Every new and existing pressurized septic system should have a ClearFlow Pressure Filter

No. 1 Reason Gravity Filters Plug
April 2020 Onsite Installer Magazine published an article written by Sara Hager, Ph.D. engineer, researcher and instructor in the onsite wastewater treatment program in the water resources center at the University of Minnesota states "Large volumes of wastewater generated in a short period of time
can result in turbulence in the septic tank and reduced retention
time, which can lead to solids plugging the effluent screen."
CLEARFLOW is mounted on the outlet side of the pump
Nothing larger than 1/16” can pass through the filter into the force main.
The fluid head loss is 1.92 feet (.831 psi) at 50 GPM.
This amount of loss has shown to no effect on pump performance.
ClearFlow is not affected by heavy water usage
Every time the pump runs, the vibration creates 'shock waves' that have
a self-cleaning effect on the screen.
The screen is 42% open area
This means it will continue to function normally even when the screen
is partially plugged.
A completely plugged screen will NOT damage the system
If a ClearFlow filter does completely plug, the pump alarm will sound.
After the pump is turned off the screen can removed, cleaned,
and replaced without any solids entering the force main.
ClearFlow filter screen is 316L Stainless Steel
316 has proven to provide protection against corrosion in harsh environments.
The L stands for low carbon, which provides additional corrosion protection.
In a addition, the stainless steel contains an alloy called molybdenum.
Molybdenum increases strength & hardness and enhances resistance.
Heavy-duty housing
The housing that protects the filter is made of non-corrosive ABS plastic.
2-inch quick connect coupling
ClearFlow comes with a 2" quick-connect coupling that eliminates having
to purchase expensive unions and/or rubberized hose fittings. It also
makes servicing the pump quick & easy.
What happens when a gravity filter is pulled
Unless the septic tank is pumped before the filter is cleaned, when a partially plugged filter is pulled, solids will flow through the bottom of
the filter case into the pump chamber.
If a filter is completely plugged, the wastewater, fats, oils, grease and solids will rise above the top of the filter case. When the filter is pulled, everything floating about the case will flood through the top of the
case into the pump chamber, through the pump, into the force
main followed by the lateral pipes plugging orifices.
Lateral orifices range from 1/8" to 5/16" in diameter
Pressurized systems rely on even wastewater dispersal across the entire surface of drainfield. If one or more orifices become plugged, it results in uneven wastewater dispersal. Uneven dispersal
creates saturated, oxygen starved soil.
Saturated soil reduces septic system lifespan
-
Saturated soil causes oxygen starvation stopping the flow of air into the soil.
-
Saturated, oxygen starved ground creates anaerobic (do not need oxygen) bacteria.
-
Anaerobic bacteria produce a black, slimy,
jelly-like permeable bacterial substance
referred to as biomat, which stops
wastewater from flowing into soil.
4. As long as the ground remains wet, anaerobic bacteria will multiply in the oxygen-staved soil
increasing the area covered with biomat.
5. This effect will continue until the entire drainfield
is covered with biomat causing wastewater to
surface above the ground. The system has
failed and has to be replaced.
