The important step of filtering water quality is to remove some suspended solids in water. Only by choosing suitable filter material can a good effect be achieved. Now Shandong Multimedia Filter Factory will introduce to you which filter material of Multimedia Filter can effectively remove suspended solids. I hope that you like it!

众所周知，含有悬浮物颗粒的水与絮凝剂充分混合，使水中形成胶体颗粒的双电层被压缩。当胶体颗粒流过多介质过滤器的滤料层时，滤料缝隙对悬浮物起筛滤作用使悬浮物易于吸附在滤料表面。当在滤料表层截留了一定量的污物形成滤膜，随时间推移过滤器的前后压差将会升高，直失效。

It is well known that water containing suspended particles is fully mixed with flocculants, so that the electric double layer formed colloidal particles in water is compressed. When the colloidal particles flow through the filter material layer of the multi-media filter, the filter material gap plays a sieving role on the suspended matter, which makes the suspended matter easily adsorbed on the surface of the filter material. When a certain amount of dirt is intercepted on the surface of the filter material to form a filter membrane, the pressure difference between the front and back of the filter will increase over time until it fails.

此时需要利用逆向水流反洗滤料，使过滤器内石英砂及无烟煤层悬浮松动，从而使粘附于石英砂及无烟煤表面的截留物剥离并被水流带走，恢复过滤功能。本工程中使用的双层滤料是在过滤层上部放置较轻的大颗粒无烟煤，下部为大比重的小颗粒石英砂，这样可以充分发挥整个滤层的效率、提高截污能力。

At this time, it is necessary to use reverse flow backwashing filter material to make the suspension of quartz sand and anthracite loose in the filter, so that the interceptor adhering to the surface of quartz sand and anthracite can be peeled off and taken away by water flow to restore the filtering function. The double-layer filter material used in this project is to place lighter large granular anthracite on the top of the filter layer and large proportion of small granular quartz sand on the bottom. This can give full play to the efficiency of the whole filter layer and improve the ability of pollution interception.

无烟煤滤料采用原煤为原料，经精选、破碎、和两次筛分而成，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，另外无烟煤颗粒表面粗糙，有良好的吸附能力，孔隙率大(≥52%)，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。

Anthracite filter material is made of high-quality raw coal, which is selected, crushed and screened twice. It has a glossy appearance, high mechanical strength, good compressive performance, stable chemical performance, no toxic substances, wear resistance, insoluble in acidic, neutral and alkaline water, and rough surface of anthracite particles. Good adsorption capacity, high porosity (> 52%) and high contamination capacity. Because of light weight, backwashing intensity is low, which can save a lot of backwashing water and electricity.

无烟煤滤料是特别从深井矿物中精选的，具有高的含碳量百分比。 水滤料采用人工分类，可减少无关矿物质并降低灰分含量。 水滤料还经过过滤和冲洗，确保其适合水过滤之用。 由于具有较好的固体颗粒保持能力，因此无烟煤能够可靠地提高悬浮颗粒能力。 此外，它的均匀系数较低，有助于加快流速，

Anthracite filter material is specially selected from deep well minerals with high carbon content. Artificial classification of water filter materials can reduce irrelevant minerals and ash content. Water filters are also filtered and rinsed to ensure that they are suitable for water filtration. Anthracite can reliably improve the removal ability of suspended particles because of its good solid particle retention ability. In addition, its uniformity coefficient is low, which helps to accelerate the flow rate.
