Outstanding Cost Reduction in Waste Water Treatment

Outstanding Cost Reduction in Waste Water Treatment

Belize Sugar Industries Ltd. (BSI) has been producing sugar in Orange Walk Town, Belize since 1967.
Since they process approximately 1.3 million tons of sugarcane per year, they have been searching for a sustainable solution to manage their wastewater. Further, they wanted to reduce cost since they were applying an aeration system that consumed vast amounts of electricity.

Location: Belize


EM holdings tanks Activated EM・1 (AEM) is prepared on-site to be used within the wastewater coming from the sugar processing plant. They activate EM・1 and apply it once a week. They had problems with bad odours caused by hydrogen sulfide and ammonia gases within the wastewater treatment ponds as well as pollution problems that kill fish and aquatic life in nearby rivers. They also faced problems in control COD and BOD in effluents.


After applying EM Technology for one year here are their successful results: 1. Complete odour control 2. Marked reduction in housefly population 3. Complete elimination of air pumps and hence elimination of maintenance cost 4. Significant reduction in labour cost associated with pond management 5. Increase the avian population around the treatment pond area 6. Reduce time in treatment labour operations 7. COD, BOD, sludge and other physical and chemical parameter improved in wastewater effluents
