Hi,

last week we finished the renovation of our pond number D4 :D . This pond is the first in Indonesia with a rotary drum filter installed. The pond will not need any maintenance and it should provide superb water quality :D .

The technical data and main features are:
-27,5 tons water capacity (only 3,5 tons for the filter chambers :!: )
-3 bottom drains of 6 inch, 1 skimmer
-collector chamber to feed the drum filter (750 liter)
-rotary drum filter with a flow rate of max. 30 tons/hour
-300 liter Helix 14 Filter Media in a "moving bed" chamber with 2,2 tons (can handle 1,5kg of koi food / day, the amount can be doubled by
adding another 300 liter of Helix 14)
-pump chamber (750 liter) with 2 Tsurumi pumps (each 15 tons/h flow)
-500mg Ozone Generator in the collecting chamber for de-colouring the
water (the yellowish colour disappears when using Ozone)
-2 Yasunaga air pumps (LP 40)
-no cleaning of filter or filter media (cleaning is done automatically)
-automatic water refill (no weekly water changes)

Here are some photos from the setup and the filter:

Congratulation to you Svenni
I just visited your pond last week. That's a really good pond and nice place too, I'm enjoyed seeing your fish.
But, I have question how to the rotary drum filter working??
May you can explain to us? :wink: :wink:

Hi,

here is some more detailed explanation. I hope it is more easy to understand now :D :

The water enters the drum filter via the inlet on the left side. The water enters the inside of the drum which is covered with a 60micron screen. To leave the filter the water has to pass the screen and all particles (especially fish waste and organic matter) are remaining inside the drum:
http://www.koi-collection.com/Images/drumfilter/D4-drumfilterwdescr.jpg

When the waste accumulates inside the drum it cloggs the screen and less water will flow through the screen to the outside of the drum. The sensor on the back left (see picture) is set to a certain water level. When the water level outside of the drum falls below this set level the sensor will start the flushing process. During the flushing (cleaning) process the drum is turned by a gear motor and the spray nozzles on the top of the drum clean the screen with high pressure. The waste/dirt is directly flushed into the drain inside the drum. This drain is connected to a pipe that lets the water flow into a drain outside of the pond, i.e. the waste is directly flushed out of the pond water system and cannot dissolve and pollute the pond water. The screen is clean again and the water level outside the drum will rise again:
http://www.koi-collection.com/Images/drumfilter/D4-drumfilterinside2wdescr.jpg

http://www.koi-collection.com/Images/drumfilter/D4-sprayunitwdescr.jpg

The control unit is connected to the sensor in the filter and the jet pump that flushes the water through the spray nozzles. The duration of the flushing process can be adjusted on the relais (see picture). Usually the flushing process duration is between 4 to 8 seconds only:
http://www.koi-collection.com/Images/drumfilter/D4-controlunitwdescr.jpg

The mechanically clean water from the drum filter enters the Helix chamber and the bacteria there will break down the ammonium/ammoniak (as in any other filter system). Due to the fact that the waste is quckly taken out of the water the bio chmaber has much less workload because the harmful substances of the waste cannot disslove in the water :D .

If you have any further questions please let me know

Thanks for your explaination Svenni.
Know, I'm understand the working of rotary drum filter.
Is it guarantie cleaning your pond?
With this filter system no need another filter sytem again?
What about limited pond volume can handle with this rotary filter system?
I'm sorry for too much asking. :wink: :wink:

Hi,

there is no need for any additional filtering. If the setup of the pond is correct (enough water flow, i.e. pipe diameters big enough) it provides perfect water. The model I installed can handle a water flow of 30-35 tons per hour and we recommend it for ponds of up to 50 tons capacity. There are 4 different models which can be used for ponds up to 300 tons water capacity.

The main benefit of this filter is the fact that the waste is not remaining in the water (like in Vortexes or settlement chambers) and it cannot polute the water that much. The bio chamber has less workload and can easily reduce ammonium/ammoniak in the pond. Also it does not require regular backwash or cleaning and you can enjoy more time with your koi rather than cleaning the filter :lol:

Hi Sveni, I'm very impress with your rotary drum filter. This kind of system must be very costly. If I may ask, what sort of result do you expect from this new system? i.e, fish will grow faster than normal filter system? Or just to maintain good healthy water?

May I know the cost for this rotary drum filter for 4 each kind of filter system that you said? :wink:

Hi Pak,

yes, the system is not cheap (due to the filter, the rest is reasonable in price :D ) but the benefits are quite a few (especially when you have expensive koi swimming in your pond :wink: ). Regarding the results I expect a lot. With this system I can feed big amounts of food without spoiling the water. That should result in very good growth rates. Furthermore, in a good water quality the koi feel comfortable which makes them less vulnerable for deseases. Also the fact that the waste gets out of the water very quick will result in less "bacteria pressure" in the water. In our tropical region and the resulting high water temperatures bacteria have a perfect environment to multiply. That's good for a quick maturing of filter bacteria but it also helps growing the "bad" bacteria such as pseudomonas and aeromonas. Especially when there is a high amount of organic waste in the water it will be good "food" for the bacteria and bacterial infections can more easily occur. Therefore I expect less problems with bacterial infections (the ozone also helps a bit with the sterilization) because there is far less organic matter in the pond system. One of the main features remains the fact that we do not have to consider about the back wash/cleaning etc. anymore. Also water changes/refill is a matter of the past :D

@Hankoi:

Prices for the filters are:

TR1 compact: 30.000 liter/h flow rate => RP. 39.000.000,--
TR2: 50.000 liter/h flow rate => RP. 59.000.000,--
TR3: 100.000 liter/h flow rate => RP. 79.000.000,--
TR4: 200.000 liter/h flow rate => RP. 119.000.000,--

All equipment installed in our pond has a total price of approx. 47 jt. That includes TR1 compact filter (incl. control, pump and gear motor), 300liter Helix, automatic refill-valve, ozone generator with 500mg, LP60 Yasunaga pump, piping inside the chambers and air hose and stones. Pond/chamber construction and piping from the pond to the chambers is not included

Hi Sven,

Thanks for the features of this quite hi-tech filter, which is mainly a pressure filter for mechanical function with auto flush/back wash, reminding it to the Japanese one of Wakashimitsu and UK's Aquadyne. The last two filters' prices are even doubled/tripled than yours :cry:

What do you mean by "the benefits are quite a few" on your comments above?

Meantime as discussed, please let me see how it works when I return from holiday..

cheers

Hi Ricky,

I just checked the auquadyne website. These filters are bead filters using small pellets inside. The water has to pass these pellets which results in very good mechanical cleaning. Also bacteria will settle on the pellets and the biological cleaning will be done by the pellets as well. However there are some things you should consider. Bead filters usually request a mechanical "pre-filtering" like bow sieve or similar. Furthermore the inlet and outlet have small diameters and you need pumps with high power consumption to manage the requested flow rates. Furthermore the backwash usually has to be done manually by closing the crane to the pond, opening the crane to the drain and switch a crane on the filter to start the backwash. However it is true that this can be even done wearing a business suit :D .

I already discussed with my supplier about a new generation of bead filters that he developed. These filters are called "Swing-bead" filters and they can be operated with normal low energy pumps. The smallest filter will be called Swing-Bead economy and it will start at a selling price of approx. 16-17 million Rupiah (ex Jakarta). My supplier is willing to give me some units for display. I will discuss the details with him next month during the Interkoi Germany.

Anyway, my supplier also said that the drum filters offer better benefits and even using a bead filter it would be recommended to run a drumfilter before the beadfilter.

With "quite a few" benefits I meant that there are actually a lot advantages:

-no backwashing, it is done automatically
-only 10-15% of total pond volume needed for the filter (bigger ponds might even need less than 10%)
-less workload for the bio chamber resulting in higher biological capacity
-almost any daily food dosis can be fed even in small ponds
-expected better growth rate for the koi
-expected less bacteria pressure in the pond resulting in less vulnerability to bacterial deseases
-more stable water parameters

The best is to come and see it :D

Hi again pak...sorry for asking too many questions....when you started insatalling this system...I assume you are totally rebuild your your filtering system. My question is do you still need to wait for the water mature to get clear / healthy water or is it 1 of the benefit is you can good water on the 1st day?

Hi Pak William,

generally the qulity of the water will be very good from day 1. However the filter bacteria (Nitrosomonas, Nitrobacter) needs to grow first. Therefore we also need to start feeding slowly and increase the amount of feed within the first 2 weeks. Due to the high water temperature here there will be a good bacteria polpulation within that time. To fully mature every filter will need up to 6 month, whatever system you use...

Maybe better from now you posting the pond picture when you start this filter system (of course with the fish inside). Then, 1 - 2 months later you posting again the pond, so we can know the fish growth with this filter system. It's suppose to be good (I think bro) :wink: :wink:

Sven, proper use of bacteria starter (that you always have different idea than mine :lol: ) would settle the issue or at least accelerating it ..

Hi Pak...we are all eagerly waiting for your posting of your first Koi into new filter system. 1 more question pak. Do u still need bakki shower with bacteria house? In my opinion, the price you mentioned earlier...I think will be cheaper than using bakki shower with bacteria house...at least in my case. My pond is about 45 ton...have checked with some people and suggest me at least I need more than 200kg bacteria house. Today I'm using conventional filter system ( Chamber ) and plus 1 Hayward Filter for swimming pool ( sand filter).

Hi Pak,

I was in Pondok Gede today and wanted to take photos. However the filter starter made the water a bit milky so I need to wait another 1 or 2 days. Otherwise it looks a bit strange :lol: . The system I installed does not require any bacteria house anymore. The housing for the bacteria is the Helix (it's the same like Kaldnes). Depending on the fish load/ amount of daily feed I can fill a matching amount of Helix. 100 liter of Helix can clean up 0,5kg of food per day. I currently use 300 liters so I could feed up to 1,5 kg food per day. As my chmaber has 2,2 tons water capacity I could fill up to 650 liters of Helix and feed up to 3,25kg of food. The bakki shower is also a good system. Very high surface area and good aeration due to the water "trickeling" down the tower. However for a house it might be quite noisy and as far as I know it does not come cheap :wink:

Hi Pak,

since I found the PE version it now comes very much into the "normal" price range :D . The stainless version is still quite high in price but it is really an amazing machine.

Hi Mr Sven, :)

About the waste in the drum, during the cleaning process they will drained through drainpipe inside the drum. I assume the drainpipe has its ownvalve which automatically closed when the cleaning process finished. Is this right?

Hi Pak,

no, there is no valve needed. The waste water pipe goes directly into the drain. The tray inside the drum is above the water surface. The drum is not fully submersed.
