Waterleau is a global leader in anaerobic wastewater treatment, offering a versatile range of BIOTIM® anaerobic reactors designed to handle wastewater and biosolids with varying organic loads and dry matter content.

In anaerobic treatment, organic pollutants are transformed into biogas—a mixture of methane (CH4) and carbon dioxide (CO2). This biogas is recovered and utilized as a sustainable energy source for electricity generation and heating. Additionally, anaerobic treatment significantly reduces sludge generation compared to aerobic processes, providing both environmental and operational benefits.

Starting up a new anaerobic reactor requires a specialized sludge feedstock. Waterleau accelerates this process with high-quality granular anaerobic mesophilic sludge, rich in methanogenic activity. With over 400 anaerobic reactors in our network, we ensure a reliable supply of anaerobic granular sludge for various needs, including plant startups, capacity expansions, reactor maintenance, and addressing system incidents.

To guarantee optimal performance, Waterleau’s laboratory evaluates the methanogenic activity, granule size, and sedimentation velocity of the sludge before shipment. We also support clients in valorizing surplus anaerobic biomass, maximizing resource efficiency.
