Default D.I.Y. Micro Strainer

Hi Guys/Gals,

After a long researched, I finally decided to make a micro strainer. Got this idea in another koi forum.

Size is 260mm in diameter and 300mm in height. This will go in my settlement hoping it will reduce my maintenance a lot more.
Purpose of this strainer is to stop the micron waste going into prefilter. If this thing works, I will convert my prefilter to another bio unit

This unit will suit a blue drum filter or even a square chamber. The unit will rotate by vortex effect and also with the aid of the backwash system. So its a self cleaning unit. More on the backwash later.

Materials for strainer:
1 x 8L bucket with a snap on lid, 1 x S/S 280 micron screen, silicon, expandable foam and a piece of 10cm pipe as sleeve.

Materials for Backwash unit: (Will get later on)
20mm pipe, some elbows and a tee and a 3000Lph pump.

1st pic shows the rim of the bucket is being cut by a hack saw. This will be the top part of the unit. You'll see what I mean later on. I actualy cut the lip off the bucket ealier, this will secure the screen to the bottom part of the unit.


* 2nd pic shows the lid of the bucket, will be used now as the bottom part of the unit. Center hole will be cut to fit a modified 100mm pipe


* 3rd pic shows the 100mm sleeve which was heated up to stretch to 110mm diameter for clearance to slide easy to my 100mm transfer pipe.This will also help to float according to the pond water level.

Continuation:

* 1st pic - Shows you how the unit will be installed to the lid.


* 2nd pic - Shows the unit now glued together with silicon. Now I just have to wait for the glue to dry a little.


* 3nd pic - after the silicon had skinned I applied the expandable foam to the top rim of the unit. This foam is to aid the strainer to float, rotate and adjust accordingly. I used sticky tape to prevent the foam sticking on the screen. Now I have to wait atleast 12hrs for the foam to dry. Tomorrow I'll trim the foam with hack saw blade and will post more pics.


I trimmed the foam with a metal hack saw blade.


Looks pretty good so far

Con't:

Rotation is anti-clockwise at 9rpm


Here is the DIY spray bars after the test was a success. Sorry no pics taken during testing mode. Got too excited




The spray bars have diff slits on them, one has 4 slits and the other has 3 slits. I had same slits originally but they it will not clean the screen properly. I staggered them like this _-_-_-_ this way with right pressure it cleans the screen well.

Here is a small video taken during dry run.

Jon this may be a dumb question but here goes anyways. Where does the protein come from and what does it do to the koi?
