Partial flow filtration is used where there is a requirement for continuous flow, also during filter cleaning. Efficient removal of dirt and magnetic particles from the liquid reduces the number of breakdowns in the system and increases the life of measuring equipment, heat exchangers, pumps, valves and other components significantly.
In partial flow filtration, 5-15% of the total flow is led out of the system and pumped through the magnetic/bag filter, and is then led back to the system –cleaned of sludge and magnetite. As the partial flow filter is not located in the main circuit, the flow through the filter can be interrupted and the filter cleaned without interrupting the main flow.
Continuous reduction of the sludge content reduces sedimentation in heat exchangers, pipes and other components, helping to keep heat transmission performance at a maximum and reducing corrosion in the system. An error indication in mechanical measuring equipment and errors in connection with inductive measuring is also minimised, which is why it is possible to achieve more reliable energy consumption measurements.
The magnetic bars in the filter are located in conducting pipes which lead the liquid through a magnetic field generated by magnets with changing polarity. This induces a field around even the smallest particles and so provides efficient retention of particles of less than 1 micron. The filter will actively retain ferromagnetic particles and some iron oxides of the Fe3O4, g-Fe2O4, d-Fe2O3type and other mixed oxides of Fe3O4, where the spinel structure FeO is substituted by other oxides, e.g. CoO, MnO, NiO, ZnO, Cr2O3.
Non-magnetic particles are retained efficiently in the filter bag. (See also data sheet for filter bags).
