Bokashi composting for home kitchen waste at the EcoDepot/EcoDrop. In India, effective microorganisms have been used in an attempt to treat some sewage-polluted lakes in Bangalore in 2015. After the Bangkok floods of 2011 effective microorganisms were used in an attempt to treat polluted water. Scientific methods to investigate applications of wastewater additives have come to the conclusion that long-term beneficial effects are not proven. Pit additives used for improving the performance of sanitation systems do not work, because "the quantity of bacteria introduced to the pit by dosing additives is insignificant compared to the number already present in the faecal sludge. Similarly, while some additives operate on the logic of adding more nutrients to the sludge to feed bacteria and encourage their growth, faecal sludge is already rich in nutrients." With regards to this situation, effective microorganisms is used for treating polluted waterways caused by faecal sludge, usually mixed with bokashi mudballs, to disinfect and consume sludge and disinfect water.
