产品说明
     箱式生物过滤器是循环水处理诸多环节中的核心设备。在循环水体总
水量固定的情况下，投入的总氮量不断增加，
这些含氮物质在一系列的生物的作用下，转化成溶解于水的氨或亚硝酸盐类
，这些物质的不断积累，将导致水生生物的中毒。
故在循环水养殖中必须将这些氨氮等物质转化为无毒的物质。生化箱就是通过
一定的载体，培育生化细菌，
对水中的氨氮等物质进行分解。但生化过滤需要一定的前置预处理，如过滤沙缸
、蛋白质分离器等都可作为生物过滤的预处理设备。
工作原理
    箱式生物过滤器（生物过滤箱）是蓝灵水族在一系列的海水循环水养殖中不
断总结经验而生产的一种生物过滤容器，
它精巧的设计让水流始终保持在一定的流速范围内，保证了生物膜能尽快地在
生物滤料上附着，从而与整个系统设备一起发挥出最给力的效果。
组合设备
    过滤沙缸、蛋白质分离器、增氧泵或风机
注意事项
     箱式生物过滤器（生物过滤箱）不建议与臭氧发生器同时在循环水处理使
用，因水中的残余臭氧可导致有益菌被杀死，
从而使生化过滤失效。但可前置紫外线杀菌器。
     在可能的情况下，水流保持缓慢及保证高溶氧十分重要！ 
     在生物过器前端加装物理过滤设备如蛋白质分离器、微滤机等，可有效减
少箱式生物过滤器的清洗频率。


材料组成


无毒食品级PP或PVC，无析出，耐海水腐蚀。长期使用无需更换。


包含滤料均为超高比表面积的生物滤料，如毛刷、生化毡、珊瑚砂、多孔陶环、生物球等。
Product description


    tank type biological filter is the core equipment in many aspects of
 circulating water treatment. In the case of the water circulating water 
is fixed, the total nitrogen inputs are constantly increasing, these
 nitrogenous substances in a series of biological effects, transformed into
 water soluble ammonia or nitrites, the accumulation of these substances 
will cause aquatic poisoning. Therefore, it is necessary to convert these
 ammonia nitrogen and other substances into non-toxic substances in the 
circulating water culture. Biochemical tank is through a certain carrier,
 the cultivation of biological bacteria, ammonia nitrogen and other substances
 in the water decomposition. However, biochemical filtration requires a certain
 pre treatment, such as filter sand filter, protein skimmer, and so on.
Working principle
 
    Tank type biological filter (biological filter box) is a kind of biological
 filtration container in recirculating aquaculture a series of constantly sum
 up experience and production, its exquisite design and let the water remain
 at a certain velocity range, ensure the biofilm attached to the biological 
filter as soon as possible, and thus the whole system the equipment together
 to play the awesome effect.
Combined equipment


    Sand filter tank, protein skimmer, oxygen pump or fan


Matters needing attention


    Box type biological filter (biological filter box) is not recommended with 
the ozone generator while in use for the treatment of circulating water,
 residual ozone water can cause bacteria are killed, so that the biological
 filtration failure. But can lead ultraviolet sterilization device.
Where 
possible, the water remained slow and ensure high dissolved oxygen is very
 important!
In the biological filter front-end with physical filtration equipment
 such as protein skimmer, microfiltration machine, can effectively reduce the 
cleaning frequency of box type biological filter.


Material composition
    
Non toxic food grade PP or PVC, no precipitation, corrosion resistance to
 sea water. Long term use without replacement.
Contains material are of high 
specific surface area of the biological filter, such as brush, biochemical 
blanket, coral sand, porous ceramic ring, bio ball etc..
