Contents:
This review discusses treatment processes within stabilisation ponds generally, and then examines dairy pond systems in the light of this conceptual understanding. To define the treatment standards necessary for dairy shed waste discharges, the quality of current dairy shed stabilisation pond effluent is evaluated from a receiving water perspective. The "priority pollutants" in dairy pond effluent, ranked according to the required dilution factors to meet receiving water guidelines, are : #nutrients# promoting nuisance growths, #faecal indicator bacteria# that measure potential risk to human and livestock health, #ammoniacal nitrogen# which can be toxic to stream life and also contributes significantly to oxygen depletion, and #suspended solids# for their effects on stream life and aesthetic quality.
