Filtering tryhlaretylen (TCE) of water

What is TCE?

Tryhloretylen (TCE) is classified as aliphatic galageniravanae organic compound. TCE – is a colorless, non-flammable liquid. Due to its unique treatment properties and solvent TCE is widely used in manufacturing, industrial cleaning solvents, paint removers, as well as "universal" abyastlushchvalnik more than 50 years. TCE is also used for cleaning of cotton and other textile fabrics. It is used in pharmaceutical industry as a solvent for waxes, fats, oils and resins, as well as in the aerospace industry. Many consumer products, such as correcting fluid, paint paint strippers, glues and stains to remove, contain TCE. TCE is considered relatively harmless and has been disposed of in landfills and in places of chemical waste. Improper practice of recycling and diversion of containers for storage also led to contamination of groundwater. In California alone around 161.315 pounds TCE was released into the environment. TCE – is the most frequently detected volatile organic chemicals (VOC) in the groundwater in the USA. In the state of New Jersey study, approximately 20% of the 315 wells tested was contaminated with TCE, and / or other Los above detection limits 1 ppm. TCE contamination has led to the closure of water supply wells on Long Island, New York and Massachusetts. Determining the level of at least one of 18 VOC, including TCE, it was found in 15.9% of the 63 wells of water in the sample taken in Nebrastsy.

TCE and health hazards

The study of biological cancer research, conducted by the National Cancer Institute (later the National Toxicology Program), has shown that the impact of tryhloretylenu with & # 39 is carcinogenic in animals that produces liver cancer in mice and kidney cancer in rats. Recent studies in laboratory animals and observations in human populations indicate that exposure tryhlaretylenu may be associated with congenital heart disease. The National Toxicology Program in the 11th report on carcinogens tryhloretylen classifies as "reasonably provided human carcinogen" based on limited evidence kantserogennastsi studies in humans and sufficient evidence kantserogennastsi studies in experimental animals. Drink or inhibit water contaminated with TCE, it causes a lot of health problems. TCE is rapidly absorbed into the blood after inhalation and ingestion, and it is rapidly distributed to organs, including liver, kidney, cardiovascular and nervous systems. Number of TCE, which is considered a health risk depends on many variables such as the amount of water a person drinks, their size, age and other health conditions, such as immune status. It may be an increased risk to health for the most exposed and sensitive people.

TCE and contamination of drinking water

TCE can rapidly penetrate the soil with rainwater and enter the groundwater. TCE can adsarbavatstsa on soil particles above the underground water reserves. If groundwater cut through soil contaminated u e, it picks up the solvent. Wastewater treatment systems or municipal water systems, using standard methods, which include coagulation nozzle sedimentary softening, filtration and chlorination particles ineffective for reducing the concentration of TCE to the "dangerous" level. TCE contamination can be found in wells and municipal water supply. Agency US Environmental Protection established the maximum allowable level of TCE in drinking water at a level of 5 ppm (parts per billion). Many people probably are not exposed to this chemical kantserogennaga at any level. Fortunately, there are several steps you can take to reduce you and your seven & # 39; and & # 39; the impact of TCE.

How to protect yourself from the TCE contamination in my water?

A well-designed water filtration system to remove TCE. However, not all filters for water this solvent is removed. filters using granular activated charcoal cartridge (GAC) or solid carbon block & # 39 is the best method for removing TCE from a water supply. The type of filter is best suited for you should be based: the amount of water you use, the availability of space and plumbing access and whether you want to protect from the effects of a couple of TCE.

There are two types of filter systems for the removal of TCE:

1. Filters (POU), working with water to a sink or shower.

2. Complete home filtration (POE), which handles all of the water that enters the building, not only water from a sink or device. POE filter system typically consists of a preliminary filter and a granular activated carbon filtration.

For a simple TCE TCE protection input is recommended to use a filter countertops. This small single filter cartridge protects the particles, flavor, odor and TCE. The filter is installed on your tap and provide purified water for drinking and cooking. Plumbing is not required. To protect against TCE vapors use a filter for the shower. Shower filter contains high-grade activated carbon, which will protect you and your things & # 39; nd from breathing vapors and skin exposure TCE. Shower filter is installed easily. Just Screw it into an existing shower.

The most complete and effective way to protect against TCE and other organic pollutants – a filtering system activated carbon in the whole house. Filtration systems provide a whole house filtered water for each tap and the shower device using water in your home or business. All the water that comes into your home or business, passes through the activated carbon, removing TCE and other organic chemicals that cause taste, smell and health.
