As an Engineer in quite a few disciplines I say it is, in fact, a filtration system. The pipe that rises upwards is a 'Bleed/Overflow' port similar to the air gap on a kitchen sink for the dishwasher. If your drain is clogged, the waste water comes out of the little cap next your faucet on top of the sink. This is an inefficient system that relies on gravity and does not supply a lot of water, by any means. It does make sense as you still would want a system that could operate without electricity, if needed. I could be wrong, and thats fine, but I am pretty confident in my analysis. Apologies if this bored you, thats just what Engineers do for no real reason other than 'It was there.' LOL
