| Treatment process |
| As the earth's human and other animal
populations expanded and became more condensed, the quality
of water was threatened. The rivers and lakes were exposed
to pollutants, such as human waste, faster than it could
be cleaned through natural means. To protect the environment,
animal life, and human health and lifestyles, a system
was developed and refined to assist the natural process
to reduce the strain on the earth's natural resources.
