What happens to old water filters after they are thrown away?
If you throw old water filters in the trash, they will end up with other trash in your household. Unfortunately, only a few recycling facilities will be able to recycle water filters, so they will likely end up in landfills.
And while most water filters contain no toxic chemicals that can harm the environment, their housing, and other interior parts are non-biodegradable and will remain in landfills for years to come.
What are water filters made of?
Most water filters have a filtering component (made of carbon, plastic, etc.) and are held together with a plastic or metal casing, depending on their manufacturer. For example, Brita water filters are made of polypropylene, while EverPure filters contain aluminum. This is why water filters are difficult to recycle because they require different recycling methods depending on their composition.
Clean and Reuse Old Water Filters
Reusing old water filters is one of the best things you can do. Depending on the type of water filter you use, cleaning and reusing them may be a viable option. There are many types of water filters. Here are some of the most commonly used.
1 Activated Carbon Water Filter System
Activated carbon, also known as activated carbon granules or AC, is the most commonly used home water filter. It is based on charcoal made by burning wood and other materials in a low oxygen supply. Activated carbon water filters are great for removing many common impurities in water, including chlorine-based chemicals, pesticides, and industrial solvents. However, it quickly gets clogged with impurities and must be changed regularly.
2 Reverse osmosis water filter system
You will need this type of water filter if your water contains arsenic or other dangerous compounds. Reverse Osmosis (RO) water filters effectively remove dissolved inorganic contaminants from water through a semipermeable membrane, and filter out everything larger than a water particle.
However, these types of water filters require electrically powered pumps to generate water pressure to force the water through the membrane, which costs money to run. And unfortunately, reverse osmosis systems generate a considerable amount of wastewater. Still, reverse osmosis is great at providing safe drinking water for your home.
3 Ion Exchange Water Filter System
Ion exchange filters are made with lots of zeolite beads that contain sodium ions. In Layman’s terms, zeolites are solid particles with a relatively open, three-dimensional crystal structure composed of the elements aluminum, oxygen and silicon, as well as molecules of alkali or alkaline-earth metals (such as sodium, potassium and magnesium) and water. There are ,
This type of water filter traps incoming magnesium and calcium ions, making the water taste softer and more pleasant. However, ion-exchange filtration needs to be periodically recharged with more sodium ions, usually by adding a special salt.
Knowing the water filter you are using will tell you whether you can reuse them. For starters, a water filter can be freshened up by using activated charcoal in some capacity. You can open the water filter cartridge and add fresh activated charcoal. Activated charcoal can be purchased or made by drying and processing coconut husks at high temperatures.
