Summary

A study was conducted to determine the general composition of equilibrated poultry chiller water (near maximum solids content) from a commercial operation, the chlorine consumption by its components, and the chlorine dosage necessary to achieve its disinfection. The equilibrated chiller water contained solids, which consisted of lipids, ash, and total nitrogen. Residual chlorine and survival of aerobic bacteria were determined in chiller water dosed with chlorine levels ranging from 0 to 400 ppm. Initially, the added chlorine was rapidly consumed by the components of chiller water. However, the consumption rate quickly decreased to 1/1,000 of the initial rate after about 50 min. The change of residual chlorine with time was found to fit mathematically to a two-term exponential equation. Relation between chlorine dosages, bacteria counts and time, are analysed.
