Reducing opex with primary & secondary sludge digestion.
At municipal wastewater treatment plants, sludge management represents a major operational challenge — both in terms of volume and cost. After primary and secondary treatment, the resulting sludge stream is bulky, difficult to handle, and costly to dispose of. Waterleau’s BIOTIM® Solids Reactor offers a smart and sustainable solution by converting this sludge into biogas through anaerobic digestion — while simultaneously achieving a drastic reduction in sludge volume.
This volume reduction not only lowers the environmental footprint but also translates into significant savings on transport and disposal costs, which can account for a large share of a municipality’s wastewater treatment budget. Combined with the generation of renewable energy in the form of methane-rich biogas, the BIOTIM® Solids Reactor turns a costly waste stream into a valuable resource — both environmentally and economically.
Energy from sludge in Fez, Marrakech and Kenitra
In large municipal wastewater treatment plants such as Fès, Marrakech, and Kénitra, Waterleau’s BIOTIM® anaerobic technology transforms organic pollution into renewable biogas, supplying up to 70% of the plant’s total energy demand. By replacing fossil fuels, it significantly reduces the carbon footprint and greenhouse gas emissions.
Across all wastewater treatment facilities, the cogeneration of heat and electricity from biogas fully complies with the Clean Development Mechanism (CDM) requirements under the Kyoto Protocol, allowing municipalities to benefit from sustainable energy production and certified emission reductions.
