Product Specification
Lanlang ® TA306D is a high-quality anion exchange resin that features hydrous iron oxide nanoparticles and a polystyrene matrix in a standard Gaussian size distribution. This innovative formula is specifically designed for the efficient removal of arsenate and arsenite, as it uses a two-step process to capture and adsorb the harmful contaminants. The resin's fast kinetics are impressive, as they allow for the removal of arsenic content to less than 10ppb. With TA306D, users can trust that they are investing in a reliable and effective product that prioritizes water safety and purity.
Chromium is a tasteless, odorless metal that occurs naturally in rocks, soil, and animals. It manifests in two forms, one that the human body needs and one that is toxic. The healthy form of chromium, known as trivalent chromium or chromium-3, is vital in maintaining blood sugar levels. The other type of chromium, called hexavalent chromium or chromium-6, is a carcinogen that can cause long-term health problems. Both forms of chromium can reside together, and they can even switch between forms when acted upon by outside factors. Because of the toxicity of hexavalent chromium, its presence in water supplies must be limited to prevent adverse side effects.
Hexavalent chromium enters well water from the erosion of rocks underground. It is most abundant in the Piedmont region of the eastern United States. This area includes Georgia, the Carolinas, Virginia, Maryland, Pennsylvania, and New Jersey. Some capacity of chromium-6 can also be found in every state outside the Piedmont region. High levels of hexavalent chromium have been found in water supplies in states like Oklahoma, Wisconsin, and even Hawaii. Regardless of location, you should test for hexavalent chromium in your well water before utilizing it for drinking or cooking.
