The equipment is suitable for the requirements of the filtered water turbidity generally 5 mg / liter or less, to meet the drinking water standards of industrial water or domestic water treatment equipment to industrial and mining towns. Water contains suspended solids, agglomeration of flakes, sand, iron, manganese, and can not be removed by precipitation method of bonding colloidal particles, etc., through the filter layer packed in the pressure filter, the water reached transparent. Industrial wastewater suspended solids, solids removal, also have a good effect. This product is divided into two water cases options: single-layer filter media often applies to water turbidity at 100 mg / l, without coagulation and sedimentation of raw water (such as frequent with higher raw water turbidity, should Note operating cycle is shortened or decreased filtration rate), this filter should be used in front of the coagulant. Dual media filter applied to water turbidity is generally 15 mg / liter, the maximum not more than 20 mg / l of precipitation water. The device according to the filter media separation are: quartz sand filters, activated carbon filters, fiber ball filters.
