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 from homes, industries, agricultural farms and even storm water. It is made up of various components that range from large objects (papers and plastics) to fine solids from human waste and even tiny organisms such as germs and bacteria. In Trinidad, wastewater is collected at numerous Wastewater Treatment Plants and is treated before being released back into the environment. Treatment of wastewater is necessary because clean water is critical to plants and animals that live in water. Rivers and oceans serve as habitats for different species of fish and other aquatic life. Migratory water birds such as pelicans and ducks use the areas for resting and feeding. Water can carry diseases and since human life depends on water for survival therefore it is necessary to have clean water.
If wastewater is not properly treated, then the environment and organisms can be negatively impacted. The impacts can include harm to fish and wildlife populations, oxygen depletion, restrictions on recreational wa...

...led water is most commonly used for nonpotable (not for drinking) purposes, such as agriculture, landscape, public parks, and golf course irrigation. 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 habitats.

Essay on The Wastewater Treatment Of Wastewater Reclamation

- Reclaimed wastewater or reuse water is defined as an effluent that is derived from any part of the sewage facility that has been sufficiently and reliably treated to meet the water quality suitable for beneficial use without sludge handling or pollutants discharging. The wastewater can be classified in two main categories: domestic waste (residence, commercial, and institutional waste) and industrial waste which contains different types and strengths of contaminants from the domestic one, as these contaminants had been generated during the production process for any industrial facilities....   [tags: Water, Sewage treatment, Water pollution]

Recycling Processes for Wastewater Essay

- 1.0 INTRODUCTION Recycling water in Canada is an important issue to understand and implement because of its wide ranging benefits in environmental matters. Canadian wastewater can be recycled by water treatments, each of these treatments results in varying water qualities, and these varying water qualities can be reused for industrial, unrestricted access or restricted access uses. Recycling wastewater is a crucial part of sustainable development; however, many communities in Canada are not active participants of this subject....   [tags: Canada, water treatment, environment]

Essay on Wastewater Treatment: Primary and Secondary Treatment

- CHAPTER-3 3.1 Introduction As the given situation describes, eutrophication is a result of the presence of nitrogen and phosphorus in river since no protection methods are carried out to end the release of waste into the water bodies. Such rivers are commonly known as sensitive rivers. These nutrients excite the production of algae providing food for their growth under the accurate circumstances thus causing eutrophication. Eutrophication can harm the ecosystem causing unwanted alteration in aquatic population, extreme reduction of oxygen, health issues to human-beings and animals, expensive water treatment costs and, interfering with recreational signifi...   [tags: microorganisms, organic waste]

Wastewater Treatment And Its Effects On The Environment And Public Health

- Wastewater, also known as sewage, is a mixture of domestic and industrial wastes. It is 99.97 percent water, and the remainder contains organic matter such as human waste and food scraps, fats, oil and grease, debris, household chemicals, and industrial waste that can pose a threat to the environment and public health (1). As a result, effective treatment of wastewater is crucial to minimize the environmental impacts of wastewater. Wastewater treatment is carried out in several stages, which resulted in the separation of wastewater into sludge and a dissolved fraction of water, organic materials, bacteria and salts (2)....   [tags: Water, Sewage treatment, Water pollution, Oxygen]

Sewage Should Be Broken Down Into 99.9 % Water Essay

- Sewage can be broken down into 99.9% water and 0.1 % solids as the solids 70% of its organic substance (protein, carbohydrate, and fats) and another 30% is inorganic (grits, salts, and metals) and that is a typical municipal wastewater analyses. Based on this, chemical and bacteriological components of the treated/discharged effluent into receiving water body should be monitored to ensure the safety of the public health according to the effluent limitations (NPDES permits). Therefore, a TMDL will identify the amount of an exact or property of a pollutant weather from point, nonpoint, or natural sources that may be discharged to a water body and still ensure that the water body gains water qu...   [tags: Sewage treatment, Water pollution, Wastewater]

The peculiar physical-chemical properties of these chemicals contribute to a more complex behaviour in aquatic environments. The main path for the discharge of these compounds in the environment are wastewater treatment plants (WWTPs), notably know in being inefficient in remove these contaminants during conventional treatments. Most approaches to evaluate the concentration of these substances in WWTPs are based in national consumption estimative, which can with reasonable significance predict overall discharges [1], however are not to be suita...   [tags: wastewater, environment, results, issues]
