The major objectives of this study were to evaluate the capacity of two natural New Zealand zeolites (clinoptilolite and mordenite) to remove NH 4 + from a range of wastewaters under both batch and flowthrough conditions. Effects of two zeolite particle size ranges (0.25-0.50 mm and 2.0-2.83 mm) on NH 4 + removal performance were also ...

It indeed only requires testing on undiluted samples of natural waters or wastewaters discharged into the aquatic environment, except for wastewaters that demonstrate more than 50% effect. The scoring system ranks the waters or wastewaters in 5 classes of increasing hazard/toxicity, with calculation of a weight factor for the …

This paper presents the experimental results on the use of rice husk in the removal of lead (II) from the aqueous solution. In this study, rice husk is used in four different forms, namely, natural un-activated form (RH), rice husk ash acquired after carbonizing rice husk without pretreatment (RHA), rice husk pretreated with phosphoric acid (PRH) and acetic acid …

The CRMs' extraction in a selective way can be achieved using highly selective recovery processes, such as chelating sorbents. This study focuses on extracting Trace Elements (TEs) from solar saltworks brines, including boron, cobalt, gallium and germanium, using commercial N-methylglucamine sorbents (S108, CRB03, CRB05). …

The aim of this study is to investigate ammonium removal from wastewaters by using natural zeolite supplied from Dogantepe (Amasya) region in Turkey. Section snippets Preparation and measurements of zeolite samples. Zeolite samples used in this study were taken from Dogantepe (Amasya), Turkey.

The scheme of the acid treatment (A -natural zeolite; B -H-zeolite) and the structure of clinoptilolite (C) 2.2. Reagents, chemicals, and instrumentation The certified analytical standards of ...

This study considered the potential of a natural Australian zeolite, clinoptilolite, to remove ammonium from water. Ammonium-exchange capacity and rates of adsorption are critical to the assessment of the feasibility of the zeolite for application to continuous wastewater treatment. A laboratory study was undertaken, using pure …

A laboratory batch study was conducted by using a lab-grade solution of Pb 2+ and Cu 2+ made from lab-grade PbCl2 and CuCl2 compounds (Sigma-Aldrich Co., St. Louis, MO, USA).

The nanochitosan was extracted from shrimp wastes and modified by Schiff base ligand and graphene oxide. Nanochitosan characterization was carried out by Fourier-transform infrared spectroscopy, scanning electron microscope, transmission electron microscopy, energy-dispersive X-ray spectroscopy, atomic force microscopy, and …

Natural clays were used as adsorbent to remove ciprofloxacin from aqueous solutions by adsorption. The textural, structural, and morphological properties were examined, finding low-moderate specific surface area values (9.9–50.1 m 2 g −1) and a structure coincident with the smectite phase.Adsorption kinetic studies revealed that clay …

The natural-based innovative f- was highly efficient for simultaneous P and N removal from wastewaters at a wide range of pH values (5–9). Compared with …

Phosphorus from wastewaters and sediment flux to surface water represents a major source of lake eutrophication.Active filtration and in situ capping (which refers to placement of a covering or cap over an in-situ deposit of contaminated sediment) are widely used as a means to immobilize phosphorus from wastewaters and sediment, to mitigate …

Proof of concept testing. The effectiveness of PAA hydrogels in sorbing NH 4 –N from wastewater was initially investigated using raw wastewater. Figure 1 shows that the NH 4 –N concentration ...

Natural treatments are appropriate for the treatment of domestic wastewaters of small or isolated areas because they require large land areas to be settled. Nonetheless, their advantages are greater than their disadvantages because natural wastewater treatment systems have a low impact on the landscape, use minimal energy and little to no ...

Abstract Ammoniacal nitrogen (ammonia and ammonium) in agricultural wastewaters can promote eutrophication of receiving waters and be potentially toxic to fish and other aquatic life. Zeolites, which are hydrated aluminum‐silicate minerals, have an affinity for ammonium ions (NH4 +) and are, therefore, potentially useful in removing this contaminant from …

Natural or synthetic resins are usually used for the removal of metals from the wastewater. Some of the examples of the ion exchange process using different types of resins are given in Table S5. However, the process comes with certain disadvantages, such as the process is not economic, as the cost of the resins used is very high and sensitive ...
