Abstract
A water purification solid material of relatively low cost whose handling is easy, produced from a natural raw material only; and a method of water purification with the use of the same. There is provided a water purification solid material for use in water purification using a microbe, characterized in that it is obtained by working only a natural raw material whose main component is a polysaccharide. Further, there is provided a method of water purification with the use of the same.
Claims3
A water-purifying solid material for microbially purifying water, consisting essentially of a processed non-synthetic material comprising:
- a polysaccharide as principal component;
- and
- nitrogen at a C/N ratio of 6 or more;
- wherein the water-purifying solid material is in a porous shape and has a solubility in water that is lower compared to a corresponding unprocessed non-synthetic material.
A water-purifying method, comprising placing a water-purifying solid material for microbially purifying water in a poor-oxygen region of water to be purified, the water-purifying solid material consisting essentially of a processed non-synthetic material comprising:
- a polysaccharide as principal component;
- and
- nitrogen at a C/N ratio of 6 or more;
- wherein the water purifying solid material has a solubility in water that is lower compared to a corresponding unprocessed non-synthetic material.
