ReCip for municipal and on-site wastewater treatment
- Leslie L. Behrends, PhD (Tennessee Valley Authority,
Muscle Shoals, Alabama)
ABSTRACT: The Tennessee Valley Authority (TVA), has
developed and patented a novel technology for aerating
the root zone and rock substrates of subsurface flow
constructed wetlands. The technology, referred to as
recurrent reciprocation, was retrofitted to a municipal
subsurface-flow wetland treatment system in November
1995. Prior to the retrofit, the municipal wastewater
treatment system was failing with respect to several
NPDES water quality parameters including fecal coliform
bacteria counts. Within six months of retrofitting the
reciprocating system, water quality and fecal bacteria
populations were significantly improved and have continued
to improve for the past four years. Data will be presented
comparing water quality data prior to and after installation
of the recurrent reciprocating technology.
