The self-purification power of water works well under the indigenous ecosystem functioning properly with a rich aquatic ecosystem pyramid. In polluted water with sludge accumulating at the bottom, water’s self-purification power decreases as a result of dominance by putrefactive microorganisms. This leads to decrease of nutrition necessary for ecosystem to function and keep their purification.
When applied to polluted and putrefactive water, EM helps revive the ecosystem by reducing sludge and foul odours. Nevertheless, the application of EM will not create crystal clear water as what can be done by chemical means. Depending on the water condition, the amount and frequency of EM’s application could vary.
