Bipolar Nanoporous Compact Filter for Charged Particles Removal

Heavy metal pollution is a significant environmental issue with detrimental health effects even at low concentrations. The bipolar nanoporous membrane features a triple-layer structure, comprising a membrane base layer, a selective layer, and a protective layer.

This technology relates to a compact, bipolar nanoporous membrane that effectively removes dissolved heavy metal ions from industrial wastewater and drinking water. This configuration allows the membrane to efficiently adsorb and reject charged pollutants and heavy metal ions while minimizing fouling through its antifouling properties.

To implement this technology, a portable water filtration bottle has been specifically designed, fabricated, and evaluated. The filtration bottle incorporates a single-stage bipolar nanoporous membrane module, serving as a reusable filter. The technology demonstrates rejection rates (>95%) for divalent and trivalent heavy metal ions such as Arsenic (As), Copper (Cu²⁺), Cadmium (Cd²⁺), Lead (Pb²⁺), and Chromium (Cr³⁺) at concentrations ranging from 20 ppm to 100 ppm.

The compact and low-pressure nature of this technology makes it highly versatile and suitable for various applications. It offers a convenient and reusable filtration solution for industrial wastewater treatment and the purification of drinking water. By effectively addressing the challenge of heavy metal pollution, this technology contributes to environmental protection and safeguarding human health.

Overall, this advanced water filtration solution combines the advantages of a bipolar nanoporous membrane and a portable filtration system. Its exceptional rejection capabilities, energy efficiency, and versatility make it a promising tool in mitigating heavy metal contamination and ensuring access to clean and safe water.
