Essays on Wastewater Treatment

The extraction of oil and natural gas has been a major industry in the United States for many years. Originally, this fuel was used simply to heat homes. With the advancement in technology, many different types of machinery, including electrical generators at power plants, automobiles and home appliances have been designed to operate using natural gas. In recent years, it has become more difficult to find new sources of natural gas. Hence, various companies have ventured in hydraulic fracking in the hope of producing more natural gas. However, the hydraulic fracking itself brings a host of environmental and health ...

Abstract

The research is dedicated to studies of activated carbons performance in the wastewater treatment process of dye removal. The experiment was performed to assess the efficiency of the commercial activated carbons (F100, F600, F820, SGL 8×30, CAL, AP4-60, OLC12×30) in adsorption process for Dylon Burlesque Red removal. The effect of pH, type of activated carbon, dye, contact time, and salinity was studied. The experiments were performed by measuring the absorbances of the solutions before and after contact with the activated carbon. The absorbance was evaluated with UV-vis spectrometry. The adsorption of the dye took place on all ...

Edible oil refinement is one of the major problems faced by the developing countries across the world as edible oil effluents are a major source of environmental pollution. Owing to this, it is essential to ensure that the effluents are treated prior to its disposal. The composition, characteristics and quantity of the waste water generated depends on the operating conditions and processes followed and can vary from different organizations in the same industry. An investigative method comprising of an in-depth study of unit operations, monitoring, measurement and analysis of parameters affecting environment, and performance evaluation of utilities and pollution ...

Introduction

There are environmental chemical processes which require light to react. These processes are called photochemical reactions. Photochemical reaction is commonly initiated due to the absorption of solar energy or light. When molecules absorb energy in the form of light, the atoms are converted in a transient excited state (Larson & Weber, 1994). This transition state or excited has completely different physical and chemical properties with the initial state of the molecule. The excited states also have more tendencies to react since they are considered stronger acids and stronger reductants that the initial state of the molecule. The excited state of ...

Abstract

In most parts of the Arab countries, the limited resources of water pose adverse constraints to both the social and economic development, while also threatening the people’s livelihood. The available surface water keeps on declining, and the ground water over-pumping that goes beyond the natural recharge rates has continued to cause great negative impact in the lowering of water table. Over-pumping of ground water also increases ground water salinity, ground water depletion, and ecological degradation (SCENR 5). The outcome prompted the Qatar government to start regulating its water resources as a measure ...

Introduction

Mining activities can pose serious environmental and health implications. Although, these environmental and health hazards can be mitigated and effectively managed through sound engineering and environmental practices, these environmental and health issues associated with mining operations could not be totally eradicated. In general, there are three major players in the mining industry: the company, which include the employees and the stockholders; the regulatory bodies, which include the government and other national and international environmental organizations; and the community, which are not directly related to the mining industry, but is impacted by its operations. Each one of these stakeholders has ...
