Description:
A detailed investigation was done to characterize the wastewater from a vegetable oil refinery. A calcium chloride chemical treatment was installed which resulted in a net decrease in waste load of 71 percent from .0135 lb BOD5 per pound oil processed to .0039 lb BOD5 per pound oil processed. A further reduction of 50 percent to .0019 lb BOD5 per pound oil processed was made by the addition of a clarifier to the treatment system. The net cost of treatment depends on the market value of the oil recovered and will range from $.032 per pound processed to a gain of $.063 per pound oil processed.
