Hith proper pH control and a relatively warm ambient air temperature,
the ammonia s tripping process is· capab Ie of removing over 90 percent
of the ammonia in the waste.
Spray Irrigation
The spray irrigation process provides one step final disposal method
for a secondary effluent since it consists of simply spraying the
'vas tewater over the soil. A 'veIl drained soil is an absolute requi remen
t and the possibility of ground water contamination mus t be carefully
evaluated. The process is used only for relatively small volumes of
'vastmvater due to the large land areas required. Problems have also
been encountered \vith build-up of chlorides and sulfates in the soil
resulting in deterioration of the land.
CHENICAL PROCESSES
Chemical Coagulation and Precipitation
The various methods for precipitation and coagulation of phosphorus
compounds, and the associated additional removal of suspended solids,
are discussed in Section 1II-B of this Report.
pH Control.
pH control is seldom necessary as an end in itself when treating a
municipal wastelvater. Instead, it is used to condition the vlaste
stream for optimum performance of other processes or to provide an
acceptable pH value for discharge. Adjustment of pH may be accomplished
by addition of acid, base, or certain salt solutions. Another common
method is to inject a soluble ionizing gas into the 'vaste stream as in
the use of carbon dioxide (t.,1hich forms a 'veak acid in 'vater) in the recarbonation
process.
