  • 3 Water Utilities that Lowered their Arsenic Levels with AdEdge

    Finding an appropriate solution to address arsenic in raw water can be challenging for utilities. Studies have shown that when ingested in high concentrations, it is linked to cancer in the skin, lungs, bladder and kidney, and can cause significant skin changes, such as thickening and pigmentation, as well as other health issues. For this reason, the ...

  • Separate As(V) from solution by mesoporous Y-Al binary oxide: batch experiments

    Contaminant arsenic(V) has been regarded as one of the top-priority pollutants to remove from water. In this contribution, different mesoporous Y-Al binary oxides were prepared by the wet impregnation method via varying the molar ratio of Y/Al in the range of 0.029 to 0.116. The manufactured materials were employed as adsorbent to separate arsenic(V) from water. The adsorbent was characterized ...

  • 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. ...

  • Extensive Solutions for Removing Arsenic from Your Drinking Water

    You may not be aware that your water supply has unsafe levels of arsenic in it. If testing proves this to be the case, you must immediately find a form of arsenic water treatment to help you have access to clean drinking water again. Arsenic is a poisonous substance that has innumerable negative health effects on humans. There are several methods of performing arsenic removal from ...

  • How Arsenic Biological Filtration Systems Can Improve Your Life

    Water is the foundation of human existence. It’s used for cooking, bathing, cleaning, and most importantly, drinking. Unfortunately, water is often dirty and contaminated, especially when it’s pulled from groundwater sources and wells. Since many cities have been shown to have low-grade drinking water, concern has increased about water quality. Many people are wondering if their water ...

  • 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 ...

  • How to Deal with Arsenic in Drinking Water

    Thanks to recent developments in technology, daily drinking water undergoes a rigorous treatment process for water to be consumable. This is because most ground and natural river waters have a chemical in them called arsenic. Arsenic is a metallic chemical element that is found commonly among rocks and sulfur in the Earth’s crust. Arsenic is known for getting into your drinking water from ...

  • 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 ...

  • Determinants of the use of alternatives to arsenic-contaminated shallow groundwater: an exploratory study in rural West Bengal, India

    Shallow groundwater containing toxic concentrations of arsenic is the primary source of drinking water for millions of households in rural West Bengal, India. Often, this water also contains unpleasant levels of iron and non-negligible fecal contamination. Alternatives to shallow groundwater are increasingly available, including government-built deep tubewells, water purchased from independent ...

  • Dynamic desorption of arsenic from polymer-supported hydrated iron(III) oxide in a wastewater treatment plant

    Polymer-supported hydrated iron(III) oxide (PHIO) was successfully applied as adsorbent for arsenic removal in a wastewater treatment plant in Nandan, China. The practical PHIO adsorbent samples (PHIO-P) were collected from the adsorption column of the wastewater treatment plant, and desorption experiments of the adsorbent were carried out. Our results showed that the formation of precipitates ...
