  In this paper we have studied Van-Der-Waals fluid system with the generalized
EOS as as discussed in the recent works of Kremer, G.M [1, 4], Vardiashvili, G
[2], Jantsch, R.C [3], Capozziello, S [5]. and are functions of energy density
and time that are different for the three types of Van der Waals fluid which
are one parameter model, two parameters model and three parameters model. We
have studied the changes in the parameters for different cosmic phases. We have
also investigated the thermodynamics and the stability conditions for these
three models. Finally, we have resolved the finite time future singularity
problems
