Water Treatment in Hospitals

In hospital settings, the sterilization of surgical instruments stands as a critical facet of quality assurance, necessitating strict adherence to regulatory standards. Stringent controls are imperative for both steam and water parameters to mitigate the risk of metal surface deposits and corrosion on surgical instruments.

To achieve compliance with these rigorous requirements, demineralized water emerges as a standard choice for sterilization purposes. Hospitals employ advanced water treatment systems to produce demineralized water, thereby ensuring the optimal efficacy of the sterilization process.

DIN EN 285 stipulates the following limit values for the boiler feed water:
Conductivity       ≤ 5 µS/cm
pH value:           5 – 7
Total hardness   ≤ 0.02 mmol/l
Salt content       ≤ 10 ppm
Phosphate         ≤ 0.5 ppm
Silicate (SiO2)   ≤ 1 ppm
Chloride            ≤ 2 ppm

Introducing Testomat® 808 SiO2 for Hospital Applications

In response to the critical need for a reliable and straightforward silicate measuring solution in hospital environments, Heyl Brothers presents the Testomat® 808 SiO2. This precision limit value measuring device is designed to accurately detect silicate levels within the 0.3 to 1.2 ppm range, ensuring meticulous silicate monitoring.

Silicate concentration fluctuations, often influenced by the EDI system's amperage, can lead to breakthroughs when the current is set too low, resulting in deposition and disruption in the ion exchange process. The Testomat® 808 SiO2 serves as an immediate alarm system for silicate breakthroughs, enabling prompt inspection and intervention.
