Remediation of acid mine drainage using natural zeolite
… and real AMD from Wheal Jane mine using natural zeolite. Laboratory experiments were performed to investigate the effectiveness of natural zeolite as a potential low cost material for the removal of these heavy metals from AMD. These include, equilibrium tests, batch kinetic studies, …

Removal of antibiotics from contaminated waters using natural zeolite
… ofloxacin (OFL), and enrofloxacin (ENR), on natural zeolite was investigated. The impact of pH and natural organic matter (NOM) on the sorption process was examined, and the maximum sorption capacity was calculated using the Langmuir-Freundlich sorption model. The results showed that at a …

The purification of industrial wastewater to remove heavy metals and investigation into the use of zeolite as a remediation tool
Zeolites are well-known aluminosilicate minerals that have been widely used as adsorbents in separation, purification processes and environmental pollution control. Zeolites are used in various industrial applications due to their high cation-exchange ability, molecular sieve and cataltic …

The impact of natural and synthetic zeolite when used in cementitious based systems
… engineering. Interestingly in the literature, zeolite minerals have the ability to absorb carbon dioxide and thus aid in reducing the concentration levels present in the atmosphere. Zeolites are very stable solids that are resistant to environmental conditions that challenge many other …

Treatment of natural rubber wastewater using oil palm empty fruit bunch, kaolin and zeolite as composite adsorbent
… study is to produce a composite adsorbent from natural zeolite, oil palm empty fruit bunch (EFB) and kaolin bound to chitosan to adsorb colour, chemical oxygen demand (COD) and ammoniacal nitrogen (NH3-N) from natural rubber wastewater. Batch and fixedbed adsorption techniques were used in this …

Hydrothermal synthesis and characterization of zeolite from Malaysia’s natural kaolin for adsorption of sodium ion (NA+) from seawater
Zeolite-A is widely known as aluminosilicate mineral that has been intensively used as an adsorbent in the adsorption process for desalination. Desalination is a technique to eliminate sodium ion and other minerals in the water. Because of the nature of seawater, which is very salty, the main …

Improving bioenergy recovery from municipal wastewater with a novel cloth-filter anaerobic membrane bioreactor
… ammonia recovery from permeate. Specifically, a natural zeolite (clinoptilolite) and two synthetic ion exchange resins (Purolite SSTC60 and Purolite C160) achieved an average effluent concentration of 1 mg/L TAN after 60, 118, and 107 bed volumes (BV), respectively. Alkaline regeneration of these …
