Microplastics — plastic pieces smaller than one-fifth of an inch — are now found in almost all Oceans and marine animals. What’s worse, sea salt has been found to have considerable amounts of microplastic.
The researchers claimed that while there have been many studies to identify and quantify microplastics in various food products, including salt, there have been fewer attempts at finding ways to remove them.
Hollow fibre membranes are already used extensively in daily life applications such as RO pre-treatment, industrial water or waste water, juice processing, and other biotech applications, including in dialysis membranes used for kidney ailments.
