“…10) but decreased in waste water from the screw press through which more solids were liberated into the waste water. The clarity of surimi wastes (0.35 to 25.57% T) were relatively lower than that of poultry chiller water (13 to 27% T, Chang and Sheldon, 1989a). However, UF permeates of all surimi waste waters were very clear with average percent transmittance 97.8.…”

Micro-and ultrafiltration were utilized for recovery of proteins and for water recycling from commercial surimi processing waste water. The proteins recovered by microfiltration showed highly functional properties and composition comparable with proteins in regular surimi. Surimi with a substitution (10%) of recovered proteins did not diminish in gel hardness, elasticity, color, or water retention. Aerobic plate count, chemical oxygen demand, protease activity, and turbidity in the surimi waste waters were reduced by ultrafiltration. Results indicated a potential for recovering proteins to extend yield and recycling water.

“…USDA's reuse standards were only partially met; bacterial reductions were adequate but light transmission values were not. Later work by Chang and Sheldon (1989b) demonstrated that USDA's requirements could be fully achieved after screening and diatomaceous earth filtration followed by ozonation with no adverse effect on carcass quality (Chang and Sheldon 1989a). Previous work by the authors documented increased effectiveness in reducing total aerobic plate counts (APC) from chiller water with an AOP (Diaz and others 2001).…”

Prior experiments using 250 mL samples of unscreened poultry overflow chiller water evaluated the beneficial bactericidal and oxidative effects of 4 different treatments (namely, O 2 /O 3 , O 2 /UV, O 2 /O 3 /UV, and O 2 as the control) for improving microbiological safety, turbidity, and water-use efficiency allowing its reconditioning for reuse. When excluding foam as in this present study, synergistic reductions . 1.5 log CFU/mL for aerobic plate counts (APC) were additionally achieved after 4 min for all O 3 /UV treatment combinations as compared to serially applied treatments of O 3 and UV acting separately. With foam present, 16-min O 3 /UV treatments were required to achieve similar results. We now report these additional benefits achieved by removing the foam formed by the advanced oxidation process of ultraviolet-photon enhanced ozonation. Furthermore, foam microbial and general physical content were analyzed to determine suitability as an additive in rendering-type processes. Treatment of the wastewater resulted in total plate counts between 2 to 4 Log CFU/mL in the foam after 8 min. Fat and protein constituted 89% of the solids collected (384 mg/L or 14% of the foam) with trace amounts of metal elements (for example, Ca, Na, K, Fe, Cu) present. Irradiating had negligible effect on foam characteristics yet decreased the amount of solids collected.
