Abstract In this study, we attempted to develop a cost-effective activated carbon (AC) from local tea waste. AC was synthesized via pyrolysis process and used it treat tannery waste-water. A methylene blue adsorption test then conducted determine the highest capability of AC. The crystal structure microstructure were examined by X-ray diffraction (XRD) scanning electron microscopy (SEM). An ave...

In order to investigate the effect of growth media and nutrition method on the growth of Bellis perennis L. and nutrients uptake, a factorial experiment was conducted with two factors: growth media (municipal waste compost, Azolla compost, tea wastes compost) and nutrition method (without fertilizer, soil application, foliar spray) in comparison to the control medium (60% soil + 20% manure + 10...

Some industrial wastewaters contain high quantities of non-toxic salts besides heavy metal ions. The presence of salt ions leads to a high ionic strength of water, which may significantly affect the performance of the biosorption process, so that the effect of salts on the biosorption of heavy metal ions should be investigated. In this study the effect of different salts concentrations (0.1; 0....

Little information is available on the effects of applying compost tea to species in dry regions. Compost from agricultural waste can promote drought resistance in plants and increase their growth by improving soil structure and providing nutrients and enhancing the capacity of the soil to store moisture. In order to examine these effects, compost tea was tested on two species growing in dry re...
