Sugarcane Industry Wastewaters Treatment
Abstract The sugarcane industry, and particularly one that produces distilled potable products besides sugar (sucrose), generates wastewater with a high content of organic and inorganic compounds that are difficult and costly to remove. Particularly those from ethanol production, known as vinasses (...
