Engineered chemicals targeting quick kinetic biological denitrification pathways and optimized flocculation processes.
The Metropolitan Area of Barcelona and the broader Catalonia region face dual pressure from chronic water scarcity and strict EU environmental mandates. Water basins fed by the Llobregat and Besòs rivers present high concentrations of nitrates due to historical agricultural runoff and dense urban industrial activities. Consequently, local wastewater facilities (EDARs) are continually under pressure to maintain optimal biological denitrification to prevent eutrophication in regional tributaries and coastal Mediterranean waters.
Under the European Union’s Water Framework Directive (WFD) and local rules established by the Catalan Water Agency (ACA - Agència Catalana de l'Aigua), total nitrogen (TN) discharges in sensitive areas must not exceed 10 mg/L. To reach these aggressive targets without requiring massive expansions of physical bioreactor footprints, plant operators must optimize their denitrification processes. This is achieved through the dosing of highly precise, high-purity external carbon sources like Smedic's Pure Solid Sodium Acetate, which fuels the heterotrophic microbiological conversion of nitrates ($NO_3^-$) to harmless gaseous nitrogen ($N_2$).

Industrial processes in sectors such as pharmaceutical manufacturing around the Vallès Occidental belt, food processing plants in the Penedès area, and petrochemical complexes in nearby Tarragona generate highly variable wastewater matrices. Traditional carbon sources like methanol present high safety and flammability risks (ATEX regulations in EU plants) and suffer from low reaction kinetics in colder winter temperatures.
Smedic Solid Sodium Acetate ($CH_3COONa$) presents a highly stable, non-toxic, and hazard-free alternative. From a biochemical kinetic perspective, sodium acetate is utilized by denitrifying bacteria directly through the metabolic cycle without requiring preliminary enzymatic hydrolysis (unlike complex sugars or starches). This yields a significantly faster specific denitrification rate ($q_D$), ensuring total nitrogen compliance even during seasonal peak loads or low-temperature shocks common in the winter months along the Besòs basin.

Pioneering smarter carbon dosing to achieve energy neutrality in wastewater reclamation.
As the European Union moves toward a climate-neutral circular economy, the municipal water sector is shifting from simple treatment to comprehensive resource recovery. EDAR plants in the Barcelona metropolitan area are striving for energy-neutral operations. Smedic is supporting this transition by engineering composite carbon sources with optimized biological availability, reducing the overall carbon footprint per kilogram of nitrogen removed.
Additionally, we are partnering with digital control specialists to support feedforward algorithmic dosing of sodium acetate. By pairing real-time Nitrate/COD probe sensors with automated pumps, plants can minimize carbon source wastage, reduce chemical sludge generation, and dramatically lower operational expenditures (OPEX).
