담수용 스키머 - Skimmers for Ponds/Freshwater Applications

우연히 검색하게된 담수용 스키머입니다.
물 관련해서는 그다지 경험이 없는지라 제 짧은 경험으로는 해수용 스키머와 무슨 차이가 있는지 알 수 없군요.

Jetskim이라는 제품은 이름에서 연상 되듯이 강력한 벤튜리 인젝터를 사용하여 스키밍하는 듯한데, 이 제품이 강력한 스키밍을 행한다 할지라도 여러가지 덩어리들이 문제시 되는 거북사육조에서 그 효용성이 어떠할지 궁금하기도 합니다.

물론 제 개인적인 선택은 프리필터입니다만...


그냥 이런 제품도 있으니 참고해 보시라고 링크 걸어 놓습니다.

Schuran Jetskim Freshwater 150 and 200

We Are Proud to now include these superb, and well made, Protein Skimmers into our vast range of Products, and would e pleased to be able to advise you on the correct equipment for your own particular application.

Jetskim Freshwater Skimmers improve water quality and make it possible to keep higher densities of fish than would be possible without a skimmer.

The Jetskim Freshwater range is suitable for aquaria from 500 litres to koi ponds up to 25000 litres.

These skimmers use a venturi injector system. As a result, waste products accumulate in the light foam that emerges from the top of the skimmer.

An ozone reactor for this skimmer is available on request.



Sander Freshwater Protein Skimmers
 

     

 Improved technology has made it possible to skim off harmful protein compounds from freshwater.

The Sander freshwater skimmers are specially developed and tested for koi ponds and other freshwater applications making them the ideal skimmer for your freshwater pond/tank.

These skimmers remove proteins before they are decomposed to toxic compounds, and turbidity and algae will also be removed.

Skimming is achieved by bubbles produced by airstones, not a venturi, and therefore requires a suitable air pump or compressor.
In combination with ozone, these freshwater skimmers will considerably increase water quality.

Protein skimming or foam fractionation is the process by which dissolved and particulate organic carbons are removed from a liquid, in this case the fish culture water, by adsorbing them onto the surface of fine bubbles rising in a closed contact column against a counter-current water flow.

The bubbles burst and form stable foam at the top of the water column and the accumulated organic wastes are discharged from the column along with the foam produced.

The removed substances are called "surfactants" because they are surface active or "charged"

Benefits of Protein Skimming include:-

Removal of suspended solids.
Removal of proteins and high molecular weight compounds.
Increased water clarity through removal of humic and phenolic compounds.
Increased oxygenation of the culture water.
pH stabilisation through removal of organic acids.

 
Performance is defendant on:

Salinity
Air to water ratio
Air bubble diameter
Column height
Air/water contact time
Use of ozone

Bubble size is the most important of these and within the control of the design of the protein skimmer.

An efficient air diffuser or venturi plays an important part in generating a swarm of bubbles that are as small as possible, ensuring maximum surface area for the adsorption of the organic compounds. Smaller bubbles also rise more slowly, allowing more contact time with the process water.

Generally it is difficult to generate a small enough bubble size in freshwater to achieve effective foam production (except in cases of very high organic loading) and therefore protein skimming is mainly only recommended for seawater or brackish applications where the salinity is more than 16 ppt. However, a number of freshwater skimmers are available for use in ponds.

Protein skimming is further enhanced by the application of ozone into the air mixture, which further oxidises and breaks down complex organic compounds as well as providing a degree of disinfection, depending on the quantity used.
