What is it about?

The author of eBook is 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 able to be used more universally, testing together with plenty of other economic feasible natural or unconventional adsorption materials or even waste products and thus by certain portion contributing to future sustainability of our environment. Nearly all the examples contained in eBook are based on real experimental data.

Why is it important?

This review highlights the characteristic features of adsorption and ion exchange onto natural zeolite (clinoptilolite) for environmental cleanup processes, especially for water purification, zeolite´s past, present and future, with an emphasis on the recent developments in this field, particularly in the synthesis and manufacturing of the advanced cost-effective organic-inorganic (hybridized) zeolite-based adsorbents. An organic-inorganic composite adsorbent termed as a hybrid material too, may be defined hereto as a combination of a polymerous substance immobilized onto surface of the inorganic e.g. zeolite carrier to avail advantages of both zeolitic and polymerous constituents as well. Accordingly, hybridization can be used to modify organic or inorganic materials, and those hybrids should therefore be considered as the new generation of composites, that may encompass a wide variety of applications.

Perspectives

Furthermore, case studies about ammonium removal from specific drinking water with enhanced ammonium concentration by means of laboratory model is introduced in this review. The laboratory results were succeeded to field installation with the loading capacity of 900 liter per hour. Similar installation is introduced for ammonium removal of mixed tannery and municipal waste waters at Communal Water Reclamation Facility. However, one of the most preferential benefits of the advanced treatment process based on the selective ion exchange on clinoptilolite is the recovery of elutriants, i.e. the discussed technology is proposed with the mass closed loop operation. Nevertheless, the overall ion exchange - regenerant recovery system (IERRS) is by the proposed system design, as applied to a specific wastewater, evaluated on the base of the physical and economic aspects.
