PICKLING OF CORROSIVE AND MICROBIALLY CONTAMINATED HEATING AND COOLING DISTRIBUTION NETWORKS
for a trouble-free operation Filling water treatment is necessary and can prevent corrosion damage and microbial induced corrosion. For networks, where corrosion has been neglected for a long time, there may be a "point of no return". This means that filling water treatment is no longer possible within regular circulation and instead the pipe network must be cleaned from strong corrosive deposits and biofilms by means of strong chemicals. These strong corrosions, which are often combined with biological film formation, occur mainly in low temperature heating and cooling systems. In many cases the water has a relative optimal pH value of 8.5 or higher. Nevertheless, strong corrosion and biofilm formation occurs. So-called "acid clusters" play a major role here. On individual areas of the surface of the installed metal or plastics, there can be an extremely acidic pH value of less than 4.0. For this "chemical pickling" is the only reliable method of dissolving these acidic surface layers and remove the "acid clusters". The removal with chemicals and other biocides is usually only successful if all layers of corrosion are removed. In these cases, optimum success in the long term can only be guaranteed by a special chemical treatment. This process is called pickling. However, for this method the used materials need to be carefully examined and the chemicals adjusted accordingly. Alpenlandwater is a specialist company experienced in these procedures.

Prevention saves costs!
Especially the latest and most efficient technology has to be handled in the best possible way!
Drinking Water is not suitable for filling HVAC systems. Therefore, it is also unsuitable for filling combined heat and power as well as biogas facilities!
Unfortunately, many plant operators are unaware of the values recommended in accordance with technical standards and the type of treatment their filling water requires or are simply overwhelmed. Although regular tap water is cheap and available everywhere, it predominantly includes materials that swiftly cause considerable damage within complex and above all sensitive conjunctions of materials such as those found in most plumbing and heating systems. Corrosion and calcification cause more than half of all problems in modern heating systems. Clogged heat exchangers, pumps, and pipes as well as defective valves cause problems and stress for customers, specialist companies and manufacturers. The result can be prolonged production losses at which time good advice becomes expensive due to the closed circuits involved, which make rapid fault analyses extremely complex and costly. Avoid: > Warranty risks > Financial losses due to downtime

Standard-compliant raw material usage: avoid contamination to prevent high rehabilitation costs!
The HVAC system must be optimally prepared for filling. Dirt and impurities (foreign particles) are significant corrosion factors, which means that any introduction of impurities into the HVAC system must be avoided. Appropriate precautions must be taken as early as during the plant planning stage. Among other things, this is achieved by the use of clean and standard-compliant pipework materials (free of loose scale, rust, internal burrs and impurities), fittings and equipment (boilers, heat exchangers, radiators, convectors, expansion vessels, etc.) as well as by flawless production (with no weld beads, sealant or flux residues, burrs, swarf, etc.). It is necessary to clean all components of a heating system thoroughly prior to installation. |
