Separation of biocomponents from manure

A process for separating amino acids and peptides from raw and digested farm manure is disclosed. The raw manure may be recovered from sand bedding used in the cow stalls of some farms. The process involves the steps of precipitating out struvite and separating a stream rich in amino acids and pepti...

More Information
Summary:A process for separating amino acids and peptides from raw and digested farm manure is disclosed. The raw manure may be recovered from sand bedding used in the cow stalls of some farms. The process involves the steps of precipitating out struvite and separating a stream rich in amino acids and peptides from a mineral rich stream in a dissolved air floatation machine. Struvite precipitation is accomplished by the addition of polydicyandiamide and an acrylate based polymer, while the separation of the stream rich in fibers, amino acids and peptides from a mineral rich streams is accomplished by the addition of an acrylamide chloride copolymer.
