Professional beltfilter

Process
The water enters the filter through a pump fed construction. The water will run through the membrane (1) where waste parts, parasites, eggs, algae, plant remains, fish waste, etc. will be collected. On the membrane arises a so called 'filter cake' (accumulation of waste) which helps to improve the filtration again. During the increase of this filter cake less water can run through which increases the water level in the filter. The large hydrostatic pressure which pushes the water through the already polluted membrane ensure that the UltraFleece can sieve waste parts up to 20 micron. When the maximum water level has been reached, the level switch (7) will activate the conveyor-belt (5) underneath the membrane and the polluted membrane will be moved to the designated collection area (6).

A slightly increasing 30º angle guarantees the waste to remain on the membrane and not to be flushed away by the water. A new part of membrane is transported from the roll which enables it to let the optimal filtered water through. As the water falls through the membrane into the pump/bio-chamber it will also be enriched with oxygen. The water enters a lower bio chamber/pump chamber from where the water can go back to the pond or to the next biological filter. Because of the falling water bio rings in the bio chamber can be moved without the use of an extra air pump. Because of the thorough cleaning of the membrane the bio chamber does not require cleaning maintenance. The UltraFleece reduces the maintenance of your pond enormously and gives you an optimal water quality! As a result of this you can make great savings on the use of medication, water treatment supplements, large water changes and electricity! The usage of membrane rolls is highly dependant on factors like pond size, fish load, daily amount of food etc. An average usage for Koi ponds of 40.000 liter with 20 large Koi which get high protein food is between 8 and 15 rolls a year.

• Obvious improvement of the water quality.
• No cleaning maintenance, therefore no loss of bio-activity.
• Decreases the load on the biological filter.
• It is possible to use the membrane filter as a pre-filter in existing filter-systems.
• Manufactured from Polypropylene. Compact dimensions.
• Silent 24 volt motor which will only cost a few euro on electricity per year!
• The only maintenance is the replacement of the membrane roll.

BioBox
The PE bio-filterbox fits exactly underneath an UltraFleece, when placed in a 600 litre fish tank (SB930). The BioBox is equipped with three screens on which you can place (porous) biomedia, therefore producing a partial 'trickle-filter' effect from the section that is above the water surface plus a submerged filter.
