Wastewater Treatment

Whole-Stillage Treatment and Combined Heat and Power for Cassava-Based Ethanol Production

This project adopts a cleaner production process. Drawing on our experience in the integrated treatment of wastewater (stillage) from cassava-based ethanol production, it uses two-stage anaerobic treatment of whole stillage. The anaerobic treatment system combines a mature, highly efficient thermophilic…

Heat Integration of Molasses-Based Ethanol Distillation and Stillage Concentration

Stillage from the distillation section is pre-concentrated using process waste heat, increasing its organic solids content from approximately 15% to approximately 30%. A live-steam-heated final concentration unit then raises the organic solids content from approximately 30% to 65–70%. The concentrate…
