Essays on Effluent

Our company is a leading designer and manufacturer of water and wastewater treatment systems. We provide systems designed as per client’s requirements, and statutory treated effluent standards. Most of our projects thus involve detailed engineering drawings of various physical tanks, and mechanical parts such as clarifier rotating arms, air floatation systems, pumps, piping, control panels etc. Appropriate process flow diagrams and layouts are thus essential part of proposals and quotations. Thus, it is essential that we prepare our plant diagrams with respect to ASME Y14 standards. The ASME Y14 are standard codes developed by the American Society of ...

1. Intake with screen removes floating, large solid impurities. The removed solids are called screenings, and they are treated and disposed as solid wastes. Mixing tank is where coagulants such as alum, aluminium sulfate, ferric chloride, ferrous sulfate or lime are mixed with raw water (Al-Najar), there is no waste stream generated from mixing tank since the process is quick and there is no time to settle. In, the flocculator slow mixing occurs to allows for floc formation, the chemicals added in mixing tank promote this process. Flocculated suspended impurities settle sooner due to their large size and mass. ...

Material Extraction of Dry Battery AA:

A typical alkaline dry AA cell comprises a cylindrical external case, cathode, anode, and electrolyte and separators. The external casing is made from nickel-plated steel and is lined with a separator to divide the anode and cathode. The separator is made of either a porous synthetic material or layered paper. On one end, the battery canister is sealed with an epoxy or asphalt sealant underlying a steel plate and at the other end with a brass rod driven through the cylinder. The rod is welded to a metallic end cap and passed via an outer plastic seal. Inside the ...

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 ...

Hydraulic fracturing or fracking is a process of oil and natural gas extraction from underground rock formations such as shale, by injecting a mixture of high-pressure water with chemicals and sand through a well drilled through various layers of earth (US Environmental Protection Agency [EPA], ES-1). Wastewater generated from fracking is usually concentrated with various pollutants, and has to be treated before disposal. Further as the hole is drilled through layers of earth, there is possibility of new contaminants entering the water table due to disturbance. Also, if groundwater is tapped in excess, pollutants from the gas production well ...

Introduction

Industries in West Virginia have violated the state-issued permit of pollution by releasing toxic substances such as coal ash and selenium into the local water supply. In addition to the threat toxic substances like coal ash and selenium pose to the health of the community, toxic water destroys the environment and destabilizes the local ecosystem of the areas impacted by such pollution. West Virginia Department of Environmental Protection (WVDEP) was formed as a guidance tool to aid persons to know when it is environmentally secure to withdraw water from the stream. This judgment is built on percentages of yearly ...

Water Pollutant - Phosphate

Phosphates are nutrients essential for plant as well as animal growth. But, when their concentration exceeds certain limit they pose serious problems to water bodies, and adversely affect water quality. Major sources of phosphates are non-point sources that include agricultural run-off and sewage or domestic effluent (West Cumbria Rivers Trust, 2015). Phosphate fertilizers used in agriculture are washed off during rains, and they reach nearby water bodies. Sewage receives phosphates from detergents and food or drink additives (West Cumbria Rivers Trust, 2015). Excess phosphates in the water body lead to algal bloom or “eutrophication” that completely destroys the quality ...

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 ...
