conclusions it was shown that the removal efficiency of nitrate was directly proportional to the amount of chaff, temperature, and contact time but inversely to the ph. this study showed that nitrate removal by chaff is a promising technique. results the result of this study revealed that chaff as an absorbent could remove nitrate from solutions, and the efficiency of adsorption increased as co...

present study examines whether there is any beneficial effect of magnetized water application on seedling emergence of maize seeds. water from various sources like tap water, saline water (1,500 ppm), canal water, and sewerage water was treated magnetically by passing it through 235 mt magnetic fields at 3 lpm flow rate. seeds were soaked in water for 24 hours and planted in sand culture. numbe...

introduction: humic acid (ha) is one the original disinfection byproducts processors in water treatment. so, removing it is necessary before water chlorination. in the present study, photodegredation of humic acid in water using ag/zno nano particle under uvc irradiation in batch system was investigated. material and methods: photocatalytic study was carried out to evaluate the effect of uvc (1...

Reclaimed wastewater has become a potential water resource for many dry areas. Its recovery should be regarded as an additional stage in the water cycle providing a new water resource and preserving other high quality sources for more demanding applications. However, in this new scenario, a special attention should be paid to its physicochemical and microbiological quality to avoid damage to pu...

book through his lucid presentation of much technical data. The discussion of corrosive qualities of water is unusually thorough and explicit as is his discussion of the sanitary significance of impurities in water and on bacterial decomposition of organic matter in water. What might be considered to be a deficiency is the rather limited discussion of waterborne diseases. The liberal footnotes ...

This paper investigates the survivability of a water cleaning facility using Fluid Stochastic Petri Nets (FSPN). Water cleaning facilities are responsible for providing drinking water to a specific district. The provided service is very important and makes such facilities belong to a nation’s critical infrastructures. Therefore, such a facility should be able to recover in a timely manner after...

agricultural waste biomass generated from agricultural production and food processing industry are abundant, such as durian  peel, mango peel, corn straw, rice bran, corn shell, potato peel and many more. due to low commercial value, these wastes are disposed in landfill, which if not managed properly may cause environmental problems. currently, environmental laws and regulations pertaining to ...
