Methods for filtering pond water
If we want to strain with a filter that uses different filter materials in our pond water, we can rely upon a number of filter processes. Or better yet, we can combine several filtering methods together in line to purify the pond water.
Thus, it can be distinguished for
– For filtering
– mechanical filtration
– biological filtration
Any good filter would be utilized with these three standard filtering methods.
– chemical filtration
These bid methods can further extend the standard filtering.
For Filtering is also a form of mechanical filtration.
But we can see this quite strange because filtering has rather traditional multiform filters (multi chambers) to actually filter.
There are two major types of filters: the vortex (whirlpool filter) and the sieve.
For Filtering is great purpose to relieve the most dirt. A filter is always the first item in a filtering process, but you could have guessed at the name.
A filter is not really necessary but highly recommended.
It is namely the maintenance of the actual
filter simpler because the pre-filter collects most dirt, all before the pond water passes through the filter.
The filter is intended to absorb most organic waste especially when the design has also been taken into an account that can possibly be used for maintenance.
Filters that are not preceded by a pre-filter will have more dirt to be processed and also in the different mechanical filter materials such as brushes and mousses. By then, it will need to be flushed.
The biological part of the biological filter is what the materials have to deal with, as a filter. Less dirt is provided rightly so, because in the first place, it is the biological part of the housing of the beneficial bacteria and it does not absorb dirt because before, we have mechanical filtration.
Mechanical filtering aims to filter before the biological filter portion is reached. This test will be used as filter materials that have been developed, in order to stop the water flowing in the biological filter section. Brushes are the best known materials in suspending dirt as much as possible.
Many filters are also provided in their first chamber of the filter material especially, when there is no pre-filter. In mechanical filtering, materials are also used with a finer texture or also called as mousses.
But then, these are situated rather fully back of the filter, just before the water flows back into the pond.
They serve as a final fine filtering item for the smallest suspended dirt.
Next is the sand filter. Sand filters are the ones that wash water from the smallest dirt.
The sand filter is then considered to be the place of the last links in the filtering process. Sand filters are not really a necessity, but can be used if you really want to get rid of pond water’s every dirt particle.
The name biological filtration is slightly a misleading; for it is not actually the purpose of biological filter media to filter dirt from the water. Before the existence of filters and mechanical filtration,
biological filtration before has an enormous importance. Useful bacteria, harmful substances from feces, convert decaying organic material in less hazardous products, house on the biological filter media do their work here. Biological filter materials are being developed to accommodate a large colony of bacteria on a small surface.
Good living conditions for the bacteria questions include oxygen-rich environment. You probably already know that highly contaminated biological filter materials cannot meet this condition. Good living
conditions, including normal load biological filter material for the bacteria represents a good biological balance without algae and other pond problems.
Upon filtration, a chemical substance is usually added to the water which reacts with the other substances contained in the water. And with this reaction, are pollutants become less harmful substances.
Furthermore, ozone is an example of a chemical filtration.
It is a property of a chemical filtering that is not reversible.
Adsorption is a filtering process in which a soluble substance is removed by means of a solid material
from the water.
Some examples of absorptions are activated carbon and zeolite.
These substances adsorb
other elements from the water.
The filter methods discussed here are related to filtration systems that you can find in the pond business.
It is therefore an artificially created filter.
Other types of pond (swimming pond, marsh pond) or ornamental ponds with lower fish population will
not be provided if they are with a purchased filter that often provide some filtering, while we think of
wetland areas (plant filters substrate, lava stones, …) but that’s another story.
Schematically, it has a well thought filtering (from front to back) on the following filter methods.
– (Optional) Pre-filter (vortex, sieve)
– mechanical filtration
– biological filtration
– fine mechanical filtration (mousses, sand filter)
In addition to this performance, a filter with additional other filter elements can be further developed as an ozone plant, trickling filter, skimmer, etc.
The future of filtering
More and more are abandoning traditional multi-room filters and just go and build filters which are more compact, but the basic principles of the standard filtration (filter, mechanical, biological) is not affected.
While there are always newer methods come to market to both mechanical and biological filtration,
anything can happen.
