Organic matter from biofilter nitrification by high performance size exclusion chromatography and fluorescence excitation-emission matrix

A combination of high performance size exclusion chromatography with organic carbon detector and ultraviolet detector coupled with peak-fitting technique and fluorescence excitation-emission matrix spectrometry applied fluorescence regional integration method was conducted to determine the characteristics of organic matter during nitrification. The batch scale of bionet nitrification without or...

کارایی راکتورهای بیوفیلمی بستر متحرک حاوی کالدنس نوع 1 در حذف ترکیبات آلی و ازته تحت شرایط محدود اکسیژن محلول از فاضلاب

  Background: Moving bed biofilm reactor (MBBR) is one of the new hybrids biological systems that are used in treatment of wastewater contaminated by organic and nitrogen pollutant. In this study, the continuously operated laboratory scale Kaldnes(k1) moving bed biofilm reactors (MBBRs) was investigated.   Methods: In this system, two series as Anoxic reactor (R1) and aerobic (R2) have a size 3...

Investigating the efficiency of chemical coagulation/Electro-Fenton process in the removal of organic matter from pharmaceutical industry wastewater

Background and Objective: Wastewater from pharmaceutical industry has high chemical oxygen demand as a result of the presence of organic drugs and antibiotics. In order to meet the environmental requirements, several treatment methods like chemical and electrochemical methods have been widely applied due to their high ability to remove organic compounds from pharmaceutical wastewater. Therefore...

Application of wastewater with high organic load for saline-sodic soil reclamation focusing on soil purification ability

Fresh water source scarcity in arid and semiarid area is limitation factor for saline-sodic soil reclamation. The reusing of agricultural drainage and industrial wastewater are preferred strategies for combating with this concern. The objective of current study was evaluation in application of industrial sugar manufacture wastewater due to high soluble organic compounds in saline-sodic and sodi...
