Modern district heating production typically represents a massive capital investment,
which can result in unnecessary value loss, if the system water treatment is not functioning optimally:
- Scale formation
This is a well-known problem in district heating plants. Whether the deposits are caused by corrosion products or the ingress of raw water, scaling will lead to increased energy consumption, a risk of corrosion, problems with clogged system components, and a risk of microbiological growth.
- Corrosion
Corrosion in district heating systems can incur major costs for the district heating plant. In the short term, pitting corrosion in vital components at the plant or among consumers can cause operational disruptions and expenses. Over the long term, as the distribution network must remain operational, even slightly elevated corrosion rates will ultimately hit the plant hard financially.
- Microbiological growth
District heating providers' focus on energy efficiency means that system temperatures are generally on a downward trend. Lower temperatures increase the risk of microbiological growth, resulting in biologically induced corrosion and flow issues.
- Sludge accumulation
Accumulation tanks are a particularly vulnerable component in modern district heating plants. Sludge formation is an ever-present risk, and low water velocities increase the risk of corrosion and microbiological growth.
It is therefore crucial that the water in the district heating system is of the correct quality.
Guldager AdditiveCare – District Heating Systems
Guldager AdditiveCare is a comprehensive water treatment solution for district heating systems, ensuring that daily plant operations and production are safeguarded against operational disruptions – which also benefits long-term investments.
The AdditiveCare program includes a series of water treatment additives developed specifically to address the water treatment challenges faced by district heating operators:
- Oxygen scavengers for corrosion protection and passivation promotion
- Scale inhibitors to prevent scaling and energy loss caused by raw water ingress
- Sludge dispersants to protect against the fouling of heat exchangers and sludge accumulation in storage tanks
- Products for the removal of existing deposits during normal operation
- Biocides for controlling bacterial growth
You will always begin with an initial, thorough review of your district heating plant so that all operational aspects and issues are mapped out – both technically and economically.
The technologies in the AdditiveCare program are combined with Guldager's extensive range of water treatment plants, dosing and control equipment, analysis and laboratory services, as well as our comprehensive service portfolio.
