ABSTRACT

Zinc and chromium are two heavy metals that are commonly found in stream-sourced water. These metals can be harmful to human health, and they can also cause environmental damage. This study investigated the removal of zinc and chromium from stream-sourced water using a kaolin-based nanomembrane filter. The filter was able to remove up to 50% of zinc and chromium from the water, making it a promising new technology for sustainable water treatment. The kaolin- based nanomembrane filter is made from a naturally occurring clay mineral that has been modified to create a nanoporous structure. This structure allows the filter to selectively remove zinc and chromium from the water, while allowing other essential minerals to pass through. The filter is also relatively inexpensive to produce and easy to maintain, making it a sustainable and cost-effective option for water treatment. The results of this study demonstrate the potential of kaolin-based nanomembrane filters for the removal of zinc and chromium from stream-sourced water. This technology could be used to improve the quality of drinking water and to protect the environment from the harmful effects of these heavy metals.
