One thought on “John Todd?

  1. John Todd is a biologist who developed an ecological approach to treating sewage. John argues that conventional sewage treatment is a process of transferring potential plant nutrients from homes and industries to rivers, lakes, and oceans where they overload these aquatic systems, By contrast, Todd’s system uses sunlight and a variety of living organisms to remove these nutrients from wastewater and then are put back on the land to support plant growth instead of being dumped into waterway and disrupting aquatic systems.
