Product Description
Polyaluminum ferric chloride
[Product introduction]
The appearance of polyaluminium ferric chloride is brownish red powder or grain shape.
Polyaluminium ferric chloride, or PAFC for short, is an inorganic polymer coagulant formed by the coagulation and hydrolysis of aluminum salt and iron salt.Hydrolysis is fast and hydration is weak.Alum flowers formed dense, sedimentation rate fast.It is less affected by the change of water temperature and can meet the requirement of shearing force during flow.It can effectively remove the aluminum ions in the raw water and the residual free aluminum ions in the water after aluminum salt coagulation.
[Application field]
Purification of domestic drinking water, domestic sewage, industrial water supply, industrial sewage, industrial circulating water, urban water supply and urban sewage.Mainly used for printing and dyeing wastewater, steel mills, sewage treatment plants, paper mills and other industrial sewage treatment.
[Product advantages]
PAFC combines the advantages of aluminum salt and iron salt coagulant, and introduces sulfuric acid anion, which significantly improves the polymerization morphology of aluminum ion and iron ion and greatly improves the degree of polymerization.Especially when dealing with high turbidity water and low turbidity water at low temperature, it is characterized by low residual turbidity, low color, rapid flocculation of flocculation, high adsorption and good dewatering of sludge filter.
The product is low in dosage and has good treatment effect, saving 10-20% cost compared with other coagulants.
[Method of use]
1. Due to the different nature of raw water, on-site adjustment or beaker test should be conducted according to different conditions to obtain the best use conditions and dosage to achieve the best treatment effect.
2. Generally, the dosage of pharmaceutical products is 1-15g/ton of solid products. The specific dosage will be determined by the user according to the amount of actual experiments due to the different water quality.If the original liquid product is used, it can be calculated and determined according to the concentration of the corresponding agent.It depends on the weight ratio of 1:3.
3. After the product is dissolved in water, the dilution ratio is generally 2% to 20% (weight percentage).Generally, it is used on the day of preparation. The dispensing requires tap water.Slight precipitation is normal.
[Matters needing attention]
1. The product is corrosive, and the equipment needs to be treated with corrosion prevention, and the operator needs to be equipped with labor protection measures.
2. This product is prohibited to be mixed with other chemicals, transported and stored. The product should be stored in a dry, ventilated and cool place in the room and not exposed to moisture.
3. Handle with care during loading and unloading. The storage period of solid products is 12 months.
