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.
Seasonal brewery producing 500 m3/day with COD 7,500 mg/L, BOD 4,800 mg/L, colour 600 Pt-Co, and suspended solids 2,200 mg/L. Operation only 8 months/year — advanced biological treatment not viable due to seasonal shutdown. Needs fully chemical/physical process achieving COD <500 mg/L.
Step-by-step process configuration from raw wastewater to compliant discharge.
2mm drum screen removes spent grain. Heated DAF (38°C) with alum (250 mg/L) and polymer removes 82% of suspended solids and 90% of fats. Float at 8% solids diverted to rendering. DAF effluent COD 5,200 mg/L, TSS 350 mg/L.
Two-stage chemical conditioning and treatment: ferric chloride (180 mg/L) at pH 5.5 for colour removal, then pH raised to 7.5 with caustic soda for metal hydroxide precipitation. Anionic polymer aids flocculation. 45-minute total reaction time. COD reduced to 2,800 mg/L.
Lamella clarifier captures coagulated precipitate at 8 m/h upflow velocity. Effluent COD 2,200 mg/L, TSS <25 mg/L. Automatic desludging to thickener. Underflow at 4% solids. Overflow turbidity <5 NTU.
Ozone generator producing 2.0 kg O3/h contacts clarified effluent in 20-minute counter-current column. Direct oxidation destroys colour compounds and recalcitrant organics. COD reduced from 2,200 to 650 mg/L. Colour <50 Pt-Co. Residual ozone destroyed with catalytic destructor.
Downflow GAC column (1.5 m diameter, 30 min EBCT) adsorbs residual organics. Effluent COD consistently <450 mg/L meeting sewer discharge. Automatic backwash every 48 hours. Carbon replaced quarterly based on breakthrough monitoring.

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.
