Remote monitoring of agricultural air scrubbers
Starting January 1, 2026, the Flemish government will require electronic monitoring for all agricultural air scrubbers and biofilters. These systems remove nitrogen from barn air.
To help livestock farmers comply with the new regulations, Liquisens and Crodeon have developed a high-quality, user-friendly retrofit solution in full compliance with VLAREM legislation.
Retrofit monitoring for agricultural air scrubbers
The solution is easy to install on existing air purification systems and ensures continuous monitoring of all mandatory parameters, fully compliant with VLAREM. Thanks to this collaboration, data is automatically transmitted to the Flemish government’s ARMOS platform.
“The Flemish government wants better insight into how existing agricultural air scrubbers operate,” says Steven De Schrijver, CTO at Liquisens. “Our retrofit solution offers farmers an affordable way to comply with the rules without having to replace their entire air purification system or control cabinet.”
A smart retrofit solution powered by Reporter
Liquisens’ monitoring solution combines sensors with our Reporter, a plug & play IoT module that transmits data in real time via the mobile network (GSM). This means there’s no need for Wi-Fi or Ethernet, making it easy to electronically monitor agricultural air scrubbers in poultry and pig barns.
The required parameters of the scrubber water (pH, conductivity, pressure drop, and flow rate) are measured, stored, and analysed every hour. In case of deviations, the farmer immediately receives an alert via WhatsApp or email. This allows for quick action, while a complete logbook is automatically stored locally for up to five years.
With an installation cost starting at €12,500 and a VLIF subsidy of up to €14,000, this affordable retrofit solution is a smart, future-oriented choice for every agricultural air scrubber in livestock farming.
Ready for tomorrow’s regulations
Many farmers face uncertainty regarding permits and possible additional requirements from 2030 onward, when stricter standards for low-emission barns will come into effect. Full clarity about these future requirements is not yet available. The retrofit solution from Liquisens and Crodeon therefore provides a practical interim step: it enables farmers to already meet the VLAREM requirements today, without major or unnecessary investments.
Because the technology can be applied to any agricultural air scrubber, companies can keep their existing infrastructure while still fully complying with regulations. The solution is also available for installation on other air purification systems, such as biofilters.
From measuring to improving
Liquisens is collaborating with Ghent University (UGent) and ILVO to use real-time data for research into the optimisation of agricultural air scrubbers. This partnership will lead to a Baekeland mandate in 2026, focused on further improving air purification systems in livestock farming.
“We don’t just want to measure, we want to improve,” says De Schrijver. “With data, we can provide targeted advice to both farmers and policymakers.”
Liquisens & Crodeon
Liquisens specialises in smart solutions for real-time water quality monitoring, which also forms the basis of air purification.
Crodeon develops Reporter, a flexible module for applications such as remote CO2 monitoring in pig barns, ammonia measurements, and lux measurements in livestock facilities. Together, we offer farmers a reliable and affordable way to electronically monitor their agricultural air scrubbers.
Liquisens handles installation and remains the main point of contact for customers. Visit www.luchtwasmonitor.be for more information or to request a site visit and personalised proposal.
