Maintenance of the Aqua-Filter™ Stormwater Filtration System is two-fold. First, inspect the swirl concentrator, then inspect the filtration chamber.
The first step is to inspect and cleanout the Swirl Concentrator pre-treatment chamber. Free-floating oil and floatable debris can be directly observed and removed through the 32-inch service access provided. If cleanout is needed, a vacuum truck can be used to remove the accumulated sediment and debris.
The second step is to inspect and cleanout the Aqua-Filter™ filtration chamber. Inspection of the filtration chambers can be performed from the surface by observing the color change of the filter media from its original light color to dark brown. If the filter bags need replacing, entry into the system is required. The spent filter containers are lifted from the chamber as shown below.
Replacement filters are then lowered into the system and set into position. The filters are placed into two foot by two foot holders that should be overlapped such that the lower two bags are parallel to the length of the filtration chamber, and the upper two are perpendicular to the length of the chamber. Care must be taken to ensure that the containers are seated into position to promote good contact with the walls on all sides.
Typically, the spent filters do not require any special treatment or handling for disposal. AquaShield™ recommends that all materials removed be handled and disposed of in accordance with local and state requirements.
An Inspection and Maintenance Manual is provided with the Aqua-Filter™ system for more detailed maintenance procedures.
The Aqua-Filter™ system has been designed and fabricated to facilitate easy installation of the system.
