Product Description
Polyaluminum ferric chloride (PAFC) is an inorganic polymer coagulant formed by coagulation and hydrolysis of aluminum salt and iron salt. According to the principle of Synergy, a new type of high-efficiency ferric chloride is prepared by adding iron ions or coagulant and other iron-containing compounds.
It integrates the respective advantages of aluminum salt and iron salt, obviously improves the morphology of aluminum ion and iron ion, and greatly improves the polymerization degree. Taking aluminum and iron coagulant are respectively beneficial to air flotation operation, improving the coagulation performance of polyaluminum chloride; The purification effect on high turbidity water and low temperature and low turbidity water is particularly obvious, no alkaline additives or other coagulants can be added.
Performance AdvantagesThe main performance is :
1.fast hydrolysis and weak hydration. The Alum flower formed is dense and the settling speed is fast. It is little affected by the change of water temperature and can meet the requirement of shear force in the flow process.
2.solid product is brown, reddish brown powder, easily soluble in water.
3.can effectively remove aluminum ions in water and residual free aluminum ions in water after aluminum salt coagulation.
4. Wide application range, drinking water, industrial water, domestic water, domestic sewage and industrial sewage treatment, etc.
5. less dosage, good treatment effect, save more than other coagulant10-20%Fees.
6. The usage, packaging usage and precautions are basically the same as polyaluminum chloride.

Application
Usage:
Due to the different nature of water, on-site debugging or beaker test should be conducted according to different situations to obtain the best use conditions and dosage to achieve the best treatment effect.
1. Before use, press this product to a certain concentration (10-30%) put into the alum dissolving pool, inject tap water and stir to make it fully hydrolyzed, leave it to a reddish brown liquid, and then dilute it with water to the required concentration and add coagulation. Water plant can also be equipped2-5%Direct dosing, direct allocation of industrial wastewater treatment5-10%Add.
2. The determination of the dosage can be determined according to the nature of water through production debugging or beaker experiment depending on the appropriate amount of alum flower formation, and other dosage that can be used in the water factory as a reference, under the same conditions, the dosage of this product is roughly the same as that of solid polyaluminum chloride, which is the dosage of solid aluminum sulfate.1/3-1/4. If the original product is used, it can be calculated according to the concentration of the corresponding agent. Roughly by weight ratio1:3It depends.
3. When using, pump the above prepared medicine into measuring tank, and mix the medicine with the water by metering.
4. Generally, it is used on the day of preparation. Tap water is required for dispensing. It is normal to have a slight sediment.
5.according to the original production Press: solid: water=1/5Left and right, mix and dissolve first, then add water to dilute to the content2~3%The solution is OK.
6.production Press: solid: water=1/5Le.
