BioKube Wastewater Treatment Systems are an important way to conserve one of the most precious resources that sustains all life – water. This is an especially important consideration in the semi-arid island environment of Aruba and other Caribbean islands. Rotech is proud to represent the BioKube brand of self-contained wastewater treatment systems for individual homes, commercial buildings and even entire neighborhoods and residential developments. After wastewater is treated by the patented Danish technology of a BioKube system, the water can be re-used for a variety of purposes, including irrigation, maintenance, dust prevention, cooling towers, toilet flushing, fountains and ponds, and more.
