PAFC PAFC [product name], also known as ferric complexes, the English abbreviation for PAFC PAFC DESCRIPTION (PAFC) is mainly aluminum, iron supplement (including iron is about 2-3%) of the new composite amorphous, inorganic polymer purifying agent. Ferric iron, after hydrolysis to form polynuclear complexes. At low temperatures, with the formation of alum in water than the major, forged alum tightly characteristics. This is mainly iron and hydrolysis rate of hydrolysis is affected by temperature very reason. Since aluminum salts in addition to color performance, effluent chroma greatly reduced. Therefore have a PAC and iron salts features and characteristics, to overcome the PAC at the time of low temperature and low turbidity water difficulties. Therefore, the water is better than normal water purification products. 【Properties】 PAFC appearance of brown-red powder or grain shape. Use products in drinking water, sewage, industrial water, industrial waste water, industrial water recycling, urban water supply and urban wastewater purification. Advantages】 【hydrolysis speed, hydration weak. Formation of alum dense settlement rate. Affected by small changes in water temperature to meet the liquidity generated through the process of PAFC shear force requirements. Can effectively remove the source of aluminum ions and aluminum salts in water after coagulation residual water free state aluminum ions.

If the original using a liquid product, according to the discretion of the appropriate drug concentration calculations. Generally at a weight ratio of 1:3 may be. 3, when used, to the preparation of a good liquid, pumped into the measuring tank, through the metering and dosing of raw water coagulation liquid. 4, under normal circumstances the date using the date of preparation, dispensing needs water, a little sediment is normal. 5, the production of press: Solid: water = 1/5, the first mixed dissolved, then diluted with water to a content of 2 to 3% solution can be. [Note] ⒈ external plastic sacks, plastic film package, net weight 25kg, can be modified according to user requirements. ⒉ the goods prohibited mixed with toxic substances, transport and storage, the product should be stored in dry, ventilated, cool place, and do not get wet. ⒊ Handle with care when loading and unloading, the solid product storage period of one year.
