QUANSEN is a professional enterprise engaged in production, sales, r&d and application of PAM for 20 years.
Recently, some customers to call our customer service said that our factory production of PAM effect is very good, say to want to continue our cooperation, but there is a customer and other customer is different, he said our PAM effect is not so good, but after our guidance, he smile again, actually although PAM effect is very good, but we still want to know some factors influencing the flocculating agent used, use right way is likely to allow customers to spend money in vain.
So, what are the factors that affect the use of flocculant?
I've summed up a few points.
A, pH value
In sewage treatment, the pH value of water has a great effect on the use of inorganic flocculant.
Therefore, when using inorganic flocculant, you must first measure the pH value of sewage, and then choose different kinds of flocculant according to the corresponding pH value, which is a very critical step, many customers think that inorganic flocculant is suitable for all situations, which is a very wrong approach.
Impurities in sewage
Uneven size of impurities in the water is very beneficial for coagulation, if the particles in the water are small and uniform, it will directly lead to poor coagulation effect.
If the concentration of impurity particles is too low, it is not good for coagulation.
When the impurity particles in the water contain a lot of organic matter, the coagulation effect is not very good.
There is a saying: any chemical, talking about the effect without talking about the dose is nonsense.
This is an important point that many people overlook.
When using coagulant, must pay attention to the dosage problem.
Using coagulation method to treat any wastewater, there are super good flocculant and super good dosage, generally speaking, these need to be determined through experiments in the early stage, too much dosage may cause the stability of the colloid, but too little dosage and not much effect.
Therefore, early experiments are essential.
Iv. Water conservancy conditions
In the mixing stage, flocculant and water should be mixed quickly and evenly. In the reaction stage, sufficient collision opportunities and good adsorption conditions should be created so that the flocs can obtain sufficient growth opportunities, and the small flocs that have been formed should be prevented from being broken. Therefore, the mixing intensity should be gradually reduced and the reaction time should be long enough.
These factors may affect the effect of flocculant, I believe you have a deep understanding of flocculant.
