      Talking My D.I.Y. Microscreen...

      Hi Guys/Gals,

      After a long researched, I finally decided to make a micro screen, many thanks to Ryan S. Its a bit different from the creator...

      Size is 26cm in diameter and 30cm in height. This will go in my settlement hoping it will reduce my maintenace a lot more

      Materials for strainer:
      1 x 10L bucket with a snap on lid, 1 x S/S 280 micron screen, silicon, expandable foam and a piece of 10cm pipe as sleve.

      Materilas for Backwash unit: (Will get later on)
      20mm pipe, some elbows and a tee and a 2800Lph pump.

      First of I cut the lip of the bucket to use later. I'l explain as I go along. Then I cut the rest of the rim to use as my top part on the unit.(see 2nd pic)

      1st pic is the lip of the bucket. 2nd pic is the the rim being hacked 3rd pic is the lid of the bucket which I'll cut a 115cm hole for the sleeve. 4th pic is the sleeve glued to the lid. The sleeve was heated up and enlarge to create clearance in my 4" trasfer pipe. And the 5th pic showing the screen is being installed to the lid sandwich by the lip. I've decided to do it this way just incase I have to trim the screen

      Con't.

      Pic 7 is the complete unit. I only used glue on the top bit not on the base, as previously shown the screen on the bottom part was sandwich with the lid and the lip bucket. I reccessed the sleeve a little to give some room for the unit to follow the water level when it drops.
      Pic 8 was a bit messy task and had to hang up the apron for the day waiting for the foam to dry
      Pic 9 Early in the morning trimming the foam
      Pic 10 is the complete micro screen assembly

      Great job Jon, glad you decided to post your/Ryan's design modifications.
      Using the bucket closure to hold your screen .
      Posting pictures, usually the pictures show up in the thread in the order you upload them, the first picture you want us to see in other words upload it first and so on. At least it works that way for me, maybe it is back wards since you are sending them from down-under.
      Thanks Jon, keep us informed, we want to see it in operation.

      Pic 11 is just testing for clearances and flotation

      The other pic shows the backwash system. I have made the slits staggerd so I have 4 slits in one bar and 3 lits on the other bar

      This unit has been running since this morning and so far the performance is good

      Check it out

      I looks very good, first one I've seen outside the USA. Good job! You sure trim foam much neater than I do.

      The thing that concerns me is the silicon glue. The SS mesh to bucket seal is one of the tricky parts. Almost nothing sticks to the type of buckets used in the US. Its very importanat to ruff up the contact area with a sanding pad. Also Epoxy or JB weld will hold up better than silicone. I think you will still be OK if its a good quality silicone.

      I am not sure what is holding the top rim to the screen. Is that another rim and lid from a second bucket? Also...are their fins on the underside of the foam to make it catch water and turn? And one more question.....where can I buy some microscreen? I want to try one of these....I love it!

      Have you tried 3M's 5200 fast set, many people swear it holds everything?

      Nope. DAP 50yr clear silicone (you can get at Lowes). HD does not sell anything "good". Many good epoxys, Lowes sells the larger packs of Devcon which is OK.

      AES carries many sizes for around $15 per linear ft, which is what you need for 1 microscreen. Recommend 250 micron for most applications, indoor or very clean ponds 180 micron. Fins are not needed on microstrainers since the spray bar can turn the unit, also the vortex action turns the unit anyways. Around 3 RPMs with just vortex and 7 RPMs with spray bar also.

      I have noticed the ones with fins do rotate better.

      I think Sandy built hers with fins....not sure though. It would be easy to cut slots in the foam and insert plastic fins.

      Why are microscreens so much to buy already built? It has always made me ponder....

      Jon, That is a cool microscreen! I think I under stand microscreens now! So does that foam make it float? Or is it just a sealent now? That is very cool!
      Thanks Marshall

      The foam does let it float and is the top of the moicroscreens. All the ones Ive seen have foam.

      I assume that you bought your screen in a sheet...how did you connect the ends to form your cylinder??

      Hi Ryan,

      I did sand the area where the silicon was applied plus I have the foam to hold the to part of screen in place, also the way I assembled the bottom part of the screen I doubt it if it falls apart

      Looks good. I LOVE the DIY Microscreen. by far the easiest, cheapest and more effective DIY mechanical filtration I have seen.

      Thanks Ryan!!!!!

      Hi Carol,

      If you look at pic No.2 you'll see I was cutting the rim off, under that rim there is a kind of void. The screen went in there and filled up with silicon. No I don't have any fins in the drum but I'm already thinking of adding some. But then again I think I have enough rpm in there

      If you look at the pic below this might explain a little more how I fixed the screen to the top rim. I onlu used the top part of the bucket and the lid, nothing else.

      rgds,
      Jon
