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.
Onshore oil field producing 500 m3/day of produced water with oil 150 mg/L, TDS 12,000 mg/L, H2S 25 mg/L, and suspended solids 300 mg/L. Client requires treated water with oil <5 mg/L for reinjection to maintain reservoir pressure. Water recovery target 65%.
Step-by-step process configuration from raw wastewater to compliant discharge.
Corrugated Plate Interceptor (CPI) separator removes free oil and large solids. 45-minute retention, plate spacing 20 mm. Oil skimmer recovers crude for resale. Effluent oil reduced to 45 mg/L.
IGF unit with microbubble generation removes emulsified oil to <10 mg/L. Automated chemical dosing of demulsifier and flocculant optimises oil bubble attachment and separation.
DAF system provides final oil removal achieving <5 mg/L. Coagulant and polymer dosing ensures fine oil droplet capture. Skimmings returned to CPI separator.
Spiral-wound RO membranes desalinate DAF effluent from 12,000 to <500 mg/L TDS. Two-pass configuration with energy recovery. 65% water recovery, 35% brine to evaporation pond.
Packed column air stripping removes H2S from <0.5 mg/L. UV disinfection ensures <100 CFU/100mL for reinjection. SCADA-controlled automatic operation.

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.
Tertiary treatment enables up to 80% water recycling for non-potable process applications.
