Looks like a large protein skimmer on the left with two fluidized bed sand filters. Two big tanks on the right are probably for mixing/storing saltwater for waterchanges.
Lifeguard system?

DIY bioreactor for the biological would be the easiest and cheapest. You could always have it pouring in through filter socks for mech.

Correct. That's an RK2 pt skimmer for the shark tank being fed from two fluidized beds. Twin 1,000 gallon vats are holding water (left is SW, right is FW).
Are big fluidized bed / sand filters installed on all the big tanks ?

Not all of them. They were widely used several years ago. It's an outdated tech used to over stock a display and keep up with biological without taking up a large foot print. Current pressurized bead/sand filters do a much better job and don't give you nearly as many problems. The biggest downfall to fl beds like this is anytime you shut off the pump (power failure, sump goes low etc...), the media gets back siphoned into the pump and jams up the impeller. You have to take out the entire column and clear the media out of the piping and the pump itself (and pray you didn't destroy the impeller).
There is more detail on that particular system in my 5,000 gallon build thread (see link in sig) if you want to see it. Not really applicable to this thread since it's a marine system. I just used it for the illustration of a larger scale canister/cartridge type filter that works well.
