metabolized and un-metabolized forms. Consequently, they reach receiving-surface waters since conventional wastewater treatment systems are inefficient (Zuehlke et al., 2004; Daughton, 2007). Pharmaceutical products available to the United States (U.S.) population are categorized under prescription and over-the-counter medications. Worldwide, many chemicals have been detected in wastewaters, effluents and freshwater ecosystems. For example, several chemicals were reported for UK estuaries (Thomas

straight pipe discharge and substantial impacts of water quality in local streams and tributaries. In Wilcox County, approximately 60% of surveyed unsewered households had a visible straight pipe surface discharge of raw wastewater and only 7% of households had a permitted onsite wastewater treatment system. For the remaining 33% inspection could not determine whether the discharge was above or below ground but there was no evidence of a septic system drainfield or a mound system (often this indicates

diseases. Pollutants are usually related to the sources of pollution. There are many sources of pollution, such as urban, industry and, recently, wastewater treatment pollution. The urban wastewater concerns houses and commercial enterprises. This pollution is increasing because of the growth of population. The chemical products rejected include in wastewater is important source of contamination. Although used water is taken by the sewage, an important part is dragging in the streams. This issue provokes

Wastewater treatment systems are very important to providing clean, drinkable water to its surrounding societies. These systems also help in the removal of contaminants in wastewater from household sewage, runoff, domestic, commercial and institutional units. Processes include physical, chemical and biological manipulation of contaminants to neutralize their effects on the human body for consumption. There are three main types of treatment, primary, secondary and tertiary, all of which have separate

The Wheaton Sanitary District is already using a state of the art monitoring system to track status and record the measurement of the key plant operational equipment. The Supervisory Control and Data Access (SCADA) system interfaced with the plant equipment provides, the operation team, a real time data on the key components of the plant 's equipment. SCADA allows operational team to open, close or adjust equipment parameters to archive maximum efficiency to meet the peak demand. According to Russell

treatment facility before distribution. LEGAL/POLICY ISSUES: There are also many legal issues that will need to be addressed. Taking additional measures to This Nuclear Plant in Arizona uses recycled water for cooling purposes. clean our wastewater and provide distribution back to the public will require large amounts

water asset shortage, populace development, contamination of surface and groundwater by releasing poisonous wastewater and ensuing maladies may raise the need of reusing and treatment of wastewater. The expelling of poisonous overwhelming metal particles from sewage, particularly in modern and mining waste effluents, has been generally examined as of late. Substantial metals wastewaters are specifically or in a roundabout way released into the earth progressively, particularly in creating nations

access to an improved source of water supply, and about 750 million do not have access to improved sanitation. Progress in rural areas appears to lag behind what has been achieved in urban areas. There are also operational problems. For example, many wastewater treatment plants do not operate properly, thus limiting the positive impact of the major investments made on the environment.

Conventional Sewage Treatment plants are the most common system for wastewater treatment in the United States. These systems are found in all urban communities but only in a few rural communities. This complex system is responsible for processing of the waste of the majority of the people in the United States yet few of them understand the scientific principles involved with treatment. In addition many people are even unaware of where their wastewater goes after it has been flushed down the toilet or disappear

Microbial Fuel Cells use bacteria to convert waste into electrical energy. These bacteria break down almost any biodegradable organic waste including sewage and water waste and use it as fuel to generate power. Places like Penn State University and The Biodesign Institute in Arizona State University are already testing and improving this new alternative energy. According to Penn State University they have achieved in producing 1.5 watts per meter squared of amount of waste water taken in and believe
