AI Technical Summary
Existing water treatment filters are ineffective at removing heavy metals and microorganisms, especially bacteria, and have problems with insufficient permeability and tensile strength.
A multi-layer water treatment filter is formed by using a filter layer containing two types of nanocellulose lyocell fiber and bamboo fiber with different degrees of freeness and average fiber length, combined with zirconium hydroxide adsorbent and powdered activated carbon. The filter performance is improved through the design of lamination and adhesive layers.
It achieves the ability to efficiently remove heavy metals and microorganisms, while possessing excellent tensile strength and high water permeability, ensuring that the filter is not easily broken or deformed during use, achieving a removal efficiency of 99.99% for E. coli, 99.9% for particles, and over 90% for heavy metals.
