How Effective is Reverse Osmosis Filtration?

Could the reverse-osmosis purified water I’m using for cooking and enemas be a source of heavy metals (particularly Thallium)? Does reverse-osmosis filtration remove heavy metals?

Reverse osmosis (RO) filtration is generally one of the most effective methods for removing a wide range of contaminants, including heavy metals, from water. Here’s how it works and its effectiveness regarding heavy metals, such as thallium:

How Reverse Osmosis Works

Reverse osmosis filters force water through a semi-permeable membrane, which allows water molecules to pass through but blocks many impurities, including dissolved salts, chemicals, and heavy metals.

Heavy Metal Removal by Reverse Osmosis

RO systems are highly effective at removing many heavy metals, including:

• Lead

• Mercury

• Cadmium

• Chromium

• Arsenic

• Thallium

• Copper

• Iron

• Zinc

In general, reverse osmosis filtration can reduce the concentration of heavy metals by 90% to 99%, depending on the system’s efficiency, maintenance, and water quality.

Does Reverse Osmosis Remove Thallium?

Yes, reverse osmosis filtration is capable of removing thallium, a toxic heavy metal, from water. Thallium contamination is relatively rare, but if present in water sources, an RO system should effectively reduce it to safe levels.

Possible Concerns with Reverse Osmosis

1. Membrane Maintenance:

   • RO systems require regular maintenance, including replacing the membrane and filters. If these are not properly maintained, the system’s efficiency in removing contaminants, including heavy metals, may decrease.

2. Water Source:

   • If your water source has unusually high levels of certain contaminants, including heavy metals, it’s important to regularly test the filtered water to ensure your RO system is working as expected.

3. Mineral Deficiency:

   • RO filters remove not only harmful substances but also beneficial minerals like calcium and magnesium. For drinking water, it may be a good idea to remineralize the water or use an additional filter that adds healthy minerals back in.

Can Reverse Osmosis Water Still Contain Contaminants?

If your reverse osmosis system is functioning properly, it should not be a source of heavy metals like thallium. However, if the system is old or improperly maintained, or if there’s a defect in the membrane, contaminants could theoretically bypass the filter.

Recommendations:

• Test Your Water: If you’re concerned about heavy metal contamination, it’s wise to have both your tap water and RO-filtered water tested for heavy metals, including thallium.

• Regular Maintenance: Make sure to regularly replace the RO filters and membrane according to the manufacturer’s guidelines.

• Remineralization: Consider using a remineralization filter for your drinking water to ensure you’re getting necessary minerals.

In summary, reverse osmosis is highly effective at removing heavy metals, including thallium, but regular maintenance and testing are essential to ensure it is functioning properly.
