"One mud ball is needed for every one square metre and the size of Lake 4 is 1,100 square meters. The mud ball works on a delayed release basis, as the water dissolves the mud, slowly releasing the EM solution into the water." C. K. Chung, chief executive officer of MicroGreen Group of companies.
"EM solution is a liquid containing many microorganisms, namely lactic acid bacteria, yeast and phototrophic bacteria. It works by providing a boost to the microflora, which forms the base of the ecosystem. The water is then purified through the food chain of plankton, small animals and fish" Senior technical officer for EM Research Organisation (EMRO), Yasushi Nishibuchi
