Upgrade Drivers

Treatment plants require upgrades to increase capacity for population growth, meet stricter discharge limits, replace ag

Engineered Performance

Every system is designed for your specific wastewater characteristics, flow profile, and effluent targets. No off-the-shelf assumptions — just validated process engineering.

Proven Reliability

Equipment selected from manufacturers with proven field performance in similar applications. Duty/standby arrangements and robust construction minimise unplanned downtime.

Environmental Compliance

Design targets are set at 50-70% of consent limits, providing a safety margin for process variation. Continuous monitoring and automated reporting demonstrate compliance.

Operator Friendly

Intuitive controls, clear instrumentation, and accessible maintenance points reduce training requirements. Standard operating procedures written in plain language.

Technical Support

Direct access to our process engineers for operational advice, troubleshooting, and optimisation. Remote diagnostics and rapid on-site response keep your plant running.

Quality Assurance

Materials certified to EN 10204 3.1, welding procedures qualified to ISO 9606, and pressure testing to 1.5x design pressure. Full traceability from mill to commissioning.

Retrofit Solutions

We design retrofits that maximise use of existing infrastructure while adding new processes or capacity. This minimises

Municipal Wastewater Treatment Process

Municipal wastewater treatment protects public health and receiving waters by progressively removing solids, organic matter, nutrients, and pathogens from sewage. Our engineered solutions address the unique challenges of municipal flows including diurnal variation, stormwater ingress, seasonal population changes, and increasingly stringent discharge standards.

Preliminary Treatment

Screening, grit removal, and flow equalisation protect downstream processes from damage and overload.

Primary Clarification

Gravity separation of settleable solids achieving 50-70% TSS and 25-40% BOD removal.

Biological Treatment

Activated sludge, MBBR, or SBR processes remove dissolved organics and enable nutrient control.

Tertiary & Disinfection

Filtration, UV, or chemical disinfection guarantees compliance with bathing water and reuse standards.

Plant Design Parameters

Design Flow50 – 500,000 PE (population equivalent)
Dry Weather Flow150 – 250 L/PE/day
BOD Loading50 – 70 g/PE/day
TSS Loading60 – 90 g/PE/day
Nitrogen Loading8 – 12 g/PE/day
Phosphorus Loading1.5 – 3.0 g/PE/day
Hydraulic Retention4 – 12 hours (biological stage)
Sludge Production30 – 50 g DS/PE/day

Discharge Standards & Compliance

Urban Wastewater Directive

EU 91/271/EEC compliance for BOD, COD, TSS, and nutrient removal based on plant size and sensitivity.

Bathing Water Standards

Enhanced disinfection and nutrient removal for coastal and recreational water discharges.

Water Reuse Regulations

Compliance with REGULATION (EU) 2020/741 for agricultural irrigation and industrial reuse.
