C-ION Arsenic Removal

Arsenic in groundwater is of natural origin and released from the sediment into the groundwater, depending on the anoxic conditions of the subsurface.

Arsenic pollution can also come from previous mining / chemical processes.

Arsenic in drinking water constitutes a serious health risk and may lead to chronic diseases like melanosis, spotty or diffuse hair loss, circulatory disorders, conjunctivitis, neuropathy, dizziness, depression, insomnia and headaches. The WHO (World Health Organization) has therefore adopted recommendation to limit arsenic in drinking water to 5 µg/l (ppb).

For the removal of arsenic SFC Umwelttechnik GmbH can offer the most innovative way of water treatment – a combination of ionOXess™ advanced oxidation with non-thermal plasma (oxidation of arsenide and organic compounds), iron coagulation (precipitation of arsenic) and C-MEM™ ultrafiltration membrane technology (complete separation of precipitations and bacteria/viruses > 0.2 µm). This process combination can remove arsenic from well water and treat it up to drinking water quality.

Advantages

much higher effluent quality compared to conventional treatment
small footprint
modularly expandable
easy installation and start-up
start-up/stops of operation possible
complete removal of suspended solids, bacteria and viruses (membrane barrier)
reduction of organic pollutants (NH₄, COD, pesticides, herbicides)
reduction of organic foulants
high oxidation potential
improved flocculation behavior
long lifetime of equipment, cheap and easy replacement
solar driven – very low power demand (NTP app. 30 W, aeration system app. 300 W)
no additional chemicals necessary, except iron salt
robust process, no fine mechanical parts

The process combination of the advanced oxidation process with non-thermal plasma ionOXess^TMand ultrafiltration C-MEM^TM can successfully eliminate arsenic contamination of 500 ppm to a degree of non-traceability.
