Water-filled light pipes can be used to transport concentrated beam solar radiation from a solar collection system to a utilization system, altering the spectral distribution of the radiation in a beneficial way in the process. One use for such a system would be for the daylighting of the core interior spaces of buildings, spaces that are far removed from outside walls or the roof and are there...

conclusions the results of this study show that it is possible to remove nitrate, and its intermediates from waste water. regarding the desirability of the process, the field scale study is proposed. results the results showed that by applying electric current of 0.14 a for 120 minutes, the nitrate content would reduce down to 97%. the obtained r2 for the nitrate removal model was higher than 0...

This paper presents the treatment of Acid green V by an electrochemical oxidation using Ti/RuO2 IrO2 TiO2 as anode and cathode and NaCl as supporting electrolyte in a tubular flow reactor under continuous single pass process. During the electrolysis, COD reduction, color removal, and energy consumption were investigated under different flow rates and current densities. The experimental results ...

In China, with the rapid urbanization and industrialization, and highly accelerated economic development have resulted in degradation of water resource. The water quality deterioration usual result from eutrophication in most cases, so how to dispose this type pollution water higher efficiently is an urgent task. Hower, different with traditional technology, constructed wetlands are effective t...

Abstract Batik is one of Indonesia’s original cultural heritages. In Indonesia, the batik industry largest home-based textile industry. This consumes a large amount water. Due to unavailability wastewater treatment plant, most producers dispose directly into river, resulting in extensive water pollution. Some pollutants, such as color, phenol, and sulfide, have potential pollute environment. Wa...

Abstract Drinking water is a sole element of human life. The rapidly growing population adding to the excessive demand for water. Increasing drinking rising over-exploitation Raw sources require treatment with high production capacity treatment. Present research provides case study plant Kekri, Rajasthan, India. In these two plants purification efficiency good as compared conventional plants. A...

In Mexico, the manufacturing of mezcal generates huge amounts of mezcal vinasses (MV), that cause a negative environmental impact. Although there is no specific information for mezcal vinasses, similar effluents have been treated by anaerobic digestion (AnD) usually complemented by oxidative chemical post-treatments such as ozonation. In the present work the post-treatment of anaerobically pret...
