“…Low ammonium nitrogen content and high nitrate nitrogen content in the purified sewage in the investigated soil bed proves very good conditions of the nitrification process what implies that nitrifying bacteria are well immobilized on the natural clinoptilolite. This phenomenon is described in the literature [15,16]. The pH reaction increased by 2.5% on average in the purified wastewater (for both investigated soil beds).…”

“…It is used to absorb odors in poultry and pig farms, i.e., to remove nitrogen oxides [12]. Investigations are also carried out on the application of the clinoptilolite in veterinary medicine [13] and as a remover of trace metal ions [14], nitrogen compounds [15], phosphates [16] and radioactive elements [17] from water; trials have been undertaken on application of the clinoptilolite to purify municipal and refinery wastewater.…”

Model investigations of wastewater purification were carried out in a medium sand bed with an assisting natural clinoptilolite layer 0.10 or 0.25 m thick. The effectiveness of wastewater purification related to basic qualitative parameters was in accordance with the Polish standards on sewage disposal into grounds and surface water. Medium sand soil bed with the assisting natural clinoptilolite layer 0.25 m thick showed on average the removal efficiency regarding TSS higher by 3.3%, total nitrogen by 29.3%, total phosphorus by 25.9%, reduction efficiency regarding BOD5 by 1.1% and COD by 15.9% than that with the thinner clinoptilolite layer. The investigations confirmed that natural clinoptilolite with the granulation 1-5 mm can be used to enhance the removal of nitrogen and phosphorus compounds from wastewater with the application of infiltration drainage. However, very good effect of the TSS removal from the wastewater in the investigated soil beds can lead to their fast clogging under the infiltration drainage. Septic tanks should be designed in such a way that they retain as much TSS as possible, e.g., multi-chamber tanks instead of one-chamber ones.

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 NH 4 + -N adsorption rates of up to 93.0% in the first 10 min. Maximum ammonium removal efficiency by the zeolite was achieved at ammonium concentrations ranging from 10 to 80 mg/L. Kinetic experiments revealed that chemisorption is the mechanism behind the adsorption process of ammonium on zeolite, while the Freundlich isotherm model fitted the experimental data well. Column sorption experiments under batch operating mode were performed using artificial wastewater and second cheese whey. Column experiments with artificial wastewater showed high NH 4 + -N removal rates (over 96% in the first 120 min) for all granulometries and initial NH 4 + -N concentrations tested (200 and 5000 mg/L). Column experiments with second cheese whey revealed that natural zeolite can remove significant organic loads (up to 40%, 14.53 mg COD/g of zeolite) and NH 4 + -N (about 99%). For PO 4 3− -P, the zeolite appeared to saturate after day 1 of the experiments at a removal capacity of 0.15 mg P/g of zeolite. Desorption experiments with water resulted in low NH 4 + -N and PO 4 3− -P desorption rates indicating that the zeolite could be used as a substrate for slow nitrogen release in soils.

“…A zeólita clinoptilolita apresenta elevada afinidade pelo cátion NH4 + e diversos estudos na literatura têm avaliado a sua aplicação na remoção de amônia, principalmente no tratamento de águas contaminadas (BEEBE et al, 2013), como trocador de íons e como adsorvente. Assim, devido a elevada seletividade por amônia, grande disponibilidade deste tipo de zeólita na natureza e baixo custo do material, a zeólita clinoptilolita tornou-se um adsorvente muito competitivo em comparação aos outros materiais utilizados para a remoção de amônia em efluentes por processos de adsorção e troca iônica (KARADAG et al,2008).…”
