Hi Sergio,

The most effective and most cost effective method to treat used water from industrial operations is at the production area. By this I mean that it is best to minimise the organic loads being lost to drain and to minimise the volume of water used in the production area.

Then when the waste loads have been minimised the required treatment process can be designed. In the meat processing industry a good blood collection process is essential to minimise organic loads. In chicken processing dry processing of offal, rather than wet transport / pumping, etc., can greatly reduce organic loads.

Processing of value added products in meat plants, (such as gut recovery, hock recovery, etc can lead to very high water usage and in some cases very high losses of protein based materials, suspended solids, fats, etc).

It is therefore critical that the process commence with a critical review of the production areas to ensure that the efficiencies in the process are optimised.

Typically a beef or cow unit would be expected to use 1 m3 water and to generate 3.5 kg BOD per head to process, .... check how your facility compares to this "typical" target value.
