Food Industry Wash Water Sample Clauses

Food Industry Wash Water. A waste effluent was prepared to simulate wastewater from a soy milk operation with a composition of approximately 3% soy solids and 2.5% sodium hydroxide. In the initial boil-down test, the fluid became very foamy after 50% of the water boiled off. The viscosity rose to syrup level and a foul odor occurred as the liquid boiled down to a solids content of approximately 6.5%. Testing in the table-top distiller indicated similar results. An initial 1000 ml was placed in the table-top distiller. After 500 ml of the water was boiled-off, the water in the distiller became very foamy. The conductivity reading of the distillate was 240 uS/cm. The next 100 ml boiled-off was tan in color with conductivity greater than 5,000 uS/cm. When the distillation chamber was opened, the foaming was sufficient to carry liquid over into the distillate. The caustic soda-soy mixture was also found highly corrosive to the copper. Consequently, no further testing is planned with this fluid. However, recognizing the wide variability of waste effluent streams in the food industry, this industry remains a viable opportunity for the Ovation distiller.
