Water contaminant reduction using coated adsorbent
A recently granted patent (Publication Number: US11944952B2) discloses a process for reducing contaminants, specifically selenium and arsenic, from contaminated water with a pH range of 2 to 12. The method involves utilizing a water-insoluble adsorbent with a minimum surface area of 10 m2/g, coated with a water-soluble metal salt, and then introducing this adsorbent to the contaminated water for treatment.
The patent outlines that the water-soluble salt used can be selected from ferric salts, aluminum salts, or a combination of both. Additionally, the weight percentage of the metal salt coated on the adsorbent should fall within the range of 0.1% to 1.4% by weight. The pH of the contaminated water is recommended to be between 4 and 9, with the coated adsorbent present in the water at a concentration level ranging from 0.5 to 20 g/liter. This innovative process offers a promising solution for effectively reducing selenium and arsenic contaminants in water sources, addressing a critical environmental and public health concern.
