    There are not many domestic filter brick manufacturers, and the filter bricks look similar in appearance, but the difference is quite big when actually used. One is the shell material, most manufacturers only use it as a mold, in fact, the shell is also very important.

    The second is the material of internal filling, many manufacturers just pour a little concrete and don't care, neither vibrating and compacting nor maintenance, resulting in poor strength, and even using C20C25 low-grade concrete.

    The third is the setting of the air pipe, now some manufacturers of the air pipe inlet is from the side of the air intake, so that when the backwash, the front end of the gas is sufficient, and the back end is insufficient. There are even some manufacturers whose bronchial tubes are not covered with pools and are broken.

    The fourth is the fixation of the cloth air pipe, some manufacturers do not fix, some manufacturers use plastic buckles, which are not appropriate, and will swing and damage the connection parts after a long time.

    I have a few factories here with Guizhou Shuaiyi environmental protection filter bricks, the use of the feeling is still good, compared with some other water plant filter bricks in terms of workmanship quality and effect are better, ** is also cheaper.

    The denitrification deep bed filter is a mature technology in foreign countries for many years, and the basic domestic promotion is De Nora Xylem and South Korea DI three, and the patent is mainly for the filter brick cloth water distribution and gas part. Recently, there are more and more domestic sewage treatment plant upgrading projects, deep bed filter is the safest last process, which can not only produce total nitrogen, but also remove ss, and there are more and more domestic manufacturers of this kind of equipment, but there are not many experienced source manufacturers who can really do a good job.

    Let me tell you:

    Deep bed filter + carbon source dosing + denitrification filter control technology = deep bed denitrification filter.

    The deep bed denitrification filter is a set of processes, and the equipment includes: filter civil engineering, filter bricks, graded supporting layer, coarse-grained quartz sand filter material, water distribution weir plate, valve, recoil pump, recoil fan, water quality testing instrument, liquid level gauge, flow meter, carbon source storage and dosing system, control system, pipeline, cable and installation accessories, etc.

    The post-denitrification process is more suitable for the following applications:

    A. Wastewater with significantly low BOD5 content (high proportion of industrial wastewater).

    b. For the transformation and upgrading of sewage plants, the nitrification index was not considered before, and the effluent BOD5 was low, but the ammonia nitrogen was high.

    I know, so you know!

    In contrast, an up-flow denitrified deep-bed filter is better.
