Abstract The prolonged start-up time and low total nitrogen removal of anammox hinder its full-scale application. Herein, application nano-zerovalent iron strength magnetic field in sole combination to abbreviate the period long-term process stability was carried out. reactor’s with only (R3) 34 days, saving 43.3% compared control. increase efficiency over control 43.7% during period. However, ...

Water treatment using nano-materials can have a significant impact due to its surface properties. Coagulation techniques were studied by 3 mL/L of 0.5% different coagulants (polyacrylamide, poly aluminum chloride (PAC), ferric chloride, sulfate, and nanocellulose). Results indicated that the turbidity removal efficiency 91.6%, 93.04%, 95.2%, 95.4%, 99.4%, respectively. Treatment water samples c...

leachate treatment from municipal landfills has been always a major anxiety in waste management due to its high level of various contaminations. in this paper the effect of nanosized zero valent iron particles (nzvi) in fenton process for the treatment of high cod strength landfill leachate was scrutinized. the results corroborated this procedure was fast and efficient. in fact, about 87% of in...

background contamination of water resources with nitrate is a serious environmental problem in many regions of the world. in addition, this problem has been observed in some regions of iran. as nitrate is threatening for human health and environment, it must be decreased to standard levels in drinking water. objectives the purpose of this research was to model the nitrate removal from water by ...

The in situ synthesis of air-stable zero-valent iron nanoparticles (NZVI) embedded in cellulose fibers leads to the assembly of highly reactive magnetic filter papers. These engineered materials display a wide range of applications in the treatment of wastewater and drinking water, including chromium removal, phenol degradation, environmental bioremediation, and catalysis.

Nowdays, iron nanoparticles due to their unique characteristics are used in all of sciences and technology. These nano particles due to their electrical, magnetic, optical and catalytic properties and having high area and activity that is promped by their small size and most importantly many scientists from the entire world are interested in their low cost production. In this project we used me...
