Challenge

Even if the pipes appear intact from the outside, the inside may already be on the brink of disaster.

Because drinking water quality differs regionally, the corrosion rate in every system is different. A high percentage of chlorides and oxygen in drinking water increases the likelihood of pitting corrosion and leaks can occur within a very short time, causing serious water damage.

In addition, the issue of microbial growth in closed systems is often underestimated. Dead algae or bacteria and their metabolic products cause mucous coatings. In addition, acid products can form, which lower the pH in the water and also cause pitting.

If incrustations and silting build up in the pipe the pipe diameter decreases. In combination with the resulting suspended particles the extinguishing effect of the system diminishes dramatically.

Solution

This can be avoided by mixing corrosion protection agent or microbiocide into the water via a dosing system.

A water analysis gives information on the optimal mixing concentration of the corrosion protection agent or microbiocide. This way, the proper functioning and calculated pipe diameter are retained.

The mixture into the water is preferably carried out into the pressure line between tank filling pump and pressure tank. Only one protective agent can be added per dosing system.

Corrosion or mucous coatings can be prevented with very simple means while your extinguishing system will remain fully operational.
