Johnson wire wound filter element of the geothermal tail water recharge equipment

1.Supporting Tubes of the Johnson wire wound filter element of the geothermal tail water recharge equipment

 Construction Drawing

If the slot tubes are used as a carrier for another filter medium for example textile. The surface profile can be:

1. reversed triangular

2. round

3. diamond shaped

In case of round wire the support tubes can be welded with 1, 2 or 3 wires next to each other.

2.Advantages of the Johnson wire wound filter element of the geothermal tail water recharge equipment

Compared with conventional support elements ( such as perforated tubes, wire mesh, ....) , support elements have following advantages:

1. a smaller contact between the support tube and the filter media there is more active filter area, which creates a larger active filter media and a smaller pressure drop. Thorough cleaning by back flushing possible.

2. a strong mechanical construction

3. large open area

4. easy to clean (back flushing)

3.The construction of a Johnson wire wound filter element of the geothermal tail water recharge equipment is described as follows:

surface wire / support wire x number of support wires.
Example: 0,8/2 x 18
This means that the profile wire is Ø 0.8. The support wire is Ø 2 and there are 18 support wires, equally spaced over 360°.
