Arsenic Treatment Plants

Arsenic is a naturally occurring element that is present in the environment and even in the human body. In safe amounts, it does not cause any damage and cannot be detected because it is tasteless. The US drinking water standard considers 10mg/L of arsenic in drinking water safe for consumption.

However, if the levels go beyond this, people can experience skin problems, blood circulation issues, and can even be at risk of cancer. At Herback General Engineering, we have worked with local subcontractors in Nevada, Arizona, and California to build several water arsenic removal plants along with the Western United States. 

Arsenic Removal from Water

There are several ways to remove unsafe concentrations of arsenic from water and bring them down to relatively safe levels. The most used methods include:

• Lime Precipitation – This process can be used to reduce high concentrations of arsenic in a water body. For example, if the concentration is around 100mg/L, the process can bring it down to between 1 to 5mg/L. It is relatively common to use a new process to reduce arsenic concentrations further.
• Oxidation – In this process potassium permanganate, hydrogen peroxide, or ozone are used to convert the A³⁺ or arsenite compound into an A⁵⁺ arsenate compound. The latter is easier to filter using precipitation or absorption techniques.
• Coagulation and Precipitation Process – This is the most affordable method commonly used by clients who are on a tight budget. It involves using a combination of chemical and physical processes to remove arsenic from water. Chemical coagulants like alum or iron salts are used first before the treated water is sent through a thorough multimedia filtration process.
• Biological Processes – Many businesses and communities have started using organic techniques for arsenic removal from groundwater and other natural water bodies. This process is highly effective in removing arsenic as well as other harmful components like mercury, selenium, or nitrate.

Other arsenic removal methods include ion exchange, reverse osmosis, and adsorptive media. All these solutions are highly effective, helping bring down arsenic levels enough for human consumption.
