  • 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 ...


  • 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.

  • 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 ...

  • 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 ...

  • The costs of small drinking water systems removing arsenic from groundwater

    The US Environmental Protection Agency (EPA) conducted an Arsenic Demonstration Program whereby the Agency purchased, installed, and evaluated the performance and cost of 50 small water arsenic removal treatment systems in the USA. A major goal of the program was to collect high-quality cost data (capital and operational and maintenance (O&M)) from the long-term operation (1–4 ...

  • Project (in process) - thunderbird farms - Arizona arsenic & fluoride removal

    Background In 2008 AdEdge was selected by Atwell Hicks Engineers and Thunderbird Improvement district to provide a 500 gpm treatment system for this Arizona community serving 1,500 population to treat elevated levels of arsenic and fluoride. Non compliant levels are 13 ppb As and 3.20 mg/L F respectively. Raw water quality information is provided in the table below. Several options were ...

  • The effect of co-existing solutes on arsenate removal with hydrotalcite compound

    Hydrotalcite (HTAL-Cl), an inorganic anion exchanger, is of use as an adsorbent for the removal of arsenate (As(V)) in water systems. The adsorption properties of HTAL-Cl for As(V) and the effects of co-existing anions on the As(V) removal performance were investigated in this work. Under the conditions of pH≥4, the adsorption capacity for As(V) gradually decreased with an increase of pH, but ...

  • Removal of arsenic from an aqueous solution by pretreated waste tea fungal biomass

    Arsenic exists in natural waters both in inorganic and organic forms. The inorganic form of arsenic is more toxic compared to its organic form. Inorganic arsenic is the predominant form in contaminated groundwater. Arsenic exists in two,oxidation states: arsenite, As (III) and arsenate, As (V) (Pokhrel and Viraraghavan, 2006). It is introduced in the aqueous system through geochemical reactions ...

  • San Joaquin Valley California - Arsenic removal from ground water

    Background The San Joaquin Valley of California is approximately 220 miles long and varies in width to a maximum distance of approximately 80 miles. The occurrence of groundwater over the entire extent of the valley is abundant. Recharge for the varied depths of aquifers is from precipitation in the form of rain and the snow pack from the western Sierra Nevada Mountain Range. High ...

  • Arsenic removal by ferric-chloride coagulation – effect of phosphate, bicarbonate and silicate

    Jar tests with synthetic water were carried out in order to investigate the effect of phosphate, bicarbonate and silicate on arsenic removal efficiency by in-situ formed ferric hydroxide. Above 12 mg C/L inorganic carbon concentration, the adverse effect of bicarbonate was definite, and resulted in higher remaining arsenic concentration. At all pH values (7.5–7.8) and coagulant dosages (0.84–3.00 ...
