1 Introduction
Water is the establishment of life. Due to the fast development of total population
across the globe, water contamination and water lack issue turns out to be a genuine
issue [1]. The release of a lot of wastewater has carried along with it incredible
difficulties to the natural environment and human wellbeing [2]. The contaminants
present in wastewater may originate from various sources like oil contamination,
herbicides, pesticides, pathogens, plastic and heavy metals [3]. Wastewater released
from textile industries if not effectively treated would establish a genuine ecological
issue for water contamination [4]. Wastewater treatment is broadly grouped under
three main categories, namely the physical, chemical and biological method. Of
these methods, the membrane process plays a vital role and it finds its application
in the purification of residential and industrial wastewater [5]. The interest for water
is expanding, and consequently, careful examination of different methodologies for
production of high grade water is essential [6].
Membrane technology has gone through a fast improvement in accordance with
most applications and specifically in accordance with purification of water [7].
Membrane technology has been broadly applied in water and wastewater treatment
for the total partition of particulate issue and microbial microorganisms, having a
size bigger than the pore size membrane [8]. Membrane technology finds its application in various fields like petrochemical industry, wastewater treatment and also in
sea water desalination [9]. Membranes will dispense high grade quality of water at a
reasonable cost and with minimum amount of energy consumption. Membranes with
various physical and porosity attributes can viably eliminate a degree of toxins [10].
On the contrary, membranes are widely classified into two broad categories based on
the type of material that is utilized in the membrane. The membrane materials can
be classified as organic or inorganic membrane material [11]. In terms of characteristic, membranes can be categorized as isotropic and anisotropic membranes [12].
Polymeric membranes have a definite pore structures and they are most commonly
employed. Apart from membranes, the different water purification technologies
which are available for eliminating the impurities from wastewater will include
electrosorption, precipitation, chemical disinfection, ion exchange and distillation
[13]. Sleek wastewaters are one of the significant toxins of the sea-going condition. This is because of the emanation of oily waters released from a variety of
origin which includes petrochemical plants and refineries [14]. Membrane filtration
is generally preferred for the treatment of sleek wastewater because of its preferences: no synthetic added substances are expected to break the emulsion, high COD
evacuation efficiencies are accomplished, and treatment methodologies are much
minimized and completely mechanized [15]. The film-based methods like pervaporation, microfiltration, nanofiltration, ultrafiltration are often utilized to eliminate oil
water emulsion [16].
