Potable or drinking water, point-of-use filtration systems, arsenic remediation, water treatment plants, pharmaceutical or analytical laboratories, etc.
Inventors at University of Wisconsin-Milwaukee have developed ceramic filtration material with Lanthanum (La) coating that effectively removes water contaminants for safer drinking water. Porous ceramic materials are prepared with the use of earth abundant clay minerals as substrates and organic wastes (recycled cellulose fibers) as pore forming materials and can be fabricated into various shapes for the desired filtration method. The filtration media utilizes high affinity of lanthanum for arsenic and chromium removal, and tunable porosity of ceramic materials for bacterial and virus removal at desired flow rates.
