Recovery Opportunities

Many industrial waste streams contain valuable materials that can be recovered and sold or reused. Oils, metals, fibres and process chemicals can often be recovered for reuse or sale.

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.

Recovery Technologies

DAF flotation systems concentrate oils and suspended solids for recovery. Chemical precipitation captures heavy metals.

Cost Offset

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

Economic Benefits

Resource recovery can offset 20-40% of wastewater treatment operating overheads. The recovered materials generate output wh

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.
