Typical Pump Fed Filter Systems |
|
There are two main types of filtration systems, Pump fed and Gravity fed (two pump fed examples below, gravity fed on page 3). The difference between the two is: In a pump fed system the water is sucked from the pond and pumped to the filter. After filtration it spills back into the pond (possibly via a waterfall) thereby completing the cycle. In the pump fed system a submersible pump with a pre-filter may be placed in the pond (near the bottom) to suck out water. Alternativley a surface mounted pump could be used by installing pipework to its suction side, drawing water via a pre-filter in the pond and then pumping up to the filter. |

Filter System Identification Key |
|
|
|
1. Pre-filter Used to extend pump maintenance intervals buy preventing,
debris, newts, frogs etc. being sucked into the pump |
|
2. Submersible
pump. Sucks water from the pond and pumps it through the
UV to the filter. |
|
3. Flexible
Pipe. Routes the water from the pump to the UV. |
|
4. UV
Algae Master. For the control of green water algae. |
|
5. Magnetic
venturi. Oxygenates the water and helps to prevent limescale
and blanket weed. |
|
6. Pump fed
filter. For mechanical and biological filtration. To colonise
bacteria (for biological filtration), removes waste and improves
water quality. |
|
7. Filter
return. Return flow back to pond. Could be via a waterfall
or other water feature. |
|
8. Water
level of pond. |
|
9. Vacuum
pipework. Necessary on installations when larger surface
pumps are fitted. Soft and low grade pipe could collapse
due to the strong vacuum produced by these pumps. |
|
10. Surface
pump. Normally installed reasonably close to the pond but
not submersed or in any position where flooding is possible.
These pumps usually pump more water at a greater pressure
and tend to be more efficient. |
|
11. Sump
bottom drain installed at the lowest part of the pond where
fish waste etc. would normally fall and accumulate. |
