Hey everyone, this is a basic guide to planning out a RO (reverse osmosis) and hydroponics water filter. This instructable will provide some basic steps, personal experiences, and information you will need to help you build a RO hydroponics filter. We wish you luck on your building experiences and we hope you find this helpful.

Step 1: Draw It Out!

Feel free to go as crazy as you want in this area, it's your design we're simply here to guide you down the path. My group mates and I all took white board markers and went crazy. We have found that drawing out the water flow and basic portions of the system helps. Here is an example of our brain storming process

Step 2: Name Your Basic Components

Again we would like to remind you that you have free reign over this portion. These are merely important factors to consider. We found that we needed the following:

  • Residential semi permeable membrane (RO filter)
  • Powerful inline pump
  • a pipe that can create at least 60 psi
  • Gutters or pipes (for plants)
  • Water Catch
  • Plastic tubing
  • Tanks

Step 3: Create Your Measurements

We can't really suggest much for you on this step due to the uniqueness of each situation. Make sure all of the measurements use gravity to your advantage and are to scale. We personally recommend starting with a 45º- 45º- 90º angle to start for your hydroponics. All other measurements should reflect your size and shape of your available space. We used:

  • 3.3 feet hypotenuse
  • 2.3 feet height
  • 2.3 feet base

Step 4: The Tank Setup

One of the most important parts of your filtration system is the tanks. This is where you hold water at the different parts of the process. We recommend 4 tanks. One for dirty water, one to catch the water at the end of the hydroponics system, one to hold filtered water, and one to hold and access drinking water.

Our design consisted of placing the dirty tank on top of the waiting tank, and having the drinking tank attached to the side of the waiting tank. This allows our design to only use one pump. Our measurements were:

  • Dirty Tank:

1 foot; 1 inch tall x 1 foot; 1 inch width & length

  • Waiting tank

6.5 inch tall x 1 foot; 1 inch width & length

Step 5: Now Just Build and Remember to Check Before You Drink.

It's up to you to put the pieces together now. We hope this has helped and want to offer some last pieces of advice.

  • ALWAYS test the water before you drink.
  • Clarity and PH are extremely important.
  • Water quality is often an indicator of the systems functionality

Thank you for reading and we wish you luck in your building.

<p>Very interesting! </p><p>Have you built this actual system (or are you planning to)? It would be great to see some photos of it if/when you do! :)</p>
