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!

眾所周知，含有懸浮物顆粒的水與絮凝劑充分混合，使水中形成膠體顆粒的雙電層被壓縮。當(dāng)膠體顆粒流過多介質(zhì)過濾器的濾料層時(shí)，濾料縫隙對懸浮物起篩濾作用使懸浮物易于吸附在濾料表面。當(dāng)在濾料表層截留了一定量的污物形成濾膜，隨時(shí)間推移過濾器的前后壓差將會(huì)升高，直至失效。

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.

此時(shí)需要利用逆向水流反洗濾料，使過濾器內(nèi)石英砂及無煙煤層懸浮松動(dòng)，從而使粘附于石英砂及無煙煤表面的截留物剝離并被水流帶走，恢復(fù)過濾功能。本工程中使用的雙層濾料是在過濾層上部放置較輕的大顆粒無煙煤，下部為大比重的小顆粒石英砂，這樣可以充分發(fā)揮整個(gè)濾層的效率、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.

無煙煤濾料采用優(yōu)質(zhì)原煤為原料，經(jīng)精選、破碎、和兩次篩分而成，外觀光澤好，呈球狀，機(jī)械強(qiáng)度高，抗壓性能好，化學(xué)性能穩(wěn)定，不含有毒物質(zhì)，耐磨損，在酸性、中性、堿性水中均不溶解，另外無煙煤顆粒表面粗糙，有良好的吸附能力，孔隙率大(≥52%)，有較高的含污能力，因質(zhì)輕，所需反沖洗強(qiáng)度較低，可節(jié)省大量反沖洗水量及電能。

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.

無煙煤濾料是特別從深井礦物中精選的，具有高的含碳量百分比。 水濾料采用人工分類，可減少無關(guān)礦物質(zhì)并降低灰分含量。 水濾料還經(jīng)過過濾和沖洗，確保其適合水過濾之用。 由于具有較好的固體顆粒保持能力，因此無煙煤能夠可靠地提高懸浮顆粒清除能力。 此外，它的均勻系數(shù)較低，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.
