The Thai Journal of Veterinary Medicine

The aim of this research was to preliminarily investigate the potential of earthworms to reduce clogging by introducing into the lab-scale wetland-like reactors receiving high strength wastewater, which were swine wastewater in Thailand, and domestic wastewater in Germany. The preliminary results indicated that every unit with earthworms had no sign of clogging regardless of the type of wastewater, whereas clogging was the case in the units without earthworms receiving swine wastewater. Both studies reflected similarity, which exhibited little treatment in every microcosm. It could be implied that earthworms could thrive within the wetland body due to the survival rate of …
