Interaction of natural organic matter (NOM) and the Fe0 process for treatment of copper - and zinc-contaminated roof runoff
نویسنده
چکیده
Fe barrier is a promising technology for the treatment of copper and zinc contaminated roof runoff. However, recent findings showed that Fe processes fell at some operational conditions, in which natural organic matter (NOM) is among the crucial factors contributing to a significant decrease in the treatment efficiency. The present work assesses the mechanisms involved in the interaction of NOM and the Fe processes for treatment of metals. Extensive characterization of NOM containing roof runoff samples have been carried out employing various methods including XAD4/8 adsorption resins, copper complexation, acidic capacity and liquid chromatography with online carbon detection (LC-OCD). The characterized results were used to describe the removal of Cu and Zn during the kinetic batch and during the flow-through configurations.

Removal of natural organic matter from aqueous solutions by electrocoagulation
Natural organic matter (NOM) affects some qualitative parameters of water such as color. In addition, it can deteriorate the performance of water treatment process including coagulation, adsorption, and membranes. NOM also reacts with chlorine in the chlorination process and may form disinfection by-products. The present study was carried out in laboratory-scale in a batch system using a cylind...

Background and Objective: Natural organic matters (NOM) are known as precursors to disinfection byproducts. As conventional treatment processes cannot get disinfection by-product standards, novel methods have been increasingly applied for the removal of disinfection by-products precursors. The UV/ZnO process is one of the advanced oxidation processes using photocatalytic technology. The present...

As a low cost byproduct, Actinidia deliciosa shell can be made into sorbent materials which are used in heavy metals immobilization. It has been investigated as a replacement for currently expensive methods of heavy metal immobilization from soil. In this study, soil samples were contaminated with copper (Cu) and zinc (Zn) at the rate of 600 ppm in separate dishes. The 5% Actinidia deliciosa sh...

Of the problematic agents in the ecosystem, heavy metals have special importance because they are unabsorbable and have physiologic effects on living beings at low concentrations. This study has investigated the effect of silk worm cocoon on reducing mobility of zinc (Zn) and copper (Cu) for the first time. To this end, 5% cocoon adsorbent was added to the studied soil, which had been contamina...
