My friend's mother declined lung cancer treatment because it would have used up all her savings. She knew she was dying and wanted to leave some money for her children and have enough to pay for the funeral.

She died a few weeks ago.

Doctors said the treatment could have extended her life for a year or more.

Sunlight both purifies water, and creates more toxins.

Some water supplies have added a covering layer of floating black balls to prevent sunlight interactions in drinking water.

American here, 30, never been to a hospital outside of one emergency treatment and birth. Parents are junkies. I think I have depression and heart problems but I won't check because I live paycheck to paycheck. Gonna die soon. Kill your masters.

It looks like the cellulose is supposed to grab the dyes out of the water, and the exposure to sunlight is supposed to break them down. Whether they exfiltrate after breaking down, nor whether those degradation products are safe, isn’t clear.

If it does exfiltrate and it is safe, it seems pretty low waste, though. Otherwise, you would probably have to either swap the filters or recharge with fresh cellulose (and incinerate the old cellulose).

They don't dump toxic dye into drinking water. That's already very illegal.

In the USA, these industries are regulated by their local wastewater authority. They will have some pretreatment policy regarding these dyes.

This article is detailing a breakthrough treatment technology. Once this becomes industry standard it will likely be written into those pretreatment policies.

80% can be good, but it’s pretty dependent on what it is. Off the top of my head, I would think that an 80% removal would be helpful if other, more effective methods have lower throughput. So you could do bulk removal through this method, followed by further purification. This would be helpful if throughput is limited by the amount of contamination vs volume of water to purify.

I have a naturopathic doctor and I did a GI MAP test and I am doing herbal antimicrobials, diet modification, probiotics and supplements to heal the lining of my gut. So basically test / kill bad bacteria/ re populate with good bacteria and then heal gut lining.
