Reply to comment by gunplumber700 in Recycled wastewater is not only as safe to drink as conventional potable water, it may even be less toxic than many sources of water we already drink daily by giuliomagnifico

Please eli5- a low effluent turbidity.

Also could tell us the reasoning of moving from gas to liquid Cl?

Turbidity is the cloudiness or opaqueness of water. Essentially how clear it is, an indicator of how much stuff is in water.

Effluent is water leaving somewhere, the context in which I used it is leaving the plant.

Chlorine gas is cheap and effective as a disinfectant, but is one of the most hazardous substances to work with. I’m a little rusty from being out of the industry since I was forced out of my job, but the osha limit is 1ppm over a 15 minute period and the idlh (immediately dangerous to life and health) threshold is 10ppm. It expands roughly 430 times it’s volume when moving from liquid to gas, a small leak can quickly fill a room and incapacitate someone. This is relative to

Most people that don’t control the budget for things like that prefer some type or variation of sodium hypochlorite (bleach, much safer) because it’s much safer to work with.

Thank you for the great explanation and I didn’t want to assume.

Oh so they’re moving to liquid sodium hypochlorite, not to using liquid chlorine. Knowing that chlorine is a gas under normal circumstances I was curious why would water treatment plants choose to move to it. Now liquid “bleach” makes sense from a defect and cost standpoint.

Water is so essential to our very being and waste so much of it.
