Hybrid membrane is a combination of polymer materials that composed at least two different polymers of organic and inorganic materials.
Methodology 2.1 Materials 2.1.1 Materials for characterization of wastewater In the preparation to determine the characteristics of wastewater, two sources of wastewater solution from Company A were used.
Distilled water and deionized water was obtained from the environmental laboratory, Faculty of Civil Engineering, UiTM Shah Alam. 2.1.2 Preparation of thin film composite membrane The materials required for the preparation of composite membrane were obtained from Sigma Aldrich, Malaysia.
All of these materials were employed without further purification. 2.2 Methods 2.2.1 Characterization of Industrial Wastewater The wastewater was characterized by using the tests below: 2.2.1.1 Biochemical Oxygen Demand (BOD) The BOD test was conducted according to standard method ASTM D888 [11].

At present, the new cheap adsorption materials bentonite in heavy metal ions adsorption got application (LIU Taoxiang,2012), but bentonite as a new type of absorbent of the raw material, directly used for water treatment of absorbent, poor effect.
Materials and Method Materials Experiment with bentonite is clastic rocks and volcanic lava classics decency and become, including quartz, feldspar, perlite, zeolite and impurities, bentonite of montmorillonite in the content of about 60%.

In microscopic view of the TEM drilling, the material at beam-focused area was heated up due to direct electron bombardments and temperatures of the surrounding materials were raised up through heat conduction, with a negative temperature gradient radiated outward from the hottest focal spot.
Since the heat accumulation, a shallow melted pit centered at focal spot was created and the material underneath the melted pit was softened.
In theory, a straight through-pore would be more likely if we could reduce the size of the melted pit and the region of the material being softened.

Accordingly, the dispensed liquids have been expanded from the conventional pigmented ink (or standard dye-based ink) to polymers , gels, cell ink or other materials which often have higher viscosities or even contain large particles or cells[7].
The selected material is brass, which has good conductivity.

Introduction Heat treatable strengthened 7xxx series Al alloys are still a key pillar of alloy materials for the aerospace industry, which have an excellent specific strength, plastic toughness and good corrosion resistance [1-4].
Meanwhile, Fracture toughness, as an important performance index in the mechanics of materials, needs to be improved to the maximum extent possible while meeting the high strength of commercial aluminum alloys.
Materials and Methods The chemical compositions (wt.%) of three kinds of high-strength Al-Zn-Mg-Cu alloys were listed in Table 1.
