Product Description

What Are Sand Filters?
Sand filters are constructed beds of sand or other suitable granular material usually two to three feet deep. The filter materials (called media) are contained in a liner made of concrete, plastic, or other impermeable material. Depending on the design, the filter may be situated above ground, partially above ground, or below ground, and the filter surface may be single pass or covered. If covered, it should be vented to maintain aerobic conditions.
Partially treated wastewater is applied to the filter surface in intermittent doses and receives treatment as it slowly trickles through the media. The wastewater then collects in an under-drain and flows to further treatment and/or disposal. The pipes, pumps, and valves can be purchased commercially in a kit.
Sand filter units are constructed or assembled onsite by a contractor. Most materials are available locally, sometimes with the exception of filter media. If the appropriate media cannot be obtained nearby, it must be shipped in, which can greatly increase the filter's cost.
Suitable filter media can be purchased from aggregate companies or other suppliers. The media must be as clean and uniform in size as possible to allow the wastewater to flow correctly through it. If not, smaller grains will settle in the spaces between the larger grains, leaving no place for the wastewater to flow.
There are several different sand filter types and designs. Some are better suited for small communities, clusters of homes, large businesses, or institutions, while others are more appropriate for individual homes and small businesses.
Why Consider Sand Filters?

• Sand filters cost less to construct in rural areas than centralized treatment systems.
• They are energy-efficient
• They have relatively low maintenance requirements but should be serviced by trained technicians.
• They can provide high quality effluent.
• Sand filters may enable development in difficult sites.
• They can remedy an existing malfunctioning system.
• They can be a good option for homes in environmentally sensitive areas.
