The food and beverage industry produces large volumes of contaminated wastewater every day. Fats, oils and organic matter significantly increase the level of contamination. At the same time, local authorities are tightening the requirements for wastewater discharge. Operators therefore need reliable technologies that combine high treatment performance with transparent process monitoring.
This is precisely where PPU Umwelttechnik comes in.
We develop and manufacture containerised and stationary ClearFox® pressure-relief flotation systems for industrial applications. Our systems reliably remove fats, oils, suspended solids and organic contaminants from process effluent. At the same time, we integrate state-of-the-art measurement, control and regulation technology that records all key process data in real time.
This combination of proven process engineering and intelligent automation enhances operational reliability, reduces operating costs and ensures maximum transparency.
The food industry places high demands on wastewater treatment
Food processing generates wastewater containing high concentrations of fats, oils and organic matter. Catering businesses, commercial kitchens, dairies, breweries and manufacturers of ready meals produce highly polluted wastewater streams on a daily basis.
Without pre-treatment, these substances enter the sewer system. There, they cause deposits, increase maintenance costs and place a strain on municipal sewage treatment works. Many local authorities therefore require pre-treatment of the wastewater. Operators must demonstrate compliance with defined limit values and document their processes.
ClearFox® Dissolved Air Flotation reliably reduces pollution
Our ClearFox® pressure-relief flotation removes solids, fats, oils, hydrocarbons and organic pollutants from industrial wastewater. The process utilises ultra-fine air bubbles that transport contaminant particles to the surface. There, the system continuously separates the floating substances from the water.
In typical applications within the food industry, our DAF reduces the chemical oxygen demand (COD) by more than 70 per cent. At the same time, the system automatically regulates the pH to the desired range between 6.5 and 7.5.
The result is stable and traceable effluent quality.
Modern measurement technology provides complete transparency
A high-performance treatment plant requires more than just good process engineering.
That is why we integrate modern measurement technology from leading manufacturers such as Endress+Hauser directly into our plants. Sensors continuously record all key operating data. The control system processes this information in real time and reacts immediately to changes in the process.
Operators have a complete overview of their plant at all times.
The measurement technology monitors, amongst other things:
• pH value
• Levels
• Flow rates
• Operating conditions
• Wastewater treatment process data
This data provides transparency for operators, regulatory authorities and service teams.
Industry 4.0 begins in wastewater treatment
Digitalisation is transforming industry. The water and wastewater sector is no exception. Our plants operate fully automatically. The control system manages the process, regulates chemical dosing and monitors all relevant operating parameters. Staff can focus on production, whilst the plant reliably handles wastewater treatment. An optional remote monitoring system also provides access to all key operating data. Operators can track plant status in real time and access the control system directly if necessary. This digital connectivity enhances operational reliability and significantly speeds up service processes.Continuous development creates long-term added value
Technology is constantly evolving. That is why we, too, are continuously developing our systems.
Regular training, dialogue with technology partners and new insights gained from international projects are directly incorporated into our plant designs. Our collaboration with Endress+Hauser particularly strengthens our expertise in the fields of measurement technology, automation and digital process monitoring.
This results in solutions that combine high-performance cleaning with modern digitalisation.
Conclusion
Industrial wastewater treatment faces new challenges. Operators require high-performance process technology, reliable measurement systems and maximum transparency.
Our ClearFox® pressure-relief flotation plants meet precisely these requirements. They reliably remove fats, oils and organic contaminants from wastewater streams in the food and beverage industry. State-of-the-art measurement and control technology monitors every step of the process. Fully automated processes and digital remote monitoring provide additional security.
In this way, we combine efficient wastewater treatment with the requirements of Industry 4.0.
