What is an injection?

Injector is a machine that transports or injures liquid waste into the ground. Different countries have different regulations for injection wells. Less developed countries such as Mexico have fewer regulations compared to countries such as the United States (US), Great Britain) and Norway. There are five types of injection wells, marked by I-V classes.

The injection wells are relatively cheap because they require small or no preliminary waste treatment before disposal. The injection well consists of pipes that force waste to underground and are lined with cement and sealed on the surface to prevent leakage. Inside the cement case is a real injection tube. This tube can be sealed on the bottom to prevent the injected waste material to prevent. Despite these measures, it is still possible for waste to leak into drinking water and long -term effects of waste disposal are not known.rdous and nonhazarous materials such as fuels, pesticides and explosives. In the US, their use is regulated by lawM o sources, protection and recovery (RCRA). Injections can only occur at depths of greater than 4,000 feet (1,219 m) and rock formations that are used as injection sites must be isolated, so there is only little chance that the waste material seep into drinking water. They cannot be placed in areas that have a history of seismic activities.

Class II injection wells are used to dispose of waste associated with oil and gas production. Generally, hydrocarbons are injected into the ground. In the USA, class II injections have been used since the age of 30.

It is used for collection rather than disposal, class III injection wells are used in mining. These holes inject and then load, water or overheated steam into the ground to extraction minerals. There are two types of extraction. Solution mining usually extracts salt or sulfur by dissolving or melting the substance in the injected water. Extracts in situ PRIMary uranium by injection of non -toxic substances into a rock that breaks and dissolves minerals.

For strictly dangerous and radioactive material, the

IV injection wells are used. Scientists have found that this type of injection has a high risk of contaminating drinking water. Subsequently, they were banned in the US, Norway and several other countries.

The most common type of injection holes is the class V. Class vs. He releases gravity to Aquifers. Typical examples of class V injection are septic tanks and drainage wells. This type of well injection is essentially safe. However, incorrect maintenance can cause backups that flood lawns and other areas with wastewater.
