AdEdge Technologies’ AD33 media
is the industry standard for arsenic
reduction that reduces up to 99%
of total arsenic, including both
arsenic (III) and arsenic (V). It is
also effective in reducing other heavy metals such as lead, cadmium,
chromium, antimony and molybdenum. This revolutionary new ironbased granular adsorption media has 4 to 10 times the capacity of
many adsorption medias. AdEdge’s product is specifically designed
for commercial and residential POE and small systems to meet the
new EPA arsenic standard of 10 ppb. Developed in the mid-nineties,
this ferric oxide-based product has been successfully used in largescale drinking water applications since 1999. The AD33 media is
discardable when spent and requires no chemicals or regeneration.
It has become the premier product of choice for POE whole-house
drinking water treatment systems for reliable, cost-effective, proven
reduction of arsenic.

Technical Specifications
AD33 provides cost effective centralized arsenic treatment with a
typical life of 2-3+years before replacement. The media exhibits
high operating capacity across a wide range of pH, influent arsenic
concentrations and flow rates. It is simple to apply in standard POE
vessels with typical flow rates of 2-10 gallons per minute. Once the
media is exhausted, AD33 can be discarded as a non-hazardous
waste (specific state requirements should be consulted). Media is
easy to handle and can be stored and shipped dry.
Certified to
NSF/ANSI 61
Expected life bed volumes....................................... 15,000 to 125,000
Spent media disposal..........................................Non-hazardous waste
