Sludge Treatment / Anaerobic Digestion

Anaerobic digestion is the process for the reduction of sludge without the use of air or elemental oxygen. In anaerobic digestion, organic pollutants are converted by anaerobic micro-organisms to a gaseous product (including methane gas) that has the potential for reuse. It is a very low energy process, that produces a fraction of the waste sludge generated through aerobic biological processes. It is particularly recommended for treating wastewater which is high in soluble BOD and/or COD.

Digestion Mixing

Anaerobic Digestion is highly dependent upon effective sludge mixing. When tank contents are inadequately mixed, stratification occurs.

Membrane Gasholder

fixed steel digester covers and membrane gas holders are key components of an anaeraobic digestion solution, when recovery of biogas is leveraged.

Sludge Pre-Treatment

Several technologies and innovations have made their entry recently, to favor sludge reduction, including Ovivo® SonolyzerTM Ultrasound Sludge Disintegrator.

Steel Covers

Anaerobic digestion is a biological treatment occuring in the absence of air or elemental oxygen. Organic pollutants are converted by micro-organisms into gas.
