Broiler hygiene is not controlled by one wash or one chemical.

It is controlled across the full process: receiving, scalding, defeathering, evisceration, chilling, packing and storage.

The biggest hygiene risk in broiler processing is transfer; bird to bird, equipment to carcass, water to product, and people to surfaces.

That is why hygiene controls need to be applied at the right point in the process, not only at the end of production.

HOCl, the active chemistry in ECA/anolyte, works by oxidising key microbial structures. It disrupts cell membranes, proteins and enzymes, which helps reduce microbial load when correctly applied, monitored and verified.

But HOCl is not a shortcut.

It still needs proper cleaning first, the correct free available chlorine level, suitable pH, contact time, water quality control, and verification records to prove that the intervention is working.

In broiler plants, this matters especially around high-transfer areas such as defeathering, evisceration and chilling.

A University of Pretoria poultry processing evaluation found that anolyte applied immediately after defeathering produced a significant average reduction in total bacterial numbers compared with standard practice.

The lesson is practical:
Don’t just sanitise.
Control the point of risk.

If you've ever experienced recurring microbiological failures despite following cleaning procedures, biofilm could be part of the problem.

Biofilm can develop in hidden areas throughout a facility, protecting microorganisms and creating ongoing contamination risks.

This infographic highlights some of the most common biofilm hotspots found in food and beverage manufacturing environments.

As a CEA Group company, Advanced Hygiene Solutions (AHS) combines ECA technology with practical hygiene expertise, while leveraging the broader engineering, water treatment and food processing capabilities of the CEA Group.

Together, we help customers identify potential biofilm risks, improve hygiene programmes and implement solutions that support safer food production.

Food safety starts with the basics: clean water, effective hygiene, and practical solutions that work in real production environments.

At AHS, a CEA Group Company, we specialise in ECA / HOCl technology for food-safe hygiene applications. But we also bring a wider support network through the CEA Group, with access to engineering, water treatment, chemical, project and technical service capabilities.

That means we can support customers beyond a single product, from hygiene technology to broader plant, water and process needs.

Simple. Practical. Supported.

Why do conventional water spray systems fail against fine airborne dust?

Because water alone cannot effectively capture hydrophobic mineral particles.

Standard water has a high surface tension, causing droplets to bead and roll off particles such as:
- Coal dust
- Iron ore fines
- Silica particles
- Gold ore dust

Our Advanced Airborne Dust Suppression Technology changes the physics completely.

Through precision-dosed surfactants, we reduce water surface tension from approximately 72 mN/m to below 30 mN/m, allowing micro-droplets to instantly wet, capture, and agglomerate airborne particles.

Combined with Dry Fog atomization technology, the system creates ultra-fine droplets between 1-10 microns that collide with PM2.5 and PM10 particles before they spread throughout your plant.

The outcome: ✅ Cleaner working environments ✅Lower water usage
✅ Improved equipment reliability ✅Better environmental performance
✅ Enhanced workforce safety

Engineering and chemistry working together to solve modern dust challenges.

Dust isn't just a visibility problem, it's an operational, environmental, and safety risk.

Our Advanced Airborne Dust Suppression Systems are engineered specifically for highdemand mining and bulk material handling environments where traditional water spray systems fall short.

By combining: ✓ High-pressure atomization ✓ Precision Dry Fog technology
Advanced surfactant chemistry
..we target PM2.5 and PM10 airborne particles at the molecular level.

The result? ✅Up to 99% airborne dust reduction ✅Up to 90% less water
consumption ✅Minimal moisture addition to protect ore quality ✅Improved
compliance with silica dust regulations ✅Reduced re-entrainment on stockpiles and transfer points.

Modern mining requires more than "just water." It requires engineered performance.

💡 Why treating Hexavalent Chromium isn’t as simple as adding chemicals

Reducing Cr(VI) to Cr(III) is a multi-step process, not a single reaction:

1️⃣ Acidic Reduction (pH 2–3)
Fast and effective conversion to Cr(III)

2️⃣ Alkaline Precipitation (pH 7.5–9)
Transforms chromium into an insoluble solid

3️⃣ Co-precipitation
Iron forms hydroxides that help trap and remove contaminants

⚠️ Miss one step - and efficiency drops fast.

Real-world challenges include:
• Dissolved oxygen consuming your reagent
• Other contaminants interfering with reactions
• Higher dosing required to compensate

The takeaway?
👉 Good results come from process control, not just chemical addition.

Beyond the Movie: The Real Science of Clean Water 💧

Most of us remember the movie Erin Brockovich, where one woman took on a giant to protect a town from "Chrome 6."

At CEA Group, we deal with the reality of Hexavalent Chromium [Cr(VI)] every day. It’s one of the most challenging contaminants to treat because the chemistry is so sensitive.
This week, we’re highlighting that Chemistry Alone Isn’t Enough.

To truly protect our water, you need:
✅ Precise pH Control: Moving from acidic to alkaline stages without error.
✅ Smart Dosing: Accounting for "real-world" factors like dissolved oxygen.
✅ Robust Engineering: Ensuring that what happens in the lab actually works in the plant.

We’re encouraging everyone to revisit the story of Erin Brockovich. It’s a powerful reminder of why we do what we do at CEA - providing the technology and expertise to ensure industrial water is safe for everyone.

⚠️ Hexavalent Chromium in your water? That’s not just a compliance issue - it’s a serious risk.

Cr(VI) is highly toxic and commonly found in industrial wastewater, especially from plating processes.

The solution isn’t just removal - it’s chemical transformation.

💡 Using Ferrous Sulphate (FeSO₄):
🔹 Cr(VI) is reduced to the safer Cr(III) form
🔹 Then precipitated and removed from the water
🔹 Supported by iron acting as a natural coagulant

But here’s where it gets critical:
⚙️ pH control (acidic → alkaline stages)
⚙️ Correct dosing (often well above theoretical)
⚙️ Managing competing reactions (oxygen, organics)

Done right, this process delivers:
✅ Effective detoxification
✅ Reliable removal
✅ Improved treatment stability

This isn’t just treatment - it’s precision chemistry in action.
