Abstract
Wastewater is simply water than has been used from industries, domestic and ground water run-off. It usually contains various pollutants, depending on what the water was used for. The wastewater is treated to improve and purify the water by either removing some or all of the pollutants. After treatment, the water is fit for reuse and discharge back to the environment. The act of making the wastewater fit for reuse is recycling. Not only does reusing waste water benefit humans economically, it also assists in sustaining the quality of the environment.
Introduction
Wastewater is water that is considered to be below the standard of suitable quality for the environment by humans. This type of water originates from a mixture of used water

The impacts can include harm to fish and wildlife populations, oxygen depletion, restrictions on recreational water use such as beach closures and fishing, and contamination of drinking water. The major aim of wastewater treatment is to remove as much of the suspended solids as possible before the remaining water, called effluent, is discharged back to the environment. As solid material decays, it uses up oxygen, which is needed by the plants and animals living in the water.
Effects of wastewater pollutants
Environment Canada provides some examples of pollutants that can be found in wastewater and the potentially harmful effects these substances can have on ecosystems and human health:
• Decaying organic matter and debris can use up the dissolved oxygen in a lake so fish and other aquatic biota cannot survive;
• Excessive nutrients, such as phosphorus and nitrogen (including ammonia), can cause eutrophication, or over-fertilization of receiving waters, which can be toxic to aquatic organisms, promote excessive plant growth, reduce available oxygen, harm spawning grounds, alter habitat and lead to a decline in certain species;
• Chlorine compounds and inorganic chloramines can be toxic to aquatic invertebrates, algae and

Other nonpotable applications include cooling water for power plants and oil refineries, industrial process water for such facilities as paper mills and carpet dyers, toilet flushing, dust control, construction activities, concrete mixing, and artificial lakes.
Conclusion
In addition to providing a dependable, locally-controlled water supply, water recycling provides tremendous environmental benefits. By providing an additional source of water, water recycling can help us find ways to decrease the diversion of water from sensitive ecosystems. Other benefits include decreasing wastewater discharges and reducing and preventing pollution. Recycled water can also be used to create or enhance wetlands and riparian
Use of pesticides & other fertilizers infuse nitrogen oxide into the water bodies acidifying the water which kills the plants and aquatic animals living in
...wastewater is sewage plants or sewers, since many areas dump their sewage in the ocean. Sewage does have nutrients like nitrogen and other things some organisms may need to grow.
Water is an essential part of life for any living organism in the world. People use water every day to drink, do daily housework, or to bathe in; while animals use water to survive. Because of the doings of humans, the water that is so essential to all organisms’ well being is being polluted. The water drink and use every day may have oil from large petroleum companies spilling into it. Debris from sewer plants float into the ocean when they overflow. Even prescription pills are contaminating the water. Not only is the water affecting the humans that drink it but also affects the aquatic life. Aquatic species may have problems reproducing which disrupts the whole food chain and biodiversity web of life. How water becomes contaminated should
our pipelines and sewers where it goes to a treatment plant to be treated, but
With recent developments in plumbing technology, it is quickly becoming easier than ever to be mindful of water conservation. Through the use of greywater technology, and easy methods of rainwater collection, the demand for freshwater required within the home can be greatly reduced.
Phase one in process of waste water treatment begins in the home, local businesses and community. Waste water from these buildings and surrounding areas travel through a pipe, or sewer which is sloped downward, and with the assistance of gravity, travels toward the waste water treatment plant. However, in larger communities or communities with unevenly leveled terrain, waste water cannot keep getting deeper to rely on gravity to transport the waste water and must pumped up by the assistance of a lift station so it may continue to travel to the water treatment plant. Once the waste water arrives at the waste water treatment plant, the first step is the removal of large debris such as diapers, underwear or other non-biological...
Today's waters are constantly being treated like sewage dumps or trash cans. We use them as garbage cans every day polluting the water more and more. "Pollution is often by way of rivers, drains and outflow pipes." Causing an outflow of sewage into our ocean waters. This is not only affecting the community but also the marine life and other sea creatures living in the ocean." This pollution includes human sewage and domestic waste water, factory outflows of acids and poisonous metals, engine oil from roadside drains and garages, farm chemicals washed off the land by rain, building-site rubble, nuclear waste from power plants, and oil from wells, refineries, and tankers." Stating that most of today's waste is from factory or factory ran products that shouldn't be polluting the water
Above all, these organisms encourage the growth of algae, which absorb dissolved oxygen in the water essential for the survival of fish populations. Occasionally, the decomposition of newly-submerged biomass and sediment further reduce the water's oxygen content. Water sources can literally choke to death as a result of increasing human activity, such as industry and agriculture giving rise to increased nutrient loading.
The process of disposing waste, producing food, and purifying bodies of water is useful today. For example, communities that live in the desert, like in the southwestern United States and in the Middle East, can use this process to farm and survive. They can use the newly purified water for their crops or for their own consumption. In addition, when algae purifies water, it releases oxygen.
lines, rope, and plastic nets are being caught in the rutter and the engine, but
Domestic households and industrial and agricultural practices often produce wastewater that can cause rivers and lakes to become polluted. This is typically called sewage and wastewater pollution. Sewage is a term for wastewater that usually contains feces, urine, and laundry waste. With there being billions of people on earth, treating sewage is a big priority. Untreated sewage can contam...
Wastewater is the combination of water-carried or liquid wastes starting in the sanitary conveniences of dwellings, industrial or commercial facilities. In addition to this, surface water, groundwater and storm water may also be present. It is any water that has been badly affected in quality by anthropogenic influence. It contains waste from residential, industrial and commercial processes. Municipal water contains industrial wastewater, sewage and gray water. Gray water is the water from sinks and showers. Large industries also produce wastewater.
Therefore, many countries in the developed world have adopted recycling policies for disposal Of waste. The benefits of the recycling process include the following. Maintaining the cleanliness of the environment in the first place from the damage of burying and burning the waste or leaving it exposed Reduce the pollution of sea, ocean and river waters from dumping solid waste, threaten marine life, and reduce groundwater pollution from the waste of
Water plays such an important role in our daily lives. 70% of our body is composed of water. 70% of the earth surface is also made up of water, but out of the 70%, only 1/3 of water is consumable. In fact, this amount has been continuously to decrease as more and more industries began to pollute and damage the water. For example, many toxic chemicals may be released into the water thus making the water impure. Such pollutions and damages lead the water to be contaminated and inconsumable as it may cause severe diseases. Water purification can remove all the unnecessary bacteria and viruses from the water that is hazardous for our health. Water purification may also improve the flavor and appearance of water. It removes the unpleasant odor. Therefore, water purification became one of the most useful and popular process used by people all over the world today. It is by far the most recommended and safest water treatment that is commonly used to purify damaged water into consumable water. Water purification provides us with safe, pure and clean water to consume and use.
