Funny...I have that exact dual input TDS meter, and the componentry of an RO unit and what looks to be a manual mixing chamber...
So if I'm correct to assume, there is nothing there that automatically mixes the RO water with "wastewater" to achive a desired TDS, this is a manually adjusted system? What if the incoming is 7.0Ph and 150ppm TDS How are you going to achive an 8.2 Ph with 197ppm TDS?
Hardly a set it and forget it type system...My incoming TDS changes from the tap to much to have to readjust manually.
You should have just posted the picture and been done with it. It doesn't take a genius to tell you that alot of people are using the same components to achieve these results. They are implimented into some of the auto waterchangers/drip systems.
What you don't see in the picture is the overflow system, that allows for water to go to waste. I know it cannot be a recirculating system, because you are not allowing for Pheromones and other organics to be flushed from the system...(why weekly waterchanges are so important and necessary)
I'm sure when you stated that the unit should cost 400.00 you did so knowing the cost of the components in the above pic can be had at 200bux retail, tops!
A shadow box with a pegboard background doesn't require engineering or 100K to get tooling and 25 samples.
See how that works...maybe you've heard of this one...

Keep in mind a patent is only as good as you can enforce...
If your product is a hot seller, be absolutely sure there are people out there that are going to copy it, change it just enough, and then bring it to market so fast you'll think it was their idea...
And while you try to tie it up in probate, they'll have sold enough of it and made all the money on it...then when you get a judgement on a patent infringment, they'll be sipping margaritas with those cool little umbrellas on a tropical beach much nearer to the equator that Mi...
Hows that for Bursting your BooBles?
