I have this to help with tip-ups and picking off hot parts…and it works like a charm cleaning the table of the bottom crap

I recirculate mine. Use a pond fountain pump. Big plastic bin. I dump a bunch of Arm & Hammer in it to make it alkaline. No rust or smell.

As far as the water!! I drain the tank into 5gal pails; let it settle. When I am ready to use the table again I pour the water from the pail watching for the solids in the bottom to come forward. I take this out and pour into a small leaching area. When the table is nearly empty I put the plugs back in and I remove the slats for cleaning. I use my Shop Vac. to remove the remaining sediment from the table. I put a baggie on my pickup magnet to remove large solids before I use the Shop Vac. When I am finished I remove the baggie and the magnet is still clean.

Well considering that we dug that metal outta the ground, seems pretty straight forward on where it can go. What do you do your grinding wheel metal dust?

There are laws and regulations on properly disposing of contaminated water, depending on where you live.
That is a true statement. However plasma table water isn’t considered contaminated, hazardous, or toxic.
× Your septic tank won’t like the metal.
× City sewers don’t care.
× Commercial shops evaporate the water and dump the solids in the scrap bin.
× Scrap bins are sold to reprocessing
× local dumps recycle metals
× Some yards will pay you for it.

The water out of a Plasma table is NOT toxic or contaminated. I just give it to the plants in my backyard and they absolutely love it. I drain the table after every single use - the amount of water used is so relatively little that I found it very hard to justify any system to reuse it, especially when I have to use fresh water anyway to irrigate the plants.

Rust isn’t magnetic. So your filter is essential to collect debris before it turns to rust which is almost instantaneous.
well…in the year I have been using my table…there is zero rust…I have pulled sheets off the table after cutting and a year later the scraps are still not rusty…
even the slag/dross in the tray is all magnetic and not rusty…
I use greencut…so nothing rusts and I live in climate that is one step away from Florida salt air for rust.

I use a bucket system, and it sounds like several others do too. I have some photos of mine in a thread.
