Abstract

See full text

A two-step process for recovering useable solids from food processing wastewater and for significantly reducing the pollutants, chemical, bacterial, and viral load. The first step is the addition of pretreatment chemicals such as metal-based coagulant, pH adjuster, oxidant or a combination thereof. The second step is pumping the chemically pretreated wastewater into a foam fractionation system where a gas is introduced into the chemically treated wastewater to create a rising foam that captures and remove solid materials from the remaining wastewater effluent. The solids are recovered for additional post-processing and the effluent is discharged for post-processing or to existing bodies of water.
