Poultry processing plant generating 1,200 m3/day of wastewater with BOD 3,500 mg/L, TSS 2,000 mg/L, fat 1,500 mg/L, total nitrogen 280 mg/L, and variable temperature 15-35°C. Must meet sewer discharge BOD <600 mg/L, TSS <300 mg/L, fat <50 mg/L. Client wants to recover fat for rendering.
Step-by-step process configuration from raw wastewater to compliant discharge.
3mm drum screen removes feathers, viscera, and large solids. Aerated grit chamber removes sand and bone fragments. Protected downstream equipment from damage and blockages. Screenings sent to rendering.
High-rate DAF with heated water (35°C) and cationic polymer achieves 90% fat removal. Recovered float at 12% solids pumped to fat storage tank for rendering. DAF effluent fat <40 mg/L. Recovered fat value offsets treatment costs.
UASB reactor operating at 35°C treats 70% of organic load. HRT 18 hours. Biogas production 3,200 m3/day replacing 30% of boiler fuel. Effluent BOD 900 mg/L. pH maintained with alkali dosing.
Moving bed biofilm reactor with 65% carrier fill achieves nitrification and BOD polishing. 16-hour HRT. Fine bubble aeration. Final BOD <200 mg/L. Nitrogen <30 mg/L via simultaneous nitrification-denitrification.
Combined biological and DAF sludge thickened via gravity to 5% then dewatered through multi-disc screw press to 18% solids. Cake combined with screenings for rendering. Low energy at 1.0 kWh/tonne. Filtrate returned to headworks.

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 |
| Chemical Dosing | Automated coagulant, flocculant, and pH correction |
| Materials | SS316L, duplex, or rubber-lined carbon steel |
85 – 98% chemical oxygen demand reduction depending on process configuration and influent variability.
90 – 99% suspended solids reduction through combined physical and biological treatment stages.
