The United States Environmental Protection Agency has set forth rules that regulate contaminants found in public water systems. The agency has established Maximum Contaminant Levels, Maximum Contaminant Level Goals, monitoring requirements and the best technologies for contaminant removal. A company that specializes in water treatment solutions offers a variety of methods that are effective for arsenic in drinking water treatment. The Oxidation Method Oxidation is a very effective solution if you are looking to clean water that is sourced from natural wells. Oxidation uses chemicals to make soluble pollutants insoluble, thereby reversing the process by which they originally dissolved into ground water. Coagulation Filtration Through the coagulation filtration process, a coagulant such as aluminum salt is used to pretreat water that has been contaminated. This type of arsenic in drinking water treatment allows for higher flow rates, creates less backwash water than more traditional treatments, offers lower operating costs and has a life of about 10 years before replacement is needed. The Adsorption Treatment Along with nitrates, iron, manganese, hydrogen sulfide and ammonia, arsenic is one of the most common inorganic contaminants to be found in drinking water. The adsorption process causes contaminants to break away from water molecules. Water flow is directed through pressure vessels that contain filter media, which attract the free-flowing contaminants. Studies have shown adsorption to be the highest-performing technology in the removal of arsenic from water. Choosing the Right Way to Go Knowledgeable water treatment specialists can recommend the right arsenic in drinking water treatment for your needs. The solution will be predicated on flow rates, arsenic concentration and the presence of other contaminants as well as any site limitations that might exist. Also available are modular treatment systems that can be installed onsite and incorporate the oxidation, adsorption or coagulation-filtration processes. The most effective water treatment solution will also meet the Chemical Contaminant Rules established by the Environmental Protection Agency.
