decrease the loading, control legislation for this purpose is uncertain.
The above discussion illustrates the need for higher removal efficiencies
than 80 percent. It has been determined that 90 percent removal would
be feasible. It would produce similar loadings to the Maumee River
at future flows as present flmvs \vill produce at 80 per-cent
removal. Present technology has the capability for 90
percent phosphorus removal.
Use of Existing Facilities
The activated sludge process, as operated at the Water Pollution Control
Plant, can be altered and/or supplemented to provide phosphorus removal.
Although some removal operations can be constructed as a separate
treatment process, several schemes incorporate use of the primary
settling, aeration and secondary settling tanks. Usually, these
schemes actually increase the removal efficiency of the affected process.
~ludge disposal is an important design factor when incorporating
phosphorus removal. Several methods produce a considerable increase
in the amount of organic sludge. Sludges of a chemical nature instead
of organic are also generated. Disposal of these sludges may require
disposal techniques different from those presently practiced.
The existing digesters can treat sludges which do not exhibit characteristics
detrimental to the anaerobic process. It is anticipated
that the added volume of these sludges will be basically inorganic in
nature and will not seriously affect the normal capacity of the digesters.
