The use of submerged bed technology in biological wastewater treatment has a number of advantages, such as higher biomass concentration in the bioreactor, best resistance to contamination points and subsequent better sludge settling. Faced with mobile beds submerged, there is the advantage of bed extraction with a simple lifting and cleaning.

It has great flexibility in the treatment process and provides a high degree of debugging, resisting with optimum performance possible hydraulic or pollutant load points.
