How Sewage Becomes Drinking Water

How do you make wastewater drinkable? It starts at the sewage treatment plant.
Ongoing droughts are straining the supply of clean drinking water. One solution might lie in an unexpected source: wastewater. Through a method of purification called reverse osmosis, Orange Country is making millions of gallons of dirty water drinkable again.

I wish that they would have explained the purpose of the aeration better. Adding oxygen allows bacteria to quickly use up the nutrients in the water. This has two purposes: it reduces biological contamination by removing bio waste. But it also makes it safer to return the water to rivers and oceans. Natural water systems would be thrown off balance with such a large influx of nutrients, causing such problems as algal booms, or deprivation of oxygen by bacteria that are eating up the nutrients and using up all the O2, suffocating other life. Which makes me wonder why California has been simply dumping waste in the ocean when they are ostensibly the most environmentally minded state, when other states have been aerating waste water.

It really is very clean by the time it finishes being processed. Most of it is accomplished by bacteria and bugs. It requires constant monitoring, documentation and constant adjustment to get the output water clean. The two main causes of problems in a wastewater system is chemicals that kill bacteria and "I&I" (inflow and infiltration) by rainwater.

It looks like California is attempting to do something that hardly anyone else is doing: that is to pipe the output of treatment plants directly back into the freshwater drinking supply.

@@djayjp You probably shouldn’t make judgements when you have little to no idea what’s being done. Nobody says that water was potable, only clean enough to be released. Do the Mississippi or Amazon rivers look crystal clear when they run into the ocean? Of course not. I’d pretty much guarantee that water being released is significantly cleaner than the water from a major river. Your brain is the end point of nearly 4 billion years of evolution. You should use it to think past, “Well, it looks kinda dirty…”

I see it more as a combination system. Reverse Osmosis is expensive due to the amount of pressure needed to force the water through the membranes. You could prefilter with larger micron filters that remove heavier particles but allow smaller ones through. Then you could utilize the deserts to focus sunlight to a focused point that then reflects down onto a greenhouse with a pipe at the top for the vapor distillation.
