Calculation of the addition concentration of flocculants and dispersants
Thread Content
I would like to ask everyone: where are the concentrations of flocculants and dispersants calculated? That is, where are these concentrations determined? How to calculate it?
I checked our forum before posting this question; I know that the dispersant should be added at a concentration of 60–100 ppm, while the coagulant should be added at 1–3 ppm. What I really want to know is how to calculate the actual amounts of dispersant and coagulant to be used, given the known concentration of the mixture and the amount to be added
60-100 ppm for dispersant, and 1-3 ppm for coagulant – these values refer to the ratio of the chemical to the total amount of ash water. Therefore, it is first necessary to know the amount of ash water, after which the amount of chemical to be added can be calculated. Finally, the desired concentration of the chemical (solid content) must be taken into account to determine the ultimate amount to be added. During actual operation, appropriate adjustments also need to be made based on the water quality test indicators.
Does the total amount of graywater refer to the water output from the graywater tank?
60-100 ppm of ash water dispersant is generally calculated based on the volume of low-pressure ash water circulation, while 1-3 ppm of flocculant is calculated based on the volume of water flowing into the sedimentation tank
