Integral problem for 1 - (1/t).dt?

Question

I work out an equation to calculate the decrease of water concentration of water which is filtered. I come to "dC/C0 = 1 - (1/t).dt"

Now I should integrate so 1/C0.INT (dC) = ... ?? what is the integral of the last part 1 - (1/t).dt ?? What to do with the "1".. since this is niot a function of x... will this simply be INT (-(1/t).dt) ??

thanks!
