  • Arsenic Removal

    The Arsenic Removal ProcessArsenic, a naturally occurring element, is found throughout the environment; for most people, food is the major source of exposure. Acute (short-term) high-level inhalation exposure to arsenic dust or fumes has resulted in gastrointestinal effects (nausea, diarrhea, abdominal pain); central and peripheral nervous system disorders have occurred in workers acutely ...


  • How to Treat Water and Remove Arsenic

    Arsenic is a naturally occurring element from the earth’s crust. Around the world, many countries have groundwater that is steeped in arsenic. Until recently, governments haven’t realized just how bad arsenic was for people, even in minute concentrations. In 2001, the US Environmental Protection Agency felt it necessary to lower the drinking water arsenic standard from 50 parts ...

  • Plant algae method for arsenic removal from arsenic contaminated groundwater

    Field studies were carried out in Urumqi River Basin in Northwest China. The study focused on experimentation on a plant algae method that was tested by taking various water chemistries into consideration. The results from a greenhouse experiment evaluated for four doses of P (0, 100, 200, and 300 μmol/L) using two ferns (30 and 60 day old) on 15 L of contaminated groundwater per plant revealed ...

  • Airport Lead and Arsenic Removal - Case Study

    City of Cincinnati The Airport was built on a former military firing range and apple orchard. To complete the removal of all the lead and arsenic, we excavated and removed over 20,000 tons of treated and non-treated contaminated soil. Then we stabilized 11,000 tons of hazardous soil on site. We graded and capped the site all while complying with FAA, City and Airport ...

  • Solutions for removing arsenic from drinking water

    Arsenic, a metalloid element, is found in many naturally occurring compounds. In its inorganic form, arsenic is toxic. Arsenic occurs naturally in some groundwater supplies worldwide, including in the drinking water supplies in parts of Taiwan, Japan, Bangladesh, and western South America. This is causing health problems, according to the American Cancer Society. Albuquerque, New Mexico, is the ...

  • Guide to Removing Arsenic from Drinking Water

    It’s said that the human body is made up of almost 60 percent water. Is the water you’re putting into your body pure? Many people are unaware of the chemicals and compounds that are seeping into their drinking water and wreaking havoc on their internal systems. Arsenic, for example, can be found in many different areas. In the Northeast especially, well water is more likely to be ...

  • Understanding the 3 Types of Arsenic Removal Used for Wastewater

    With the onset of the Industrial Revolution and the development of internal combustion engines and new manufacturing technologies, fresh water became an essential raw material not only for production, but for cooling purposes in manufacturing processes. However, when fresh water is used in an industrial process, it creates industrial wastewater composed of a variety of chemicals and other raw ...

  • Brown City Michigan SORB 33 Arsenic Removal

    Site Background The City of Brown City, Michigan located about 60 miles north of Detroit, was awarded the first of the US Environmental Protection Agency’s (EPA) treatment systems as part of the EPA Arsenic Removal Demonstration Program in June 2003. The EPA and its team of consultants on the Demonstration Program panel selected Severn Trent Services’ SORB 33® arsenic adsorption system for use ...

  • Effective Techniques for Arsenic Removal from Water

    Arsenic is a tricky substance because it is colorless and odorless, making detecting its presence and ensuring its removal at a contaminant site tricky. However, high levels of arsenic can have drastic, fatal effects on wildlife as well as humans if left untreated. If it isn’t properly and fully extracted, serious problems can result. If you’re considering the best industrial ...

  • The 5 Benefits of Professional Arsenic Removal from Water

    It is a sad and scary truth, but many homes have arsenic in their water systems. High levels of arsenic can be dangerous to you, your family, your pets, and the property you inhabit. Do not panic, though. Simply research an arsenic filtration system. There are many advanced methods that can be used to remove arsenic from water. Arsenic in water removal is completely affordable and safe. ...

  • Arsenic(III) removal by adsorption on sawdust carbon

    Studies on the removal of As(III) by adsorption on sawdust and sawdust carbon have been carried out at room temperature (25 ± 1°C). The adsorption isotherm of As(III) on sawdust carbon was obtained in a batch reactor. The process of uptake follows the first-order adsorption rate expression and obeys the Langmuir and Freundlich model of adsorption. The mass transfer coefficients as a function of ...

  • How Arsenic Is Removed from Drinking Water

    Drinking water is a vital and life-giving resource. Clean and filtered drinking water keeps you healthy and safe from harmful chemicals that can immediately harm you or slowly damage your body. That is why arsenic removal from drinking water should be handled by professionals, and it should be done to all possible sources of water that supply homes and businesses. Those who are dedicated to ...

  • Removing Inorganic Contaminants with Arsenic Water Treatment

    Inorganic contaminants in drinking water are more than just an annoyance. Arsenic is a naturally occurring carcinogen, which is known to lead to both cancer and heart failure. Arsenic is also a difficult contaminant to detect. Since arsenic is both odorless and colorless, testing has to be conducted in order to reliably identify it. Arsenic often appears in conjunction with iron and manganese. ...

  • Arsenate removal using a combination treatment of precipitation and nanofiltration

    A combination treatment of Ca-precipitation and nanofiltration membrane was studied to remove arsenate from water. The selected nanofiltration membrane was an amphoteric charged membrane, proved by the results of ATR-FTIR spectra and zeta potential. The arsenate and calcium removal efficiencies had the lowest values at the isoelectric point of the nanofiltration membrane, attributed to the ...

  • Efficacy of arsenic filtration by Kanchan Arsenic Filter in Nepal

    Groundwater arsenic contamination has caused a significant public health burden in lowland regions of Nepal. For arsenic mitigation purposes, the Kanchan Arsenic Filter (KAF) was developed and validated for use in 2003 after pilot studies showed its effectiveness in removing arsenic. However, its efficacy in field conditions operating for a long period has been scarcely observed. In this study, ...

  • An assessment on Spirulina platensis as a biosorbent for arsenic removal

    A column consisting of algal biosorbents like agar-agar, alginic acid, calcium alginate and Spirulina platensis biomass entrapped in polyurethane foam matrix was designed and tested for the removal of As(V) from the aqueous medium. The performance of the column was studied in terms of removal efficiency, metal sequestered in the column during a specified time and biosorption capacity. The ...

  • Evaluation of biofilter performance to remove dissolved arsenic: Wood Cadillac

    The Wood Cadillac mining site, in north-western Quebec, is an important source of arsenic contamination. The arsenic-rich effluent is treated through a reductive biofilter, which allows arsenic to precipitate as a sulphide (likely As2S3). The top-fed biofilter, built at the end of 1999, is 50 m x 57 m by 1 m thick. The reducing conditions are provided by the decomposition of yellow birch bark ...
