Arsenic content in groundwater is often the result of deep well drilling into contaminated water tables. Elevated levels of the toxin can also be caused by industrial seepage. Many water supplies in the United States and internationally have higher level of arsenic content than is recommended by health and environmental control agencies, such as the World Health Organization and the Environmental Protection agency. This means that every well is a potential health hazard. Arsenic drinking water treatment technology is necessary to make this tainted substance into a safe supply for household or commercial use. Health and Business This metal becomes an issue for various businesses and organizations because it puts the consumers of the water supply at risk for various chronic problems. Inorganic arsenic is a known human carcinogen. It also causes various types of maladies in several internal organs overtime. Although there is an accepted maximum level of arsenic and water and that is mandated by government agencies, it's generally held that there is no acceptable level of consumption of this toxin in terms of human health. Beyond issues of health, compliance with standards is an important element of consideration when you're looking at installing arsenic drinking water treatment systems. There are various applications and technologies available to suit the needs of your businesses and the requirements of your local jurisdictions. Adsorption Adsorption technology uses granular media, such as iron oxide pellets, in order to electrochemically attract heavy metal ions. With these types of systems, arsenic is bonded chemically to adsorption media as long as incoming water pressure is maintained at a prescribed level. Over time, the iron media becomes spent, requiring replacement. One of the major benefits of this type of system is that the byproduct can often be disposed of the same way you would handle any other type of solid waste. Oxidation There are many types of operations that benefit from and even require arsenic treatment solutions. Private well owners might find a benefit in a wellhead treatment system such as the combination of oxidation and filtration process. These remove various minerals such as arsenic, iron, hydrogen sulfide and manganese. This type of system is ideal for well operators who desire to comply with secondary standards and increase water quality for drinking. Coagulation Another primary treatment technology utilizes a coagulation method of mineral removal. The coagulation type of system creates minimal backwash and is a largely automated process. These systems reduce overhead costs of operating your arsenic removal system compared to other alternatives, both in terms of labor budgets and rent. It works by introducing pretreatment chemical that speeds up the process of filtration, making these types of applications good for high volume systems that require increased efficiency and responsiveness. They are also adapted to a wider operating range, in terms of differential pressure and operating temperature. Choosing the right application might require some advanced predictions and modeling, so make sure you have all the facts. Each arsenic drinking water treatment method is different in terms of capacity, effectiveness and scalability. You also face different operating costs and training requirements based on which machinery you choose. Contact a company that manufactures or sells this equipment to get a full overview and technical specifications of each treatment technology.
