Classification of quartz sand filters

Quartz sand filters are generally classified into two types: one is conventional quartz sand filters, also known as shallow media filters. The other type is the emerging filter, called continuous sand filter, also known as flow sand filter. It differs from conventional sand filters in that it cleverly separates the filtration and sand washing processes at different locations, without the need for a clean water tank or a high-power backwash water pump, allowing for continuous and stable filtration operation.
