Looks very nicely organized. I am going to redo mine when I setup the new P120H rinse station

I have done it both ways. I believe @Neil.Antin noted what you say about the filter return putting a current in the tank that impacts cavitation. That makes sense to me although whether the return current reduces the amount of cavitation bubbles or just redistributes them around in the tank, I don't know. I have not noticed a difference in in sound either way.
Current in the water may keep particulate (dirt) redistributed in the water rather than allowing it to settle. I'll speculate dirt in the water gets filtered more effectively than dirt on bottom of the tank, but I have no evidence either way. Again speculation
For both wash and rinse I use a local brand of distilled water found at my grocery store, 99 cents a gallon.

The first weakness with your process is you are using the Liquinox way less than required. Use at 0.25% is not going to get the detergency that product can provide. As written in the book, the minimum concentration is 0.5% (vacuum-RCM) and for manual clean with availability of large volume...

Thankyou. that makes it easy. I will continue to get it from store as well.For both wash and rinse I use a local brand of distilled water found at my grocery store, 99 cents a gallon.

Hi
I think I need a bit more context on what you're doing. The set of steps in your chart, at least at first glance, look like they could represent an entirely manual cleaning process similar to what is laid out in Neil's PACVR book. I only say that as I see no step indicating use of an ultrasonic machine. Is that the case?
Are you looking to integrate ultrasonic cleaning with the steps in the chart?
Without knowing the answers to my questions, I can say the process I use is different although generaly similar in that I do a wash then rinse. My process, at a high level, is laid out in a couple posts, starting here:

I'm guessing you have or are looking at a different ultrasonic tank setup from mine where the rotisserie uses record label covers. No problemo. Does your rotisserie hold one record or multiple records? I'm guessing you do not initially have a separate rinse tank -- is that correct?
If you'll kindly answer the few above questions we can follow up from there.
edit: FWIW, their is a brief index to various topics in this thread, found on the first post.

For @tima benefit - the figure you provided is from the book. Otherwise, if you are going to use an Ultrasonic cleaner, you can skip the acid-clean step. The acid-clean essentially does chemically what the UT cleaner does mechanically.
But as @tima has indicated, this all fits within a total cleaning process which is then dependent on what you are cleaning - new or good condition used records, or dirty used records. In general, dirty used records will always benefit from a pre-clean step separate from the final UT cleaning. New records can often go straight to UT cleaning. However, new records that are delivered in paper sleeves can also benefit from separate preclean step.
For the UT clean step, if you are not going to DIW rinse afterwards, you can use just DIW or a no-rinse nonionic surfactant cleaning concentration that is addressed in Chapter XIV of the book. The no-rinse uses a high efficiency nonionic surfactant at very low concentration just enough for wetting. If you adapt @tima UT cleaning process with 2-tanks, the surfactant concentration in the 1st cleaning tank is 3X the no-rinse concentration to get detergency. But flea-market used records will still benefit from a pre-clean step.
Merry Xmas,

Extremely sorry for not providing the details. That picture is from Neil's book. I am trying to use Ultrasonic cleaner in this whole process and wondering what steps could be eliminated as a result? I am thinking ACID WASH and RINSE could be eliminated? I am using Ultrasonic cleaner (Elmasonic P120H) for both CLEANING and RINSING. Both the tanks have the respective filters (as per Neil's book). I have two types of rotisserie's. The one that can hold 3 records from Vinyl Stack and I also have the Kuzma rotisserie. I am planning on using the Vinyl Stack that can hold 3 records at a time.
Thank you for the link and I will read that through as well.

Hi Neil,
Yes, the picture is from your book. Thank you for the confirming the steps. The records are used with dust on them. I am planning to do the pre-clean step in addition to the UT cleaning. I will be adapting @tima 2 tank cleaning process. When you say surfactant concentration being 3X, I assume you are referring to the Tergitol/15-S-9 from 0.1% to 0.3% ?
Merry Christmas!
No. That picture is for manual-sink cleaning only. A Tergitol 15-S-9 no-rinse concentration for UT is about 0.005% (~50-ppm), so the 3X I discussed above would be 0.0150% (~150-ppm) which is close to what @tima uses in his 1st UT tank.
Best Regards,
Neil
Hi Neil,
I'm having hard time figuring out the 3X Tergitol 15-S-9 for Emlasonic P120H. Do I add ~1.5 ml of Tergitol/15-S-9 to P120H since it can hold 12.75 liters?
@tima - Wondering how much did you add the Tergitol 15-S-9 for your Emlasonic P120H UT?
Thank you both.

Here's the calculation: (12,750-ml) x (.015%/100) = 1.9-ml. For ease just round up and add 2-ml.
I add 2ml of the Tergitol 15-S-9 to my wash tank using this pipette:
If you have two Elmasonic tanks and a Kuzma RD I suggest you get another RD for the second tank. Yes they are kinda pricey but you won't need to transfer records from one rotisserie to the other in two lots. You'll save a lot of time and substantially reduce the risk that comes handling wet records. And you will be able to load a spindle with another batch of records while your first batch is in the wash tank.
Yes.. you kind of sensed my pain.
It will be much easier to simply switch them. I sure will do that. Thank you!Neil.. another question. Noticed the Meanlin pressure gauge was showing "0" on both sides of the filter canister. Is that normal ? I was expecting some sort of a PSI reading.
First it will always read near 0 PSI on the outlet because it's an opened hose discharging to the UT tank. If it's a new filter it's normal to read essentially 0 PSI at the filter inlet. Here is the cut-sheet for the 0.35-micron filter - https://assets.freshwatersystems.com/image/upload/s--troQwoDG--/cptkhyhvvsmvoa9r0g8v.pdf. If you look at sheet 3, and the pressure drop graph, the 9-3/4" 0.35-micron filter at 1.5-gpm shows about 0.25-psid. So, reading essentially 0 PSI at the inlet of the filter when it's new is normal for that gauge - it's not accurate enough to show fractions of a PSI. Over time, as the filter loads up with particles, the inlet pressure will increase. Since the gauge on the inlet is reading 0 PSI when new, when it reads near 10 PSI, replace the filter.
EDIT: If you wanted you could replace the 0-60 PSI gauge with a 0-15 PSI gauge - https://www.amazon.com/MEANLIN-MEAS...ace+dial,+glycerin+filled+,aps,76&sr=8-1&th=1.
