Superior efficiency BIOPAQ^® ICX now independently proven

190+ full-scale references in all major industries confirm that the BIOPAQ^® ICX has already been accepted by the market. After all, it offers excellent biomass retention / COD removal and works efficiently at a high volumetric loading rate like the extensively researched and broadly applied BIOPAQ^® IC system. Which actually increases efficiency and effective volume up to 25% compared to UASB systems ² .

But the difference with BIOPAQ^® IC is that the BIOPAQ^® ICX design is much more compact. The BIOPAQ^® ICX anaerobic bioreactor fits existing systems of any supplier, which simplifies construction, shortens the startup time, and decreases costs compared with BIOPAQ^® IC ³ . But also makes the sustainable internal circulation technology suited for small wastewater treatment plants ³ . But now, the performance and superiority of BIOPAQ^® ICX is also proven scientifically.

Up till now, there was no reproducible scientific study with replicable results that confirms our commercial claims. But now, you don’t have to take our word for it anymore. We stumbled upon the publication of an independent scientific study by Tuan Minh Truong Dang - employed by the Research Institute of Environmental Toxin and Emerging Contaminants - and Ha Manh Bui - employed by the Faculty of Environment of Saigon University. They delivered scientific proof that BIOPAQ^® ICX is a stable, reliable system and excels in treating high-strength paper mill wastewater.

Read on to discover their findings or go to the scientific article.

Anaerobic bioreactor BIOPAQ^® ICX effectively treats complex industrial wastewaters, such as high-strength paper mill wastewater. In this case study, sCOD >11,800 mg/L was tested and effectively treated.

BIOPAQ^® ICX is stable and works efficiently up to VLR 26.8 kg/m3/day, achieving process efficiency exceeding 81%. This Volumetric Loading Rate was set as maximum threshold for this facility based on an earlier study ⁴ .

Comparing installations for pulp and paper wastewater treatment, they found that BIOPAQ^® ICX is suited for a bigger VLR range than IC, EGSB & UASB technologies - with a better sCOD removal efficiency as well: 70-89%.

Want to upgrade your existing anaerobic reactor with or build a new biological water treatment system?

BIOPAQ^® ICX combines the excellent properties of the BIOPAQ^® IC reactor with a high flexibility with regard to tank design. The unique 2-stage biomass retention system of the BIOPAQ^® ICX ensures excellent biomass retention, enabling high volumetric loading rates.

The compact system of the BIOPAQ^® ICX is implementable in existing tanks, making it particularly suitable for upgrading existing anaerobic reactors that are underperforming or not suited for higher-strength influents.
