BAF attempts to prevent type-specific filter head Products; BAF dedicated backwash filter head is made of ABS plastic, composed of four parts by a filter cap, filter rod, embedded sleeves, anti-clogging filter caps, biological aerated filter Private pool backwash filter head total length of 355mm, filter backwash water than the average head length is longer, the filter plate reinforced concrete manufacturing, both of which need to be applied with the biofilter. BAF attempts to prevent type-specific technical requirements ⑴ filter head BAF special attempts to prevent type filter head with a filter from the filter rod cap, embedded casing and attempts to prevent the filter cap composition, embedded in the casing embedded in concrete Plates and internally threaded, filter plate thickness 100mm. (2) filter head, filter tubes and embedded casing properties are in line with the provisions of the "drinking water than the water distribution equipment and protective materials, safety evaluation criteria of" GB / T 17219 of. (3) high pressure filter head promise, step touch is not broken, reliable connection, after installation should ensure that the filter head does not fall off. (4) between the filter head and filter plate should be no dead zones, without clogging the plot mud. (5) skillet filter head quality standards; filter head gap should be no defects, burrs and burrs, filter head surface should be smooth, no impurities, no crack soda backwash filter head, no bubbles, uniform surface color, James shiny surface, the product without flexing phenomenon, no shrinkage filter head, no lack of material phenomenon. According to the specifications, not more than ± 0.1mm. (6) a tensile strength of filter head 35 ~ 45Mpa, the impact strength of 9 ~ 30KJ / m2, 98 to 108 Shore hardness. (7) pure pyramid filter head with air filter cap, head filter head loss and gas water backwash filter backwash simultaneously head head loss should meet the design requirements. Even opened a careful process of long slit on the filter head of the filter cap arc, both to prevent leakage of media, but also to ensure a uniform distribution of gas and water distribution. Filter rod is a plastic tube top opened a small hole near the bottom have two intake slit, compressed air into the space below the filter plate, the slow air layer is formed, and gradually thickens the air layer below the water continues drops until the water drops lower portion of the elongated filter rod skillet backwash filter head crack at the intake, when the air begins to flow from the crack hole filter rod. When the flow of air traffic into and through the filter cap gap equal flow stream flow away, the water will be stopped falling, stable at a predetermined position, the incoming air through the filter rod rises through the filter cap to the filter layer slit jet to go, due to cross multiple filter head ejection uniform distribution of backwash achieve good results. Note :( general, as the backwash water sump to clear, to stop the backwash water to control and reduce the unnecessary loss recoil). Air-water backwashing filter applied skillet filter head backwash air and water distribution systems; glandulifera filter head applies a single filter backwash water and gravity, pressure filter tank and ion exchange filter bed with water filtration system. Filter head can apply to drinking water treatment, also applicable to beverage, printing, and other industrial water at the swimming pool can also be used in industrial wastewater, sewage treatment project.
