Hi.
I need to remove all microplastics of a wastewater sample without changing any physicochemical properties of the sample.
Can filtration by Whatman filters (for example Whatman 589/3 with particle retention liquid less than 2 micron) remove all microplastics?
Hi Masha, that's a great question! Microplastics are a growing concern, and effective filtration is essential for their removal.
Whatman Filters:
- Whatman filters are widely used in laboratory settings for various filtration tasks.
- The Whatman 589/3 filter you mentioned has a particle retention size of less than 2 microns.
- While it can capture many small particles, including some microplastics, it might not remove all due to the variability in microplastic size. Microplastics Removal:
- To effectively remove microplastics from wastewater without altering physicochemical properties, consider the following options:
- Reverse Osmosis (RO) Filters are highly effective for removing microplastics. RO filters use a semi-permeable membrane that can filter down to 0.001 microns, removing all known microplastics.
- Carbon Block Faucet Filters: Some efficient models, such as the TAPP 2, can remove 100% of all known microplastics.
- Ceramic Filters: These can remove up to 99.99% of microplastics Considerations:
- When choosing a filtration method, consider factors such as flow rate, maintenance requirements, and overall value for money.
- Ensure that the selected filter meets your specific needs and provides the desired level of microplastic removal.
While the Whatman filter you mentioned may capture some microplastics, I recommend exploring more specialized options like reverse osmosis or ceramic filters for comprehensive removal.
Filtration, regardless of the method, will change the water's properties. In addition to microplastics, there will be other suspended substances in wastewater. Both organic and inorganic. Glass fiber filter for example Whatman GF. They are available in different retention values. For example, GF/C has 1.2 µm. Fiberglass filters can be ignited, so that they become free of organic matter. Before use.
