If you are only using a single gas, selecting "dump" for the unused gas will vent it to the environment, preventing that internal tank from filling completely and stopping the Separator. Since Mekanism 7.1 (Minecraft 1.7.10) the Electrolytic Separator requires 400 joules of power per tick, ...

The Electrolytic Separator requires energy which can be supplied by a generator, energy storage cell, or cable placed on the side with the socket. In addition to the machines from Mekanism, the generators, energy storage cells and cables of all supported power systems (IndustrialCraft 2, Thermal Dynamics, BuildCraft and Tesla) can be used to supply it.

Optimal power setups for the Electrolytic Separator.
If I remember correctly, and 1 Mekanism Joule (the units of power) is equal to 10 RF (and they should be, unless I'm confusing them with Eu, although I think that was 2.5 or something), the Electrolytic separator uses 4k rf/t on DEFAULT configs - 400J/t (info taken from the mekanism wiki). Now, this shouldn't be too hard to achieve... some solid fuel generators will help, and you should definitely be storing energy up even if you're not ore processing - I made an automated and entirely self sufficient (within one chunk, aside from brine production) 4x ore system with Mekanism, using factories, which increase efficiency (I believe it uses the same gas or whatever to process a full factory at a time versus one machine at a time, so anywhere from 3-7x efficiency improvement). Also, no matter what, any unused hydrogen should be burned in the generator (if it's still around in the latest Mekanism... not 100% on that). Your goal shouldn't be to make more chemicals for processing, but process in the most efficient manner - Mek is GREAT for saving space once you figure out what machines need what. More on reddit.com

Electrolytic separator output sides.
Either the Electrolytic Separator (ES) is auto-ejecting into the GG, or else the GG is 'pulling' from the ES. I believe Mek has some quirks/bugs as related to gases and certain machines. I believe most/all of these can be solved by using Mek gas tanks (instead of pipes) directly on the machine. ... Did you set the pressurized pipe to extract with the Configurator from that side?

r/feedthebeast on Reddit: Optimal power setups for the Electrolytic Separator.
August 21, 2015 -

So in order to get more ore with Mekanism you need oxygen and you need an Electrolytic Separator for that. I used all 8 energy upgrades and it still chugs through power like there is no tomorrow. I then built a big reactor and I still have a power deficit. I was running on 5 Advanced solar arrays before the reactor. What would you all recommend me using to even out my Power usage/creation scale?

November 10, 2016 - I understand I can use water buckets, but I have to do that manually. I tried using an electric pump by setting it on water surface and even tried 1 block above water surface. It say says "No fluid". I need a system that powers the pump, and connects the pump to the Electrolytic Separator.
