Hello everyone

I really have a question that I am trying to solve. it is a bit undirect and trying to get your help to answer it.. so please try:

Let us assume that we do have a water flows in a line to a filtration system (column) with a certain flow rate ( say for example 200L/H ) and we have to add some chemical before the water enters the column.. we use dosing pump to dose this chemicals.. i have to dose a certain amount of chemicals ( for example 15mg/L )..

This chemical has a streangth of 127g/L

My question is: 1- How much flow rate of chemical that must be dosing in line to the water ?

In other words: How can we convert that amount of chemicals ( 15mg/L ) to flow rate units (ml/L) ?

2- If we change the water flow rate to 400L/H, will the chemicals flow rate change as well or not ? Please explain how

It is really a tricky questions and really want your help.



Best regard

I've changed your topic title.  For future reference, please try and make the titles something that describes what the post is, not "I have a problem, please help me".  Welcome to the forums! --Macman104

Hi Bashir2008,

1. Use the specific gravity of the chemical (in either Kg/L units, or g/ml).

2. Usually, changing the flow rate will also change the dosage of the chemical (depending on the injection type - example: 1) venturi versus 2) pump.

I hope this helps,

Eugene
