“…These wastes can be discharged to a receptor body if they comply with the regulations; on the contrary, they must be submitted to treatments such as chemical precipitation and coagulation-sedimentation-filtration with the generation of solid wastes (muds or sludges). In the case of semiliquid wastes, they must be submitted to thickening and dewatering processes [ 32 ]. Though, different effective, reliable, and sustainable methods of As waste disposal have been developed and proposed, recent emphasis has been given on stabilization/solidification (S/S) technologies, which are currently used to treat industrial wastes containing As [ 33 ].…”

“…The regulatory agencies around the globe such as World Health Organization (WHO) [4], US Environmental Protection Agency (USEPA) [5], Health Canada [6], and European Union (EU) [7] have set maximum limits on arsenic in drinking water to 0.01 mg/L to ensure the safe consumption of arsenic-contaminated drinking water to protect people from diseases. People of different parts of Bangladesh, West Bengal [8] and some other parts of India [9], Cambodia [10], Inner Mongolia of of semiliquid wastes, they must be submitted to thickening and dewatering processes [32].

Arsenic (As) removal is of major significance because inorganic arsenic is highly toxic to all life forms, is a confirmed carcinogen, and is of significant environmental concern. As contamination in drinking water alone threatens more than 150 million people all over the world. Therefore, several conventional methods such as oxidation, coagulation, adsorption, etc., have been implemented for As removal, but due to their cost-maintenance limitations; there is a drive for advanced, low cost nanofiltration membrane-based technology. Thus, in order to address the increasing demand of fresh and drinking water, this review focuses on advanced nanofiltration (NF) strategy for As removal to safeguard water security. The review concentrates on different types of NF membranes, membrane fabrication processes, and their mechanism and efficiency of performance for removing As from contaminated water. The article provides an overview of the current status of polymer-, polymer composite-, and polymer nanocomposite-based NF membranes, to assess the status of nanomaterial-facilitated NF membranes and to incite progress in this area. Finally, future perspectives and future trends are highlighted.

“…Other studies point to constructed wetlands as appropriate treatments for arsenic removal. Litter et al (2019) conducted a review study on technologies for removal of this contaminant in groundwater in Argentina and indicated that in addition to the most common technologies used in that country, the construction of wetlands is also promising.…”

Arsenic-contaminated waters represent environmental and public health problems. The use of plants has emerged as a viable, cost-effective, and low environmental impact alternative to treat these polluted waters. This review presents studies published in the year 2019 on phytoremediation covering the effects observed on plants, trends in plant species selection and treatment of arsenic-rich biomass. Studies on application of this technology are exposed through constructed (treatment) wetlands, and a brief contextualization on the impacts of arsenic contamination was also performed.

“…Figure 1 shows the countries where natural As in water has been detected. Argentina.-A compilation of studies conducted in Argentina related to the presence of As in water has been reported in various publications [7][8][9][10][11][12]; the Chaco-Pampean plain (about 1 million km 2 ) is the largest area affected by groundwater As contamination in LA. Arsenic release involves the influx from dissolution of volcanic glass, adsorption of As on Fe and Al mineral phases in relatively low pH zones, and high mobility of As in high pH zones [9].…”

An overview of arsenic (As) presence in waters in Latin America (LA) is presented. Aspects on As occurrence, effects of As on human health, regulations regarding the maximum allowable concentration of As in drinking water, analytical techniques for As determination, and conventional/emerging technologies for As removal developed in LA are mentioned. Arsenic presence has been identified in many LA countries in a range of concentrations, originated from various sources; however, its origin is mainly natural. Main analytical techniques available in LA laboratories are described. Pathologies derived from the chronic consumption of As, the metabolism of As in the human body and the effects of the different As chemical forms are detailed. A list of conventional and emerging technologies for As removal in LA waters for human consumption, for large, medium and small populations, rural and periurban, is reported. Conclusions and recommendations to face the problem are included.
