Zeolite in the Environment

AquaClean® – A zeolite-based aquarium filter medium, an innovative, natural product based on the unique properties of natural zeolite.

A pilot scheme in the municipality of Neapolis-Sykies to clean and ‘sanitise’ refuse collection lorries and the worksite, involving frequent disinfection and deodorisation using zeolite and aromatic liquids.

Publication regarding the approval of environmental conditions for the extraction of zeolite in Thrace by Lithoxos S.A., in the Palioklisi area of Petrota, Evros.

New developments regarding Greek zeolite and promising prospects for the coming year have been brought about by two new decisions from the Regional Council and the Directorate of Environment and Spatial Planning of Eastern Macedonia and Thrace.

In the most recently published study by the University of Patras, the effectiveness of natural zeolite in removing ammonium ions from synthetic wastewater and from secondary whey was investigated. Subsequently, the use of this zeolite as a fertiliser in wheat cultivation was investigated, given that zeolite can release bound nitrogen into the soil.

A study by the University of Patras, which investigated the effectiveness of natural zeolite in removing ammonium ions from synthetic wastewater and from whey.

The efficiency of natural zeolite to remove ammonium from artificial wastewater (ammonium aqueous solutions) and to treat second cheese whey was examined, aiming to recover nitrogen nutrients that can be used for further applications, such as slow-release fertilizers. Sorption experiments were performed using artificial wastewater and zeolite of different granulometries (i.e., 0.71–1.0, 1.8–2.0, 2.0–2.8, 2.8–4.0, and 4.0–5.0 mm). The granulometry of the zeolite had no significant effect on its ability to absorb ammonium. Nevertheless, smaller particles (0.71–1.0 mm) exhibited quicker NH4+-N adsorption rates of up to 93.0% in the first 10 min. Zeolite as a Potential Medium for Ammonium Recovery ... Read more

Zeolite and its potential uses in agriculture C. Sangeetha* and P. Baskar1, Department of Agronomy, Tamil Nadu Agricultural University, Coimbatore – 641 003, India. Received: 10-09-2015 Accepted: 25-02-2016 DOI:10.18805/ar.v0iof.9627 ABSTRACT In many parts of the world food security is being affected due to declining quality and/or quantity of the soil resource base and climate change. In this context, farming with zeolites has drawn attention. Zeolites are natural aluminosilicates present in rocks different part of the world. Use of zeolite has gained a momentum in the recent past owing to multitude of benefits accured from them. Zeolites are useful in agriculture because of their ... Read more

Soil contaminated with heavy metals and industrial waste is unsuitable for almost any type of crop. However, a new study has revealed that making a simple change could turn things around. Researchers at the Agricultural University of Tirana have discovered that simply adding natural zeolite can serve as an effective method for remediating soil contaminated with heavy soils. They observed significant variations in the changes depending on the proportion of zeolite in the soil, but overall the results appear to have been largely positive. The details of their research have recently been published in the Albanian Journal of Agricultural Sciences. ... Read more

zeolite gives life and in that sense it is a gift to people who are suffering because they are unaware of its existence. So it is your duty to make everyone aware of it, for it is a mission that helps the innocent; and if you encounter difficulties, then know that the value of your struggle for liberation will only grow. – Nikos Lygeros
