Problem<\/h3>\n

Iron content and solid particles.<\/p>\n

Unit description<\/h3>\n

The chemical-free filter unit is designed to remove precipitated iron (Fe3+<\/sup>), drift sand and mechanical particles. The unit consists of a vessel filled with filter media and a fully automatic controller that manages the filter’s operation. The filter medium is quartz sand, made specifically for water treatment.<\/p>\n

Operating principle<\/h3>\n

The essence of the process of removing iron and other mechanical particles is filtering the precipitate into the filter media. The precipitate is captured and, during the backwashing of the filter media, is flushed into the drain. No chemicals are needed to backwash the unit’s filter media. The unit works fully automatically, backwashing on a time basis. Under the standard program, backwashing takes place every three days. The installation site needs an electrical outlet and a drain connection.<\/p>\n
