This is an illustrative scenario showing how Reynolds & Bauhm equipment can be configured for this application. Every site has unique requirements — contact us for a solution tailored to your specific wastewater characteristics.
Pharmaceutical manufacturing facility generating 120 m3/day of wastewater with COD 8,000 mg/L, containing active pharmaceutical ingredients (APIs) at trace concentrations, solvents, and high salt content. Must meet sewer discharge COD <500 mg/L and eliminate API residues before advanced biological treatment plant.
Step-by-step process configuration from raw wastewater to compliant discharge.
24-hour flow-balanced equalization with online COD, pH, and conductivity monitoring. Batch sampling identifies API concentration peaks triggering diversion to holding tank for controlled release.
Fenton oxidation with Fe2+/H2O2 at pH 3.0-3.5 destroys recalcitrant organics and APIs. 2-hour reaction in baffled reactor. COD reduced from 8,000 to 2,500 mg/L. Hydroxyl radicals mineralise pharmaceutical compounds.
Moving bed biofilm reactor with 70% carrier fill handles high organic load and salt stress. 24-hour HRT. Denitrification zone for nitrogen removal. COD reduced to 400 mg/L.
Granular activated carbon columns adsorb residual organics and trace APIs. Two-column lead-lag configuration. 30-minute EBCT. Effluent COD <200 mg/L with non-detectable API residues.
UV-C reactor provides final disinfection ensuring <10 CFU/100mL. Effluent meets all sewer discharge parameters. SCADA-controlled automatic backwash and carbon regeneration scheduling.

Reynolds & Bauhm follows a structured engineering methodology for every project. We begin with detailed wastewater characterisation, process selection based on contaminant profiles, pilot testing where required, and full-scale design with performance guarantees. Our multidisciplinary team of chemical, mechanical, and electrical engineers ensures seamless integration of process, mechanical, and control disciplines.
Comprehensive influent analysis including COD, BOD, TSS, heavy metals, pH, temperature, and flow profiling.
Process flow development with P&IDs, mass balances, and hydraulic modelling validated by CFD where appropriate.
On-site pilot trials validate performance guarantees under actual operating conditions before capital commitment.
FAT, SAT, performance trials, operator training, and handover documentation ensuring operational readiness.
