Likewise, the removal percentage of arsenic in solution during the electrocoagulation processes reaches a value of 99.99% while in the conventional coagulation processes have only been obtained a maximum of arsenic removal percentage of 80% when using iron salts and 70% when using aluminum salts.
Arsenic removal from water is recommended with a Reverse Osmosis System within your home or within a point-of-use water dispenser for clean drinking water. Reverse Osmosis is a process that forces water through a semi-permeable membrane under pressure that will leave contaminants behind and dispense more pure and healthy drinking water.

Arsenic compounds are carcinogenic to humans and are typically removed from contaminated water using various sorbents. The ionic composition plays a significant role in arsenate removal efficiency during the process of water remediation.
Abstract Arsenic contamination of drinking water is a serious health threat due to the highly toxic properties of arsenite. Water treatment by using ferrate ions is a promising new method as it has shown to effectively
Ferrate is a powerful oxidant and disinfectant that has been proposed for use in drinking water treatment in the US for more than a decade. In many ways, it …
Arsenic occurs in both inorganic and organic forms in water. Although various methods have been adopted to remove inorganic species of arsenic from drinking water, not much emphasis has been given to the removal of organic species of arsenic.
ARUBA (Arsenic Removal Using Bottom Ash) was developed at Lawrence Berkeley National Laboratory to remove arsenic from contaminated drinking water in South Asia in an efficient, affordable, and safe manner.
Ferrate is the most powerful, multipurpose, environmentally friendly water and wastewater purification chemicals known. In a single dose, super-charged iron(VI) replaces multiple treatment chemicals because it can simultaneously disinfect, oxidize, and coagulate to remove pathogens and contaminants from water.

Algae Removal from Lagoon Effluent Ferrate could be considered for treatment and removal of algae from facultative lagoon effluents. Concomitant with effluent treatment and disinfection, the Fe(III) by-product can promote coagulation of microscopic algae that can facilitate removal by settling or filtration.
The use of arsenic as a poison is widely documented. As a result, many people are alarmed when they hear that their drinking water, either from a public or private water system, may contain an amount of arsenic.
