Abstract
Phosphate is recovered from waste. Trialkali metal orthophosphate used to reduce, remove or retard bacterial contamination during raw meat slaughter including poultry, fish and shellfish and red meat evisceration is recovered from an aqueous waste and recycled as a food additive for animal feed. The waste water containing the phosphate can be collected and mixed with offal during processing of the offal or may be concentrated and blended with the offal as feed for animals or may be reacted with an alkaline earth metal salt and concentrated and used as a calcium and phosphate supplement for animal feed. Trisodium orthophosphate is reacted with calcium chloride and the resulting precipitate removed from the aqueous stream by filtration or centrifugation or other means for separation. The precipitate is then added to offal during processing for animal feed or dried sterilized and sold as an animal feed mineral supplement.
