Wastewater is any water that has been adversely affected in quality by anthropogenic influence which can originate from a combination of domestic, industrial, commercial or agricultural activities, surface runoff or storm water, and from sewer inflow or infiltration. Based on Samorn Muttamara (1996) wastewater characteristics could be identified by physical, chemical, and biological parameters. Physically, fresh waste water is usually grey in water and industrial waste water may contain many colouring substances. Odours in wastewater usually are caused by gases produced by the decomposition of organic matter. Industrial wastewater may contain either odorous compounds or compounds that produce odours during the process of wastewater treatment. …show more content…

This can be proven by the article of ‘The Industry in Perspective’ written by Vikram Rao (2015), which he claimed that usually flowback water will be reused in shale oil and gas well for fracturing to reduce the needs for fresh water whereas the unusable wastewater will be discharged into deep injection wells.

There are numerous studies done by the researchers to treat the waste water in an efficient ways and cost effective manners. For example, (Rattanapan et al., 2011) used dissolves air floatation-coagulation technology to treat the biodiesel wastewater. While, (Ramireze et al., 2012) used photo-fenton-aerobic sequential batch reactor and (Romero et al.,2013) used electrofloatation and electrooxidation technology to treat the biodiesel wastewater. Each of technology produced different quality of wastewater treatment based on the COD removal, BOD removal, SS removal and O&G removal aspect.
In addition, study conducted by (Wahi et al.,2013), he found that sorption is the best method for secondary treatment to remove the oil and grease content in the wastewater. He also claimed that natural sorbents from either mineral or organic provenance have the additional advantage of low cost and environmental friendliness to provide good O&G removal

    Due to the Water Pollution Control Act of 1970, there are stringent standards that need to be considered when depositing wastewater from the process. It was not possible to show the path that the wastewater would take after leaving the system, however, the pollution standards were considered. The water that was produced in the reaction were present in streams with other components such as CO2, butadiene, and maleic anhydride. Due to this exposure, the separated water will be sent to a waste water treatment plant where it will undergo many steps to ensure that the pollutants have been properly removed (Plant Design Book

    Hundreds of chemicals are used during Marcellus Shale drilling; therefore, the process can cause contamination and pollution. According to Marc Levy and Mary Esch, because the Marcellus Shale drills go so far under the ground, the water there has a higher chance of being polluted. According to the article “Methane Gas and Its Removal from Wells in Pennsylvania” methane is a chemical that can contaminate drinking water because of drilling. Too much methane can be harmful to humans (Swistock and Rizzo). According to the article “Hydrofracking,” water sources also have an increased risk of being polluted when a drill is installed near them. Some of the contaminated wastewater that this process creates stays in ...

  • How Unethical Is Hydraulic Fracturing?

    The amount of water required and the different chemical additives used in the frac fluid is what poses a threat to the safety, health and welfare of the public. Hydraulic fracturing uses concoction of slush water, sand and chemicals combined with pressure to stimulate to either create or expand cracks in the shale. One of the main concerns is the large amount of fresh water used and lost in todays fracturing techniques. Certain fracturing techniques can use to 8 millions gallons of water, either freshwater or treated produced water. This freshwater makes up about 98% to 99% of the total volume of the slush (fracfocus.org). After the frac is done the w...

    Conflicting reports make it difficult to discern just how detrimental the practice is to the environment and people. What is known is that fracking uses phenomenal amounts of water, which is becoming a scarce resource in many parts of the country. There is no doubt that the fluid used in the fracking process contains chemicals, and when released into water supplies, has negative effects on these sources. Injection of flowback materials into deep wells has been definitively linked to increased seismic activity.

  • Fracking rough draft

    534 Words  | 2 Pages

    Fracking is a fairly new drilling technique that uses a form of horizontal drilling through the earth to retrieve oil at certain depths. Once it breaks the surface of the ground, a “well” is drilled vertically down until the desired depth is reached. Once there it proceeds to make a 90 degree turn and will begin to drill horizontally for several thousands of feet where they believe the natural gas is. From there a mixture of water, sand, and various chemicals are pumped into the well at exceedingly high pressures. According to clean water action, “This is done to create fissures in the rock in which the gas can escape through” (“All about fracking” 1). Once the gas escapes through the fissures, it is pulled back up to the surface. There they proceed to process the oil, refine it and then ship it to the market. However the process is not over. The “wastewater” returns to the surface and is held in large steel tanks until a long-term waste solution can be reached.

  • Case Study of Waste Water Treatment Plants

    Waste water treatment plants are essential to communities of all sizes and must work efficiently. Waste water treatment plant primary priority and responsibility is the treatment of incoming sewage water by the removal of biological and chemical wastes so it can be treated and recycled for future use. There are many government agencies and standards set forth to govern and observe the successful treatment of sewage such as: the Department of Environmental Quality, the National Pollutant Discharge Elimination System and the Clean Water Act of 1972. Compliance and constant monitoring of the treatment plant’s operations are important; as they protect the surrounding community. A spill or backflow of sewage due to a complete system malfunction could potentially be detrimental to the environment and local community. A precise system, of which must be compliant according to government standards, is critical to maintain low levels of wastes that are returned to neighboring water systems after treatment.

    Clean Water: “An under-appreciated liquid to Survive” Water is pure and transparent liquid that is vital for all humans, plants and animals on the planet. In the United States, people have access to clean drinking water and clean sanitation systems, not like in other parts of the world where clean, safe drinking water is getting scarce. A lot of people don’t have access to it, and many regions are suffering severe drought. Yet, when humans take it for granted, they don’t appreciate that a reliable, clean supply of water is essential to human health, economy and agricultural prosperity. Having clean and safe potable water is a right, and not a privilege.

    Drug manufacturing industries discharge significant quantities of organic compounds, solvents such as Methanol, Acetone, Toluene, Ethanol, Ethyl Acetate etc. and inorganic solids such as Sodium, chloride, sulphates, silica etc. Usually the concentration of COD in the waste water produced by the pharmaceutical industry is around 5000 – 15000 mg/L, the concentration of BOD5 is relatively low, and the ratio of BOD5/COD is lower than 30% which means the wastewater has a poor biodegradability. Such wastewater has a bad color and high (or low) pH value, and it needs a strong treatment method.
