background: desalination plants have an important role in providing community drinking water. the increasing trend of water consumption and decrease of natural resources of fresh water make this role even more important. the aim of this study was to evaluate the quality of inlet and outlet water of desalination plants by reverse osmosis (ro) process in qeshm, iran and also to compare the qualit...

The results presented in this paper are part of a project aimed at designing an original solution for the treatment of used disposable diapers permitting the recycling of materials and the recovery of energy. Diapers must be collected separately at source and transported to an industrial facility to undergo special treatment which makes it possible to separate plastics and to recover a biodegra...

The Brookhaven Medical Research Reactor was a 5 mega-watt, light-water cooled and heavygraphite moderated research facility. It has two shutter-equipped treatment rooms, three horizontally extended thimble tubes, and an ex-core broad beam facility. The three experimental thimbles, or activation ports, external to the reactor tank were designed for several uses, including the investigations on d...

Waste streams associated with a variety of agricultural runoff sources are major contributors of nutrients, pesticides and enteric microorganisms to surface and ground waters. Water soluble anionic polyacrylamide (PAM) was found to be a highly effective erosion-preventing and infiltration-enhancing polymer, when applied at rates of 1-10 g m(-3) in furrow irrigation water. Water flowing from PAM...

introduction: giardia and cryptosporidium are two of the most common parasitic protozoa that cause acute intestinal infections in children, all of the world. these parsites find in water environments, such as untreated water , wastewaters and even treated water. according to, a precise study on surface water was not done, in our country, necessity of precise study by ifa method that is prescise...

in this study a sample of bentonite obtained from semnan mines, was modified by a surfactant to prepare an organoclay with high surface area. bet analysis showed that the modification increased its surface significantly. the prepared sorbent was used for removal of dyes and other organic pollutants from a waste water obtained from ekbatan textile company. adsorption was studied in various times...

The solar chimney power facility has the potential to become a valuable technology for renewable energy production. Its financial viability depends on a thorough understanding of the processes affecting its performance, particularly because of the large startup costs associated with facility design and construction. This paper describes the potential impacts on plant capacity resulting from clo...

The international society focuses on the environment protection and natural energy sources control for the global cooperation against weather change and sustainable growth. The study presents the overview of the water shortage status and the necessity of wastewater reuse facility in military facilities and for the possibility of the introduction, compares the economics by means of cost-benefit ...

The Umgeni Water Wiggins water treatment plant feeds the southern areas of Durban in South Africa and has a maximum treatment capacity of about 350 Ml/d. Two interconnected reservoirs at this facility hold treated water before it enters the distribution network. Because of the variable demand, the reservoir levels and residence times undergo considerable variation. This has a strong influence o...
