Which water treatment systems are safe to use?

The Verge’s Chris Kohler has written about water treatment technologies and their benefits, including the health risks associated with the chemicals used to purify water.

But he’s also written about the issues surrounding water treatment technology.

As a recent TechCrunch article notes, the FDA’s review process can be a little haphazard, especially for systems that rely on filtration systems.

For example, a recent FDA report on bioremediations, which can be used to remove pollutants from wastewater and wastewater treatment plants, noted that “there are few studies to validate these technologies.”

In response to this, the Institute of Medicine’s American Water Works Association released a report in 2015 that stated “the bioremediate approach is unlikely to be successful in reducing greenhouse gas emissions, especially because bioremineralization can remove most, if not all, of the CO2 produced by sewage treatment plants.”

While biorefineries are a more recent development, they’ve been used for decades.

Today, they’re still a big part of the water treatment process, even though their use is declining.

In fact, the amount of energy they consume is increasing, and in some countries they’re also becoming more expensive.

Here are 10 of the most popular water treatment processes, and how they work.


Pure water: A pure water treatment method uses a process called precipitation to purification.

This process relies on precipitation from a stream to remove contaminants.

This type of water treatment has been around for decades, but the FDA found that it’s less effective than filtrating systems because the water is less concentrated.


Hydrochloric acid: A hydrochloric solution, which is used to dissolve dissolved pollutants in water, is commonly used in water treatment.

In the past, hydrochlorics were used to treat sewage, but they were often toxic.

In recent years, they have been used to clean sewage water.


H2O: A water treatment solution used to kill bacteria, viruses, and other organisms in the environment is sometimes referred to as “organic matter.”

This type is typically produced from anaerobic bacteria, and is also a waste product.


Hydrofluoric acid: Hydrofluorocarbons are a type of organic matter used in natural gas production.

They are produced by microbes in the atmosphere and are used to cool and filter gas.


Nitric acid: Nitric acids are chemicals that are produced in natural oil refining and are also used in many natural gas and coal processing plants.


Brominated vegetable terephthalate: This chemical is used as a paint remover, and its use is also increasing in other industries.

It’s used in automotive paint and other products, but also in the production of pharmaceuticals.


Bismuth oxychloride: This toxic chemical is often used in the manufacturing of paper and plastics.

It is also used as an additive in the manufacture of paint.


Propylene glycol: This substance is used in rubber, and it’s used to make plastics.


Sulfur dioxide: This compound is often sprayed on wood, paper, and wood products, and also used to produce synthetic rubber.


Phthalates: This type, also known as phthalates, are chemicals used in plastic and metal manufacturing that have been linked to developmental delays and learning disabilities in children.
