Why is desalination so hard?

235 views

Every few years, you hear about some new revolution in the process, but nothing much after. Why is that? Is it very hard to scale up or…?

Also, is it going to become more viable as fresh water is becoming more scarce?

Thank you in advance.

Thank you all. So it was basically what I thought. It’s not hard to do, but it is not really feasible due to many factors.

I operate in the climate space but am not an engineer or expert in water resources. So remember that as I give my understanding. It is *very* expensive. It uses a lot of energy. And it changes the salivation of ocean water around it which probably is not a good thing. The salt must go somewhere. And it can mess with groundwater. It is a solution of last resort.

The primary and least sexy way to begin the fix is conservation in a serious way. No more golf courses. No more home lawns bigger than x. Make wicked sure agriculture is using water in a sensible way. This is very hard but crucial – tackle the water rights monster and make it realistic and sensible. And a culture change. If your clothes aren’t dirty you wear them multiple days before washing. No washing hair everyday. Maybe a shower every few days with quick ‘army’ cleanups everyday. I know this sounds weird or far fetched but it is these type of mind shift that will help us manage in days ahead.
