Performance Evaluation of Combined Process of Powdered Activated Carbon-Activated Sludge (PACT) in Textile Dye Removal
Introduction: The Powdered Activated Carbon Treatment (PACT) has been proposed as an alternative in wastewater treatment and wastewater biomass protection against toxic substances. This study aims to evaluate PACT performance in treating dyes, acid orange, and remazol brilliant reactive blue. Materials and Methods: This empirical- applied research was carried out in pilot scale in which differ...
متن کاملinvestigation of hexavalent chromium removal from aqueous solution using granular and powdered activated carbon produced from peganum harmala seed
background and objectives: because of toxical and hazardous properties of hexavalent chromium (cr(vi)), its removal by an economical and efficient method is necessary. the use of activated carbon, as an adsorbent, is a common and effective method for hexavalent chromium removal. thus the aim of this study was to produce granular and powdered activated carbon form peganum harmala and compare the...
متن کاملperformance of a powdered activated carbon (pac) augmented activated sludge process treating semi-aerobic leachate
semi-aerobic leachate is characterized by organic matter (cod, bod) which is relatively low in concentration and difficult to biodegrade. in conventional treatment systems, the low biodegradability is attributed to partial stabilization of leachate at the landfill. biological treatment of leachate in malaysia is not well established and any important data for the treatment process is not availa...
متن کاملRemoval of Hexavalent Chromium Ions from Aqueous Solution by Adsorption Using Activated Carbon Prepared from Cucumis Melo Peel Activated carbon
Activated carbon prepared from Cucumis Melo Peel was used as adsorbent for the removal of chromium ion from aqueous solution. Adsorption experiments were performed by varying initial metal ion concentration, temperature, and pH. Freundlich and Langmuir isotherms were used to analyze the equilibrium data obtained at different adsorption conditions. Adsorption results obtained, shows that the Cr ...
