TLDR
The results showed that modified (heat treated) zeolite achieved 26-30% higher removal of heavy metals compared to natural untreatedZeolite, and the integrated system produced high quality fresh water while concentrating sulfuric acid and valuable heavy metals (Cu, Zn and Ni).About:

Current status and future prospects of membrane separation processes for value recovery from wastewater
TL;DR: In this paper , the potentialities of different membrane processes in value recovery are presented, and the details are discussed to drive home that membrane processes can be useful to achieve the objectives of value recovery, in a cost effective manner through process intensification, as they are more compact and individual streams can be treated and value used seamlessly.

Selective copper extraction by multi-modified mesoporous silica material, SBA-15.
TL;DR: High regeneration and reuse capacity of Mn-SBA-15-NH2 were well established by its capacity to maintain 90% adsorption capacity in a multiple advertisersorption-desorption cycle.

Environmentally sustainable acid mine drainage remediation: Use of natural alkaline material
TL;DR: In this paper, the effect of three alkaline materials: marl, sandstone and calcareous crust on acid mine drainage neutralization and metal precipitation was evaluated, and a batch test was designed, where a 5/10 alkaline material(g)/AMD(mL) ratio was used.
Journal ArticleDOI
The Application of Submerged Modules for Membrane Distillation.
TL;DR: It was found that much higher values of the permeate flux were obtained when the membranes were immersed in the feed with the distillate flowing inside the capillary membranes, which led to higher efficiency of capillary modules without an external housing.

Study of the selection mechanism of heavy metal (Pb2+, Cu2+, Ni2+, and Cd2+) adsorption on clinoptilolite.
TL;DR: The study was carried out on the sorption of heavy metals under static conditions from single- and multicomponent aqueous solutions by raw and pretreated clinoptilolite and results fit well to the Langmuir and the Freundlich models.
Journal ArticleDOI
Adsorption of heavy metals from acid mine drainage by natural zeolite
TL;DR: In this article, the adsorption behavior of natural zeolite (clinoptilolite) has been studied in order to determine its applicability in treating acid mine drainage.
Journal ArticleDOI
Purification of metal electroplating waste waters using zeolites
TL;DR: This mineral showed the same high sorption capacity values when used in the purification of metal electroplating waste waters, appearing, therefore, as most suitable to perform metal waste water purification processes.
Journal ArticleDOI
Removal of Heavy Metals from Mine Waters by Natural Zeolites
TL;DR: The immobilization of the metals during pH increase and the subsequent remobilization caused by re-acidification can be well described by a geochemical equilibrium speciation model that accounts for metal complexation at hydrous ferric oxides, for ion exchange on the zeolite surfaces, as well as for dissolution and precipitation processes.

Removal of lead, copper, nickel, cobalt, and zinc from water by a cancrinite-type zeolite synthesized from fly ash
Wei Qiu,Ying Zheng +1 more
TL;DR: In this paper, a cancrinite-type zeolite (ZFA) was synthesized from Class C fly ash via the molten-salt method and the maximum exchange level (MEL) was found that the uptake of heavy metals on ZFA was subjected to an ion exchange mechanism.
