Reservoirs Iiners are a crucial element in the treatment system of many municipalities throughout the world. Many old reservoirs are built with concrete or asphalt bottoms which have leaked significant volumes of water costing millions of dollars.
These Liners are specially formulated to meet the requirements of The National Sanitation Foundation (NSF Standard 61) for drinking water additives. This material has also been approved for use with Drinking Water, Potable Process Water and Brine Solution. No matter how small or large, easy or complex, Hitech Rubber Industries can provide a lining system for your reservoir.
Reservoirs Liners can be used to hold almost any type of liquid so the liner system must be resistant to all the likely chemicals.
Mostly reservoir uses make protecting the liner difficult, a strong liner that is resistant to ultraviolet light (UV) and ozone as well as being able to deal with the full range of ambient (and liquid) temperatures is required. As a result storage reservoirs can be lined with any of the geomembranes.
EPDM(ethylene propylene diene monomer) exhibits high tensile strength and excellent resistance to punctures, UV radiation, weathering and microbial attack. EPDM(ethylene propylene diene monomer) is highly flexible material with a low co-efficient of thermal expansion and contraction, enabling it to lay flat in a wide range of temperatures and terrains thereby conforming well to irregularities in the sub grade. EPDM is manufactured and installed as liners, caps and covers in environmental containment applications worldwide.
EPDM(ethylene propylene diene monomer) exhibits excellent elongation characteristics and does not require a soil cover. EPDM is delivered to the project in panels that are up to 50' x 200' (10,000 sq .ft.) This product is available in custom sizes as well.
Uses of EPDM(ethylene propylene diene monomer) :-
Pond liners need to be protected from sharp objects (for example, stones) below the liner and from being punctured by any objects in the water body. Protection can be provided with layers of sand, concrete, fiber-matting and other materials. Pond liners are manufactured in rolls. Strips of liner can be seamed or welded together on site which can have their panels pre-fabricated together in the factory to fit the design shape of the pond.The edge of the pond liner can be rolled over and secured in a trench or it can be fixed to a vertical wall made in brick or concrete. Box-shaped pond liners can be made for rectangular structures. EPDM is the most popular at the moment due to cost. A newer method involves a spray-based coating known as polyurea and though the cost of using polyurea is considerably higher than flexible sheets, the lifespan of the material may be much longer than any other. The oldest material used for pond liners are made of clay which can be spread and mixed directly into soil to seal a pond. Clay has the longest life span of all pond liners due to its inert mineral composition that can remain stable for thousands of years .
