Controlled water recycling

Guide is a work in progress. Just threw this together at 4am and it could use some optimization and automation, however in its current state it is rather effective so far in generating clean water for me. Once I remake this into an optimized automated version Ill update this. Dont have screenshots up for it as I just took snips to make it cleaner from my mess of a base.

(Going to make a better setup guide at a later date)
You will need an airtight area filled with chlorine gas. Chlorine gas will kill germs in reservoirs which is rather useful for creating any kind of liquid cleansing system such as this.
(build it in an area with preexisting chlorine to prevent other gasses from entering the area)
Once you have your airtight area and its filled with gas construct 3 layers of reservoirs. You will chain then together and each layer will perform any one given step of the cleaning cycle.Reservoir filling, water de-germing, and Reservoir emptying. This means the system is always accepting new water and should always be outputting clean water.

The power required for this system is rather minimal. The only thing necessary is the 6 shutoff valves. The doors I added purely so I could tell which reservoir was being used.

The most important and complicated part of this system is managing which of the 3 reservoirs is currently in what state (and its not that complex once you set it up). For this I am using a pulse generated by a buffer(set to the minimum), XOR, and a switch. Whenever I toggle the switch, regardless of it going on or off, it emits a pulse to update the next set of gates.

The set of gates controlling the reservoir states
(NOTE : There is a switch between the top two gates. It is very important that you turn this switch on ONCE WITHOUT USING THE MAIN SWITCH, this sets the initial state of the system. Once it has been turned on once you may deconstruct it as it wont be of use anymore)

In the future I will update this system with an automated toggle so that once the actively draining reservoir runs out it swaps to the next, however that kind of system is capable of failing easily if not given enough water so I will see if it is worth upgrading this system.
