The sugar industry generates wastewater, condensate water, and byproducts such as biomass (bagasse), molasses, and pressmud. Major sources of wastewater include the mill house, boiling section, floor washings, machinery leakages, cooling towers, and evaporator CIP waste. Condensate water primarily comes from evaporation processes.

Biomass (bagasse) is used as fuel in boilers to generate steam and power for the industry. Molasses is processed in distilleries to extract ethanol/alcohol, while pressmud is utilized as fertilizer for farmers.

Challenges in wastewater treatment include managing COD/BOD levels and other pollutants, as well as reusing condensate water, which may contain organic traces, and disposing of pressmud.

We propose wastewater treatment solutions that involve biological anaerobic processes followed by a single-stage aerobic system with polishing units to PCB standards. For evaporator condensate water, we recommend aerobic treatment followed by polishing units to recycle treated condensate for cooling tower makeup or imbibition.

Additionally, we offer pressmud-based biogas plants utilizing cutting-edge Thöni Paddle Agitator CSTR technology to process pressmud, a high-solid substrate, for optimal biogas generation. This includes an H₂S scrubber, membrane-based CO₂ scrubber, and CBG handling system. The Thöni Paddle Agitator and feeding system enhance biogas yield while reducing water and electricity consumption. We also provide screw presses for dewatering treated pressmud slurry, producing solid and liquid organic manure. The pressmud-to-CBG system generates continuous revenue for customers.
