Trident NP Waste Container Crystalization.

[Mkkari]

Hello,

I am using an acrylic container for Trident NP waste collector. I understand this is against their recommendation. However, I am curious about the crystallization (PFA pictures) and would like to take safety measure handling it whenever I will have to empty it.

Let me know if any additional information is required.

I changed my np reagent for the first time last night and the end of the waste line had solidified into a brick of something (kalk+idk). I’m using an HDPE bottle

I’m unclear what we are seeing in the picture and where exactly it is.

I'm curious about this as well. This appears to be Trident NP discharge line in the waste container.

Against Neptune's recommendation I'm dumping my Trident and Trident NP waste into the same container, at least for now.

I heard the neutralizing agent is basically just kalkwasser?? I'd like confirmation on this or an easy alternaitve neutralizer I could use. I'll be needing to neutralize additional waste with my approach, and I do not want to purchase a 2 month set of reagent just for the neutralizer.

Thanks!

It is a trident NP waste line being discharged in an acrylic container.

The neutralization powder is calcium hydroxide. Feel free to create a support ticket for confirmation. I use a separate container for my NP's waste per their recommendation and after reagent replacement, and waste, I see crystalized chunks. I place the cap on and shake over the utility sink. Let it sit for 5 to 10 minutes. then discard.

I understand space may be a issue for some as it relates to the waste container but hobbyist should really follow the directions in this case.

Specific information on neutralizer they use can be found in their FAQ:

Thanks! I suppose I would like someone to clarify why. It seems like maybe it's because of how acidic the waste is... it's not like putting the two trident waste's together is going to create mustard gas... or is it?

Two reasons that I'm aware of. The first one to do with the NP having its own container requirement of glass or HPDE.

The second reason with regards to mixing the two sharing the same container, assuming you are using a HPDE or glass container, is because the waste container size settings and estimated waste measurements of the Trident and NP are separate. So by using a single container the estimated waste volume will not be correct.

Thanks again for the insights. FWIW I did just order another waste container. I'm going to try to make it work with two waste containers, but space is certainly an obstacle.

Not intentionally trying to be contrarian here, but my container is a 4L Class 2 HDPE and both Tridents are set to think their waste containers are 1.75L, respectively.

My thoughts are to simply empty more often and neutralize more often.

Seems to me with the right safety precautions, you could empty into the same waste container and not worry about neutralizing until you go to dispose of it so you don’t ruin your sink/toilet/pipes.

By safety, I mean you should ideally use a safety can with manifold and carbon filter as we use in industrial lab settings for community liquid waste, assuming basic compatibility. If you search google for “HPLC waste manifold” you can probably find the parts you need to put something together. For example:

That would certainly do it, but I wonder if that is solving a problem we havent defined. I guess the real question to ask is, does combining the waste streams with calcium hydroxide produce any secondary reactions that cause the combined waste to become more toxic/dangerous OR the waste to produce gasses that could be toxic/dangerous?

Honestly I don't see the big deal about neutralizing or not. I just poured mine out lol. I looked at the SDS sheets and everything came back as "mildly acidic." With modern plumbing and a good rinse down the drain there aren't going to be any issues. I'd be worried about cast iron.

But I also returned the point of sale Trident NP.

There are quite a few things calcium hydroxide will react with to make harmful fumes. Things you don’t really want to mess around with, like hydrogen chloride and hydrogen sulfide gas, or even chloroform…

Anybody have a respirator that wants to pour the reagents together and find out what happens? Kidding, but not really…

I think someone from neptune should address this. I can't be the only one doing this. How do you tag them in here?

I’m sure they won’t. Too much of a legal liability to tell us its OK with caution, and an intellectual property risk to tell us exactly what the reagents are for us to make our own decisions.

Welllll dang! Guess I'll separate them ...at least until I hear more... perhaps I'll put a ticket in and see where that takes me. Thanks for your input!

Yep, I would still try the ticket. I’m just speculating. Or make/buy a vent filter and use an airtight container with tube fittings if you want to continue and de-risk any potential fume exposure there may or may not be.
