Systems designed and guaranteed to meet specific effluent quality targets for discharge or reuse applications.
Custom automation and SCADA integration for critical water treatment processes plants.
Seamlessly integrate new water treatment equipment with your existing infrastructure.
Complete turnkey water treatment plants from initial concept through commissioning.
Comprehensive support packages including preventive maintenance, remote diagnostics, operator training and genuine spare parts.
Contractual commitments backed by engineering confidence and financial security.
Effluent COD, BOD, TSS, and nutrient limits are written into the purchase contract with liquidated damages for non-performance. Targets are achievable and based on validated process design.
Performance guarantees are underpinned by pilot test data from your actual wastewater. We do not offer theoretical guarantees — every commitment is validated with real operating evidence.
Performance bonds and retention clauses protect your investment during the warranty period. We stand behind our designs with real financial commitment, not just promises.
If performance falls short, we rectify at our cost. This may include equipment modification, process adjustment, or supplementary treatment — all within the original contract scope.
We guarantee system availability of 95-98% excluding scheduled maintenance. Redundant duty/standby arrangements and rapid spare parts supply ensure continuous operation.
Specific energy consumption targets are agreed for aeration, pumping, and sludge handling. Power consumption above the guaranteed level is rectified at our expense.
Multiple verification layers ensure your system performs before it is built.
CFD analysis validates flow distribution, residence time, and dead-zone elimination. We optimise inlet and outlet geometry to prevent short-circuiting and ensure uniform treatment.
Steady-state and dynamic process models predict performance across the full operating envelope. We simulate diurnal load variations, shock loads, and seasonal temperature changes.
On-site pilot plants validate theoretical design with real wastewater. Data refines loading rates, chemical doses, and retention times to de-risk full-scale implementation.
Virtual walkthroughs with your operations team identify maintenance access issues, lifting conflicts, and safety hazards before steel is cut.
Hazard and operability studies identify process safety risks, environmental releases, and equipment failure scenarios. Mitigation measures are designed in from the outset.
Independent chartered engineers review our process calculations, mechanical design, and control logic. Third-party verification adds confidence for lenders and insurers.
Our guarantees are structured to align with regulatory reporting conventions and protect both parties:
Liquidated damages are capped at 5–10% of contract value, with a performance bond (typically 10% of contract) held until successful completion of the Provisional Acceptance Test (PAT).
Regulatory permits increasingly specify percentile-based limits. We design and demonstrate compliance using robust statistical methods:
| Statistic | Typical Permit Requirement | Our Design Margin |
|---|---|---|
| Annual average | Mean < X | Design for 0.8× limit |
| Monthly average | Mean < X | Design for 0.85× limit |
| Weekly average | Mean < X | Design for 0.9× limit |
| 95-percentile | 95%ile < X | Design for 0.85× limit |
| 99-percentile | 99%ile < X | Design for 0.9× limit |
| Maximum | Instantaneous < X | Alarm at 0.8×; trip at 0.95× |
Sample size (n) per reporting period is calculated to achieve a confidence interval of ±10% on the estimated mean at 95% confidence, typically requiring n ≥ 30 for monthly reporting of continuous parameters.
The PAT demonstrates that the plant meets guaranteed performance under real operating conditions. The standard PAT comprises 30 consecutive days of operation at design throughput (±10%). Effluent is sampled and analysed daily for all guaranteed parameters by a UKAS- or MCERTS-accredited laboratory. Acceptance criteria: (a) no single grab sample exceeds 1.2× the guarantee limit; (b) the 30-day arithmetic mean is <0.95× the guarantee limit; (c) availability during the test period is ≥95%. If the PAT fails, a 14-day rectification period is granted, followed by a retest. Final Acceptance occurs 12 months after PAT, confirming sustained performance and verifying that seasonal variations are accommodated.
Specific energy consumption (SEC) is benchmarked against typical ranges: DAF clarification 0.03–0.08 kWh/m³; activated sludge 0.3–0.6 kWh/m³; MBR 0.5–1.2 kWh/m³. Guarantees are expressed as kWh/m³ treated or kWh/kg COD removed, with correction factors for inlet temperature and COD load. Power monitoring uses Class 0.5S energy meters with 15-minute interval logging.
Availability A = MTBF / (MTBF + MTTR), where MTBF is mean time between failures and MTTR is mean time to repair. We target MTBF > 8,000 h for mechanical equipment and MTTR < 4 h for critical items (pumps, blowers) by holding on-site spare parts. Duly/standby configurations for all critical rotating equipment ensure repair can occur without plant shutdown.
Transparent, continuous verification that your system meets its guarantees.
Flow, pH, COD, TSS, ammonia, and phosphate analysers provide real-time performance data. Instruments are calibrated weekly and verified against laboratory reference methods monthly.
Operator screens display current performance against guarantee limits with green/amber/red indicators. Automatic alerts trigger when parameters drift towards non-compliance.
Automated performance reports compare actual effluent quality against contractual targets. Daily maxima, monthly averages, and percentile statistics demonstrate continuous compliance.
Quarterly performance audits by our process engineers verify instrument accuracy, control loop tuning, and maintenance practices. Recommendations prevent gradual performance degradation.
Secure cloud portal gives your environmental manager, board, and regulator read-only access to live and historical performance data. Transparency builds trust and simplifies audits.
Vibration, temperature, and run-hour trending identifies equipment degradation before failure. Maintenance is scheduled during planned shutdowns, not after emergency breakdowns.
How we match treatment technology to your performance targets based on contaminant profile, flow variability, and discharge standard.
Not every process can achieve every target. The matrix below guides technology selection based on typical achievable effluent quality:
| Technology | BODâ‚… (mg/L) | TSS (mg/L) | NHâ‚„-N (mg/L) | TN (mg/L) | TP (mg/L) |
|---|---|---|---|---|---|
| Primary DAF | 80–150 | 20–50 | — | — | — |
| Activated Sludge (CAS) | 10–25 | 15–30 | 1–5 | 15–25 | 1–3 |
| MBBR + Clarifier | 10–20 | 15–25 | 1–3 | 10–20 | 0.5–2 |
| MBR | 3–10 | < 5 | < 1 | 5–15 | 0.3–1 |
| MBR + Reverse Osmosis | < 3 | < 1 | < 0.5 | < 3 | < 0.1 |
Decision criteria: If your permit requires TSS < 10 mg/L, MBR or post-filtration is mandatory. If TN < 10 mg/L is required, anoxic zones with internal recycle (200–400%) and MLE or Bardenpho configuration are necessary.
We define measurable KPIs that align operator behaviour with guarantee compliance:
KPIs are displayed on the SCADA dashboard with automatic traffic-light colouring. Monthly management reports trend each KPI against target with 12-month rolling averages.
