Everyone may be familiar with polyaluminium chloride! So sometimes it is often thought that polyaluminum chloride is polyaluminium chloride! In fact, although they are very similar in many aspects! However, they are two different water treatment products after all! Next, let me tell you some tips about polyaluminium ferric chloride!
Let me first introduce you to Polyaluminum Ferric Chloride (PAFC)!
It is a kind of inorganic polymer coagulant which is hydrolyzed by aluminum salt and iron salt. According to the synergistic principle, a new type of high-efficiency mixing is obtained by adding elemental iron ions or combining iron oxide with other iron-containing compounds. Coagulant. It combines the advantages of aluminum and iron salts, and has a significant improvement in the morphology of aluminum ions and iron ions, and the degree of polymerization is greatly improved. Taking aluminum and iron coagulants respectively to improve the air flotation operation, improve the coagulation performance of the polyaluminum chloride; the purification treatment effect of high turbidity water and low temperature and low turbidity water is particularly obvious, without adding alkaline additives or Other coagulants.
The next step is the characteristics of polyaluminium ferric chloride! It has nine characteristics:
(1) Polyaluminium ferric chloride is mainly used for the purification of drinking water and industrial feed water, as well as the treatment of industrial wastewater. It is currently the most widely used flocculant in domestic water supply and industrial water treatment.
(2) Polyaluminum ferric chloride has good flocculation, and has the advantages of large sputum flower, low dosage, high efficiency, rapid sedimentation and wide application range.
(3) Polyaluminium ferric chloride can be used at low temperature, suitable for pH 5-9, no need to add alkali after adding, good flocculation effect and less mud production.
(4) The effective dosage of the polyaluminum chloride product is 20-50 mgL. The liquid product can be directly metered and added, and the solid product needs to be formulated into a 10%-15% solution in the dissolution tank, and then metered according to the required concentration.
(5) Polyaluminium chloride product can also be used to remove heavy metals such as iron, manganese, chromium and lead contained in water, as well as fluoride and oil in water, so it can be used to treat various industrial wastewaters.
(6) The polyaluminum chloride iron product has strong adaptability to treated water, especially for the treatment of high turbidity water; the stable coagulation effect can still be maintained when the water temperature is low.
(7) The color of water and the heavy metals such as iron and manganese are low after purification with polyaluminium ferric chloride, and the corrosion effect on equipment is small.
(8) When using polyaluminum ferric chloride, the problem of uneven mixing may occur, and it may be added after dilution.
(9) Polyaluminum ferric chloride can be combined with weak cationic polyacrylamide, combined with aluminum sulfate or ferric chloride for sludge preparation.
This is the little knowledge of polyaluminum ferric chloride that I introduced to you today! I believe everyone has already realized it deeply! If there is anything I don't understand! You can find Henan Huaquan!
