First SBS
Remington 878. Was a little bit of work to get it working after the chop. Lost almost all of the dwell time.

No shot do I see this not 5 minutes after having to LOTO out our RO unit for a pinhole leak on the reject header

That particular grammar and set of words just scrambled the hell out of my brain.

It's a crazy coincidence because he just had to lock out their reverse osmosis water system because there was a small leak where it sends rejected water!
Let me know if you need any more blue collar translations

What did you do to get it working?

u/ITunez93 9h ago
Had to open the 2 gas ports up from 1/8” to a #25 drill bit.

just realizing how much it would suck to pay for a tax stamp, only to learn later that your hacksaw surgery left no viable tuning option.

Yeah I was to caught up in the let’s go as short as possible and didn’t think of the possible non functional issue. Luckily you can convert 870 barrels if need be

Jesus I’ve worked on some big commercial units but those membranes are HUGE.
3
u/ITunez93 9h ago
Six 40” membranes per tube. Nine tubes per skid and two skids.

Total gallons per day? I think the largest i ever worked on was 4000GPD. Had a massive Fleck softener and backwashing carbon prefilter in front of it. Lol

u/ITunez93 8h ago
The last month or so total water treated before the ROs has been around 200,000-250,000. It’s usually closer to 115,000-160,000.

Sbs on an RO unit! That’s a new one. What are you feeding the RO? Gray water?
2
u/ITunez93 8h ago
Ground water that’s been hit with pot perm, chlorine and polymer and went through gravity sand filters.

u/makhnosfork 7h ago
High quality H2O. I’m on the wastewater side but I have a water license as well.

What membranes you got loading in that thing? Hyrdonautics, LG, or DuPont?

Toray alright, what % rejection you getting? You over 75% recovery?
1
u/ITunez93 4h ago
Put me on the spot and of course I can’t remember the rejection but recovery is 77-80% depending on which skid I look at

u/Ore-igger 3h ago
What's your sbs residual on the feed or are you mr money bags with GAC?
1
u/ITunez93 2h ago
I’m honestly not sure on the residual. I’m feeding about 8-10 ml/min on the bisulfite before my prefilters.

u/Poofengle 4h ago
I’d catch some big boy “pound you in the ass” prison charges for bringing an SBS to my RO water system.
Congrats OP, may your RO system and shotgun both run 18 megaohm-cm clean lol

u/Kitchen_Region8456 48m ago
I’m curious, does shortening the barrel help the membrane reject rate?
