Containment Solutions Offered by Nilex

Structures built to contain things need to be adequately lined so that they continue to hold their contents without harming the surrounding ecosystem. Some examples of containment structures include landfills, ponds, tanks, etc. Nilex offers both primary and secondary containment solutions.

Primary containment solutions by Nilex

The intent of primary containment solutions is to prevent the seepage of the contents of a containment structure or unit into the ground below. This is attained by lining these containment units with geomembranes. Low density polyethylene membranes are used as they are flexible and can be easily stretched across the inner lining of the containment units. Geomembranes reinforced with XR-5 are specifically used for containment units that store chemicals as these membranes are resistant to chemicals.

Secondary containment solutions by Nilex

Secondary containment solutions are preferred for containment units that store industrial liquids. Industrial leaks are hazardous to human life and the environment and it is therefore extremely important that spills are contained. In addition to being resistant to chemicals, the geomembranes used to line the secondary containment units are also resistant to high temperatures. Nilex provides containment rings that check the spread of spills, if they occur.

Significance of Primary Containment Installation Services

Primary containment applications are used for preventing the leaching of materials into the surrounding soil and groundwater.These containment solutions are designed to protect people and the immediate laboratory environment from exposure to infectious agents.

These containers are usually designed along with secondary containment systems to contain or control a release from the primary containment. A tank, vessel, pipe, transport vessel or equipment is often used as the primary container or used for the transferring material. For instance, primary containment tank lining systems are installed inside steel, concrete and wood containment structures to ensure containment and protection of the tank and the environment. Reducing Loss of Primary Containment (LOPC’s) or commonly referred to as “leaks” in a refinery is essential to improve reliability and avoid losses. It is the reason why secondary containment is implemented to assure maximum protection of the material, people and the assets of an organisation.

Containment solution providers offer primary and secondary containment Installation Services for the containment of a variety of liquids, solids and waste materials. They also provide specialty materialsfor unique chemical and/or thermal conditions. They also provide liner Installation Services, design assistance, fabrication and construction services for containment applications.

The Differences Between Nonwoven Geotextiles and Woven Geotextiles

Geotextiles are a permeable synthetic textile material, made from either polypropylene or polyester. Geotextiles are used for several different applications in a range of civil and environmental engineering structures that are mainly associated with soil, there are 5 key functions that geotextiles perform:

1.) Separation

2.) Reinforcement

3.) Filtration

4.) Protection

5.) Drainage

What is a Nonwoven Geotextile?

Nonwoven Geotextiles are produced by entangling fibres, long or short together, either through needle

punching or other methods.  Some additional thermal treatment is then applied to further improve the strength of the geotextile. Due to this manufacturing process and their permeable properties, non-woven geotextiles are generally best used in applications of drainage, separation, filtration and protection. Nonwoven fabrics are typically classified by their weight per square yard, for example a square yard of 6 oz. geotextile, weighs 6 ounces. They feel and look like felt.

What is a Woven Geotextile?

Woven Geotextiles are manufactured by blending and weaving fibres together on a loom, forming one

uniform length. The result is a product that is not only strong, which makes them a great fit for applications like road construction and parking lots, but also remarkably well equipped to handle ground stabilisation problems.  They are relatively impermeable (water does not flow through very well) and do not offer the best separation against fines.
