Vermifiltration: Relying on nature's environmental engineers

摘要

Biological wastewater treatment systems have come a long way in the past 100 years, but one technology is pioneering a revolutionary new approach. Vermifiltration technology, which involves using worms to treat wastewater, has been designed around the lifecycle of worms. Typically, Eisenia fetida, commonly known as the tiger worm, is the key player in this process. Tiger worms are found throughout the world in and around compost heaps. As nature's environmental engineers, they feed on the natural waste, digesting up to their entire body weight every day.
