  • 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 ...

  • 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 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 Installing Arsenic Drinking Water Treatment Can Save Your Life

    Arsenic is an element so associated with its toxicity and harmful effects on the human body that the word itself is often used for any kind of general poison. While the exact ways that exposure to the metalloid attacks various organs and systems is still not fully understood, studies throughout the scientific community are continually determining that ingesting arsenic through drinking water can ...

  • 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 ...

  • Using Biological Filtration to Remove Arsenic from Drinking Water

    In 2001, the U.S. Environmental Protection Agency changed the standards for arsenic levels in drinking water. At that time, the agency had estimated that more than 36 million Americans were drinking water that contained arsenic levels at or above 3 parts per billion. A new standard was set, lowering the maximum contaminant level to 10 parts per billion (ppb) from the previous standard of 50 ppb. ...

  • 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 ...

  • What You Should Know about Arsenic Treatments

    The nutrients that you put into your body directly impact your health. If you consume water with harmful substances, bacteria, or metalloids, it could create serious issues. While not a metal, arsenic is considered a metalloid because it contains many of the same properties as metallic elements. Typically found in soil, arsenic is harmful when ingested. Unfortunately, many Americans unknowingly ...

  • 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 ...

  • 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 ...

  • Reduction in exposure to arsenic from drinking well-water in Bangladesh limited by insufficient testing and awareness

    This study considers potential policy responses to the still very high levels of exposure to arsenic (As) caused by drinking water from shallow tubewells in rural Bangladesh. It examines a survey of 4,109 households in 76 villages of Araihazar upazila conducted two years after a national testing campaign swept through the area. The area is adjacent to the region where a long-term study was ...

  • Adsorption characteristic of As(III) on goethite waste generated from hydrometallurgy of zinc

    In this paper, goethite waste from hydrometallurgy of zinc was used as a raw material for arsenic adsorbent preparation. The goethite waste adsorbent (GWA) was characterized with scanning electron microscope (SEM), X-ray powder diffraction (XRD), and particle size distribution analysis. The adsorption of As(III) on GWA was studied as a function of contact time, pH, and coexisting anions. The ...

  • Adsorption of arsenic from drinking water using natural orange waste: kinetics and fluidized bed column studies

    The biosorption potential of orange waste (OW) was investigated using synthetic solutions of arsenic and contaminated drinking water under different parameters, e.g. biosorbent dose, initial concentrations of solution, contact time, and pH in a batch system. The optimum conditions were identified as a contact time of 30 minutes, pH 6, biosorbent dose of 1 g L−1, and initial arsenic ...

  • The binding of metal ions to molecularly-imprinted polymers

    Imprinting polymerization is a flexible method to make resins specific for different compounds. Imprinting polymerization involves the polymerization of the resin in the presence of a template, here cadmium ions or arsenate. The template is then removed by washing, leaving specific binding sites in the resin. In water treatment, the removal of toxic metal ions is difficult due to the limited ...
