1. UV-Assisted Microreactor for Waste water-treatment Figure 1 Photodegradation photographs of the molasses The waste water from sugar industries and distilleries, which contains melanoidin. It causes soil, air and water pollution. Photodegradation of Water Introduction Schematic Diagram (Proposed UV-Microreactor) Figure 3 System with multiple tubes coated with catalyst, electric heater and ultraviolet light source for photodegradation Figure 2 System with catalyst coated tube for photodegradation, heater and UV source The process is temperature dependent. The chemical oxygen demand (COD), biological oxygen demand (BOD) and total dissolved solids (TDS) of the waste from sugarcane factories, on passing through this reactor and photodegrading, decrease significantly, thereby reducing the pollution.
