Greensand Plus™

Greensand Plus™
Like its sister product manganese greensand, the substrate media
has a manganese dioxide coated surface that acts as a catalyst
in the oxidation-reduction reaction of iron and manganese. The
difference between Greensand Plus™ and Manganese Greensand
is in the substrate that forms the core of the media and the
method by which the manganese dioxide coating is attached
to that substrate. Greensand Plus™ has a silica sand core and
the coating is fused to it while Manganese Greensand has a
glauconite core and the coating is ionically bound to it.
The silica sand core of Greensand Plus™ allows it to better
withstand operating conditions in waters that are low in silica,
TDS and hardness. Thus, if you currently are using manganese
greensand and are feeding sodium aluminate, you will likely be
able to eliminate the aluminate feed by switching to Greensand
Plus™. Also, Greensand Plus™ can withstand higher operating
temperatures and higher differential pressures than can
manganese greensand. The higher differential pressure may
allow for a longer run length, but, if nothing else, allows for more
operational margin of error.
Along with the added benefits comes the fact that Greensand
Plus™ is an exact replacement for manganese greensand. It can
be used in CR and IR applications and requires no changes in
backwash rate or times or chemical feeds. Greensand Plus™ has
received the WQA Gold Seal Certification for compliance with
NSF/ANSI 61. It is available in easy-to-handle 1/2 cubic foot bags.
Greensand Plus™ is NOT shipped in a regenerated form; therefore
it is necessary, prior to use, to regenerate it contacting the bed
for a minimum of 4 hours.
