Water treatment

Fundamentals

Scale in the water pipe systems poses a serious technical problem for water supply and heating systems in households and industry. Calcium deposits (calcification, scale) generate heavy cost for the rehabilitation of water pipes and heating installations and are responsible for energy loss.

Consequences of sediments and corrosion

• Cooling systems / cooling towers must undergo chemical treatment and cleaning; heavy operation in terms of cost and cleaning time
• Temperature adjusting systems and tubular exchangers must be chemically cleaned at frequent intervals or, in the case of plate exchangers, the plates must be replaced regularly
• Vacuum and centrifugal pumps scale, and the deposits cause significant decrease in lifetime.
• Maintenance intervals, chemical quantification, repairs and downtime generate heavy cost, as much in terms of equipment as of maintenance and shutdown

AQUABION operating principles

The operation of AQUABION rests on the galvanic principle of a consumable zinc anode which wears out when there is voltage difference (0.70-1Volt) between the zinc anode and the metal body of AQUABION.
Depending on the water parameters, the galvanic element generates a difference in potential on the anode surface which causes agglomeration of the substances contained in the water around the released zinc ions (crystallization core).
The agglomerate responsible for the hardening of the water at the same time favours the crystal growth.
The result is that there are then more particles in the water which aggregate to the other released products.
These particles provide a larger surface area for the mechanical erosion of the inlay and the released particles are discharged with the water flow.
The calcite is then transformed into aragonite, and in the pipe system; the tendency to agglomerates adhesion is significantly reduced.

Mode of action of AQUABION:

The body of the AQUABION device is fixed in the pipe system or before a machine to protect in accordance with the requirements of the cross section and equipment and with the manufacturer's specifications.  
The main part of AQUABION is a consumable zinc anode of high purity. The anode is set inside the brass part between two stainless steel whirl producing elements. While the release of zinc ions occurs in a controlled manner by laminar flows, the elements causing whirls cause turbulent discharges in the AQUABION. The transfer of zinc ions is accelerated and the efficiency of the mechanism of protection is significantly increased. Water is divided into layers during the time of crossing the AQUABION, and thus comes in an optimal way into contact with the zinc anode.

Between the brass body and the zinc anode a difference of potential is created, which engenders electrolysis and causes the release of zinc ions. In this way, the pipe system is protected against corrosion phenomena such as pit corrosion or trough-like corrosion.

In AQUABION technology, we grant much importance to zinc ions: they cause a change in the crystal structure of calcium carbonate (sediment), thus preventing pipe calcification downstream of the heating elements and frames.
