      稀土瓷砂濾料潘加了稀土改性劑,采用科學配方,經專門成形和高溫燒制而成,與傳統的石英砂和無煙煤濾料相比,

      具有以下優點:

      1、球形表面,空隙率大,濾速一般為15~20m獅,床層水頭損失小,可以降低濾池高度,節省電耗和基建費用;

      2、顆粒均勻規整,易清洗,反沖洗強度一般為12~20/rrfS反沖洗的耗水量可減少30~50%;

      3、孔容大,比表面積大,截污量大,一般為9~10 kg/m',是石英砂濾料的12N15倍,

      4、強度高,磨耗小,不會破損,使用壽命可達15年以上;

      5、耐腐蝕,不流失、無污染,無溶出有害物,保證水質穩定。

      稀土瓷砂濾料廣泛用于濾池,機械過濾器中做過濾介質,有效處理各種進水和污水,還可用于煙氣除塵器中做濾料,

      過濾除去各種工業粉塵和鍋爐煙塵。

      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.
