无烟煤滤料优点多，目前普遍采用双层、三层快速过滤材料，主要用于无阀滤池、虹吸滤池、高速中速过滤器。优点介绍如下：
1、外观光泽好，呈球状，机械强度高，抗压性能好，化学性能稳定，不含有毒物质，耐磨损，在酸性、中性、碱性水中均不溶解。
2、粒径配级合理，比表面积好，它在过滤过程中所起作用的好坏，直接影响着滤后的水质。
3、另外无烟煤颗粒表面粗糙，有良好的吸附能力，孔隙率大(>50%)，有较高的含污能力，因质轻，所需反冲洗强度较低，可节省大量反冲洗水量及电能。
在多层滤料滤池的使用中既不跑煤，又不混层，以它固有的特性而著称。无烟煤滤料的原料采用优质白煤。所产滤料经国家建设部水处理滤料质量检测中心鉴定各项指标均符合部颁标准，是城镇给排水以及工业水处理理想的优质过滤材料。无烟煤滤料可用于生活饮用水和工业生产用水以及各种池型的普通快滤池、双层及三层滤池、各种污水过滤器、净水机械过滤器及化工、冶金、热电、制药、造纸、印染、食品等的生产前后的水质处理。
为保证过滤后水质处理效果，无烟煤滤料过滤罐每隔一定时间就要进行反冲洗。反冲洗技术参数主要有反冲洗周期、反冲洗时间和防冲洗强度。其中反冲洗周期的长短直接影响水质处理效果。无烟煤滤料滤罐反冲洗周期过于频繁：一是增加系统负荷，影响水质稳定运行时间；二是增加系统能耗，造成水资源不必要的浪费。为此确定合理反冲洗周期，既节能又能减轻工人的劳动强度。
在保证无烟煤滤料滤罐滤后出水水质的前提下，以减轻工人劳动强度，提高水质站精细管理水平为目的，合理制定无烟煤滤料过滤罐反冲洗周期至关重要。最主要是通过对工艺流程水质站的来水、出水水质和系统压差进行分析，进而确定经济合理的反冲洗周期。

Anthracite Filter Media
Anthracite filter material is the use of high quality anthracite as raw materials, through the selection of broken, powder, sieve and other processing technology is generally adopted in the double layer, three layers of fast filter material. Applicable to general acid, neutral alkaline purification treatment, with a good specific surface area, the indicators are up to the standard.
Anthracite filter material performance requirements:
1 high mechanical strength, crushing rate and wear rate and should not be greater than 3% (percentage by mass).
2 chemical stability, no toxic substances. In general acid, alkaline, neutral water are not dissolved. Hydrochloric acid soluble rate is 0.68% (standard 3.5) can reach a good purification effect in all kinds of water.
3 particle size distribution is reasonable and the specific surface area is large. Product appearance is spherical and angular, good gloss, three times by mechanical vibration screening, grading in accordance with the relevant technical indicators.
4 diameter range is less than the specified minimum size by weight of not more than 5%.
Anthracite filter material use:
Anthracite filter material is widely used in the country, the best filter water purification materials. Anthracite filter material using artificial classification, can reduce irrelevant minerals and lower ash content. Through selection, crushing, and two times screening, shiny appearance, spherical, high mechanical strength, good compression performance, stable chemical property, does not contain toxic substances, abrasion resistance, in acidic, neutral and alkaline water shall not be dissolved, also anthracite coal particle rough surface, have good adsorption capacity, porosity, higher carrying capacity, because of the quality of light, backwashing intensity is low, save a large number of anti washing water and electricity.
Anthracite filter material widely used, large range of adaptation. Can be used for drinking water and industrial production of water and a variety of pool type of ordinary rapid filter. Double layer and three layer filter, all kinds of sewage filter, water purification machinery and chemical, metallurgy, thermal power, pharmaceutical, food and so on before and after the production of water treatment.
Anthracite filter material characteristics: it is the most prominent feature is stable chemical performance, with good specific surface area, in general acidic, neutral and alkaline water will not be dissolved, with sufficient mechanical strength and practical in general acidic, neutral and alkaline purification treatment, is currently single, double, triple filter are indispensable material. In the filter speed, the cycle of action, water quality stability and other aspects of a clear guarantee.
Anthracite filter media has many advantages. The commonly used double layers and three layers of rapid filtration materials, mainly used for non valve filter, siphon filter, high speed medium speed filter. Advantages are as follows:
1, the appearance of good luster, is spherical, mechanical strength, high compression performance, stable chemical properties, no toxic substances, wear resistance, in acid, neutral, alkaline water are not dissolved.
2, particle size distribution is reasonable, the specific surface area is good, it plays a role in the filtration process is good or bad, a direct impact on the filter after the water quality.
3, in addition to the anthracite particles rough surface, a good adsorption capacity, high porosity (>50%), have a high capacity of pollution, due to light weight, low required back washing intensity is low, can save a lot of water and electricity.
In the use of multi-layer filter media filter is not running coal, but also mixed layer, it is known for its inherent characteristics. The raw material with high quality anthracite anthracite. The filter material by the national Ministry of construction water treatment filter material quality inspection center for identification of the indicators are in line with the standard issued by Ministry of urban water supply and drainage and industrial water treatment ideal quality of filter material. Anthracite filter media can be used for water quality of drinking water and water for industrial production and a variety of pool type of conventional rapid filter, double layer and three layer filter, all kinds of water filters, water purification filters and chemical machinery, metallurgy, thermal power, pharmaceutical, paper making, printing and dyeing, food production and processing.
In order to ensure the quality of filtered water treatment effect, anthracite filter material filter tank every time it is to be carried out anti flush. The main parameters of the anti - washing technology are anti - washing cycle, anti - washing time and anti - washing intensity. The length of the counter flushing cycle directly affects the water quality treatment effect. Anthracite filter material filter tank anti washing cycle is too frequent: first, increase the system load, affect the water quality and stable running time; two is to increase the system energy consumption, resulting in unnecessary waste of water resources. To this end to determine a reasonable anti washing cycle, both energy saving and can reduce the labor intensity of workers.
In ensuring the anthracite filter material of the filter tank effluent water quality under the premise, in order to reduce the labor intensity of workers, improve water quality station fine management level for the purpose of, develop a reasonable anthracite filter tank backwash cycle is crucial. The most important is a station on the process of water inflow, water quality and system by the differential pressure were analyzed, and then determine the economic and reasonable backwash cycle.
