Introduction

Geomembrane is a very low permeable synthetic membrane which is used in various geotechnical engineering projects to control water or gas leakage. It has been confirmed that for this application, geomembranes are more efficacious than other traditional products such as concrete, asphalt, and compacted clay. This product has a wide range of properties, i.e. physical, mechanical and chemical resistance, to protect our environment and water resources. It is worth mentioning that the antibacterial activity of polymers reinforced with silver nanoparticles is stable and its high antibacterial efficiency has been observed against different species of bacteria. Silver ions and its compounds can kill a wide range of bacteria, while they have no toxic effect to the human body. Therefore, the use of silver in different forms is a common method of protection against bacteria.

Introduction

Biodegradable plastic is plastic that decomposes naturally in the environment. This is achieved when microorganisms in the environment metabolize and break down the structure of biodegradable plastic. The end result is one that is less harmful to the environment than traditional plastics. Biodegradable plastics can be composed of bioplastics, which are plastics made from renewable raw materials. There are normally two forms of biodegradable plastic, injection molded and solid. The solid forms normally are used for items such as food containers, leaf collection bags, and water bottles.

Introduction

Desalination is considered as a common solution for the regions with shortage of fresh water resources. There are various methods for brackish and sea water desalination.

PNF Company has developed modified electro dialysis technology as an appropriate and efficient for desalination.

The developed process is an electrochemical technique in which the ionic contaminants are removed from the aqueous solution. In this method, separation of salt from water is conducted in the presence of anionic and cationic membranes under the influence of an electric field.
