Could power plant waste help cut water pollution?

Green Walls Could Cut Street-Canyon Air Pollution

Rows of tall buildings can create a unique urban habitat known as a street canyon. These canyons trap traffic pollutants, limiting their dispersal into the atmospheric boundary layer that extends as high as 2,000 meters above the ground. A new study suggests that vegetation in street canyons may reduce air-pollutant concentrations much more than previously reported and suggests innovative plant...

Vanadium Removal from Fuel Oil and ‎Waste Water in Power Plant Using Humic ‎Acid Coated Magnetic Nanoparticles

   A method for treating fuel oil and waste water of power plant is suggested which is including vanadium elimination through contacting with humic acid coated magnetic nano-adsorbent. The nano-adsorbent was modified with humic acid (HA) as a compound having carboxyl, hydroxyl and amin functional groups. HA/Fe3O4 nanoparticles were prepared by a co-precipitation procedure and were character...

Classification of Abnormal Situations in a Waste Water Treatment Plant

The waste water treatment plants are very unstable and the waters to be treated are ill defined. The command of those processes needs to be done with advanced methods of control and supervision. They have to take into account the bad knowledge of the processes. The most important situations that imply problems for the plant are listed. Parameters for comparison between crisis and normal situati...

A Waste-To-Energy Power Plant with CO2 Sequestration

This paper assesses the technical and economic feasibility of a novel idea: Reducing the emission of carbon dioxide, the greenhouse gas contributing to global warming, by combusting solid wastes with industrial oxygen mixed with recirculated flue gas. The process gas, consisting mosdy of carbon dioxide, would be compressed and used in Enhanced Oil Recovery (EOR) projects. By using municipal and...
