    稀土瓷砂滤料潘加了稀土改性剂,采用科学配方,经专门成形和高温烧制而成,与传统的石英砂和无烟煤滤料相比,

    具有以下优点:

    1、球形表面,空隙率大,滤速一般为15~20m狮,床层水头损失小,可以降低滤池高度,节省电耗和基建费用;

    2、颗粒均匀规整,易清洗,反冲洗强度一般为12~20/rrfS反冲洗的耗水量可减少30~50%;

    3、孔容大,比表面积大,截污量大,一般为9~10 kg/m',是石英砂滤料的12N15倍,

    4、强度高,磨耗小,不会破损,使用寿命可达15年以上;

    5、耐腐蚀,不流失、无污染,无溶出有害物,保证水质稳定。

    稀土瓷砂滤料广泛用于滤池,机械过滤器中做过滤介质,有效处理各种进水和污水,还可用于烟气除尘器中做滤料,

    过滤除去各种工业粉尘和锅炉烟尘。

    Ceramic sand filters are doped with rare earth element and processed by mix,shaping and sintering.Compared with traditional sands and coal filter material,ceramic sand filters have great advantages as follows:

    1、Shaped in sphere,the ceramic filtier sand has a high void space,normally,its filtering velocity is 15-20 m3/h,less loss water-head,and suitable to reduce the height of filter bed and cut down the electric power and constructional expenses;

    2、Uniform and regular in particle size,make it easy to be cleaned,the back-flus strength is 12-20 l/m2.s;It can save the back-flush water more than 30-50%;

    3、High surface area,large poer volume,the ceramic sand filter is of great amount of pollutant entrapment,up to 9-10Kg/m3,about 1.2 to 1.5 times that quartz sand filter of 7.8-9Kg/m3;

    4、Great mechanical strength,less abrasion loss,and never be damaged,the ceramic sand filters can serve for a long life moer than 15 years,is the 5 times or longer than that of quartz sand filters;

    5、Corrosion resistant,no run-off and no harmful substance dissolved out,the ceramis sand filters can ensure the treated water in consistent quality without any secondary pollution may c aused by the filter as quartz sand or coal filters itself.
