Backyard Aquaponics
A place to discuss aquaponics

Hi there,

I'd like to know if any of you already succesfully reparaired his drumfilter mesh ?
And more important, I'd like to know how ?

Thank you very much !

i believe epoxy glue/resin is what does the trick, a few of our panels have some repairs. just completely patch/cover that one square.

What brand/model of drum filter? Something like a hydrotech you buy a square plug and stick it in the place where the screen is cut. Other models (youre in France so maybe using Faivre) you have to buy a replacement panel. I like the epoxy resin idea but haven't tried that.

Anyone have any reviews of the different RDF's?

Anybody used or have any info on this one? It's pretty basic, not a lot of electronics...which for me is a plus. More mechanical means I can fix it and not have to spend money on panels, etc. Confident in most mechanical fixes, fabricating, etc. Not so much in my electronics ability. I can wire up panels and house wiring, but repairing circuit boards and the like is not something in my repertoire. lol

do any of them have complicated electronics? they have a motor to turn the drum and a pump to squirt the waste off. They then either have a switch that turns on when water reaches a certain level or they dont and run 24/7, pretty simple either way.

Yes on the electronics. Many of the higher end ones have a fairly large amount of electronics. My point was was, you could use a simple timer and adjust as needed.

we have 3 hydrotechs here ranging from old to brand new the brand new one is about the size of a small car, and they are all just as simple as each other. ive seen one at another facility that reported the height of water coming in to control board but that was an aftermarket add on for the facility i believe. the three we have are just switches and relays inside the box, nothing fancy at all.

what are the high end ones?

I guess switches and relays aren't too bad, i would prefer a standard timer, with no switches or relays. Just like newer cars, the more computers, MAF . TPS, O2, and additional electronics, the more things can and will go wrong. An HEI ignition with 2 wires with a throttle bottle injector or better yet Holley 850, suits me just fine. To each his own, I'm sure the relays and sensors are reliable and give additional control over the unit's functions. I ripped out the computer on a Bobcat skid steer and replaced it with an earlier model switched unit because it kept shutting down due to a solenoid or sensor from various things it was supposed to be monitoring. I can monitor just fine with a temp gauge and hydraulic pressure gauge. Had many and never had them stop like that machine did. All directly tied to the computer and their techs could never figure it out. After warranty, it all came out. Took a while to get the bugs out, but she runs perfect now.

thats the inside of the big new girl at work, i believe its just 2 overload switches bottom left, 1 contactor top left and two time delay relays top right with two switches on front of box for power and auto/manual/off switch.
