The potential for disinfection of separated faecal matter by urea and by peracetic acid for hygienic nutrient recycling

Vinneras, B; Holmqvist, A; Bagge, E; Albihn, A; Jonsson, H

Abstract

PAA reduced all of the above indicator organisms within 12 h after application. For this faecal material, with a dry matter content of approximately 10%, an addition of 0.5-1% of PAA (active substance, corresponding to 3.3-6.7% of the Proxitane(R) 15 used) was required before no viable organisms were found in the material. However, this was not tested for the A. suum. No viable spore-forming bacteria or phages were detected. A high rate of bacteria regrowth occurred at 0.15% dosage and 5 days of treatment. PAA is an efficient alternative for disinfection of separated faeces if a rapid treatment is needed. (C) 2003 Elsevier Science Ltd. All rights reserved.
