Food Industry Challenges

Food and beverage facilities generate wastewater with high BOD, fats, oils, grease, and suspended solids. These high-str

High Organic Loading

Wastewater streams frequently carry organic loads 5-50x higher than domestic sewage, demanding robust biological or physical-chemical treatment capacity.

Variable Conditions

Temperature, pH, flow, and concentration swings between production shifts create treatment instability without proper equalisation and buffering.

Biological Sensitivity

Shock loads, toxins, or pH extremes can kill beneficial biomass. Protection mechanisms like equalisation and pH correction are essential.

Fat, Oil & Grease

High FOG content causes pipe blockage, flotation cell failure, and membrane fouling. Effective pre-treatment prevents downstream operational issues.

Complex Chemistry

Variable chemical composition from cleaning agents, process chemicals, and raw materials requires adaptable treatment chemistry and dosing control.

Regulatory Pressure

Discharge consents are tightening continuously. Treatment must not only meet current limits but accommodate future reductions without major rebuild.

Treatment Approach

Our food industry pre-treatment systems typically include screening for solids removal, DAF flotation for oil and grease

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.

Compliance & Efficiency

Properly designed pre-treatment can reduce BOD by 60-80% and remove 90%+ of oils and grease, bringing discharges into co

Permit Management

We manage discharge permit applications, amendments, and renewals. Environmental regulators trust our data and engineering credibility, speeding approvals.

Validated Testing

Effluent sampling follows ISO and national standards. Third-party laboratory analysis provides defensible data for regulatory submissions and legal defence.

Audit Readiness

Continuous data logging, calibration records, and maintenance logs are organised for instant retrieval. Environmental audits become routine, not stressful events.

Consent Limits

We design for 50-70% of the consent limit, not 100%. This safety margin absorbs process upsets, seasonal variation, and instrument drift without breach.

Liability Protection

Performance guarantees with financial backing shift liability from your balance sheet to ours. Insurance and bonding protect against worst-case scenarios.

Industry Standards

Design, fabrication, and commissioning follow ISO, EN, and industry-specific standards. Documentation packages satisfy due diligence for lenders and insurers.

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.
