The patented Aqua-Guardian™ Catch Basin Insert is a post-construction flow-through water quality device custom designed to effectively remove sediment, trash & debris, heavy metals bound to particulate matter and oil. The Aqua-Guardian™ captures gross pollutants while simultaneously providing a high level of filtration treatment of stormwater runoff or industrial water discharges. The Aqua-Guardian™ uses the same types of filter media that are also used in the Aqua-Filter™ Stormwater Filtration System.
The most commonly used media in the Aqua-Guardian™ and Aqua-Filter™ is perlite. Other filter media such as granular activated carbon (GAC), leaf compost, zeolite and various media blends are also available for the Aqua-Guardian™ to meet site-specific discharge criteria. Implementing a consistent maintenance program will result in long term operational and performance efficiency for the Aqua-Guardian™ insert.
