處理飲用水的話，含量低的聚合氯化鋁會(huì)有較多雜質(zhì)和水不溶物，所以要求用高含量。特別是造紙，化妝品制作中更是要用高含量的。

處理飲用水必須用飲水級(jí)的，工業(yè)級(jí)的在檢測(cè)時(shí)不檢測(cè)重金屬，另外水不溶物也高于飲用水的，總的來(lái)說(shuō)飲用水級(jí)的關(guān)乎人命，不能亂用，一定要是真正的飲用水級(jí)的，如果工業(yè)級(jí)的被用于飲用水，隱患很多。而且純度不同，工業(yè)用都是26-28%，飲用水用30%。

而污水處理的話，含量高低要求并不嚴(yán)格，含量低的不是太多就行，可以多投放些藥劑也可以達(dá)到預(yù)定的效果。

河南安家凈環(huán)?？萍加邢薰緦?zhuān)業(yè)生產(chǎn)聚氯化鋁，主要分為飲水級(jí)，工業(yè)級(jí)，生產(chǎn)工藝主要分為噴霧法，滾筒法，資源貧乏山區(qū)的水處理時(shí)，直接加入水箱或水池中，攪拌均勻后靜止放置，上清液使用。一般情況下，50kg的水使用1g噴霧干燥型聚合氯化鋁。首先將噴霧干燥型聚合氯化鋁溶于10%～30%的水溶液中，然后加入待處理水中。根據(jù)處理后水的濁度，可適當(dāng)提高或降低耗水量。

與普通聚合氯化鋁相比，噴霧干燥型聚合氯化鋁具有較好的吸附性能、較大的絮凝塊、沉降效果和處理后的水質(zhì)較好。一般噴霧干燥型聚合氯化鋁采用更加先進(jìn)的生產(chǎn)工藝，噴霧干燥法生產(chǎn)的聚合氯化鋁也分為了飲水級(jí)聚合氯化鋁和工業(yè)級(jí)聚合氯化鋁以及食品級(jí)聚合氯化鋁。飲水級(jí)聚合氯化鋁主要用于人們的日常飲用水，工業(yè)級(jí)聚合氯化鋁主要用于工業(yè)廢水的處理，而食品級(jí)聚合氯化鋁多用于食品添加劑和醫(yī)用方面。

噴霧干燥型聚合氯化鋁的產(chǎn)品質(zhì)量很多時(shí)候關(guān)系到人們的生命健康，因此，生產(chǎn)噴霧干燥型聚合氯化鋁具有明確而嚴(yán)格的國(guó)家標(biāo)準(zhǔn)，可以保證人們的健康和安全。

滾筒式聚氯化鋁 鋁含量一般,水不溶物高,多用于污水處理.

板框式聚氯化鋁 鋁含量高， 水不溶物低. 用于污水處理和飲用處理.

噴霧干燥聚氯化鋁 鋁含量高， 水不溶物低，溶解速度快，用于飲用水及更高標(biāo)準(zhǔn)水處理.

PAC聚氯化鋁由于噴霧干燥穩(wěn)定性好，適應(yīng)水域?qū)?，水解速度快，吸附能力?qiáng)，形成礬花大，質(zhì)密沉淀快，出水濁度低，脫水性能好等優(yōu)點(diǎn)，在同樣水質(zhì)的情況下，噴霧干燥聚氯化鋁投加量減少，尤其在水質(zhì)不好的情況下，噴霧干燥產(chǎn)品投量與滾筒干燥聚氯化鋁相比，可減少一半，不僅減輕了工人的勞動(dòng)強(qiáng)度，而更重要的是減少用戶(hù)的制水成本。除此之外，用噴霧干燥產(chǎn)品可保證安全性，減少水事故，對(duì)居民飲用水非常安全可靠。When treating drinking water, polyaluminium chloride with low content will have more impurities and water insolubles, so high content is required. Especially in papermaking, cosmetics productio型。但是實(shí)驗(yàn)時(shí)要選擇具有參考價(jià)值的污泥或廢水。廢水或者污泥的種類(lèi)都有很多，那么安家凈就對(duì)廢水取樣進(jìn)行一下說(shuō)明，希望能給廣大買(mǎi)家提供便利。

現(xiàn)階段技術(shù)性最為老The flocculation process of polyaluminium chloride is simple. In the sewage treatment profession, flocculation is one of the oldest solid-liquid separation methods. Because of its wide applicability, simple processing technology and low treatment price, flocculation method is still widely used in drinking water, domestic sewage and industrial sewage treatment at this stage. Polyaluminium chloride (PAC) is an excellent inorganic macromolecule flocculant. It was first developed in Japan and put into industrial production in the 1960s. It is the most sophisticated flocculant with the highest sales volume at the present stage. PAC has the advantages of fast floc formation, good sedimentation performance, low alkalinity consumption in water, especially strong adaptability to changes in water temperature, pH value, turbidity and organic matter content. The whole process of flocculation of polyaluminium chloride is actually a destabilization process. The so-called destabilization is the process of destabilizing colloidal particles. The solid particles originally uniformly dispe

Drinking water must be treated at drinking water level. Heavy metals are not detected at industrial level, and insoluble substances in water are also higher than drinking water. Generally speaking, drinking water level is related to human life and can not be used arbitrarily. It must be a real drinking water level. If industrial level is used for drinking water, there are many hidden dangers. And the purity is different, industrial use is 26-28%, drinking water is 30%.

And sewage treatment, the content requirements are not strict, low content is not too much, you can put more medicines can also achieve the desired effect.

Henan an Jia Jing Environmental Protection Technology Co., Ltd. specializes in the production of polyaluminium chloride, which is mainly divided into drinking water level and industrial grade. The production process is mainly divided into spray method and roller method.

Drum-type polyaluminium chloride is generally used for sewage treatment because of its high water insoluble content.

Plate-frame polyaluminium chloride has high content and low water insoluble. It is used for sewage treatment and drinking treatment.

Spray drying has high content of polyaluminum chloride, low insoluble substance and fast dissolution rate. It is used for drinking water and higher standard water treatment.

PAC polyaluminium chloride has the advantages of good stability in spray drying, wide adaptation to water area, fast hydrolysis speed and strong adsorption capacity. It has the advantages of large alum, high quality and fast sedimentation, low turbidity and good dewatering performance. Under the same water quality, the dosage of spray drying polyaluminum chloride is reduced, especially when the water quality is not good, the product volume of spray drying is compared with that of drum drying polyaluminum chloride. It can be reduced by half, which not only reduces the labor intensity of workers, but also, more importantly, reduces the cost of water production for users. In addition, spray drying products can ensure safety and reduce water accidents, which is very safe and reliable for drinking water.
