How Does Water Filtration Remove Heavy Metals From Water? 

Water is a necessity of life, but the water we consume on a daily basis can be loaded with heavy metals. These toxic substances can be found in tap water or contaminated groundwater and can cause serious health problems over time if not treated properly.

The best way to protect yourself against the risk of consuming harmful chemicals is to filter your drinking water. A good quality water filter will remove a wide range of contaminants, including heavy metals. 

How does water filtration remove heavy metals?

A water filtration system removes harmful elements by allowing only the dissolved molecules to pass through. The most effective heavy metals removal systems use multiple stages of filtration to ensure that only clean, healthy water is delivered to your home. 

KDF filters and ceramic filters are two popular options for removing heavy metals from your tap water. These filters work by using an oxidation/reduction reaction to reduce copper, lead, nickel, chromium, and mercury. 

Another common method of reducing heavy metals in your water is the use of an ion exchange resin. This method works by attracting the heavy metal ions in your water to the ion exchange resin surface and swapping them for harmless ions like chloride. 

Researchers have discovered that proteins from vegetable oil production can attract heavy metal ions and help purify contaminated water. They believe that this ion exchange process could be used in industrial settings to clean water produced by mining or drilling, and it requires little or no power. 

Reverse osmosis is another effective filtration technique for removing heavy metals from your drinking water. It can treat cadmium, copper, lead, and arsenic. 

In some instances, the minerals that contain these heavy metals can also be recovered for other purposes, such as processing semiconductors or pharmaceuticals. But most current methods of removing these minerals are energy-intensive and require a lot of electricity to operate. 

Alternatively, researchers have developed a new membrane that can absorb toxic elements from contaminated water. The membrane is made from a waste product of vegetable oil manufacturing, and the proteins that are a byproduct of peanut or sunflower oil production can easily attract the heavy metal ions in the water. 

This new membrane is a more sustainable and economical way to clean contaminated water than currently available processes, the researchers say. This method also requires less energy and can be more selective in what it filters.
