Kurian et al. [31] and Viitasaari et al. [19] demonstrated that O&G, proteins, carbohydrates,
nutrients and suspended solids are in high concentration in food industry wastewaters . Thus,the
sludge generated from flotation was rich in these pollutants.From Table2, it reveals that the mean
calorific value of sludge generated from flotation was higher than that of the animal feeds and food
wastes because the sludge from flotation gavea mean value of 6690cal/g while tha tof the highest
of them was only 5257 cal/g [33:Guavawaste].Therefore , thesludge from flotation was apotential
candidate to be reused as ananimal feed with high energy value. Table2 also shows that the mean
total phosphorus level (0.11%) of the sludgefrom flotation approached that of the food wastes [32:
Bread and noodle waste —0.17 and 0.11%].The bread and noodle waste were usually collected by
farmers from restaurants and food processors to feed their swine and poultry.Therefore ,the sludge
generated from flotation may beutilized as a feed for this farming.The table also reveals that the
mean protein content level(8.26%)of the sludge generated from flotation approached thatof the
animal feeds (Native hay and Whea tstraw : 9.0 and 3.9%) [35] and the guava waste[33:9.61%] but
lower than that of most of the food wastes.Lira et al. [33] claimed that guava waste was used to feed
poultry (i.e.Broiler and laying hen).Therefore ,the slud gegenerated from flotation may be recycled as
a feedfor the poultry farming.
