Reuse Applications

Treated municipal wastewater can be reused for irrigation, industrial cooling, toilet flushing, and groundwater recharge

Water Reuse

Tertiary-treated effluent suitable for cooling towers, washdown, irrigation, and process make-up. Reduces freshwater consumption by 30-70% with appropriate treatment.

Biogas Recovery

Anaerobic treatment of high-COD waste produces 0.35-0.45 m³ biogas per kg COD removed. Can displace 15-30% of natural gas in boilers or generate electricity via CHP.

Protein & Nutrient Recovery

Concentrated protein streams from rendering and processing can be recovered for animal feed or fertiliser. Screening and DAF concentrate solids for valorisation.

Fat & Oil Recovery

CPI and DAF separators recover valuable fats and oils from wastewater. Recovered tallow and grease have commercial value for biofuel and oleochemical industries.

Land Application

Treated effluent with controlled nutrient content can be applied to agricultural land as fertiliser. Requires nitrogen and phosphorus balancing to prevent over-application.

Cost Offset

Resource recovery outputs and reduced disposal requirements can reduce treatment overheads by 10-30%. Detailed feasibility studies quantify performance targets before investment.

Advanced Treatment

Our reuse systems include membrane filtration, UV disinfection, and advanced oxidation to produce high-quality reclaimed

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.

Benefits

Water reuse provides drought-resistant water supply, reduces wastewater discharge, and supports sustainable water manage

Reduced Operating Requirements

Efficient process design, energy optimisation, and automated chemical dosing cut power and reagent bills by 20-40% compared to conventional plants.

Environmental Compliance

Consistently meets discharge consent limits, avoiding fines, prosecutions, and reputational damage. Monthly compliance reports satisfy regulators.

Water Reuse Potential

High-quality effluent suitable for non-potable applications — cooling tower make-up, washdown, and irrigation — reducing freshwater consumption.

Operational Reliability

Duty/standby equipment, automated controls, and predictive maintenance minimise downtime. 95-98% availability targets with rapid response support.

Future Expansion

Modular design with spare connection points and over-sized aeration capacity allows 30-50% flow increase with minimal additional Capital expenditure.

Sustainability Credentials

Energy-efficient design, biogas recovery, and water reuse support BREEAM, LEED, and corporate ESG targets. Demonstrable carbon footprint reduction.

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.
