Glendon Biofilter®
Description:
A Glendon Biofilter® is made up of a buried basin – usually a concrete tank –
filled with sand and gravel. After sewage passes through a septic tank, it ente
pump tank where it is pumped to the Biofilter®. After moving into the bottom of
the basin, it flows up through the layers of media. It then moves over the rim o
the basin and down into the sand-covered area surrounding the unit where it
absorbs into the original soil.
Function:
The function of the Glendon Biofilter® is to clean the wastewater to a high le
before passing it into the underlying original soil. The basin provides mechan
filtration and anaerobic breakdown of wastes. The mound sand provides an
oxygen-rich surface area for treatment. Microbes consume
th
e water as it flows through to the underlying original soil for dispersal.
M
aintenance:
• Glendon Biofilters® must be checked yearly by a
• Check basins for solids build up when other tanks are checked. Pump as
needed.
• Check surface of mounds for soggy spots or breakouts.
• Clear mounds of large vegetation & ensure ports are accessible.
• Ensure the mound shapes are maintained. Plant grass, et
from sloughing. DO NOT FILL around/between mounds
• See Sections 1 & 2 for more information on protecting your drainfield.
