A Review of Electrocoagulation Process for Wastewater Treatment
The control of environmental pollution and also the treatment of polluted water are of great concern. Within the past decade, electrochemical coagulation process has emerged as most effective wastewater treatment process as compared to conventional techniques of treating wastewater. Electrocoagulation is robust, cost effective, reliable, low sludge generating process, it has automation amenability and it has high pollutant removal efficiency. The aim of the review is to explain the basics and up to date advancement of electrocoagulation method for the improvements in the pollutant removal efficiency.

Advanced Wastewater Treatment By Nanofiltration And Activated Carbon For High Quality Water Reuse
Hybrid processes combining activated carbon and nanofiltration have been studied to identify the optimum solution for advanced wastewater treatment in high quality water reclamation and reuse. With a focus on the removal of bulk and trace organic compounds the investigation identified three promising process combinations, namely powdered activated carbon followed by nanofiltration (PAC/NF), granular activated carbon followed by nanofiltration (GAC/NF) and nanofiltration followed by granular activated carbon (NF/GAC). The removal potential was examined in lab and pilot scale for a range of refractory pharmaceuticals and industrial chemicals typically detected in effluent in trace concentrations ranging from ng/L to μg/L. Fluorescence excitation emission spectroscopy was employed for the investigation of the fate of effluent organic matter. The optimum strategies for operation of the hybrid processes were determined in pilot scale. The experiments were conducted at the Wastewater Treatment Plant Aachen Soers providing an effluent of high quality with low dissolved organic carbon (DOC) concentrations of about 5 mg/L.

Discharge quality from municipal wastewater treatment plants and the Sludge Biotic Index for activated sludge: integrative assessment
Abstract
Wastewater treatment plants (WWTPs) are scrutinized by Environmental Authorities particularly regarding the compliance to discharge limit values fixed by national and local regulations. An integrated approach is necessary to achieve the objectives established with Directive 2000/60/EC (WFD) considering the ecological status of the receiving water body and the quality of the discharge. Specifically, documentary, technical, management and analytical controls should be developed. Moreover, integrative information on the behaviour of the activated sludge in the aeration tank can be useful for plant managers as well as for the regulating Authorities. The study presents the experience concerning WWTP regulation considering the analytic assessment of the discharge as well the monitoring of the Sludge Biotic Index (SBI) for activated sludge. Data from monitoring during the period 2008–14 on SBI values and chemical and microbiological data on the discharges of a sample of 35 WWTPs in the province of Venice (north-east Italy, Veneto region) are presented and discussed. Together with chemical and microbiological analysis, the SBI appears to be a highly useful index for the integrative assessment of plant functionality, in particular when monitoring and identifying critical situations that can determine the exceedance of discharge limit values. The SBI method, in an integrated control approach, can be used for small and medium sized WWTPs that only treat domestic wastewaters. In a case by case assessment this may even substitute part of the analytical monitoring carried out in the WWTPs' control process.

A study on The Removal of Some Phenolic Compounds from Wastewater
ABSTRACT:
The removal by means of Advanced Oxidation Processes (AOPs) is an attractive option for the treatment of industrial wastewater containing phenolic compounds in an environmental . The present work would summarize some AOPs technologies focusing only on heterogeneous catalytic removal of phenol and highlighting the catalysts activity and reaction conditions. The catalysts used were H ZSM-5,H-Mordenite and Bentonite. H-ZSM-5,H-Mordenite doped with Platinum (Pt) were prepared and characterized by using X-ray diffraction analysis (XRD), thermal analysis, Scanning electron microscopy, High Resolution Transmission electron microscopy, pluse titration measurements, nitrogen adsorption desorption at -196°C. the experimental parameters affecting the removal efficiency were time, temperature, pH, initial phenol concentrations, catalyst dose and the effect of irradiating with Ultraviolet (UV –C) were studied . The optimum conditions for the removal of each catalyst were investigated .
