Milad Mousazadeh,Elnaz Karamati Niaragh,Muhammad Usman,Saif Ullah Khan,Miguel A. Sandoval,Miguel A. Sandoval,Zakaria Al-Qodah,Zaied Bin Khalid,Vishakha Gilhotra,Mohammad Mahdi Emamjomeh +9 more
TL;DR: A comprehensive review of the available recent literature utilizing EC to treat wastewater with high COD levels is presented in this paper, where recommendations are provided for future studies to improve the EC technology and broaden its range of application.
Journal ArticleDOI
Electrochemical treatment of high strength chrome bathwater: A comparative study for best-operating conditions
Vishakha Gilhotra,Rekha Yadav,Aditi Sugha,Laxmi Das,Ashutosh Vashisht,Rajbir Bhatti,Manpreet S. Bhatti +6 more
TL;DR: In this article, high strength chromium wastewater was treated by electrochemical and chemical precipitation, and the results showed that 97.5% chromium removal efficiency was achieved under optimized process conditions, i.e. pH 5, current density 68 A/m2 and treatment time 17
Journal ArticleDOI

TL;DR: In this paper , the authors provide an overview of emerging electrochemical technology for oil-containing wastewater treatment with a overview of the origin and characteristics of oily wastewater, and some recommendations for future improvement trends of the EC method are presented.
Journal ArticleDOI
Comparison of ambient air pollution levels of Amritsar during foggy conditions with that of five major north Indian cities: multivariate analysis and air mass back trajectories
Rekha Yadav,Manpreet S. Bhatti,Sushil Kumar Kansal,Laxmi Das,Vishakha Gilhotra,Aditi Sugha,Dipti Hingmire,Shweta Yadav,Ankit Tandon,Rajbir Bhatti,Anubha Goel,Tuhin Kumar Mandal +11 more
TL;DR: In this article, multivariate data analysis, along with air mass trajectory analysis, was used to explain the complex behaviour of ambient air quality during winter fog, where wind speed and visibility during fog events were studied along with prevailing wind direction for major PM episodes.
