Re: [micky] DIY Filter Using Huge Chemical Drums [In reply to]	Can't Post

Hi Micky,

Very nice & professional drawing. I wish I can draw like you. Also, as the saying goes like: a picture can tells a thousand words.

I used to have a similar drum filter configuration like yours. The setup was exactly the same initially but I later relocated the internal vertical inlet pipe to the outside & have the inlet bulkhead near the base of the drum to facilitate the accessibility to the filter media in the drum without the vertical pipe interference while cleaning the drum. I have to do this becoz cleaning is a periodic & on going job. I hate this part of the filter maintenance. My original design was to relief the pressure from the pump by not having to push the pumped-up water against the massive drum load that was why I have the vertical pipe inside the drum like yours to have the pump outlet a free-fall flow into the vertical pipe inside the drum thus without bearing the weight of the water and also to prevent the drum water to flow back into the pond in case of pump or power failure. Now with the vertical inlet pipe relocated outside the drum has ease the cleaning process substantially. I suggest it is beneficial to relocate the vertical internal pipe to the outside of the drum for the same reason.

I hope this helps

Cheers

Hi John,

Sorry for the confusion. I know I'm not a good illustrator especially with words. At the moment I'm not ready to make any sketches. Hope you can bear with me for the time being.

Actually I was trying to explain from the above, Micky's drawing. I was saying I used to have the same drum filter setup before I made the modification. I reworked my drum filter after I discovered that the pipes inside the drums were the nuisance when the filters were due for cleaning. You can imagine the trouble to remove the jap mat, the net of shells and other media with the pipes in the way. From the same sketch you will see, the pipes that cut through the filter media vertically down into the bottom of the drums. The only change I made was the relocation of these pipes to the outside & routed directly through a hole near the bottom. After the modification cleaning has became easier. The drums & their media can now be cleaned at ease.

I Hope you understand this time.

Ps Pls refer to Micky's latest drawing. That was what I meant.

Micky,

Yes, this was what I was trying to say. With your sketch I don't have to explain to John in writing. I think I have to learn how to use the system to draw asap. We can't DIY with words alone.

Re: [cwnchong] DIY Filter Using Huge Chemical Drums [In reply to]	Can't Post

Micky and chong

Just wondering whether we can just connect the two containers using just one tank connector instead of with elbows. that way , we can save substancial space, you know with the elbow up and elbow down. I would gather that curvature of the drums may rise to some problems but with plastic containers , the surfaces are rather flat.

what do u think. B/4 i forget, Micky has earlier indicated using O-rings for the tank connectors and it had been proven that watertightness is more effective than using silicon( just for info)

Re: [mattloui] DIY Filter Using Huge Chemical Drums [In reply to]	Can't Post

Matt,

It is okay to connect the 2 drums with one straight connection instead of elbows if the configuration is an up-down/down-up flow. For the down-up/down-up setting, the elbows are necessary.

Regarding the space saving between drums, the drum can be placed almost touching to each other with its elbow located 45 degree linking to the connection pipe to the next drum. You may imagine from a plan view (looking down from the top). 2 cycles touching each other to represent the 2 drums and the elbowed connections meet. I wish I can provide you with a sketch, but unfortunately I am not ready to do this at the moment. May be Micky can help with a drawing. I suppose the drums can also be clustered together with their connections linked to one another.

I hope this helps

Re: [mattloui] DIY Filter Using Huge Chemical Drums [In reply to]	Can't Post

Hi Matthias
Sorry I missed this thread about the straight connecting pipes. I have tried this and it seems to work fine, but only on one condition, you must never bump into the containers because a tiny crack from the glue joint will trigger a leak - that's why I switched to using o-rings which allow you to have a water-tight joint - the compromise is sacrifing a little more space for elbows ..etc. Hope this is useful.

Hi Jamie
You may go to Hock Ann Seng Industries Pte Ltd, No. 7 Tuas Ave 18. Buy the 120litres drum, choose those that looks the cleanest & smell the least. Don't foget to scrub the drum & cover thoroughly. I bought 10 drums @$14 each, you may have to pay about $16 if buying less. Good luck! Smile

Oh, Micky

It is real cheap but a little far for me as I am getting one too. Sungei rd sell about $20 - 30 for a biggest size. I think there are three sizes in the market.

Re: [koifun] DIY Filter Using Huge Chemical Drums [In reply to]	Can't Post

Dear All,

I have to agree that nothing is more satisfying than when you DIY your own filter and it works.....not to mention that the money you will save.

Just one personal experience I would like to share. If you use a chemical drum and just cut a hole at the bottom, it is very difficult to flush off the debris. To be very effective in flushing, the bottom has to be vortexed and the slope of the bottom has to be more than 45 degrees. Otherwise, you will still have to open up your filter very often to do a physical wash down like what I'm doing with my fiber glass filter since the bottom slope is not steep enough.

Cheers,
Patrick

Re: [steven yue] DIY Filter Using Huge Chemical Drums [In reply to]	Can't Post

Hi Steven
I pulled this list from a file and hope it is useful to you.

Supplier List:
1) 6-pc hole saw set KW04-9306 ($8.75)
Co: Homely Hardware Pte Ltd, No. 1 Ubi Crescent
2) O-rings 2-326 ($0.50)
Co: Able Hydraulic & Industrial Supply
No. 6 Ubi Road, #01-06/07
3) Pipe accessories
Co: Nam Seng Huat Hardware & Engineering Pte Ltd
Blk 3005 Ubi Ave 3 #01-60
4) Pvc pipes & ball valves
Co: Bee Jin Enterprises Pte Ltd
Blk 3027 Ubi Road 1, #01-144
5) Pvc pipes & accessories
Co: Kindly Enterprises Pte Ltd
149, Sims Avenue
6) Recycled containers 120litres ($14.00)
Co: Hock Ann Seng Industries Pte Ltd
No. 7 Tuas Avenue 18
7) Filter media (J-mats & coral chips)
Co: Mainland

You can get the connectors from most pvc pipe shops, some sells the o-rings as well. Just remember that the o-rings are different from the normal washers which has a flat surface. If you cut the o-ring the cross-section view is a circle.

If the drum filter is outside the pond/tank then there must be absolutely no leaks, if inside/above pond then small leaks are OK.

To make the joints at the drum really water tight, you will need a pipe tightener which looks like a huge plier. Also use pipe glue will to seal any tiny leaks at the joints/connectors.

You may wish to consider having the pipes betw the drums constructed outside, this will let you have the inside obstruction free - see other threads on same subject.

If you need any further help, just drop me a line. Goodluck!
Regards, Micky

Re: [micky] DIY Filter Using Huge Chemical Drums [In reply to]	Can't Post

MIcky

I always wanted to get o ring but to no avail. Instead, I get a piece of inner tyre rubber to cut it to shape - just as good. The 6 pcs saw set for holes drilling at $8.75 is cheap. I use to buy separately and cost a bomb - good to pass information around for DIYer so that your DIY is worth the effort and not ended more expensive. Hehe Sly

.

Btw, I never buy from DIY shops which sell much more expensively. Thing in Industrial parks are cheaper by many times. Sly

Hi Koifun
You are right about prices at DIY shops, its at least 15% more, but its always a good place to browse and compare prices.

About the o-rings, it depend if the surface is flat or curved. I guessed what you did should also work on a curve surface provided you use a few pieces to make it thick enough. Am I right? Smile

Re: [micky] DIY Filter Using Huge Chemical Drums [In reply to]	Can't Post

Micky, I found that o'ring are not so suitable when used without groove or housing. The o'ring tends to migrate when pressure is applied. Gasket or flat rubber sheet cut to size may be a better options; as what Koifun have done. It is also important that RTV or silicone sealer be used between faying surfaces to achieve a good water tight connection.
I hope it helps

Re: [cwnchong] DIY Filter Using Huge Chemical Drums [In reply to]	Can't Post

Hi cwnchong
You are right, o-rings are used only in a threaded "male-to-female" coupling. The diameter of the o-ring must be a very close fitting one, almost squeezing thru the threads.

You need to use 2 o-rings, one inside & one outside for a real water-tight connection, a pipe tightening plier is required to close the coupling real tight.

In my opinion, using glue on holes opened on the drum surface is risky because glue tends to crack on pressure. Its OK to use glue on the pipe joints.

Hope this clarify the use of o-rings. I think I did a sketch on this threaded coupling some time ago, I will try to trace it. Smile

Regards, Micky
