Arsenic Removal From Drinking Water Using Silica Based Catalytic Media
By Quantum Filtration
Arsenic is a common environmental contaminant found naturally in surface and groundwater resources used for potable supply. Typical values in the Waikato River in New Zealand are around 20 parts per billion (ppb) whereas the New Zealand drinking water standard is 10 ppb. It has become a major concern and challenge in water supply due to its toxicity and carcinogenic properties. Sources of arsenic contamination in surface and groundwater originate from both natural and anthropogenic sources.
