present in water. Generally, membranes are manufactured compounds contains
several billions of micro pores connected through particular boundaries, which
don’t stop the water to go through (Shih 2005). A main impetus, for example,
weight contrast between the penetrate and feed sides, is expected to pass through
the water by the layer (Van der Bruggen et al. 2003). For the most part, two types of
weight driven membrane filtrations are available: (1) low-weight film forms, for
example, ultrafiltration (UF) and microfiltration (MF); and (2) pressure membrane
forms, for example, nanofiltration (NF) and Reverse Osmosis (RO) (Mondal et al.
