- What are the most effective waste treatment options prior to discharge to receiving bodies of water or the local wastewater treatment facility. Paint manufacturers, to include Sherwin-Williams, produce a variety of different paint types and colors, including both organic solvent-borne and water-borne paints. Each type and color of paint is manufactured in a separate batch, and all manufacturing equipment is generally cleaned between batches to prevent contamination (figure 1-1). This equipment cleaning process is the largest source of waste from paint manufacturing and can account for up to 80% of a paint manufacturer’s waste stream (WMRC, 1992)....

- ... Also in this process, there is no special method employed during the treatment cycle to remove heavy metals from wastewater. 1.2 Nitrogen, Phosphorus and Heavy metal Contamination 1.2.1 Nitrogen and Phosphorus Contamination (a) Sources Conventional wastewater treatment can remove phosphorus and nitrogen concentrations in wastewater to a limited extent . Discharge of this untreated water leads to high release of nitrates and phosphates into the environment. Agricultural activities are significant contributors for release of nitrates and phosphates to the groundwater in most parts of the United States.... [tags: pollution, environment, technology]

- The presence of phosphorus (P) in natural systems such as rivers or lakes is target of great research interest because excess phosphorus can causes ecological damage like eutrophication. This excess of phosphorus can came from different sources, for example, loading from wastewaters treatment plants, agricultural or urban runoff. This is why different investigation has focus in modeling phosphorus loadings and transport in these natural systems. Although they differ from each other for the different parameters involved like the morphological data depending on the type of system, the sources of the excess phosphorus (point sources: effluent wastewater treatment plants or diffuse sources:...

- The treatment of surface wastewater is aimed at bringing contaminated water back to its previous state for domestic use or otherwise. Some of the sources of wastewater include industrial effluents from manufactures, agricultural effluents, agro-industrial as well as domestic wastewater from sinks, bathtubs, toilets, and so on. Particles in the water from the various sources include bacteria, organic matters, and sand which cause the water to be turbid or discoloured in appearance and have an unpleasant odour....

- Hydric Soils as a Part of Water Treatment in Wetland Systems Most basically, a hydric soil is defined as "A soil that is saturated, flooded, or ponded long enough during the growing season to develop anaerobic conditions in the upper part (Kent, 1994, p. 26)." Included by this definition in the United States Department of Agriculture/Soil Conservation Service's list Hydric Soils of the United States are all of the poorly drained and very poorly drained soils and most of the somewhat poorly drained soil series....

- The United States and Mexico share a 2000-miles border stretching from the Golf of Mexico to the Pacific Ocean. The border region is shared by ten states, wetlands, numerous mountain ranges, canyons, rivers and deserts. The U.S.-Mexico border is “Situated between a developed nation and a developing one, the U.S. -Mexico Border Region is a formally defined transnational region of land. The region extends approximately 2,000 miles along the full length of the international boundary, 62.5 miles (100 kilometers) north and south of the border and 62.5 miles into the Pacific Ocean and Gulf of Mexico.” The economic, political and social changes continue reshaping the relationship between the two n...

- ... Organic nitrogen is derived from inorganic sources including nitrite (NO2-), nitrate (NO3-), nitric acid (HNO3), ammonia (NH3), ammonium (NH4+), and nitrogen gas (N2). Microalgae has an ability to convert inorganic nitrogen be only in the forms of nitrite, nitrate and ammonium to organic nitrogen through a process called assimilation. Only eukaryotic algae can perform assimilation . Figure 2.2 describes the assimilation process of inorganic nitrogen. As shown in the figure 2.2, translocation of inorganic nitrogen takes place across the plasma membrane where reduction of nitrate takes place followed by the incorporation of ammonium into amino acids and glutamine....

- 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...

- 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]

- The world today is faced with a lot of different waste problems. One major problem is how to get rid of the waste safely so that it does not disrupted the environment or hurt people or animals. The major problem for the United States is waste water, the amount, and the cost of treatment and disposal. The United States treats over 1 billion tons of waste a year. How do we treat that much waste. One way it to send the waste water into a treatment plant ran by the state or county. The water contains solid particles, which mixed with the untreated water is called sludge.... [tags: Papers]
