Guard Automation has developed a cutting-edge solution that is transforming wastewater treatment at plants across Norway. In February 2023, this innovative technology was implemented at the Elvika Treatment Plant in Modum Municipality, yielding significant improvements in both chemical use and environmental outcomes.
THE CHALLENGE
Wastewater treatment plants handle thousands of liters of sewage per hour, aiming to remove harmful substances and release clean water back into nature. To achieve this, large quantities of chemical—particularly to remove phosphorus are traditionally required.
However, determining the right chemical dosage has been a longstanding challenge, often leading to inefficiency, environmental strain, and high operational costs. In many municipalities, chemical dosing has historically been manual, relying on educated guesses and requiring regular human intervention. This has resulted in chemical overuse, unnecessary costs, and operational bottlenecks, especially during weather fluctuations such as snowmelt or heavy rainfall.
THE SOLUTION
Treat Smart by Guard Automation offers a predictive, data-driven model that optimises chemical dosing based on real-time external factors such as weather and water conditions. By analysing variables like snowmelt, rainfall, and foreign water levels, the solution adjusts chemical usage dynamically, reducing the need for manual oversight.
RESULTS
After just a few months of implementation at the Elvika Treatment Plant, the results have been remarkable:
- 20% reduction in chemical consumption during peak foreign water levels.
- Improved water clarity and reduced phosphorus discharge.
- Expected annual cost savings for the municipality due to reduced chemical procurement and optimised operational hours.
The success at the Elvika Treatment Plant is just the beginning. With virtual testing at 10 plants across Norway, Guard Automation has proven that the technology can be easily scaled to other treatment plants. The predictive model is adaptable, meaning it can handle varying treatment demands and environmental conditions across different municipalities.
