The UltraTech 9461 PhosFilter Media Filter Bag is a replacement filter media bag designed for use in the Ultra-HydroKleen catch basin filtration system, specifically targeting the removal of phosphorous from stormwater and industrial runoff. The HydroKleen filter chamber holds up to three media bags simultaneously, allowing the PhosFilter bag to be combined with Sorb-44 (Part #9462) and Activated Carbon (Part #9463) bags to create a multi-pollutant treatment configuration tailored to site-specific stormwater management requirements. UltraTech recommends replacing filter media bags every six months as a general maintenance guideline, though replacement frequency will vary based on local conditions and contaminant loading.
