The advantages of organic flocculants such as PAM are economical and simple to use, but the disadvantages are large dosage, low flocculation effect, and the disadvantages of high cost and high corrosivity. So how to use it to achieve economic and effective? This problem has been plagued by customers. We have thoroughly studied this issue from the customer's point of view.
The flocculant is undoubtedly the most critical factor in the whole process of sewage treatment, and it is also a product that consumes relatively more cost in the wastewater treatment process. For different wastewater quality, including different industries, whether it is organic sewage or inorganic, it has a matching PAM dosage model.
Before purchasing a flocculant such as PAM, we should contact our manufacturer and conduct sampling analysis through our professional laboratory. We can use the PAC+PAM scheme because the suspended solids are generally negative.
Then, a test for determining the amount of polyaluminum chloride PAC can be made through the test chamber to determine the amount of PAC used alone and the turbidity-removing effect curve.
Then, the laboratory beaker experiment is used to determine the ratio of PAC to CPAM. If the amount of PAC used in the polymerization of aluminum chloride is 1/3 of the A value, it is estimated that how much PAM is needed to bridge the aggregation effect of PAC. . In addition, we pay special attention to the PAM ion model we are facing. There are different anions and cations. Of course, if the wastewater is weakly acidic, it is also possible to use non-ionic PAM and polyaluminum chloride for matching.
Through this experiment, the customer can determine the optimal use ratio of PAC and PAM. After the experiment is completed and the ionicity of the PAM is selected, the sewage treatment enterprise can obtain the best effect and the lowest flocculant agent cost.
