Protein Skimmers  from Estrad:

The EstroClear

protein skimmers not only ensure clear clean pond water, but they also remove any surplus proteins, carbohydrates and other organic compounds. After activation they work directly and they deliver large volumes of extra oxygen into the water. Froth on the surface of your pond is now history and you can enjoy clear water the whole year round. A primary requirement for strong healthy fish.

The principle.

By means of a Venturi, an intense mixture of air and water is created which is eventually supplemented with ozone. This mixture is introduced by means of rotation into the bottom of the skimmer. The air bubbles rise upwards and in doing so they take any floating waste and organic particles with them. Protein compounds such as cellulose, bacteria algae and parasites attach themselves to the bubbles.

This waste froth caused by the proteins is now removed from the water by a clever construction of small tubes. The waste water goes to the sewers or can be collected in a bucket and used to treat your garden to a nitrate rich meal. Your fish are now fertilizing your plants and flowers instead of filling your pond with algae.
A primary requirement for strong healthy fish.  The protein skimmer works even more efficiently if you feed ozone in via the Venturi.  This turn the apparatus into a protein skimmer/ozone reactor. A pH higher than 8.2 causes very poisonous ammonia to be converted into nitrate almost immediately. The nitrogen bubbles freely out of the water and even nitrite is no longer created. If the pH is lower than 8.2 then ammonia is converted into nitrite. This nitrite can now be converted immediately into nitrate by means of the super oxygen O3. Numerous other compounds such as iron oxide, manganese and yellow dyes will be removed also.
Venturi.

A Venturi is a small apparatus that utilizes pressure differences to add large amounts of air or ozone to the water. This is the quickest way to achieve an oxygen rich mixture, but the process demands a strong high pressure pump. Low pressure pumps are not suitable.

A normal pump with a water head of 15 feet or more works perfectly and you can increase the effect by connecting an extra air pump to the auxiliary inlet. This method can be used if your present pump has insufficient pressure to work a Venturi.
Winter use.

In contrast with many other filter systems, you can use the EstroClear protein skimmer during the winter. In fact this is recommended. The system can function to keep your pond ice free. To achieve this you have to install the water outlet in a ring around the filter (an optional extra).

New Ozone Reactor

This is the New Estrad Ozone Reactor and has been designed to work only on an Ozone System - it has not been designed to work just as a Protein Skimmer ...  Using this Reactor the ozone waste is completely sterilized and burnt. This way the decomposition process that uses large amounts of oxygen is prevented. During this process, nitrite is produced, resulting in a lower nitrate content in your pond water.

The illustration on the left is the New Estrad Ozone Generator

This model is suitable for ponds of up to 180 cubic feet and is suitable for a high pump capacity, whilst smaller pumps can be used via a water switch.

The long water contact is made possible through the blue tube on the right hand side where the water is ventilated for a second time and the last remaining ozone is removed.

The Venturi can be seen mounted on the top and this is adjusted to provide the best flow through the system and maximum Ozone burn off

This occurs because a certain amount of basic waste material is necessary to ensure maximum adhesion in the skimmer housing. After this "running in period" it produces clear water.

 


The EstroClear has been especially designed to work as an Ozone Reactor on the Estrad Ozone Systems and is extremely efficient and it has a very high performance.

Pump size required 8000/12000 liter/hr
