Coke Water Filtration System

[menace2asu]

Good Morning,
Have any of you gentlemen heard of or worked on a Coke Water Filtration System? I have been tasked with renovating the current housing. Below are some site pictures I took; I've tried doing research online to find more information on it, but have had no luck. Any information or nudge in the right direction is greatly appreciated.
Regards,
Scott

What you have is a coke tray aerator.

Coke tray water-fall aerators consist of a series of coke-filled trays through which the water percolates, with additional aeration obtained during the free fall from one tray to the next.

These were used more than 50 years and have been mostly supplanted by plastic or metal tray aerators.
