Background : 2-chlorophenol is one of the aromatic organic compounds found in large amounts in oil and petrochemical waste waters and chemical methods such as advanced oxidation, etc are used for removal there. Among various AOPs the method derived from sulfate radicals (SO4● -) and per sulfate (S2O82-) activating with heat, UV radiation and transition metals (such as iron ions) is of interest....

Background and Objective: Olive Mill Wastewater (OMWW) is one of the most polluted sanitary wastewaters that its ineffective treatment will cause severe pollution of the environment. In this study, OMWW treatment wasinvestigated using combined electrocoagulation and novel advanced oxidation process. Materials and Methods: Biodegradability, efficiency and kinetics of removal of turbidity and or...

Backgrounds and Objectives: The base structure of total petroleum hydrocarbons (TPH) is made of hydrogen and carbon. Widespread use, improper disposal and accidental spills of this compounds lead to long term remaining of contaminations such as organic solvents and poly aromatic hydrocarbons (PAHs) in the soil and groundwater resources, resulting in critical environmental issues. In this s...

Background & Objectives: Entering LAS through the wastewater plant’s effluent to water resources causes taste and odor changes, aquatics death, oxygen transfer limitation, and disorders in water treatment processes. Therefore, the study objective was to determine optimum conditions for fenton oxidation process to remove linear alkyl benzene sulfonate from aqueous environments using taguchi meth...

Introduction and purpose: Treatment of dye wastewater produced by textile industries is a major challenge for the environment. About 15% of the total produced dyes in the world are released in sewages during dyeing activities. Alizarin red S (ARS), a synthetic dye produced from Alizarin sulfonate is the most widely used dye in the textile industry. The aim of this study was ...
