is a relative newcomer to the growing list of contaminants.
It is generally a remnant of munitions and explosive manufacturing
as well as rocket fuel. Fortunately, there are ion
exchange resins that are highly selective and can
produce very high throughput capacities for perchlorate.
A530E (NSF listed) is one such resin and is widely
used throughout the world by municipalities and residential
users as well. Flow rates for municipal systems are generally
5 to 7.5 gpm/cu ft and residential systems are often designed
around one cu ft with lead/lag units of equal size.
ranging from 250,000 to 500,000 gallons per cu ft are
typical. Disposal of spent resin is generally considered
as hazardous waste.
can also supply 10 and 20 inch Aqualine™
Cartridges for under-counter systems or R/O polishing
applications for the removal of perchlorates.
