Existing Removal
Section III-B
PHOSPHORUS REHOVAL PROCESSES
111/8
The City of Fort Wayne Water Pollution Control Plant received in 1970
an average of 2650 pounds of phosphorus per day. Existing facilities
removed an average of 20 percent (without lime additions) prior to
discharging effluent to the Maumee River. In addition to effecting
this removal of total phosphorus, the treatment plant also converts
organic phosphorus and polyphosphate to orthophosphate, thereby producing
a form more amenable to chemical treatment.
Required Removal
The Indiana Strl~fpn Pollut:!.on Control Board has required that a mini.mum
of 80 percent phosphorus removal be achieved by the end of 1972. The
early deadline of this requirement \vill necessitate early construction
of facilities on an interim basis.
Final design of phosphorus removal facilities ~ill include provisions
to treat wastewater flm.rs 15-20 years in the future. It is difficult
to project the water quality criteria which will be in effect at that
time. !·lost likely, it will be more stringent.
Phosphorus content of the plant effluent will increase proportionally
to the wastewater flow if incoming phosphorus concentration and removal
efficiency are constant. Consequently, loadings to the receiving
stream from 60 HGD \.rould be tHice that at 30 HGD. Although reduction
in the amount of phosphorus received by the plant would
