Chicken Abattoir Effluent Case Study

and case studies page



A small successful poultry abattoir on the south coast of Kwa Zulu-Natal is being treated by FBF Organics' Abattoir Bio Activator. They slaughter and pack eight thousand chickens a day for super market shelves. Their process uses 17 litres of water per bird which flows into a newly constructed properly designed system of ponds.

FBF Organics was called in to this Poultry Abattoir, a couple of months after the pond system had been commissioned because of a "serious problem in the primary pond", according to the owner. Upon arrival we were hit by the stench as we saw a group of unfortunate labourers "trawling" the surface water attempting to haul off an unhappy and obviously heavy gruel of fat, feathers and other pieces in some kind of makeshift net.

The feather screen had to be immediately sorted out and so too the pond.
A couple of days later FBF Organics returned to install a small bio-activator at Riversmead that fed the stressed primary pond, still thick with odour and grease but fewer feathers, with the Abattoir Bio Activator pumping at fifty litres an hour.

Two weeks later they visited the pond again and the odour had all but gone and there were signs that the surface grease was breaking up. Six weeks later the grease scum on the surface had retracted by 70% and there were already signs of bubbling from enhanced microbial activity in the sludge layer below. Anaerobic-Pond-ab

Subsequent visits to the ponds were very pleasing. As the sludge settled in, large eruptions of gas bubbled up from it as the bacteria in consumption mode, 'converted' solids from the abattoir into nutrition and in so doing released gas. Bacteria operate from existing surface area in the water. They don't move around like fish within water looking for nutrients, which is why each eruption is important. It breaks up the sludge and enlarges the surface area of the sludge for bacterial activity within the sludge and by implication the populations of bacteria colonizing the freshly exposed surfaces.

8000 Chickens X 17 litres of water = 136,000 litres per day of pink, fatty water into the primary pond. This equals to 952,000 litres a week and 3,808,000 litres of water a month, that have to be returned to a natural stream, within acceptable legislated parameters.

Another component of the cleansing of this pond is the large number of carnivorous birds waiting for that piece of something red, that I mentioned earlier, coming down the pipe way into the pond.
FBF Organics is eco friendly, it works and it is cost effective. All wastewater needs it.
