In Cargills Quality Dairies(Pvt) Ltd., the second largest milk factory in Sri Lanka, they have great result with treating waste water from the factory, using EM.

The factory discharges 450,000L of waste water per day. At the inlet, Activated EM･1 is added every week to start treating the waste water.

The waste water is separated into fluid and solid matter (fat). The fat is transferred to a fat dome where they also throw EM in twice a week.

Before the introduction of EM, the fat dome could not process separated fat well. The water used to remain white even after going through the fat dome, and its odor was terrible. With EM application, the dome performs its role perfectly to treat the fat with fermentation and the processed water became gray, instead of white color. (*The color of the water is usually darker when the fat is processed well.)
