As a prefilter or partial flow filter, a bag filter can serve many purposes. Here are some examples of the applications that can benefit from mechanical filtration.
The magnetic insert is efficient for capturing small magnetic particles, typically not retained by a filter bag.
A partial stream filtration using magnets is particularly useful for circulating water, e.g. district heating plants, where magnetite naturally forms in the circuit water.
The top fits all existing EUROWATER bag filters, making an upgrade easy and affordable compared to changing the entire unit.
The Danish district heating company Hvide Sande Fjernvarme, had a high level of iron in the feedwater. Production manager, Martin Kristensen, explains:
"We had to do something about the iron content in the water, because it was above the recommendations of the Danish District Heating Association of 100 µg / L. We tried a 1 micron filter in a partial stream plant with two bag filters and a magnetic insert. It seemed to work!"
Reduction of iron in the district heating system, is part of asset management. Risk of corrosion in boilers, valves, fittings, installations, and underground piping is reduced significantly.
Our product range comprises a wide number of standard plants, all engineered and manufactured in-house. The starting point is our modular-built standard system ensuring high flexibility, high operational reliability, and short delivery time. Each solution can be customized and built according to the specific application needs by carefully combining materials, instrumentation, and control systems.
A bag filter consists of a filter house with cover and a support screen for the replaceable filter bag. The filter house is available with different surface material on the inside and outside according to filtration task.
The bag filters are also available as frame-mounted units
with optional pump and with two or more bag filters for higher flow rates.
Filter bags can be combined in series to obtain a high flow rate. The photo shows an installation with 10 bag filters type EFG7 at a district heating company in Germany.
