Chiller Water Characteristics

Poultry chiller overflow contains water-soluble proteins, fats, and microorganisms picked up during the cooling process.

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.

Treatment Approach

DAF flotation effectively removes the protein and fat content from chiller water. The large flow volumes are handled wit

1. Site Assessment

Comprehensive analysis of wastewater volume, quality, temperature, and variability informs process selection and equipment sizing for optimal performance.

2. Process Design

Treatment train selected from screening, DAF, biological, filtration, and disinfection options based on effluent targets, footprint, and Capital expenditure constraints.

3. Equipment Selection

Materials, pumps, blowers, and instruments specified for the specific duty conditions, chemical environment, and operational maintenance capabilities.

4. Automation & Control

PLC-based control with online monitoring automates chemical dosing, aeration, and sludge withdrawal. Remote access provides 24/7 oversight.

5. Commissioning

Site acceptance testing verifies mechanical, electrical, and process performance. Operator training ensures confident day-to-day management.

6. Performance Guarantee

Contractual effluent targets with financial backing demonstrate our confidence. Monthly reporting proves continuous compliance for regulators and stakeholders.

Water Reuse Potential

Treated chiller water can be recycled for non-potable applications such as equipment washing, reducing freshwater consum

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.

Poultry Wastewater Treatment Process

Poultry processing wastewater is characterised by high organic loads, blood, fats, oils, feathers, and suspended solids. Treatment trains typically combine screening, DAF flotation for fat and protein recovery, biological oxidation for dissolved organics, and disinfection for pathogen control. Water reuse systems can recycle up to 70% of process water for non-potable applications.

Protein Recovery

DAF systems capture protein-rich solids for rendering or animal feed ingredient production.

Fat & Oil Separation

High-efficiency flotation removes poultry fat for recovery as tallow or biodiesel feedstock.

Pathogen Control

UV or chlorination systems ensure compliance with microbiological discharge standards.

Water Reuse

Membrane filtration and advanced oxidation enable recycling for equipment washdown.
