Water purification and lava/lava-basalt dust!
By Marc Daelemans
More than 60 years ago prominent German scientists, under the guidance of Dr. K. Seidel, rediscovered, by observing nature, the self-cleansing process of natural rivers, streams, and waterways.
Botanical sewage purification, a natural process, is an outgrowth from classical land treatment of wastewater. Today, this classical method of application to land has been updated and serves as an ideal, natural way to purify human, animal and industrial sewage. It also has the potential to clean rainwater, reservoirs, and groundwater. The system consists of shallow basins connected by pipes. The purification is accomplished through a symbiotic relationship of substrate (lava and lavadust) and anaerobic and aerobic bacteria and certain aquatic plants. The process is subdivided into two steps: Pre-purification and Main - Purification.
