ABSTRACT:
This invention relates to a method for treating soybean refinery wastewater. More particularly, this invention relates to a method for treating soybean refinery wastewater with an aqueous iron salt solution to produce purified water. An aqueous iron salt solution is admixed with soybean refinery wastewater, the resulting mixture is agitated and passed through at least one filter device to form a filtered effluent, and the pH of the filtered effluent is adjusted to a value below about 8 to form purified water.
