What is a fluidized media bed?

A fluidized bed consists of a fine hard media (i.e. white aluminum oxide or sand) that is partially suspended by a fluidizing gas. The gas is passed through the media from the bottom of the bed.

What is a fluid bed filter?

A fluidized bed filter is a container that hangs on the back of your fish tank. It can also be a cylinder or even a canister which can sit in a sump on the floor beside or under your fish tank. This will be connected to a pump to push water through the filter. These filters are actually known by many terms.

Is K1 filter media good?

When it comes to selecting an effective biological medium it doesn’t get much better than K1 media. This can be used as an affective method of trapping suspended solids in a filter without the risk of blockage. But it is when K1 is used as a mobile biological bed that it really comes into its own.

Is moving bed filter good?

Organic matter in the moving bed filter can smother the nitrifying bacteria, and it may even lead to the development of heterotrophic bacteria that grow much faster than nitrifying bacteria.

How does a fluidized bed filter work?

How Does a Fluidized Bed Filter Work? Fluidized bed filters provide biological filtration very similar to that provided by under gravel filters. Nitrifying bacteria colonies grow on the surface of the particles of sand in the bed, and process ammonia and Nitrite into Nitrate as the water passes through the filter.

How does a fluidized bed work?

Typically, pressurized gas or liquid enters the fluidised bed vessel through numerous holes via a plate known as a distributor plate, located at the bottom of the fluidised bed. The fluid flows upward through the bed, causing the solid particles to be suspended.

Which is better K1 or K1 Micro?

Not only does the 950m2 per m3 protected surface area help to improve nitrification, water quality and clarity, but K1 Micro can offer many more benefits when compared to standard K1 Media and beads. Key Features: Increased protection for the bio-film.

How long does it take for K1 Media to sink?

The cycle usually takes about 6 weeks, temperatures permitting, so you are getting there.

Why are fluidised beds used?

In fluidised beds, the contact of the solid particles with the fluidisation medium (a gas or a liquid) is greatly enhanced when compared to packed beds. This behavior in fluidised combustion beds enables good thermal transport inside the system and good heat transfer between the bed and its container.
