Titrated Acid water wash.

[Jamesrl]

Wish me luck, I'm about to put 10ltr of hot-ish water with 17.5ml of 98% sulphuric acid into 100ltr of perfectly reacted bio.

I do hope it don't go belly up.

Jim you will be fine (trust me I'm a doctor)
Hopefully you will find like others that its so much easer this way

Good luck Jim.  Hopefully not with your new cottage industry Mayo

[K.H]

Good luck, let us know the result

[Julian]

Your post reads like you were going to add the water to the acid!  In which case all the wishes of good luck will be most useful.

I'm sure you know, but for others reading, you should always add the acid to the water and slowly.

It really is a good method, I'm sure you will get good results.

Jamesrl, water washing !!!

Has hell frozen over ?

Are we sure this is the same jamesrl ?

Do we have an imposter amongst us ?

He's not posted in the last two hours.... hopefully that 98% acid hasn't dissolved his trumpet (or anything else come to that)

I used the last of my concentrated Sulphuric acid up last week. I am now onto the 20+ litres of 85% Phosphoric Acid that I have tucked away.
Whilst I'm sure it could still do some damage, it seems a whole lot less scary than the Sulphuric did.
I must remember to make up a new titration fluid with the Phosphoric though otherwise things could go rather wrong

Hi Julian
Do you want some dry acid when you come up next week.

[julesandtash]

I'm not sure that there would be a lot of point as I would have to add it to the water anyway to get it in to the batch.
Worth a go if you are donating samples though.

It looks like all systems are go for Friday, should be up just after lunch if that is OK and will have a trailer full for you.

It does mix with water much safer than 98% sulphuric and @  5g pL  it brings the ph down to 1 so should be easy to make up a good and strong 25L tub at a time then just add required amount to the batch rather than having to mix acid with water to get the acid in the batch.
Yes I have a bag of samples going out for trials

[jgs600]

did a batch myself a couple of days ago, after doing a quick 5% water wash with the left over glyc in there i did my normal 40ml of acid and 10litres of water, no problems, have now done another 3 x 10litres pump washes and all is well,

[Jamesrl]

Yes it' is me doing water washing with acid and feck it's cold here, cold enough to freeze hell.

Julian, I did add the acid to the water, I might be mad but I ain't daft.

What I did.

I mixed 1ml of sulphuric to 1lt of deionised water as atitration solution.

Ipa and 10ml of Bio (after a good 10/90 with zero dropout) on me Mag stirrer with the blue stuff in it

I used 1.75ml to neutralize the caustic so 1.75/1000ths of concentrated acid to 10ml of Bio.

0.00175ml = 10ml,

0.175ml = 1ltr,

17.5ml = 100ltr

So 17.5ml to 10ltr of water for the first wash.

Not only did I use the pumps but engaged all three Eductors to boot, NO mayo, whopeee doppee do.

Second wash coming up.

[Carrington]

Cool

[Jamesrl]

Cool

No, it's hot.

What made you try this jim, is it just out of curiosity or necessity?
