Limited Quantity Alert: Discover Pyrolox®, the renowned granular water filtration media trusted for over 75 years for its exceptional removal of hydrogen sulfide, iron, and manganese. Mined naturally, Pyrolox leverages a unique chemical reaction to produce pristine, high-quality water effortlessly. Its oxidation process effectively eliminates iron, manganese, and hydrogen sulfide from problematic water, while trapped particulates are purged during the backwash cycle. To ensure sustained performance and enhanced removal capacity, a recommended oxidant feed is advised, such as chlorine injection (options include chlorine, sodium hypochlorite, or calcium hypochlorite) upstream of the filter feed. Other acceptable oxidants include air injection, potassium permanganate, sodium permanganate, etc., with the exception of hydrogen peroxide. Proper backwashing is crucial for Pyrolox media, ensuring optimal bed expansion and prolonged service life. For peak performance, install Pyrolox with an underbed and backwash daily, though individual application requirements may vary. Act fast to secure yours while stocks last!
