  • Micro-organisms at work in a sewage farm
  • Duration: 00:49
  • Micro-organisms are helpful in the disposal of human waste. Our waste material in the form of sewage is treated at a sewage farm. The clean and filtered water is finally sprayed over rocks and any microscopic bits of sewage still remaining are eaten by a variety of micro-organisms. There is a beautiful and fascinating sequence of magnified micro-organisms. The clean water is then fit to be released into a river.
