Waterleau is a recognized leader in anaerobic wastewater treatment. Our range of BIOTIM® anaerobic reactors are tailored to treat wastewater and biosolids with different organic loads and dry matter contents.

During anaerobic treatment, organic pollutants in water are converted into a blend of methane (CH4) and carbon dioxide (CO2), forming biogas. The biogas is recovered and utilized as an energy source for electricity generation and/ or heating . An additional benefit of this process is a significant reduction in sludge growth , compared to aerobic wastewater treatment.

Initiating a new anaerobic reactor necessitates a specific type of sludge feedstock. Anaerobic Sludge accelerates the reactor’s start-up by introducing concentrated granular anaerobic mesophilic sludge with high methanogenic activity. T With a network of over 400 anaerobic reactors, Waterleau can promptly supply anaerobic granular sludge . Moreover, we also assist in valorizing your excess anaerobic biomass. The methanogenic activity, the granule diameter and the sedimentation velocity of granular sludge are assessed in our Waterleau lab before shipment.
