OSMORIA™ Geoclean® is meticulously developed to meet diverse stormwater management needs. It offers tailored solutions for various levels of hydrocarbon pollution, with three variants - Origin, Crystal, and Pure - allowing engineers to select the appropriate filtration level based on the expected pollution load.
Designed for both open-air and buried infiltration structures, OSMORIA Geoclean can be installed in ditches, retention basins, infiltration trenches, and more. Optimizing the fixation and biodegradation of hydrocarbons (PAHs) over the long term ensures that 100% of the stormwater passing through is treated, allowing clean water to infiltrate the soil.
Key advantages
The OSMORIA Geoclean range - Origin, Crystal, and Pure - offers increasing levels of hydrocarbon fixation and biodegradation to match the specific.
Options designed for large widths (3 m and 6 m).
Exceptional performance: it has demonstrated a more than 99.9% retention rate for hydrocarbons, with a residual concentration as low as 0.7 mg/.
Applications beyond stormwater management
OSMORIA Geoclean also provides an effective solution for protecting soils in refueling and parking areas for construction machinery. It ensures hydrocarbons are fixed within its oleophilic filaments while still allowing water to flow freely into the soil, preventing the spread of pollutants beyond the treated area.
An alternative to confined soil management
In cases of contaminated land, OSMORIA Geoclean offers a cost-effective alternative by wrapping the polluted soils. This prevents hydrocarbons from leaching out during water infiltration, allowing for in-situ reuse of the soils and significant cost savings.
A range of solutions for every project
The OSMORIA Geoclean range - Origin, Crystal, and Pure - offers increasing levels of hydrocarbon fixation and biodegradation to match the specific needs of your project. With options designed for large widths (3m and 6m) and durability exceeding 100 years (according to NF EN ISO 13438 standards), OSMORIA Geoclean is built to last.
Recognized environmental performance
Tested and validated by renowned institutions like CEREMA and LEESU, OSMORIA Geoclean ensures high rates of biodegradation. From the first month, it achieves over 2.2 g HC/m²/week in biodegradation, leading to an annual rate of 120 ml HC/m²/year. Compared to natural soil, OSMORIA improves the retention and degradation of hydrocarbons, making it capable of managing even higher levels of pollution.
