in this research, the effects of the addition of powdered activated carbon (pac) into the aeration zone of an activated-sludge (as) system for treating tehran oil refinery effluent, was investigated during more than 12 months in a pact pilot-scale model. besides the evaluation of organics removal efficiency and determination of basic design factors kinetic coefficients, a series of experiments ...
Backgrounds and Objectives: Powdered Activated$ carbon is known as a suitable absorbent for organic materials. The aim of this research is evaluation of Powdered Activated-Carbon (PAC) efficiency in removal of Dissolved Organic Carbon (DOC) in water treatment in Isfahan.Materials and Methods : The increase of PAC for DOC reduction has done in three paths in the Isfahan water treatment plant (WT...
Background and Aim: Activated carbon is a most common adsorbent. By emerging of new technologies, the activated carbon production methods need to be improved. The aim of this study was producing powdered activated carbon from Peganum Harmala seed under ultrasound waves for activation and its application for chromium removal from aqueous solutions. Materials and Methods: This experimental stu...
Background & Aims of the Study: High concentration of nitrogen compounds in water and wastewater can be caused various problems and diseases such as methhemoglobinemia and eutrophication. The aim of this study was investigated nitrification and denitrification from wastewater using integrated fixed film activated sludge (IFAS) includes powder activated carbon. Materias and Methods: The labo...
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...
