A Athos™ Athos™ is a sludge hydrothermal oxidation (HTO) process that turns organic sludge with low dry matter into an essentially solid mineral. Sludge treatment B Biobulk™ CSTR The Biobulk™ CSTR technology (Completely Stirred Tank Reactor) is a robust and proven process which treats industrial effluents with significantly high amounts of suspended solids. It is the anaerobic equivalent to the conventional activated sludge digestion system. Anaerobic Wastewater Treatment H Hydrotech™ Disc Filters Hydrotech™ mechanical and self-cleaning Disc filters provide reliable suspended solids removal for municipal effluent polishing and industrial water reuse.
