Recent advances in wastewater treatment processes have resulted in high removal
efficiencies for various hazardous pollutants. Nevertheless, some technologies are more …

Heavy metals like arsenic, copper, cadmium, chromium, nickel, zinc, lead, and mercury are
major pollutants of fresh water reservoirs because of their toxic, non‐biodegradable, and …

Industrial activities that consume water generate wastewater as a by-product of processing
which introduces various contaminants such as heavy metals into the neighbouring water …

The present era is seeking our attention on the dilemma caused by the contamination of the
aquatic system with chromium (Cr) and nickel (Ni). Amid Ni and Cr oxidation states …

Various techniques such as physical, chemical, biological, advanced oxidation and
electrochemical are used for the treatment of industrial effluent. The commonly used …

The need of the hour relies on finding new but sustainable ways to curb rising pollution
levels. The accelerated levels of urbanization and increase in population deplete the finite …

The term ''heavy metal''refers to any metal and metalloid element that has a relatively high
density ranging from 3.5 to 7 g cmÀ3 and is toxic or poisonous at low concentrations, and …

The word “electrocoagulation”(EC) will be sometimes used with “electroflotation”(EF) and
can be considered as the electrocoagulation/flotation (ECF) process. Through the process of …

In this study Response Surface Methodology (RSM) was employed to investigate the effects
of different operating conditions on the removal of hexavalent chromium (Cr (VI)) by the …

A combined two-step EC–EF process was designed to simultaneously remove Cr (VI) and
fluoride from pretreated acidic semiconductor effluents. The EC step comprises integrated …
