1. Surfactants have also been
widely used in textile, fiber, food, paints, polymers, plant protection,
cosmetics, pharmaceuticals as well as mining, pulp and paper industries.
2. This study was focused on
treated this wastewater sample based on decreasing the parameters so it can
comply with the regulation of environment quality act.
3. Untreated waste may damage
our environment and also present serious hazard to human and other living
thing.
4. The objective of this
project is to evaluate the effectiveness of Nanofiltration membrane in treating
the LAS contaminated wastewater from FPG Oleochemical.
5. Besides that, the membrane
performance is also studied by analyzing it surfactant retention
and the permeate flux.
6.
Therefore, optimum operating
condition of the membrane may be obtained by varying the TMP.
7. They are mainly used in
aqueous solutions and are classified according its hydrophilic group in
anionic, cationic, nonionic, and amphoteric surfactants.
8. Surfactants are strongly
adsorbed at an interface or they form colloid aggregates in solution at very
low concentrations, lowering the interfacial tension.
9. Surfactants have found many
industrial applications, such as detergency, wetting, cleaning,
emulsification, foam control and lubricity in industrial systems.
10.
Therefore, the treatment of
effluent streams containing surfactants is an important issue, either for environmental or economic
reasons.
11.
It can be adsorbed onto
suspended solids ranging from 30 to 70 % and, hence, escaping aerobic
treatment.
12.
It has also been identified
in surface water supplies in the concentrations lower than 1 μg dm-3 (Berna etal.,
1989), and in the drinking water with the concentrations of 0.001 - 0.008 mg dm-3
13.
Membrane systems have been
used in specialized applications for more than 30 years, largely for water
treatment, including desalination of seawater and brackish water.

15.
Membrane technologies are receiving
special recognition as alternatives to conventional water treatment. In the

membranes, salt is removed from every other compartment and collected in
intervening compartments.
