We have a sand filter system that uses a timer to dose the entire surface of the filter
intermittently with wastewater. This system draws oxygen from the atmosphere through
the sand medium area. Physical, chemical and biological processes are ways the effluent
is treated within the system. The treatment occurs through the bacteria that colonize in
the sand grains of the sand filter system. The microorganisms use the organic matter in
the effluent for growth and reproduction to help continually maintain the system
properly.
