Phragmites australis activated carbon production to remove dissolved solids from irrigation water

Due to the high ability of Iran for producing Activated Carbon and the Fact that (1) it is not produced in the power from with particle size of lower that 100 nm in the country, (2) to production in the power from is not suitable, (3) high necessity for it and (4) its high in ports to the country, the production of activated carbon with good adsorption properties are very important. For producing activated carbon, different raw materials need to be used. In the investigation study, cheap and available phragmites australis were used. By physical activation, activated carbon was produced and then the effect of activated carbon on reducing dissolved solid was investigated. Carbon and activated carbon samples of phragmites by using pilot-scale furnace in the laboratory were produced. Additionally, the effect of each process variables such as adsorbent material (carbon and activated carbon), the mass of adsorbent and concentration of dissolve solids on the absorption capacity, production efficiency and absorption properties of carbon and activated carbon were investigated. Then the optimum production conditions were determined. The results showed that phragmites australis was cheap material with suitable physical properties for activated carbon producing, and that the activated carbon has higher adsorption capacity than carbon. For the removal of dissolved from water.
