Abstract
This paper presents an analysis of operating data from two types of subsurface
flow wetland treatment systems operating in the temperate climate of North
Alabama. Specifically data sets from five traditional gravity flow and a
sequential batch reactor design treatment systems were used to quantify expected
BOD, ammonia, nitrate and turbidity values. Since nitrogen compounds have
been difficult to remove in the past, a statistical analysis was performed on the
ammonia and nitrate removal efficiencies. A calculation of sample means
revealed that the expected value of effluent ammonia a
