Sand/Gravel Filter On-Site Sewage Facilities (OSSF)

Sand and gravel have been used in media filters for decades. Sand, a sand filter produces a very high quality effluent. Sand filters are beds of sand or gravel, drained from underneath so that primary treated effluent can be treated, collected, and distributed to the soil absorption field.

sand supported by graded gravel underlays. Wastewater effluent is passed through this sand layer before either percolating into the ground or being collected for disposal elsewhere. With appropriate adjustments to the loading rate a filter can be used for either 'secondary1 treatment of wastewater which has been through a sedimentation process (septic tank, Imhoff tank or other settling tank

are placed in a bed filled with gravel on top of the sand. The effluent leaves the pipes, trickles down through the gravel, and is treated as it filters through the sand. A gravel under-drain collects and moves the treated wastewater to either a second pump chamber for discharge to a pressurized distribu- tion system or to a gravity flow soil absorption field. The second pump chamber may be

Washington, D.C. September 1999 Wastewater Technology Fact

Sand is a commonly used medium, but anthracite, mineral tailings, bottom ash, etc., have also been used. The surface of the bed is intermittently dosed with effluent that percolates in a single pass through the sand to the bottom of the filter.

11.19.1 Sand And Gravel Processing

The scrubbed sand or gravel is diluted with water to 25 to 30 percent solids and is pumped to a set of cyclones for further desliming. If the deslimed sand or gravel contains mica, feldspar, and iron bearing minerals, it enters a froth flotation process to which sodium silicate and sulfuric acid are added.

Pharmaceuticals in on-site sewage effluent and ground

Three of the 12 compounds, carbamazepine, sulfamethoxazole, and nicotine, were detected in the underlying sand and gravel aquifer after effluent percolation through a 2.0-m thick sand vadose zone. Sampling of a second sand, gravel, and cobble dominated unconfined aquifer, partially overlain by septic systems and a city sewer system, revealed the presence of caffeine, carbamazepine, cotinine

Aquifer media gravels are often coated by iron and manganese oxides (Hinton and Close, 1998), and the positively charged metal oxide patches could adsorb the negatively charged DNA
