An analysis of cascade-aerated facultative waste stabilisation ponds in the United Kingdom
journal contribution
posted on 2013-07-05, 13:24 authored by Bernhard Rinnhofer, Michael SmithThis paper examines the performance of cascade-aerated facultative ponds in a
waste stabilisation pond (WSP) installation in the United Kingdom. The pond
system is privately owned and treats wastewater from a conference centre with
a population equivalent between 20 and 40. A snapshot analysis investigates
the removal efficiency of BOD, COD, SS, FC and nutrients. Further, the oxygen
supply through ‘flow form’ cascades is examined, and the DO concentrations,
surface loads and retention times are discussed. The results show a very high
removal of BOD, COD and SS; and nutrient removal is satisfactory. An unusual
finding is that the FC removal efficiency is almost two log units better than for a
common maturation pond. This is possibly attributable to the high cascade
flow, where wastewater is exposed to the damaging effects of sunlight (photooxidation).
