Preface

The author of the eBook is a former project leader responsible for clinoptilolite-rich tuff utilization in water treatment and water purification processes, currently preparing some new advanced or innovated postmodified zeolite adsorbents that can be used more universally, testing together with plenty of other economic feasible natural or unconventional adsorption materials or even waste products and thus by contributing to future sustainability of our environment. Nearly all the examples contained in the eBook are based on real experimental data.

In the author´s memory such zeolite experts names like B.W. Mercer, L.L. Ames, F.A. Mumpton, R. Svetich, all from USA, A. Dyer from Great Britain or L. Liberti from Italy, will remain forever some of whom the author visited or met personally and was instantly impressed by their intense human approach, e.g. by Prof. Mumpton during the zeolite conference Slovzeo in High Tatra (former Czechoslovakia, 1984) and Zacatecas (Mexico, 2003), by Prof. Dyer at the International Conference on Occurrence, Properties and Utilization of Natural Zeolites in Budapest (Hungary, 1985) and also in University of Salford (Great Britain 2002), and by Prof. Liberti at the University of Bari (Italy, 1995).

The author was pleased by the warm welcome of the responsible zeolite chemist at TTSA and Waste water facility at Tahoe (California), (Dr. R. Svetich, in January 1995), facility which was the best and first in the world applying clinoptilolite-rich tuff for water treatment.

The author also admires the pioneering works of B.W. Mercer and L.L. Ames with their coworkers, published in 1975 under US Water Pollution Control Federation (WPCF) Journal, which was accidentally accessible at the author´s former employer Water Research Institute in Bratislava and offered great inspirations to zeolite researchers of that time.
