Nanofiltration: A technology for selective solute removal from fuels and solvents

Nanofiltration Technology for Toxic or Harmful Ions Removal from Groundwater: Characteristics and Economic Analysis

Nanofiltration (NF) membrane can efficiently remove the ions from groundwater, especially for high valence ions. Results show that the removal rate of fluoride was approximately 67% by the NF system, while for arsenic the removal rate was more than 93%. NF presented the well selective removal for fluoride. The quality of product water meets the national drinking water standards. Therefore, the ...

Nanofiltration as a Tertiary Treatment for Phosphate Removal from Wastewater

Gas Turbine Combustion and Ammonia Removal Technology of Gasified Fuels

From the viewpoints of securing a stable supply of energy and protecting our global environment in the future, the integrated gasification combined cycle (IGCC) power generation of various gasifying methods has been introduced in the world. Gasified fuels are chiefly characterized by the gasifying agents and the synthetic gas cleanup methods and can be divided into four types. The calorific val...

Potential of Nanofiltration for Phosphate Removal from Wastewater

Experimental investigations were conducted to evaluate the performance 01 n"nofillration fOr tertiary level phosphate removal from wastewater. A flat sheet type Oesal-5 thin 5lul nanofi)tration membrane in a plate and frame module, was IJsed.
