SuperBead
The SuperBead combines fine mechanical filtration with biological filtration. The SuperBead is used for koi and swimming ponds, as well as swimming pools. The filter features a different rinsing process than ordinary Beadfilter systems and sand filters.
The SuperBead filter removes with just one passage through the filter 100% of particles larger than 50 microns and 48% of particles between 5 and 10 microns.
The Beadfilter’s rinsing process
Link to the SuperBead Animation
Every Beadfilter features a rinsing process. The trapped dirt particles have to be removed from the filter. The SuperBead was specifically designed to accommodate this rinsing process in contrast to modified sand filters.
The SuperBead properties:
- steady flushing process: does not damage the bio-film
- energy-saving: suitable for low-pressure pumping
- simple: easy to understand and operate
- reliable: no electronic or wear-sensitive components
- little maintenance and a fast rinsing process
- easy to automate
- superior clarity: effectively removes solid particles
- stable bio-film
- suitable for sea water
Brief description of the operating principle
- following coarse pre-filtration, the water is pumped into the filter
- the beads rise to the top where they float
- the beads trap fine particles up to 5 microns
- biological filtration takes place on the surface of the beads
- the captured contaminants are removed during flushing
- the flushing has an easy automation option
The SuperBead’s hourglass shape ensures:
- steady water flow through the filter
- good distribution of water over the filter bed
- the flushing process
The SuperBead:
- uses little flushing water
- has high flows at low pressure
- has a high biological capacity
- has large connections
Pumps and energy-saving
One of the biggest advantages of the SuperBead filter compared to other sand or bead filters is the required pump pressure. With the SuperBead, it is possible to work with pumps that operate at low pressure, which is very energy-efficient. Examples of such pumps are the FlowFriend pumps. Unlike modified sand filters, which often need two to four times as much pump power to pump the same amount of water, the SuperBead filter is much more efficient.
Practice
A SuperBead filter requires a pre-filter system, such as the SuperSieve or a drum filter like the SuperDrum, unless it is used in an indoor pond. The SuperBead is easy to fit, both above and below water. Moreover, the SuperBead can easily be fitted further away from the pond, provided the pipework has suitable dimensions. As the filter is a closed system, indoor fitting of the filter does not result in any moisture, odour or insect problems. Outdoor fitting is no problem as the SuperBead has no electrical components. Furthermore it can be used at seawater applications because all components are made of plastic.
Automating the SuperBead flushing is one of the best ways to guarantee good water quality. The filter is then flushed fully-automatically, for instance every day, so that contaminants are removed automatically every day. If necessary, a dirty-water pump can be connected that activates during flushing to suck the water from the SuperBead to the drain.
