Waterleau Group NV

Waterleau Group NV, headquartered in Belgium and part of the Machiels Group (founded 1941), is a global water technology company ranked among the top 10 in biological wastewater treatment by Global Water Intelligence. With approximately 600 water experts across all continents, Waterleau delivers proprietary wastewater treatment technologies including BIOTIM anaerobic systems (upflow anaerobic sludge blanket and expanded granular sludge bed reactors for high-load industrial wastewater producing recoverable biogas), LUCAS cyclic activated sludge technology for aerobic treatment, and Krofta dissolved air flotation (DAF) units—originally developed by Dr. Milos Krofta in 1972 and now offered in three configurations. The Krofta Supracell provides round shallow flotation for high FOG and solids loading (1.8–99 m³/h, up to 3× footprint reduction), the Multifloat offers ultra-compact rectangular DAF (1.5–136 m³/h, up to 7× footprint reduction), and the Sandfloat combines DAF with sand filtration for WWTP effluent upgrading (nominal 15 m³/h). The SmartLab digital platform provides process visualization, KPI dashboarding, and digital twin modeling for predictive plant management. Through Krofta DAF Rental, Waterleau offers containerized and skid-mounted mobile units including DAF systems, oil-water separators (10–50 m³/h), sludge dewatering equipment (screw presses and centrifuges), chemical dosing skids, buffer tanks, and fine screening equipment for capex-free short-term deployment. The WIFV financing vehicle enables off-balance-sheet project delivery. Waterleau serves pulp and paper, dairy, meat and protein processing, seed oil, soft drinks, brewery, sugar and distillery, textile, and municipal sectors.
