Applying microorganisms directly to the settled sludge layer in municipal lagoons and ornamental ponds is a cost effective alternative to dredging. Facultative bacteria that are active in low oxygen or anaerobic environments will permeate throughout the sludge layer.
The bacteria are capable of degrading residual organic material contained in the sludge layer, which minimizes the amount of sludge as well as the settled volume. This reduces dredging costs and frequency, improves performance, controls odors, and minimizes nutrient flux.
