Users can maintain flow rate by cleaning the filter through agitating the top level of sand, or by pretreating turbid water before filtration. Lab Effectiveness, Field Effectiveness, and Health Impact. Slow sand filter lab effectiveness studies with a mature biolayer have shown % protozoan, 9099% bacterial, and variable viral reduction.
and carried along with the flow. This phenomenon is known as sand production. Sand production is one of the oldest problems of oil fields. It is usually associated with shallow formations as compaction tends to increase with depth but in some formations, sand production may be encountered to a depth of 12000ft or more.

The sand and gravel settles out of the water and form the river bed. As the river channel moves across the landscape, the sand and gravel (aggregate) deposits are left behind. In the Platte River valley, these deposits can be greater than 150 feet deep and often contain mammoth bones and teeth, bison bones and petrified wood.
2 As a production run starts, the required amounts of sand, gravel, and cement are transferred by gravity or by mechanical means to a weigh batcher which measures the proper amounts of each material. 3 The dry materials then flow into a stationary mixer where they are blended together for several minutes.
Sand causes a wide variety of costly problems when oil and gas are produced from unconsolidated reservoirs. The most costly problem is usually the loss of production resulting from formation damage caused by poorly planned and/or executed sand control applications.
