If an
aerator diffuser for
water restoration
or
water management
lasts a lifetime and other aerators last 3 – 12 months,
we should consider the cost on a yearly basis. Also, if
the
lake, pond or wastewater aerator does not give good
water restoration or water management, its cost is
wasted. Many pond, wastewater or
lake aerator diffusers
cost less than CLEAN-FLO aerator diffusers. But these
other aerators are not always good water restoration or
water management.
You may pay $38.00 for a rubber membrane diffuser
aerator instead of $299.99 for a CLEAN-FLO
lake aerator diffuser, $229.99 for a
CLEAN-FLO
pond aerator
diffuser or $149.95 for a wastewater aerator diffuser.
The rubber diffuser is not weighted, so you may have to
spend $81.50 for a diffuser weight. The CLEAN-FLO
diffuser is self-sinking and has an average life of
about twenty years. We have seen rubber membranes last
three months. But let’s say they actually last for a
year. That means that if you replace the rubber diffuser
once a year, the cost over a 20-year period is $860. But
that diffuser was not weighted. A weighted diffusers
will cost $3,938 to replace twenty times, plus shipping
and labor to install it twenty times! But for every
CLEAN-FLO diffuser, you need four rubber diffusers for
lakes or eight rubber diffusers for wastewater. Thus, to
really compare the price of our diffusers with rubber
membranes, you will pay $15,754 plus shipping and labor
to get the same oxygen transfer.
Unfortunately, you cannot always have good water
restoration or water management with just eight rubber
membrane diffusers. These use only 0.8 CFM compared to
3.6 CFM for CLEAN-FLO’s
lake diffusers, 1.8 CFM
for CLEAN-FLO’s pond diffusers and 9 CFM for CLEAN-FLO’s
wastewater aerator diffusers. Good water restoration or
water management may require hundreds of membrane
diffusers.
One company provides 100 feet of air hose with their
8-diffuser package and NO cabinet (that’s an additional
large expense). The cabinet sits about 25 – 75 feet from
the shore to protect it from floods. That puts those
eight diffusers out 25 – 75 feet into the lake a few
feet apart. But the lake may be 3 - 300 acres. Such a
policy is not good water restoration or water
management.
Other companies may sell you four times the air hose
that we would use if they engineer the correct number of
diffusers for good water restoration or water
management. To get those four aerator diffusers out into
the
lake, it could cost you another $8,000.
Rubber diffusers sometimes tear and have to be replaced.
In spite of claims, they also may clog within 3 - 12
months. As a result, a worst problem than torn membranes
occurs that is not seen. Rubber membranes have about
2,000 holes in them. The CLEAN-FLO diffuser has over a
billion holes. The membranes begin to clog and swell as
soon as they are put in the water. As they swell, the
holes become larger. Now you have less bubbles coming
out of larger holes, with water restoration or water
management nothing like you expected or that CLEAN-FLO
attains.
