Our Success Stories

Brussels Airport contacted us with a relatively specific request. They have mobile trucks responsible for de-icing aircraft wings in winter, on the tarmac. These trucks intervene just before takeoff to apply a product to the aircraft wings, because if they are covered in frost, the plane won't be able to take off. To remedy this problem, they use a mixture of water and alcohol (ethanol), similar to the winter windscreen washer fluid used for cars. The mixture of hot water and alcohol they use causes rapid clogging of the spray nozzles. They therefore imperatively need to use treated water to prevent limescale deposits. Trucks are filled in a large hangar near the runway, where 30,000-40,000-liter tanks hold ready-to-use mixes. Water, from a 2-inch pipe connected to the Zaventem network, is added first, then topped up with ethanol. Town water in this region being very calcareous (probably around 35°f), it is therefore necessary to treat it before it enters the tank. This prevents limescale build-up at the bottom of the tank and prevents clogging of the unit's holes when spraying.

If salt softeners are used, the system will constantly regenerate. In fact, regeneration of salt softeners is legally required once a week. However, between April and October, the deicers are not used, and the tanks remain inactive during this period. The problem lies in the fact that installing a softener classical would result in consumption excessive water without genuine use, due to the need to regenerate the system regularly. This is one of the reasons why SoluCalc have been installed : these systems don't need not of regeneration, avoiding thus wasting water. With regard to the interactions between ethanol and water after treatment with CO₂, it is important to specify that we only intervene on the pH of the water. Thus, there are no compatibility problems to report. The installation was carried out by Willems Techno, acting as a subcontractor for TCR, the company responsible for maintenance of the entire airport site. Currently, a SoluCalc of 2 inches is in place, equipped with six 10-kilogram bottles each.

At the request of Engie, responsible for the building's maintenance, we were approached several years ago (2018-2019). One of their employees, having discovered our CO₂ water treatment project on the internet, was very interested. They approached us to implement a pH management solution, essential to the hospital's specific needs, to ensure that the pH does not fall below a critical threshold and comply with medical requirements. At the time, we didn't yet have the right solution, which prompted us to step up our R&D efforts. This led to the design of a solution equipped with an automatic cut-off system, ensuring that the pH did not fall below the critical threshold.

We've developed SoluCalc Connect & Secure, which offers several very useful features: - You receive a notification when your bottle is almost empty. - You can turn on/off/pause (with timer) your SoluCalc remotely with automatic reset. - Monitor your water and CO₂ consumption. - Access to your history and real-time monitoring of your consumption, pH and water temperature. - Your pH safety, allows you to cut off injection if the pH drops below a configurable target value. For about two years now, they've had this high-performance system, which is equipped with a pH probe and a system for automatically cutting off CO₂ injection if the pH drops below 6.5. It was this success story that enabled us to bring the product to market. Thanks to the positive feedback and results obtained with the SoluCalc Secure prototype, equipped with the pH probe and automatic cut-off system, we were able to develop and market this innovative, safe solution.
