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.
Village wastewater treatment plant serving 500 PE with failing oxidation ditch, frequent sludge bulking, and effluent BOD averaging 45 mg/L against a discharge consent of 25 mg/L. Available footprint limited to 6m x 12m. Requires upgrade to 1,000 PE capacity for new housing development.
Step-by-step process configuration from raw wastewater to compliant discharge.
Existing oxidation ditch capacity and performance audited. Sludge volume index measurements confirmed severe bulking (SVI 380 mL/g). Effluent quality data reviewed against consent conditions.
Two-container MBR plant designed: biological container with anoxic/aerobic chambers and membrane tank; process container with screens, blowers, dosing, and control. Total footprint 6m x 12m.
Submerged flat-sheet membranes with 0.04 micron pore size. MLSS maintained at 10-12 g/L. Automatic membrane relaxation and chemically enhanced backwash (CEB) every 24 hours.
Full SCADA system with HMI touchscreen, remote access via VPN, SMS alarms, automatic data logging for regulatory reporting. Unattended operation capability.
MBR effluent consistently achieves BOD <10 mg/L, TSS <5 mg/L, ammonia <2 mg/L. Meets EU Urban Waste Water Directive for stream discharge. Capacity upgrade to 1,000 PE achieved.

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.
