K1 Moving Bed Technology

Moving bed media has many advangates over traditional static bed filters including a huge surface area which is always exposed to maximum oxygen and food for the bacteria, self cleaning media as it tumbles, and the world famous protected surface area, enabling bacteria and higher organisms to dwell in their preferred location inside the media, exposed to oxygen and food, but safe from harmful cleaning practices.

Over the last twenty years there has been a wholesale shift over to moving bed technology in pond filters, and Evolution Aqua were the pioneers. No one has much experience or has carried out as much research and development into this important area of biological filtration as Evolution Aqua. Nexus and Eazy Pod use K1 and K1 Micro filter media exclusively, and the filters and filter media are all designed and manufactured in the UK.

Introducing the new Tempest from Evolution Aqua. The Tempest filter is an innovative polishing system for ponds that will help to deliver crystal clear, healthy water. Designed to be used in conjunction with any filtration system, the Tempest offers additional mechanical and biological filtration. The Tempest filter can also be used on quarantine systems or as a standalone filter on smaller ponds.

The Tempest filter is easy to install and is simple and quick to clean, by way of a unique, patent pending air syphon design. During the cleaning process, air is drawn into the filter as it empties which causes the water to agitate, effectively cleaning the K+Media.

Using Evolution Aqua’s K+Media as the filter media, particles down to one micron can be filtered.

New advanced filtration media

Plastic media, for use in biological pond filters – specifically in moving bed bio reactors, was pioneered by Evolution Aqua, some 20 years ago. In recent years, other plastic media have come onto the market, usually with the aim of trying to get more and more surface area. However, one drawback to using plastic media has always been the time it takes to establish a stable biofilm – essential for good filtration.

After many years of research, Evolution Aqua have now developed a new media that not only gives class leading surface area, but also overcomes the problem of long maturation times.

Class leading surface area

K+Mediais designed and manufactured in the UK by Evolution Aqua. This advanced media, with its innovative design, and class leading surface area provides enhanced biological and mechanical filtration.

As Evolution Aqua extrude K+Media, Minerals and Enzymes are added to the raw material. The result of this process, unique to Evolution Aqua, is a filtration media that not only outperforms most of its competitors due to its large protected surface area, but also answers the problem of how to speed up the time taken to mature your filter.

Minerals added for faster filter maturation

During the extrusion process, Evolution Aqua add a range of minerals, along with magnesium, calcium, enzymes and salt to the raw material that is used to manufacture K+Media. The result means that K+Media will mature much faster than many other types of media.

– The addition of these minerals creates a rough surface on the media. This textured surface has a microscopic honeycomb of peaks and craters that allow waste particles to collect, and nitrifying bacteria to form.

– The minerals act as a food source for the bacteria, helping the bacteria to develop and multiply at a faster rate, further improving maturation times.

– Calcium alone has proven advantages for developing and maintaining effective bio-films.

– The enzymes that are added also help to make the media “sticky” so waste particles can adhere to media easier.

– Salt is added during the extrusion process, which is dissolved during the cooling process, leaving a rough surface on which bio-film can easily adhere.

Increased surface area

With a new shape and profile, K+Media has also been designed to have an increased and class leading surface area, meaning an overall surface area of 1,350m² per m³. More importantly for biological filtration, the protected surface area of K+Media is 1,025m² per m³. This allows a stable bio-film to form and remain intact when used in moving bed biological filtration, as in the new Nexus+.

Stable bio-film development

The shape of K+Media optimises the amount of “quiet zones” within the media where a stable bio-film can develop. Whilst K+Media keeps the integral profile of K1 Media at its core, there is an extra layer of cells and fins around the outside of each piece that enable microscopic organisms such as Rotifers and Vorticella to thrive. This is an additional benefit as competitor media do not have such “quiet zones” that would allow these higher lifeforms of filter feeders to develop. The bacteria and organisms that form within the bio-film ensure the media delivers optimum levels of biological filtration in the moving bed, which has been proven filtration technology for many years in the fishkeeping hobby.

Use with PURE Pond products

Evolution Aqua also recommend using K+Media in combination with the PURE Pond and PURE+ Filter Start Gel to boost bacteria levels which in turn will stick to the media and speed up the maturation process even more.

Best-in-Class Filtration Media

The benefits of using K+Media have been well documented since its launch in 2019, including its ability to filter particles down to one micro. The design and profile of the media helps to improve flow, its vast protected surface area of 1,025m2 per m3, or the total area of 5x tennis courts, maintains stable bio-films and its unique manufacturing process where minerals and enzymes are added during the extrusion process, ensure K+Media matures faster than any other type of filtration media. Evolution Aqua’s filter media has also been independently tested to verify its performance by IFTS and Cranfield University. Read more »

How K+Advanced Filters work?

Water is pumped into the filter from the pond, through the multi-port valve where the internal pipework directs the water to the bottom laterals.

As the water flows upwards inside the K+Advanced Filter, dirt, debris and waste are trapped within the mass of K+Media that floats at the top of the filter. The vast protected surface area provided by K+Media also provides a home for beneficial bacteria, delivering mechanical and biological filtration.

The filtered water flows back through the laterals and pipework at the top of the filter, through the multi-port valve and back down the return line into the pond.

The K+Advanced Filter, is incredibly easy to clean by simply moving the handle on the multi-port valve into the corresponding positions to perform a backwash and rinse which flushes out the waste trapped inside.

How to install K+Advanced Filters?

The K+Advanced Filter can be installed as shown if you are planning to use a pre-filter such as the Evolution Aqua Cetus Sieve. If you are not planning to use a pre-filter we highly recommend that you fit a strainer basket to the pump.This will prevent leaves, string algae etc. from entering the filter and pump.

*It is recommended that all pipework on the pump side (from the pump to the filter and back to the pond) is installed on 2” pipe. Please note on the K+Advanced Filter 20 you will have to reduce your pipe down to 1½” to connect to the multiport valve. This will ensure that your pump is working at its maximum flow.

Do not operate the multiport valve with the circulating pump switched on. The air blower ball valve must be closed when the circulating pump is running.
