Natural Coagulant Functionalized with Magnetic Nanoparticles Better Treated Dairy Wastewater Compared to Bioremediation

Several wastewater treatments are available nowadays, and the comparison among them is important when choosing the most suitable one. We investigated two emerging treatments for dairy wastewater, bioremediation, and coagulation/flocculation/sedimentation (C/F/S) using a natural coagulant functionali...

Description
Summary:Several wastewater treatments are available nowadays, and the comparison among them is important when choosing the most suitable one. We investigated two emerging treatments for dairy wastewater, bioremediation, and coagulation/flocculation/sedimentation (C/F/S) using a natural coagulant functionalized with magnetic nanoparticles, applied as a single step and also as a sequence. In the enzymatic treatment, lipases (500 U L −1 ) were used to hydrolyze fats at 96 h at 37 °C, while C/F/S evaluated different biocoagulant preparations, differing the salt and concentration used but with lower times (
