| Intermittent Sand Filter Packages |
Intermittent sand filters (ISFs) are capable of producing clear, clean effluent that meets the criteria for “advanced” wastewater treatment. As a result, ISFs can be a good solution for environmentally sensitive building sites, as long as there is sufficient land available (since the typical ISF footprint is 360 sq.ft.). To have a properly functioning ISF, the right type and size of sand media must be used, and the system must be properly installed. Orenco provides system designers with guidelines for media selection. And Orenco sells complete, carefully engineered ISF packages that come with a helpful installation video.
Orenco’s Intermittent Sand Filter Packages include the following:
• Pumping package
• Liner and accessories
• Filter fabric
• Manifold assembly
• Pump basin package (if required)
• Distributing valve (if required)
The individual components of an intermittent sand filter package are described in other parts of this catalog.
