BIOCOS® - Maximum treatment performance with minimal resources

BIOCOS® technology, BIOlogical COmbined System, offers a smart, sustainable and space-saving solution for biological treatment of wastewater and is a lower-cost alternative to conventional activated sludge systems. Combining the power of activated sludge with the efficiency of granular sludge, this hydraulic system is distinguished by unique sludge selection and a cyclic process, fully controlled by air.

Integration with inDENSE® technology creates a compact, fast-settling biomass that provides excellent nitrogen, phosphorus (Bio-P) and carbon removal. The result? A robust system with high effluent quality, minimal maintenance requirements and up to 25% energy savings.

Why choose BIOCOS®?

• Compact and efficient: Small floor area, rectangular tanks, no pumps or mixers.
• Low energy costs: Smart air-controlled system (airlift), with no moving parts underwater.
• High effluent quality: Biological floc filtration via sludge blanket - perfect for water reuse.
• Improved Bio-P removal: By cyclone-controlled sludge selection in combination with inDENSE®.
• Low maintenance and reliable: No mechanical parts in aeration and sedimentation.
• Space-saving design: Ideal for sites with limited infrastructure.
• Proven technology: More than 150 installations worldwide, from 1,000 to 600,000 PE.
