Abstract
The present invention provides a soil ball for water purification with increased hardness and microbial population. According to the soil ball for water purification with increased hardness and microbial population of the present invention, the addition of a hardener increases the hardness such that the degradation of the soil ball in water is delayed, and the addition of a buffer solution prevents an increase in pH to increase the microbial population, thus improving the effect of water purification.
