Koi Pond Filter systems - K+ Advanced Bead Filters

Introduction to the principle of K+ Advanced bead filtration

 

K+ Advanced bead filters are closed (pressure) vessels filled with K1+ bio media. This media floats and therefore provide a means of mechanical filtration and the enormous surface area provides the biological filtration.

 

Mechanical filtration: the media floats in a closed vessel and are packed very close to each other. The pressure of the pump makes the water flow upward through the media. The small dirt particles will stick in the media. The longer the filter is active, the more bio film will build up on the media and therefore smaller particles can be filtered.

 

Biological filtration: the specific surface of the media is about 950 sq. metres per cu. metre, so the bio film layer around the beads is the home for the nitrifying bacteria (the biomass) that convert ammonia into nitrite and nitrite into harmless nitrate.

 

 EA K+ Advanced bead Filters

 

 

The Microbead filters have a strong quality polypropylene vessel and as standard equipped with:

•  A drain valve to remove the sludge from the bottom of the EA K+ Advanced beadfilter
•  A 6 way multiport valve
•  A very reliable blower!

 

The EA K+ Advanced bead filter is now available in 4 sizes for ponds up to 4000, 8000, 12000 and 20000 Gallons. Equipped with a large clear lid for easy access.

 

•  All EA K+ Advanced bead models are standard equipped with a 1.5" or 2” multi-port valve, a transparent access cap and a powerful blower.
•  EA K+ Advanced bead are constructed from high quality polypropylene and are completely save for your fish.
•  The EA K+ Advanced bead comes with a warranty period of 2 years.

 THE MULTIPORT VALVE

 

Filter: water enters the EA K+ Advanced bead filter and goes upward through the beads and exits out of the vessel via the top spray bar to return to the pond.

 

Recirculate: : With the “RECIRCULATE” feature you can bypass your EA K+ Advanced bead filter and the water will flow from pond to pump to multiport valve and back to pond.

 

Waste:  This position allows the water to bypass the EA K+ Advanced bead filter and go directly to waste, such as when you are performing a backwash cycle. You can also use the waste setting to vacuum out your pond without the garbage going into your filter, it bypasses the EA K+ Advanced bead filter via the multiport valve and flows to waste.

 

Rinse:  The first time we use the RINSE feature to wash the beads with the blower this forces large amounts of air into the vessel and since air rises in water, the beads are broken apart by this action, making a thorough backwash easy to accomplish. After the backwash function we use the RINSE feature again but now with water instead of air. It is impossible to get every little bit of debris out of a filter and this causes these minute particles to exit in the waste line instead of going back into the pond.

 

Backwash: In this position we let the pump run until the water in the sight glass is clear (normally one to two minutes) The water enters the filter from the top spray bar (C) and exits the vessel at (A) and goes to waste.

Backwash Instructions

 1. With the pump running open the valve to the sludge drain. Keep it open for 15-20 seconds, and then shut it. This will purge the large solids that have made it into the EA K+ Advanced bead filter and settled out in the bottom of the tank to waste. It is very important to remove these solids from the system for overall water quality and more efficient filter operation. *IMPORTANT* Do not open the sludge drain valve with the pump off, as you may loose beads to waste if water is allowed to drain out this valve.

 

 2 Turn off pump.

 

 3. Move multiport valve to rinse. Air will go out of the EA K+ Advanced bead filter to waste and a small amount of water when blower is activated.

 

 4. Activate blower unit for 1-2 minutes. During this time the beads and debris is dispersed throughout the interior of the EA K+ Advanced bead filter. This breaks up all trapped particles in the filter allowing the debris to be easily backwashed out to waste.

 

 5. Move multiport valve to backwash mode. Turn pump on and run until backwash water is clear. Turn pump off.

 

 6. Move multiport valve to rinse feature. Turn pump on and run until water is clear. This takes any leftover debris that would have gone back into the pond and sends it to waste instead of sending a grunge cloud of debris back into the pond. Turn off pump.

 

 7 Move multiport valve back to EA K+ Advanced bead filter position and restart pump. You’re done. After you become familiar with the backwash process you can accomplish the backwash cycle completely in about 4 or 5 minutes. Every pond is different; however most people find that backwashing needs to be done once or twice a week.
