Due to the rising water deficit in agriculture, digestate is increasingly being considered not only as an alternative fertiliser but also a potential source of water. The use recycled for crop irrigation requires that it be treated such way contaminants from fermented biomass are returned environment. Membrane processes can provide promising results this regard. This study seeks achieve membran...

This paper describes the basics of photocatalysis on semiconductors, mainly on TiO2 and the application of photocatalytic processes to water purification from organic matter. The second chapter is devoted to metal cocatalysts introduced in order to improve the photocatalytic action of titania. Finally, a short review of more interesting practical applications of the processes is presented.

background wastewater effluent in hospitals has been increasing during the recent decades due to developments in medical services and products. objectives this study aimed to investigate the qualitative parameters of effluent wastewater in hospitals affiliated to babol university of medical sciences (bums). materials and methods four hospitals were included and their wastewater effluent was stu...

waste water from a molasses alcoholic fermentation plant (mww) was treated biologically with phanerochaete chrysosporium. the ability of this white-rot fungus to degrade the dark colored pigments present in mww and the consequent decrease the effluent's color was examined. the optimum concentration of mww for color removal was determined and set at the ratio of 1:10. the color changes during in...

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...

Ceramic waste is most commonly produce from ceramic industry, this waste is in the form of pest and hard form, pest waste is known as the filter waste or slurry waste, which is produced at the end of polishing and finishing of ceramic tiles. The paper discuss that ceramic slurry waste powder is replaced by cement in concrete. Concrete grade M25 was made by replacing by 0% to 30% of Ordinary Por...

The current paper presents an institutional analysis of wastewater (non) treatment and reuse scenario using the case study of Hyderabad, India. The objective of the institutional analysis in the current study is to determine the extent and the character of an observed gap between declared rules (formal) and rules-in-use (informal practices) in the context of wastewater disposal, use and its adv...

Bioenergy is a type of renewable energy made from biological sources including algae, trees, or waste from agriculture, wood processing, food materials, and municipalities. Currently, the uses of renewable fuels (bioethanol, biodiesel, biogas and hydrogen) are increased in the transport sector worldwide. From an environmental and resource-efficiency perspective biogas has several advantages in ...

Introduction Utah’s wetlands provide a constellation of recreational opportunities, from sailing to photography, fishing to birdand wildlife-watching, hunting to picnicking. Even more important are the roles wetlands play in the functioning of Utah’s ecosystems. These roles include flood control, maintenance of groundwater quality and levels, pollution control, water purification, and the provi...
