Effective microorganism (EM) is a mixture of beneficial microorganisms that is widely used in agriculture. The microorganisms in EM also show impressive performance in water and waste management by breaking down the organic matters and suppressing the growth of pathogenic microorganisms. This attribute makes EM an ideal solution to treat pig farm wastewater which generally has high organic content. In this study, the performance of EM in treating pig farm wastewater was evaluated from 25 participating local pig farms in Kuala Langat, Selangor, Malaysia. A treatment of 1 litre EM and one mudball was added to each cubic metre of lagoon in the farms. The initial and final Biological Oxygen Demand (BOD) values were measured where the results showed that 23 farms obtained BOD values within the allowable limit. The highest BOD reduction was recorded at 97.32 %. The findings suggested that the application of EM is helpful in treating pig farm wastewater in terms of BOD reduction. Using EM as part of the wastewater treatment routine not only help the farmers to comply with the rules, but also promotes green practices in the livestock farm as the waste can be managed in an effective and sustainable manner.

Abstract

Effective microorganism (EM) is a mixture of beneficial microorganisms that is widely used in agriculture. The microorganisms in EM also show impressive performance in water and waste management by breaking down the organic matters and suppressing the growth of pathogenic microorganisms. This attribute makes EM an ideal solution to treat pig farm wastewater which generally has high organic content. In this study, the performance of EM in treating pig farm wastewater was evaluated from 25 participating local pig farms in Kuala Langat, Selangor, Malaysia. A treatment of 1 litre EM and one mudball was added to each cubic metre of lagoon in the farms. The initial and final Biological Oxygen Demand (BOD) values were measured where the results showed that 23 farms obtained BOD values within the allowable limit. The highest BOD reduction was recorded at 97.32 %. The findings suggested that the application of EM is helpful in treating pig farm wastewater in terms of BOD reduction. Using EM as part of the wastewater treatment routine not only help the farmers to comply with the rules, but also promotes green practices in the livestock farm as the waste can be managed in an effective and sustainable manner.
