Understanding Surcharges

Municipalities often impose surcharges on industrial discharges that exceed standard strength wastewater parameters. The right pre-treatment removes those surcharges.

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.

Additional Benefits

Beyond compliance benefits, pre-treatment protects downstream municipal infrastructure, reduces the risk of discharge vi

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.

Industrial Pre-treatment Systems

Industrial pre-treatment protects municipal sewer networks, enables water reuse, and ensures compliance with trade effluent consents. Our engineered pre-treatment trains combine screening, oil separation, chemical precipitation, and pH correction to condition wastewater before discharge or further biological treatment. Each system is sized for peak flows and shock loads typical of your industrial sector.

Screening & Grit Removal

Removes solids that could damage pumps, block pipework, or settle in sewers.

Oil & Grease Separation

API separators, coalescing plate packs, and DAF units remove free and emulsified oils.

Chemical Precipitation

Coagulation and flocculation remove heavy metals, phosphates, and colloidal solids.

pH Correction

Automated acid/alkali dosing neutralises extreme pH to protect downstream biology.
