Thank you for your comments Arash and Pooriya. We can discuss more permanent methods whenever you are available.

Dear Mikyle,

Thanks for your precise email. Thank you, Arash. I think Arash's idea is good. If we can find a basket filter with a low mesh number to put it on the sink, then we can simply dump the water, and the sludge will be caught by the filter.

Regards,
Pooriya

Hi Mikyle

Thanks for setting up this procedure which I think is good for the time being. I was wondering if we can sit together and look for something like a filter. Instead of going this long process, I am thinking we dispose the polishing waste into the filter from which the water is drained and the metal waste will be left. We can directly transfer the metal waste into drums.

I believe this would significantly decrease the work. I am thinking of a filter like the one that abrasive cutter has. It keeps the sludge and we can dispose that easily into drums.

Very Respectfully,

Hello ladies and gentlemen of NCAME,



This email is in relation to the waste management in the metallography lab. Usually when we are done with polishing processes, we discard of polishing liquid in the large black barrels near the door of the lab and once these are full, we request pickup of these full barrels. We were recently notified by Emmanuel that the polishing liquid was not hazardous, and we could therefore dispose of the bulk of the liquid in the drain once the sludge settles to the bottom of the barrel. Then, the sludge can be disposed of by the waste pickup team. There was also previously a habit of these large barrels piling up in the lab around the emergency shower area. This is not allowed as we need access to the shower in case of emergency. We are therefore attempting to put the following procedures in place.



I have created a rotation on ENG_NCAME Box in a new folder named "Waste Management" which is similar to the argon rotation. Two members will go to the lab to decant the barrels when they are full. There will be a total of 3 barrels in the lab at any time. Two barrels will be used for collection of polishing liquid from the polishers after use and the third barrel will be used to collect the sludge that settles to the bottom of these barrels after decanting - this barrel has been labelled as "Final waste for disposal". There is a hydraulic jack that we can use to lift the barrels up for decanting. There is also a hand pump on the floor next to the sink that will be used to empty the top layer polishing liquid. We went through the process of decanting during our lab clean up day but if anyone is unfamiliar, then please ask. Once the top layer has been successfully drained, the sludge can then be deposited into the third barrel. The lab must then be left with 2 empty barrels and third barrel with sludge. You may then input how many barrels were decanted on the rotation sheet (if one person decants one barrel then it counts as 1, but if 2 people decant 1 barrel it counts as 0.5) or you can let me know and I will update it myself.



If anyone notices that the third waste barrel is filled to capacity, then please let me know so that I can request pickup of the waste. The full barrel will then need to be moved to the powder room for pickup.



Also, a general note for waste management, if anyone has filled up any other barrels in the lab that need pickup, please let me know so that I can create a pickup and print a waste card. This includes the metal barrels that are used for sand.



The link for the rotation sheet is below.

Please let me know if there are any questions.

Mikyle
