In fact, the so-called sand filter is usually said quartz sand filter, this device is carried out through quartz sand bed filter carrier depth filtration, usually for a filtration system. Filter equipment, this equipment for the treated water org anic impurities and inorganic impurities are most effective, and the ability to filter out and intercept impurities strong, uninterrupted water supply, so use very convenient.dust filter
1, gravel filters work
In the normal operating state, have not been filtered sewage from the upper portion of the device into the internal uniform under pressure through the filter, and then pooled into the bottom of the device, the clean water is then pooled to a dry tube fed irrigation systems . In the overall design of this equipment, it is necessary to do the water evenly spread in the filter, from the bottom of the catchment device collection, to prohibit water only after filter from the local, affecting the filtering effect.
2, gravel filters recoil
When the device requires flushing, other filtered clean water flows from the bottom of the device, reverse through the filter, so that the pore expansion in the filter after th e rapid expansion, so that the remaining impurities in the intra-equipment recoil out. The recoil traffic must meet the appropriate pressure, but at the same time pressure can not filter with the equipment, so we need to install a valve on the outfall is mainly used for the control and regulation of the flow of the recoil.
Reverse flow at the bottom of the water flow from the device when the device is in the backwash state, circulating water in which to render movement, so there may be a small amount of impurities were taken to the bottom of the device and left. When the water supply of equipment to the normal state when, in order to prevent contaminants from entering the entire system, we should be downstream of the sand filter before installing a comb or laminated filter, to ensure the safe operation of the system.
