Adsorption of methylene blue from aqueous solution using tea waste in a continuous stirred tank reactor (cstr)

In these past few decades, huge numbers of technologies have been developed for wastewater treatment. The scale of these technologies is also very diverse, from a basic aeration pond, to a more sophisticated nanotechnology based treatment system. In this research, dye removal from aqueous solution b...
