Technology for arsenic removal from water, wastewater and groundwater | |
Oxidation | This method [e.g. air Oxidation by ozone; chemical oxidati on by gaseous chlorine, hypochlorite, permanganate, hydrogen peroxide, or potassium permanganate, and Fe(II), Mn(II)] is very effective in removing the pentavalent form of arsenic (arsenate) via arsenite to arsenate conversion. Oxidation must be coupled with a removal process such as coagulation, adsorptition or ion exchange. Oxidation is a very slow process, which can take hours or weeks to complete. An atmospheric oxygen, hypochlorite, and permanganate is the most commonly used technology indeveloping country. |
Precipitation/Coprecipitation | This system is frequently used for the treatment of arsenic-contaminated drinking water and groundwater as well as wastewater originati ng from the metallurgical industry. This technology uses chemicals to transform dissolved contaminants into an insoluble solid or form another insoluble solid onto which dissolved contaminants are adsorbed. The solid is removed from the liquid phase by clarification or filtration. The method is associated with a simple operation system and the availability of sorbents, which in this case are ammonium sulfate, manganese sulfate, copper sulfate, sulfide, ferric salts (e.g. ferric chloride, sulfate and hydroxide), alum (aluminum hydroxide) and calcium hydroxide. The sulfide precipitation is the most widely used technology. |
coagulation-Flocculation and filtration | It is based on the addition of a proper coagulant (alum, ferric chloride or ferric sulfate) to contaminated water. After that, the water is sti rred, allowed to settle, and filtered for best results. coagulation with ferric salts works best at pH below 8, while with alum – at a pH range of 6–7. The production of high amounts of arsenic-concentrated sludge is disadvantage of coagulation-flocculation, which requires a costly treatment of waste. Therefore, this process is not so common as the other methods. |
Ion-Exchange Resins | The syntheti c materials (ion exchange resins) are applied to remove some compounds from water as well as for water softening. These resins mostly remove arsenate, therefore the raw water with arsenite should be oxidized first. The amount of water that can be treated is largely independent of arsenic concentration and pH. |
Activated Alumina | This commercially available method is based on the use of acti vated alumina, which works better in slightly acidic environment (pH 5.5 to 6). For best results, raw water with arsenite should be oxidized before treatment. |
Membrane methods | This method is based on the reverse osmosis and nanofiltration. For this purpose, synthetic membranes are used, which are water permeable but reject larger molecules, including arsenic, chloride, sulfate, nitrate and heavy metals. Reverse osmosis also effectively removes other constituents from water (e.g. organic carbon, salts, dissolved minerals, and color). This treatment process is relatively insensitive to pH. |
Other technologies | They are less documented. Some of the technologies are sti ll under development, e.g. low-tech iron-coated sand and greensand, novel iron-based sorbents, aeration and sedimentation, and specially engineered syntheti c resins. |
Technology for arsenic removal from soil/sediments and other waste | |
Solidification/Stabilizatition | It physically binds or encloses contaminants within a stabilized mass and chemically reduces the hazard potenti al of waste by converti ng the contaminants into less soluble, mobile or toxic forms. |
Vitrification | High temperature treatment that reduces the mobility of metals by incorporati ng them into a chemically durable, leach-resistant, vitreous mass. The process reduces the concentration of compounds in soil and waste. |
Soil Washing/Acid Extraction | The ex situ technology that uses the behavior of some contaminants to preferenti ally adsorb onto fine soil/sediment fractions. The soil/sediment is suspended in a wash solution and the fines are separated from the suspension, thereby reducing the contaminant concentration in the remaining soil. |
Biological treatment | It involves the use of microorganisms that act directly on contaminant species or create ambient conditions that cause the contaminant to leach from soil/sediment or precipitate/co-precipitate from water. |
Electrokinetic treatment | The usage of current and electrodes for soil/sediment. The current is applied to soil to mobilize contaminants in the form of charged species. Contaminants arriving at the electrodes can be removed by electroplati ng or electrodeposition, precipitation or co-precipitation, adsorption, complexing with ion-exchange resins, or by pumping water (or other fluid) near the electrode. |
Phytoremediation | It involves the use of plants to degrade, extract, contain, or immobilize contaminants in soil, sediment and groundwater. |
In situ soil flushing | It extracts organic and inorganic contaminants from soil/sediment by using water, a solution of chemicals in water, or an organic extractant, without excavati ng the contaminated material itself. The solution is injected into or sprayed onto the area of contamination, causing the contaminants to become mobilized by dissolution or emulsification. After passing through the contamination zone, the contaminant-bearing flushing solution is collected and pumped to the surface for treatment, discharge or reinjection. |
