Desalination Literature Reviews Samples For Students

Seawater Pretreatment Process

Desalination or treatment of seawater is a process in which fresh water that is suitable for consumption is extracted from the saline water (Pearce, 2007). Many methods are used in the desalination process, but the most applied and efficient one are reverse osmosis. The sea water that is fed to the reverse osmosis plants, many times has large particles which end up spoiling the membranes of the plants due to the high level of large particles in the seawater (Van Hoof, Hashim, & Kordes,1999). Therefore, to reduce operation cost and treatment time, there is a need for a pretreatment ...

LITERATURE REVIEW: WATER TREATMENT

1.0 Literature Review: Water Treatment.
1.1 Water Quality:
Water quality is the measure of water condition in relation to the requirements of various biotic species, the environment, and/or any human needs and purposes. Water quality is determined by measuring and analyzing it chemical, biological, physical and radiological characteristics. Both natural and human activities influence water quality. Natural influences that affect water quality are mainly climatic, geological and hydrological since they affect both the quality and quantity of water available (Diersing 2009). The highest influence on water quality occurs when its quantity is low, yet the limited resource must be ...

Abstract

Water is the most important source of life. Survival of any living organism without water is impossible. Though a large part of the earth is constituted of water, the supply of fresh water is limited to only 3% of the total amount of water found on the earth's surface. With the demand for fresh and clean water rising across the world, it is time for us to think seriously about the importance of water conservation. There are several engineering and behavioral practices which, if adopted by us at home, industries and other spheres of work and life, can reduce the ...

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

Membrane filtration is a technique used to separate a liquid from any particles present in it. In membrane filtration, a liquid is passed through a semi-permeable membrane. The size of the pores on the membrane determines its permeability thereby enabling the membrane to act as a barrier to all particles larger than the pore sizes. Different approaches and systems can be employed in membrane filtration depending on the type and capacity of the liquid being purified but the overall goal is to obtain a clean liquid. Membrane filtration can be used in the treatment of wastewater, filtering milk during its processing among other applications. This ...
