Bag filter
Bag filters are ideal for filtration jobs with heavy demands on flow rates and space. They are typically used for filtration of both boiler and cooling water, circulation water in district heating plants, rinse water and process baths in the surface treatment industry and in the electronics industry.
The bag filters have a robust design, which makes them suitable for both cold, hot, acid and basic liquids. They are easy to install and maintain and have no rinse water consumption.
Pore size 1 to 800 micron
For filtering solids and particles from liquids. Available in either nominel or absolute mesh sizes.
Pore size 10 to 100 micron
Filtration of oil emulsions, volatile oils or organic solvents by a combination of mechanical filtration and absorption.
Bag lining with metal fibers
Filter bags designed to prevent bacterial and algae growth in circulating systems. Also for filtration of pyrogenics.
Multitude of filter media
Filter bags well suited for chemical filtration where the water flow is high compared to the amount of matter to be filtered out. The filter media is replaced when it is used up and no backwashing is needed.
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.
The bag filters type EF are made for cold water (below 35°C). The filter houses are made of either PVC or steel coated with corrosion-resistant, high-density polypropylene. The support screen is normally of PVC. The EF 5 module is available in several different materials for special applications.
The bag filters type EFG are suited for filtration of hot water with temperatures up to 100°C. The filter house is made of steel. The modules can be supplied painted outside and untreated inside. They are also available in hot-galvanized steel and stainless steel. The filter can be supplied with a built-in magnet.
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.
