Effluent treatment of industrial wastewater using processed solid residue of olive mill products and commercial activated carbon

Abstract

:The carbonised solid residue of olive mill products, called J-carbon (0É6È0É7 mm), was compared with Sigma activated carbon (powder) and Chemviron activated carbon (0É6È0É7 mm) in treatment of the effluent of FlexsysÏ wastewater. The removal of TOC as non-speciÐc organics, and six speciÐc NH 3 , leading organic pollutants from FlexsysÏ wastewater effluent were examined.

Dye removal from wastewater using activated carbon developed from sawdust: adsorption equilibrium and kinetics

“…It is evident that the activated carbon prepared from mahogany sawdust is efficient to adsorb direct dyes from wastewater, the process attaining equilibrium gradually. This is due to the fact that activated carbon is composed of porous structure with large internal surface area [7,24,25]. Three consecutive mass transport steps are associated with the adsorption of solute from solution by porous adsorbent [26].…”

“…Among various treatment technologies, adsorption onto activated carbon has proven to be one of the most effective and reliable physicochemical treatment methodology [6][7][8][9][10][11]. However, commercially available activated carbons are very expensive.…”

Removal of methylene blue from aqueous solution using cotton stalk, cotton waste and cotton dust

“…For this purpose, many methods such as activated carbon sorption, chemical coagulation, ion exchange, electrolysis, biological treatments, etc have been developed [3,4]. Of these methods, activated sorption is highly effective for the removal of dyes and pigments as well as other organic and inorganic pollution [2,[5][6][7][8][9]. However, commercially available activated carbons are very expensive, and thus the use of activated carbon is not suitable for developing countries because of its high cost.…”

Current and potential uses of thermally treated olive oil waste

“…The ability of activated carbon, made from solid residue of olive mill products, to remove NH 3 , total organic carbon and some organic compounds comprising heteroatoms like sulphur and halogens from a wastewater treatment plant was examined by Gharaibeh et al. (1998).…”

“…The ability of activated carbon, made from solid residue of olive mill products, to remove NH 3 , total organic carbon and some organic compounds comprising heteroatoms like sulphur and halogens from a wastewater treatment plant was examined by Gharaibeh et al (1998). Batch reactors were filled with wastewater and activated carbon, and the materials have been mixed for 20 h. Batch experiments were also conducted in parallel using commercial types of activated carbon made from metallurgical grade coal and peat.…”
