AWS operating principle
The AQUA Wetland System (AWS)
consists of three cells, each lined with
an impermeable synthetic liner. Each
cell contains a sand/grave medium and
cattail plants (typha sp.). Wastewater
is applied to the top of the first cell in
series via buried ‘summer’ and ‘winter’
distribution manifolds. Water from the
bottom of cell # 1 is collected and then
applied to cell # 2 in the same
manner. Likewise, water from cell # 2
is applied to the top of cell # 3. The
treated water is then discharged from
the system. Winter time operation is
accomplished via buried ‘winter’ dosing
manifolds and in summer via ‘summer’
dosing manifolds located on the cell

Treatment process
Physical, chemical, and biological processes combine
within the AWS to remove contaminants from
wastewater. Treatment occurs as the wastewater
passes through the AWS sand medium and the plant
rhizosphere. A thin aerobic film around each root hair
is aerobic due to the leakage of oxygen from the
rhizomes, roots, and rootlets of the cattail plants.
Decomposition of organic matter is facilitated by
aerobic and anaerobic micro-organisms present.
Microbial nitrification and subsequent denitrification
releases nitrogen as gas to the atmosphere.
Phosphorus is co-precipitated with iron, aluminum, and
calcium compounds located in the root-bed medium.
Suspended solids are filtered out by the sand medium
of the AWS and subsequently decomposed. Harmful
bacteria and viruses are reduced by filtration and
adsorption by biological films on the sand media.
