Every industrial process depends on water – and in particular, its quality – whether it’s used as a production ingredient, for auxiliary equipment like boilers or cooling towers, or to ensure safety and compliance for discharge back into the environment after use.
That’s why every company must maintain consistent water quality over time. Any variation can affect the final product, impact operational costs and even result in penalties or fines if the standards set by authorities aren’t met upon release.
Why precision matters in chemical dosing
Chemical dosing is a crucial step in almost every stage of treatment – but you have to get the dose right. Underdosing can compromise product quality, operational efficiency or safety standards. Overdosing wastes chemicals and increases costs, and can potentially impact the environment.
Fluctuating conditions make manual or conventional dosing approaches unreliable. It’s not just about adding chemicals – it’s about adding the right amount, at the right time, with absolute precision. If you can get that right, you can unlock smarter, safer and more effective water treatment.
With the right chemical dosing pumps and solutions, you get:
- Precise dosing with accuracy up to 1% and turndown ratio of up to 3000:1
- Dynamic flow adjustments – ensuring optimal performance, even as system demands fluctuate
- Integrated safety features – protecting equipment, reducing chemical exposure and extending system lifetime
Precision that transforms water treatment
Across industries, the need for chemical dosing is clear: it keeps product quality safe, ensures operational efficiency and protects people and the environment. Whether it’s disinfecting food production lines, optimising wastewater treatment or preventing scaling in membrane systems, accuracy in chemical dosing is the difference between waste and efficiency, compliance and risk, reliability and costly downtime.
By switching from conventional dosing to intelligent, adaptive solutions, you gain control, consistency and cost savings. Grundfos SMART Digital DosingTM pumps provide the real-time precision and flexibility needed to meet even the most demanding conditions – delivering exactly what’s required, no more, no less.
Beyond the DDA, we offer a complete portfolio of chemical dosing pumps and solutions, ensuring smooth, continuous dosing with unmatched accuracy – even at the smallest volumes. Built for operator safety, seamless remote monitoring and real-time process control, these solutions reduce chemical waste and optimise performance for smarter, more efficient water treatment.
Food and Beverage
Eliminating microbial risks in the food industry with disinfection
Hygiene is non-negotiable in the food industry. Inaccurate chemical dosing in disinfection can impact taste and safety and lead to inadequate microbial control. Disinfectants like chlorine, hydrogen peroxide and peracetic acid are volatile and prone to degassing. When production pauses, air bubbles can form in suction lines or dosing heads, causing underdosing when operations resume and ultimately compromising microbial control.
Traditional dosing pumps typically struggle with degassing. Grundfos SMART Digital DosingTM pumps with Flow Control Monitoring (FCM) detect and eliminate air bubbles via a built-in degassing function, ensuring consistency and maintaining precise dosing.
That way you get reliable microbial control, no unexpected shutdowns and complete peace of mind.
Ensuring 99.99% pathogen removal in food sanitation
Clean Works, a food sanitation startup, needed a dosing pump capable of precise atomisation to disinfect produce and PPE during the COVID-19 pandemic. By switching to Grundfos DDA FCM pumps, they eliminated pulsation issues, reduced maintenance time and achieved continuous, controlled dosing – ensuring 99,99% pathogen removal while conserving critical resources.
Wastewater treatment
Reducing sludge and costs in wastewater treatment
Efficient coagulation and flocculation also depends on precise chemical dosing. Underdosing leads to poor solids separation, which can overload filters and membranes. If the suspended solids are not within the expected range, filtration steps can be severely affected. Overdosing, on the other hand, can lead to excessive chemical use and increased sludge production – driving up transport, treatment and disposal costs.
Grundfos SMART Digital DosingTM pumps incorporate the Slow Mode function, which enables handling of high-viscosity coagulants with precision, ensuring the right chemical balance. This improves sludge dewatering, optimises filtration and reduces both chemical waste and operational expenses.
Improving groundwater quality for compliance
At Halzhausen WWTP, where treated wastewater directly impacts groundwater quality, precise dosing of ferric chloride was critical for removing contaminants. Five Grundfos DDA dosing pumps were integrated to optimise chemical usage and ensure compliance with strict discharge regulations. This resulted in consistently clean effluent, minimal environmental impact and enhanced operational efficiency.
Maximising performance and minimising scaling in membrane separation
In membrane separation processes like reverse osmosis, scaling can affect membrane longevity and system efficiency. To prevent this from happening and reduce the need for frequent clean-in-place procedures, antiscalants are employed – but both underdosing and overdosing has consequences.
- Underdosing can lead to permanent fouling and costly membrane replacements,
- Overdosing wastes chemicals and increases operational costs.
Fluctuating system conditions like flow and pressure require a dosing solution that adapts in real time. Grundfos SMART Digital DosingTM pumps with FCM continuously monitor flow and pressure, automatically adjusting dosing to ensure consistent and optimal chemical delivery. This results in:
- Fewer clean-in-place cycles
- Longer membrane lifespan
- Reduced chemical consumption
