Protein Recovered from Industrial Waste Water as Feed for Chicks

Utilization of Fermented Flocculated Poultry Sludge as a Feed Constituent for Pigs

“…The disposal of sludge as a fertilizer is limited and becoming economically less attractive due to the introduction of new, restrictive environmental legislation. Over the years, several experiments have been performed to investigate the possibilities of the application of flocculated industrial waste water sludge for feed (Herstad and Hvidsten, 1973;Farstad et al, 1976;Grant, 1976;El Boushy et al, 1984;De Vries and Mulder, 1986).…”

Industrial whole animal blood. Characterization studies and quantitative protein removal by chemical coagulation

“…We have investigated the use of the nontoxic protein coagulants sodium polyphosphate, sodium lignosulfonate, lignin, and ferric chloride for effectiveness of protein removal from blood. These chemicals have been used by others for removal of protein from the wastewaters of cheese processors (Jones et al, 1972;Block and Bolling, 1955;Cerbulis, 1978;Hartman and Swanson, 1966;Riehert, 1973;Hidalgo et al, 1973), slaughter houses (Herstad and Hvidsten, 1973;Sanders, 1948;Hopwood and Rosen, 1972), and fish processors (Claggett and Wong, 1969;Spinelli and Koury, 1970). Our results demonstrate that chemical removal of blood protein, as a primary step in blood treatment, is feasible since several of the above discussed criteria are satisfied by such a process.…”

Precipitation of proteins from whey with bentonite and lignosulfonate

“…The process was used in 18 units in Western Europe. In a related study Herstad and Hvidsten (1973) reported that with 13% lignosulfonic acid in the diet, the weight gain of chicks was considerably reduced.
