Summarize the main technical methods to improve the flocculation and precipitation of polyaluminum chloride The effect of flocculation and precipitation of polyaluminum chloride can be said to be directly related to the effect of sewage treatment. Recently, many customers have consulted how to improve the flocculation and precipitation of polyaluminum chloride Effect, on this issue, the technical department combined with many years of experience in the major sewage treatment plants, are summarized as follows: want to enhance the effect of PAC flocculation precipitation, we must first combine sewage water quality, to select the PAC Model, only to find the model in order to achieve a multiplier effect in order to be able to say how to improve the PAC flocculation effect, if you can not find the model, no matter what method can not play a good treatment effect, let alone how to improve the polymerization of chlorine Aluminum flocculation and sedimentation effect. Polyaluminum chloride mainly through the reaction with the material salts in water to generate large sedimentable substances to achieve the effect of water purification, but different manufacturers need to purify the sewage composition is not the same, which contains the floating gel size, Uniformity, and the nature is not the same, all of which determine the PAC dosage and flocculation speed differences, for each plant, the same specifications of the optimal flocculation speed is not the same, the speed is generally not artificial Intervention, if you intervene, may result in decreased flocculation or inadequate response, resulting in residual polyaluminium chloride, resulting in waste of raw materials. Therefore, we generally recommend the use of polyaluminum chloride, the time to find specialized technical personnel to carry out water samples, and then develop the program, formulated after the human intervention is not, if you have not developed a specific program, are based on experience to add , We suggest that you do the water sample analysis, if you do not have this technology, then you can contact us. If you want to operate your own, we suggest the following: First, do a coagulation experiment of PAC, through the small test launch the correct dosage, it is also clear whether the water is alkaline or acidic, if the water is acidic or partial Alkali, it is necessary to adjust the PH value, as long as these preliminary work done, it is to improve the effect of flocculation and precipitation of polychlorinated aluminum prepared in order to fully meet the water quality standards.
