Carrousel

Reliable and efficient treatment of industrial and domestic wastewater

Carrousel is a proven, cost-effective, reliable and highly efficient method for the biological treatment of municipal and industrial wastewater. Its clear advantage is the continuous biological process of BOD removal and simultaneous nitrification and de-nitrification in a single reactor with only limited equipment required. Over 1,200 systems have already been successfully implemented world-wide, with treatment capacities ranging from as little as a thousand to as high as ten million population equivalent

Crystalactor

Resource Recovery

The patented, zero-waste, Crystalactor water treatment technology can be used to treat water flows of all sizes, by removing certain target components, such as a large number of heavy metals and other inorganic compounds.

The benefits to Crystalactor:

• Reduced chemical consumption and therefore, costs
• Optimised process performance, leading to savings in operational costs for back-washing of downstream carry-over filters
• Process robustness, which leads to significantly reduced operator attendance, less maintenance and higher capacity availability
• Easy operation and reduction in ‘spend hours’ of operators

Kaumera

Resource Recovery

Kaumera is a new bio-based resource which is extracted from aerobic granular sludge originated from the Nereda wastewater treatment process.

Applications for Kaumera:

• It provides an excellent coating material for slow-release fertilizers and paper
• It is a bio-stimulant (agriculture)
• It can be used as a binding agent to help pelletise powder-like materials as struvite
• It is a fire retardant
• It can be used as a curing agent for concrete
• It can be combined with other raw materials into bio-nanocomposite materials.

Ephyra

Sludge digestion to optimise anaerobic digester performance

Innovative sludge digestion technology for optimising anaerobic digester performance

Operational benefits of Ephyra:

• Expansion of sludge processing capacity by 50-80% without increasing reactor volume
• Enhanced (20% to 30%) biogas production, due to a higher breakdown of sludge
• Up to 20% improvement of the total energy consumption of the WWTP
• Smaller reactors required, due to a higher sludge concentration
