Mariemm,

Consider to ask support from Vendors , they know their products and what will be  the best process conditions after performing Tests ( Jar test). They will tell you how is  the material ( solid, liquid form) , what is the equipment needed based on consumption and concentration (size) , the type of mixing , the pump ,etc 

 

Regards

Breizh

in fact i need to design the coagulant and flocculant tanks  ( length , heigth , diametr and capacity ) as well as the dose and flow rates of chemical injection .I've found some equations but it wasn't helpfull 

 some of equations are : 

D =Q*X/d where D the total injection flow , X is the optimum dose ( 35 ppm of a coagulant and a 5 ppm of the flocculant) that's all 

i need some documentation ( sheet or a standard ...)

Mariemm ,

Your equation is weird !

Just do a mass balance , of course you need input like property of the solution ( g active mater/liter) , quantity to be injected (kg/h) , the quantity you want to keep (minimum stock) , How often do you want to do replenishment ?  this will give you an estimate of the size ,

some L/D standard for your tank then play around to get the best design to install agitator , Sensor , overflow ,....

 

Hope this helps
