BAF attempts to prevent type-specific filter head Products; BAF dedicated backwash filter head is made of ABS plastic, composed of four parts by the filter cap, filter rods, embedded sleeves, anti-clogging filter caps, biological aerated filter Private pool backwash filter head total length of 355mm, filter backwash water supply than head length is longer filter plate reinforced concrete manufacturing, both of which need to be applied with the biofilter. Attempts to prevent type-specific filter head BAF BAF technical requirements ⑴ special blockades type filter head with filter cap from the filter rod, and attempts to prevent the filter cap sleeves embedded composition, embedded in the casing embedded in concrete Plates and internally threaded, filtration plate thickness 100mm. (2) filter head, filter tubes and embedded casing properties are consistent with the provisions of "drinking water compared with standard equipment and safety evaluation of protective materials" GB / T 17219's. (3) high pressure filter head promise, stepped touch is not broken, securely connected skillet filter head technical parameters, after installation shall ensure that the filter head does not fall off. (4) between the filter head and filter plate should be no dead zones, do not plug the plot mud. (5) skillet filter head quality inspection standards; filter head gap should be no defects, fly edges and burrs, filter head surface should be smooth, no impurities, no cracks Brachypodium Plates filter head, no bubbles, consistent surface color , James shiny surface, the product without flexing phenomenon, no shrinkage, no less than material phenomenon. According to specifications, is not greater than ± 0.1mm. (6) filter head tensile strength of 35 ~ 45Mpa soda backwash filter head, the impact strength of 9 ~ 30KJ / m2, Shore A hardness of 98 to 108. (7) pure gas backwash, water and air filter head loss, while the head of the filter backwash head head loss should meet the design requirements. Filter head (filter cap) is to filter the water treatment process is an important aspect of running water treatment filter, the filter layer interception with increasing amounts of sludge deeper penetration, resulting in decreased filtration rate, filter the water level gradually rise, filtered water turbidity increases. In order to filter back to normal operation, to ensure water quality and quantity, then must recoil - backwash process water from the bottom of the filter plate, the impact on the filter plate filter layer. As the traditional filter technology obsolete, energy water consumption, backwash high cost, poor, and thus filter design has been widely used in today's small resistance of the water distribution system filter head, Plates air and water backwash process. Filter head, Plates water distribution system has simple structure, reliable technology, small head loss, low energy consumption, no dead zones, mud clogging the plot, easy construction management and a series of advantages. BAF filter head Detailed Synopsis: BAF filter head is a special process components, in recent years, have been widely used in waterworks. In BAF process, filter head is mounted on the filter plate for water distribution and backwash; BAF technology in applications, but also to cancel the aeration system uses a single set of filter head aeration oxygen in the water at the same time the Examples of projects. BAF filter head by injection molding from ABS plastic, high strength, no rust, acid corrosion. The main components of the filter head filter rod filter head, filter cap and embedded parts (nut casing), inter-thread connection with enhanced firmly not fall off; the use of rubber rings, so good sealing; filter cap design bearing strength high resistance to tread touch. Orange filter head structure is simple, easy to install, wall smooth, no dead zones, no accumulation of sludge. When compared to traditional filter backwash water saving more than half. Skillet filter head size, LINQing filter head, Song Xin filter filter head is provided by Gongyi City Song Xin Industrial Co. filter.
