rejuWATER® is an ecosystem where someone's waste becomes other's food. Human waste in water gets bioconverted through microlife cultured in growRITE® STP soil. Bioconversion process breaks down the sewage to feed reed plants planted in the soil. Plants in return use soil nutrients and photosynthesis to feed dissolved oxygen (DO) to soil and water. All the elements in a rejuWATER module function symbiotically without any external power source.
