What are the different types of remediation devices?
Remediation equipment includes a wide range of machines used to remove contaminants from soil or groundwater. Types of remediation equipment include Earth migrators such as bums and bulldozers, trucks or railway cars, liquid pumps, aeration and sparging machines, filter equipment and combustion systems such as rotary furnaces and infrared fire. Several types of devices can be used together for large -scale projects. Climbers and bulldozers move heavily contaminated material to the lined retention area, preventing further leaching of contaminants to the ground. In some cases, it is decided to remove contaminated soil and out -of -place treatment. The use of the device is used soil to dig into trucks or railways for transport elsewhere.
For axle contaminated liquid, most often water, pumping is necessary to move water to or over other nursing equipment or back to the ground or storagereservoirs. If the liquid is built from the treatment site, the pumps are used to move to trucks or railways for sending. Many healing methods relies on the exposure of contaminated groundwater of air and pumps are also required to achieve this goal.
The introduction of forced air into the soil or water may cause release of volatile pollutants into the air. Spargers inject air bubbles into lower levels of contaminated water or soil, so rising air can carry volatile compounds to the surface. The aeration or stripping of air moves through contaminated water into towers or trays where it spreads to expose as much air surface surfaces as possible. Testing equipment for air streaming can be used as packaged towers, spray units and diffusers.
particle impurities can be removed using a filter device. Using a porous medalIA or membranes are captured particles that cannot fit through the holes in the filter medium. The degree of filtration depends on the size of the particles that can pass through the filter medium or membrane.
Remediation equipment for combustion processes of solid substances contaminated with volatile organic compounds such as oil products. The rotary furnace burns volatile materials in a rotating cylinder equipped with consecutive and the method for capturing and cleaning the exhaust gases such as a house with a bag or washing machine. Infrared combustion is done by electrically driven silicon carbide rods at very high temperatures. The contaminated materials move along the transport belt to pass through the radiant heat from the rods and burning flammable components.
The remediation of a large site may take years and include technology variety. Some remediation devices, such as aerates and spargers, work very well to clean soil and water and may require several therapeutic cycles. Other options such as filtrationAnd combustion is effective only after a single treatment, although they are not suitable for all pollutants.
