to recycle the boxes water and energy are required. Paper recycling also generates sludge in the process,which need to be disposed of. Beverage bottles –soda or beer bottles– can be disposable, reusable.Reusable bottles have the lowest environmental impact of the three, while disposable bottles require the most energy, water and generate the largest amount of waste and pollution.
Recycling reduces the need to consume energy, which is important for large production, such as refining. Since the used materials have already been cleaned and processed once; the second time is taking much less energy. Secondly, it minimizes the global warming. I personally find it very important because if we can have even a little influence on our environment, I think we should try to do it.
Growth of aquaculture is becoming a major polluting activity in many countries. Irrigation return flows carry salts, Phosphorus, nitrogen, metals, pathogens, sediment, pesticides, salt, BOD1, trace elements (e.g. selenium). 6 nutrients and pesticides. Tile drainage rapidly carries leachates such as nitrogen to surface waters.
Municipal Solid Waste (MSW) can be defined as the useless production of human activities in term of non-liquid and non-gaseous which are in the form of biodegradable and non-biodegradable. (Etusim et al., 2013) Biodegradable municipal waste (BMW) is the degradable component of municipal waste which is commonly comprised of cardboard, papers, textiles, food waste, animal waste and garden waste that are not bio-stabilised waste. (Environment, Community and Local Government, 2007) These municipal waste contains 65% is biodegradable. However, biodegradable waste can be produced by homes and businesses which include ‘organic’ or natural materials and these materials can be decomposed over time by natural processes. (“National Strategy on Biodegradable
Sewage is a mixture of wastes, both domestic and industrial in the form of solution or suspension. It is also called municipal water or wastewater. It consists of nearly 99% water along with pathogenic bacteria, suspended solids and ions. It is released in water bodies like lakes or streams and there is a need to ensure the proper treatment of these wastes in order to prevent water pollution and related diseases. Sewage is derieved from the latin word ‘exaquare’ meaning ‘to drain out(water or other liquid substances)’ Waste water usually consists of dirty water from showers, dishwashers, toilets etc.
Pollution has been around for decades, for as long as the human race exists. With the migration of people and with the creation of cities the waste would pile up faster then it could be recycled by the nature. The main forms of pollution are: air pollution, water pollution and land pollution. When releasing carbon monoxide, sulfur dioxide, nitrogen oxides and so on we pollute air. The water is polluted when releasing different toxins and similar materials into the water.
Recharge by runoff from irrigation water into groundwater as well as leaching of agrochemicals cause serious groundwater contamination problems. The clearing of natural vegetation and ploughing up of virgin land for new cultivation also affect the groundwater quality. Irrigation is one of the major sources of salinity in the soil through which rainwater flows to the water table. The dissolution of these salts finally
The degradation process of biodegradable plastics releases substances that are less damaging to the environment when compared to that of the synthetic plastics thereby reducing the pollution. Biodegradable plastics have a variety of applications like in agriculture, food packaging, biomedical devices and tableware etc. The major obstacles in the path of replacing synthetic
One of the main type of sewage is domestic sewage. Domestic sewage means sewage directly from kitchen, bathroom, and laundry sources. It can come from waste from food preparation, dishwashing, garbage-grinding, toilets, baths and sink. Those things we mostly will all do in everyday and some time, if you don’t treat it well, it’s very deadly to water quality. Domestic sewage contains a wide variety of impurities.
