Product
Targeted microbial solution that reduces PAH contamination in sewage sludge by up to 20x, enabling safe land application and regulatory compliance.
The Challenge
Polycyclic aromatic hydrocarbons (PAHs) are persistent organic pollutants found in sewage sludge. They're carcinogenic, environmentally toxic, and heavily regulated.
When PAH levels exceed regulatory thresholds, sludge cannot be applied to agricultural land — forcing expensive disposal through incineration or landfilling. This creates massive costs for municipalities and water treatment facilities.
Traditional chemical treatments are expensive, create secondary contamination, and don't achieve the reduction levels needed for land application compliance.
Municipalities spend millions annually on sludge disposal when PAH levels prevent land application. Incineration and landfilling create additional environmental burden and represent pure cost with no recovery value.
The Solution
ORP's sewage treatment solution uses a custom-cultured consortium of up to 15 specific microorganisms selected to target PAH compounds in sewage sludge.
These microorganisms break down PAH molecules through natural biological processes, achieving contamination reductions of up to 20x — bringing sludge well within regulatory compliance for safe land application.
The treatment is 100% organic. No chemicals are introduced. The byproducts are non-toxic. And the treated sludge becomes a valuable resource rather than an expensive waste product.
Documented reduction in PAH contamination levels, bringing sludge within compliance thresholds.
Custom-cultured consortium selected for your specific contamination profile.
Process
We analyze your sludge composition, identify specific PAH compounds and concentrations, and determine the optimal microbial formulation.
Up to 15 microorganisms are selected and cultured in our facility, targeting the specific PAH compounds present in your sludge.
The microbial solution is applied to the sludge. Microorganisms break down PAH molecules through natural biological processes over the treatment period.
Post-treatment testing confirms PAH reduction levels meet regulatory thresholds. Treated sludge is cleared for beneficial land application.
Impact
100% organic treatment. No toxic chemicals introduced to the sludge or environment.
Documented contamination reduction enabling regulatory compliance for land application.
Natural biological treatment converts waste into a beneficial soil amendment resource.
