EM mudball- alternative method for domestic wastewater from Mawar College, UiTM Shah Alam: article

Domestic wastewater is one of our main water sources for daily life. But, most domestic waste water are smelly, dirty, blackish in color and full with trash and are not well managed[⁵]. This led to pollution that causes bad effect to our health and an increased in other living microorganism in the drain such as E-coli, Fecal Streptococcae and Salmonella[²]. To overcome this issue, the absorption method by organic waste could be used which is EM mudball[⁶]. Effective microorganism (EM) consist a multicultural of anaerobic and aerobic beneficial microorganisms is presently gaining popularity due to its environmentally friendly nature[⁵]. Method that used to carry out this study is through the laboratory experimental for all consider parameters. The result obtained shows that EM mudball are capable to drastic reduce the COD, turbidity, SS, and color and also pH value start from third week. For COD it reduced to 168mg/L. While for turbidity, it reduced to 28.7 NTU. For suspended solid it reduced to 4.3mg/L, color reduced to 617.7unit PTCO and for pH the value decrease to 8.25 where closer to reach neutral level. But for DO, the values are keeping increasing till 6.3mg/L. Results show that EM mudball has potential to improve the effectiveness of treatment of domestic wastes.
