HAA removal by GAC adsorption
AND YUEFENG F. XIE aloacetic acids (HAAs) and trihalomethanes (THMs) are the major disinfection by-products (DBPs) found in chlorinated drinking water. Nine species of HAAs are commonly found in chlorinated water: monochloroacetic acid (ClAA), monobromoacetic acid (BrAA), dichloroacetic acid (Cl2AA), bromochloroacetic acid (BrClAA), dibromoacetic acid (Br2AA), trichloroacetic acid (Cl3AA), brom...
متن کاملRemoval of Dye by Adsorption: A Review
Dye removal from industrial wastewater is an important environmental concern. So far, various physical and chemical treatment methods have been reviewed for the removal of dyes such as biological degradation, ion exchange, chemical precipitation, reverse osmosis, coagulation, flocculation, etc. However, these treatment processes have their limitations such as high cost, generation of toxic slud...
متن کاملRemoval of heavy metals from aqueous solution by sawdust adsorption.
The adsorption of lead, cadmium and nicel from aqueous solution by sawdust of walnut was investigated. The effect of contact time, initial metal ion concentration and temperature on metal ions removal has been studied. The equilibrium time was found to be of the order of 60 min. Kinetics fit pseudo first-order, second-order and intraparticle diffusion models, hence adsorption rate constants wer...
متن کاملRemoval of phenol from water by adsorption-flocculation using organobentonite.
Bentonite modified with short chain cationic surfactant might be the basis of a new approach to removing organic pollutants from water. The treatment process involves dispersing bentonite to the contaminated water and then adding a small cationic surfactant so as to result in flocs which are agglomerates of organobentonite and bound organic pollutants. The flocs are then removed from the soluti...
متن کاملCharacteristics of Organics Removal by Pact Simultaneous Adsorption and Biodegradation
-The use of powdered activated carbon treatment (PACT), based on simultaneous adsorption and biodegradation, is effective for treating organic toxic pollutants, present in industrial wastewaters. Removal of phenol and aniline from aqueous solutions by biological treatment alone, by adsorption on powdered activated carbon (PAC) alone and by simultaneous adsorption and biodegradation were compare...
