Paques maintains a vast network of evaluated & approved biocatalyst suppliers and logistics across the globe. We have access to major quantities of high-quality biocatalyst, mostly originating from our own high-performing Paques bioreactors. This enables us to meet demand and quickly satisfy any request, large or small, with efficient transportation of healthy & highly-active biocatalyst.

New anaerobic plants start with the addition of methanogenic active granular biocatalyst, also called anaerobic granular sludge, which is harvested from our network of vetted and approved source bioreactors.

Well-engineered and operated existing reactors often have a net biocatalyst growth. However, there are conditions that can lead to loss or degeneration of anaerobic granular sludge, or malfunctions that can lead to decreased biomass content. Under these circumstances, topping up, re-seeding or even complete renewal of the biocatalyst may be advised. Paques’ supply service can help you to solve these situations.

Paques’ trade in anaerobic granular sludge has been optimized during our 40+years of experience. That’s why more and more companies with anaerobic WWTPs contact Paques first when they are in need of anaerobic granular sludge.

The function and efficacy of the powerful THIOPAQ^® system is both based on the reactor design and the biological process. For a balanced and smooth start-up or restart of the reactor, Paques offers THIOPAQ^® Start-up Biocatalyst. This thick, yellow liquid is a suspension of highly-active bacterial strains and stabilizing additives. The Thiobacilli, which oxidize hydrogen sulfide to biological sulfur granules, are selected from stable, high-performing THIOPAQ^®® systems. Paques supplies THIOPAQ^® biocatalyst worldwide in IBC containers, ISO tanks, or tanker trucks.

Paques is the exclusive supplier of superior ANAMMOX^® biocatalyst.Our global network guarantees general availability and swift delivery times.

The key to a well functioning ANAMMOX^® process is a healthy, granulated, AMX-rich biocatalyst. Paques’ reactors and operational conditions have been developed fully-focused on obtaining this ideal, compact microbial community. Our reactors enable us to provide customers with highly-active and well-settling ANAMMOX^® granules.

Paques supplies ANAMMOX^® biocatalyst in IBC containers, ISO tanks, or tanker trucks. Through preparation, the biocatalyst can survive multi-day shipment when needed.

Highly specialized wastewater analyses are highly recommended or even necessary if you wish to qualify your reactor biocatalyst, assess process additives or additional waste water streams, or if you suspect contaminants negatively influence your treatment results.

Paques laboratories, generally used for internal R&D activities, are also available for such analyses. The following test are a great way to generate detailed information about your biological system and the health of its treatment process:

• Microscopic characterisation
• Methanogenic activity tests
• Sulfidogenic activity tests
• De-ammonification activity tests
• Aerobic activity tests
• Toxicity assays
• Biodegradability assays
• (Heavy) metals contents analyses
• Surfactants, flocculants or fat detection
• Biogas composition analyses
• Long-term laboratory bench tests

Our dedicated laboratory staff has been trained to handle your samples quickly and with accuracy. They provide you with the lab results, additional information and practical advice about biological wastewater treatment.
