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.
Regional brewery producing 850 m3/day of process wastewater with COD 4,200 mg/L, BOD 2,800 mg/L, TSS 1,200 mg/L, and variable pH 4.5-9.5 due to CIP cycles. Effluent must meet sewer discharge standards of COD <500 mg/L and BOD <300 mg/L.
Step-by-step process configuration from raw wastewater to compliant discharge.
6 mm drum screen removes spent grain and packaging debris. Equalization tank with 16-hour retention balances flows and pH between production and CIP cycles.
DAF system with pressurised dissolved air flotation removes suspended solids, fats, and hop resins. Ferric chloride coagulant and anionic polymer achieve 85% TSS removal.
Two-stage MBBR with 65% fill ratio achieves 92% COD removal. Aeration at 4.5 mg/L DO. HRT 18 hours. Biofilm carriers handle variable organic loads without sludge bulking.
Lamella clarifier separates biological sludge from MBBR effluent. Recycled activated sludge maintains biomass concentration. Clarified effluent TSS <30 mg/L.
Multi-disc screw press thickens waste biological sludge from 1.2% to 18% solids. Low energy consumption at 1.2 kWh/tonne. Cake suitable for agricultural land application.

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.
| Pre-Treatment | Screening, grit removal, and flow equalisation |
| Primary Treatment | DAF or lamella clarification for solids and oil removal |
| Secondary Treatment | Biological oxidation (activated sludge, MBBR, or SBR) |
| Tertiary Treatment | Filtration, UV disinfection, or chemical polishing |
| Sludge Management | Thickening and dewatering via belt press or centrifuge |
| Control System | PLC with HMI touchscreen and optional SCADA integration |
