Biodrum Gravity Trickle

BIODRUM GRAVITY TRICKLE

After developing the Biodrum Rotator, MPF has developed another innovative design for the pond market. The Biodrum Gravity Trickle!

A combination of a drum filter as a pre-filter with a trickle/bakki shower filter behind it, which can be set up in gravity.

The unique concept of the Biodrum Gravity Trickle is the gravity setup. All trickle filters must be installed above water level, which is often an aesthetic issue.

The water flows onto the upper drip tray by means of a water level controller. As a result, the water is optimally distributed on the underlying material. This water level controller ensures that the water level remains constant regardless of the performance of the pond pump. This construction creates the best pre-filtration through the drum and the best biological cleaning through the trickle filters. The water breaks continuously and at high speed, which means that the oxygen uptake in the water is enormous. This leads to a continuous outgassing of ammonium and CO2. And so the Biodrum Gravity Trickle produces better water quality and healthy koi.

You can determine the biological media in the trickling section yourself. We prefer Crystal Bio. Crystal Bio consists of a glass substance. It has an exceptional porous structure made from lightweight ceramic. Due to its porous structure, Crystal Bio has an exceptionally large surface of approx. 18000 m2/m3 Crystal Bio itself is a stone-like material with KH buffer properties.

Advantages :
Better biological effect
Can be placed underwater
Quick start of biology
clear water
Stable bacterial culture
No more air pump needed
Very oxygen-rich type of filtering
Little to no upkeep
Can handle 2.5x as much feed as a moving bed

What is the best setup for my filter?

We always recommend setting up the filter in gravity. The filter is placed at water level and will then protrude approximately 11-14 cm above the water level. Due to the effect of gravity, your filter fills up with water. A pond pump moves the water from your filter back to the pond.

What is the capacity of a pump fed filter system?

If a pump-fed system is chosen, there are a number of things to consider. First, pump fed systems have less capacity. Take a loss of 30% into account. For example, a Biodrum 100 can handle a maximum of 50m3 per hour in gravity setup, and a pump-fed system a maximum of 35m3. The biochamber will also not be completely filled with water, so less biological material will be able to enter. Our advice is to always go for a gravity system.

If a difference is measured, the electronics will activate the flushing. During this flushing, the drive motor turns the drum filter and a high pressure pump from the nozzles (the mouthpiece) sprays the screen. The nozzles spray the water in from the outside of the drum to remove the dirt. This dirty water is collected on the inside of the drum filter by means of a gutter through which the water flows to the sewer. Once the water level is back at the correct level, the drum filter will flush for 20 seconds to ensure proper cleaning. After this, the pressure pump and drive motor will switch off and the electronics will continue its measurement until the next flush.

Our controls

Through years of testing and innovation, we have developed 2 types of controllers for our filters. The simple MPF controller electronics and the MPF Professsional Drum control with Siemens logo control.

MPF CONTROLLER

Standard supplied with each filter.

- The pond pump stops when the water level is too low and turns on again when the water level in the pond is raised again.
- Industrial electronics cabinet in a compact housing
- Provides automatic flushing
- Industrial Relay 16A
- Manual flushing by push button
- Digital display

Option:

MPF Professional Control with siemens logo controller.

This electronics with Siemens Logo 8 controller is a new generation logic module suitable for any customer requirement and is extremely reliable. So reliable that even the large water treatment plants work with Siemens! (surcharge €350,00)

The pond pump stops when the water level is too low and turns on again when the water level in the pond is raised again

- Provides automatic flushing
- You can read the data via internet
- Via an app you can control the Siemens Logo8
- Change flushes yourself if you want longer or shorter flushes
- A daily counter is integrated so you can read out the total number of flushes and daily flushes
- A signal is given when the drum has been in the dry run protection mode
- Possibility to flush your gutter by connecting an additional flushing pump
- Many possibilities to expand the drum to your liking
- 1 x per hour rinsing to prevent the fabric from drying out (winter mode)

Drum UV connections

Each MPF filter is equipped with one or two Drum UV inputs. This makes it easy to install an MPF Drum UV using a rubber coupling.
