Advanced wastewater treatment requires highly efficient substrates, able to insure in a single step process the water discharge requirements. The paper the results obtained in the simultaneous removal of heavy metals and dyes, using a composite powder of fly ash and activated carbon. The results show that adding a small amount of activated carbon in a powder mixture with modified fly ash is highly effective in removing cadmium from wastewaters also containing dyes (methylen blue or methyl orange). Chemisorption is the likely mechanism governing this process.

Removal Of Heavy Metals

In the Present investigation various activated carbon derived from waste material of plant has been synthesized .These carbon materials have high porosity .This high degree of porosity of adsorbents is associated with large surface area, which makes it an excellent adsorbent for removal of Heavy Metals. The activated carbon has advantages over the other with respect of its adsorption capacity, operating Characteristic &Cost. The activated carbon materials have been characterized by surface area, particle size, bulk density, Volatile matter, Moisture content, Ash content, FTIR &SEM studies. The goal of the present investigation was an attempt to develop low cost, highly effective and simple to use activated carbon materials for removal Cr(VI), Cd(II) and Zn(II) from contaminated water based on adsorption phenomenon. This newly developed adsorbent has been proved to be more promising for heavy metals removal without affecting the quality of treated water.

Metals Removal

Heavy metals from the electroplating wastewater might cause environmental pollution if not well treated. Generally, carbon adsorption might be used for the final step for further trace metals removal. This study investigated the heavy metal Cu adsorption in the fixed bed column with 1, 10 and 100 mg/L influent concentration. Results showed that KAB decreased as influent Cu concentration increased from 1 to 100 mg/L while N0 increased as influent concentration increased from 1 to 100 mg/L as can be found in Adams-Bohart model. R2 was found between 0.8579 and 0.9182. In Thomas model. KTH and q0 showed the similar trend as KAB and N0 in the Adams-Bohart model. KTH decreased as influent Cu concentration increased from 1 to 100 mg/L. q0 increased as influent Cu concentration increased from 1 to 100 mg/L. R2 of regression model was found between 0.9065 and 0.9836. In Yoon-Nelson model. KYN increased as influent Cu concentration increased from 1 to 100 mg/L while τ decreased as influent Cu concentration increased from 1 to 100 mg/L. Results showed that the three models of Adams-Bohart model, Thmoas model and The Yoon-Nelson model were suitable for the description of Cu adsorption by activated carbon.
