How to determine the concentration of polyaluminum chloride in sewage treatment? Polyaluminium chloride used in sewage treatment, which is mainly for the yellow or yellowish brown solid powder, water treatment has the role of flocculation, suitable for printing and dyeing plants, paper mills, tanneries and other industries water treatment plants, but also has Removal of phosphorus, with phosphate in the wastewater generated precipitation, suitable for domestic sewage plant phosphorus removal. Pollution treatment using polyaluminium chloride are generally used as a flocculant, used for individual phosphorus removal agent. Because of the different functions, the concentration of the product allocation and dosage are very different, under normal circumstances how should we determine the concentration and amount of PAC? Stirring should be used in what way? Solid aluminum chloride content of 28% of the national standard, the liquid content of 10%. The solid should be dissolved before using the solid concentration of 10% (dissolved gas mixing or mechanical stirring can be used), the dosage can be based on untreated turbidity of raw water to determine the best dosage, the general water turbidity in the 100-500mg / l, every 10 tons of water dosage 10-20kg, according to the specific test to determine. Polyaluminium chloride used in sewage treatment, which is mainly for the yellow or yellowish brown solid powder, water treatment has the role of flocculation, suitable for printing and dyeing plants, paper mills, tanneries and other industries water treatment plants, but also has Removal of phosphorus, with phosphate in the wastewater generated precipitation, suitable for domestic sewage plant phosphorus removal. The use of polyaluminium chloride for municipal wastewater or industrial wastewater, the corresponding dosage and dosage are different, in order to be accurate and improve the efficiency of treatment, it is best to try to ensure that the amount of small and on-site testing and effect.
500 ~ 1000kg According to the actual situation to adjust, there is a need to allow engineers to the scene to experiment with you, the data more accurate
That is because of the use of poor quality polyaluminum chloride, that things are not good itself is yellow
