Adsorption of Tetramethylammonium Hydroxide (TMAH) on Y-type Zeolite

Chang S., Lu C., National Chung Hsing University, TW

Y-type zeolite have high TMAH removal efficiency when pH>4 with solid-liquid ratio (S/L) of 2 g/L in 20 minutes. The correlation coefficients of Langmuir and Freundlich isotherm models are 0.973 and 0.997, respectively. The exponential [...]

New Nanostructures as novel electrodes in Capacitive deionization desalination Technology

Barakat N.A.M., Chonbuk National University, KR

Among the various introduced technologies for water desalination, capacitive deionization (CDI) is a very promising process. CDI (also called Electrosorption) attracted enormous attention as an energy-saving and environmentally friendly desalination technique, because it can be [...]

Nanofiltration: High Potential, Highly Misunderstood

Paulson D.J., Water Think Tank, LLC, US

A 40 year membrane technology developer defines the process of nanofiltration, using the too-common misconceptions of what NF is and how it employed to clarify definitional problems and propose solutions. Insight relating to the problems [...]

Titania Nanotubes for Separation Applications
