We had some time to mess with the CDI setup this week, so we cut out a new rubber gasket to place between the two plates and sealed the stack up without the electrode. Then we connected the stack to the filter system with new tubing and ran water through it to see if we had any leaks while also measuring the differential pressure flowing through the stack and whether the system’s flow rate was accurate.

Also, we finally placed an order for the carbon electrodes. Seems like forever since we began looking for them and we still weren’t able to find a company willing to sell us a larger electrode. Thankfully, the small company that we bought the thinner electrodes from suggested a couple of other contacts that might be able to help us out, one contact being a professor at Case Western University that might already have electrodes that meet our specifications. So, we contacted him and he responded not even 3 hours later, saying that he had 8 electrodes that met our specifications and could send them that same day, no charge. What luck, eh? Anyway, our week ended on a high note and all the electrodes should be here by Tuesday 🙂
