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.
Brewery startup producing 350 m3/day of high-strength effluent with COD 7,000 mg/L, BOD 4,500 mg/L, TSS 1,800 mg/L, and fat 600 mg/L. Site has no space for advanced biological treatment and requires rapid commissioning. Discharge limit COD <500 mg/L. Zero biological processes used – pure chemical and physical treatment.
Step-by-step process configuration from raw wastewater to compliant discharge.
Heated DAF at 35°C with ferric chloride (200 mg/L) and cationic polymer removes 88% of fats and 75% of suspended solids. Float sludge at 10% solids recovered for rendering. DAF effluent COD reduced from 7,000 to 4,800 mg/L. Retention 30 minutes at 0.5 MPa saturation.
Acidified effluent (pH 3.0) treated with FeSO4 (400 mg/L) and H2O2 (1,200 mg/L) in 3-hour reaction tank. Hydroxyl radicals mineralise recalcitrant organics. COD reduced from 4,800 to 1,200 mg/L (75% removal). Residual iron precipitates as hydroxide.
pH raised to 8.5 with hydrated lime for iron hydroxide precipitation. Lamella clarifier captures precipitated iron and organics at 6 m/h upflow. Effluent COD 900 mg/L, TSS <30 mg/L. Sludge at 5% solids dewatered via screw press to 22% cake.
Two-column lead-lag GAC system adsorbs residual organics. EBCT 25 minutes. Lead column breakthrough triggers carbon replacement. Effluent COD <400 mg/L consistently. Spent carbon thermally regenerated off-site.
5-micron cartridge filtration captures any GAC fines. Effluent pH adjusted to 7.0 with CO2. No biological stage required – total treatment time 6 hours from influent to discharge. System operational within 2 weeks of delivery.

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.
