Arsenic Removal Using the Iron Breaker

Writer's picture: Scott BrittonScott Britton

When it comes to co-precipitation media for arsenic removal using the iron breaker oxidation process, there are a few effective options you can consider. Here are some commonly used co-precipitation media: 1. Ferric Chloride (FeCl3): Ferric chloride is often used as a coagulant in the iron breaker oxidation process. It forms iron hydroxide precipitates that can effectively adsorb arsenic from water. 2. Poly Aluminum Chloride (PACl): PACl is another coagulant commonly used in water treatment processes. It can aid in the co-precipitation of arsenic with iron hydroxide precipitates. 3. Aluminum Sulfate (alum): Alum is a widely used coagulant that can be combined with ferric chloride to enhance the co-precipitation of arsenic. It forms aluminum hydroxide precipitates that can help in arsenic removal. 4. Lime (Calcium Hydroxide): Lime can be used in conjunction with ferric chloride or PACl to adjust the pH of the water. It can help in controlling the solubility of arsenic and promote its co-precipitation with iron hydroxide. 5. Sodium Hydroxide (Caustic Soda): Sodium hydroxide can be used to raise the pH of the water, which can enhance the co-precipitation of arsenic with iron hydroxide precipitates. It's important to note that the selection of co-precipitation media may depend on the specific water conditions, including pH, concentrations of arsenic, and other water constituents. Hambly Water Conditioning can recommend and facilitate laboratory tests, performed by a third part lab to determine the most suitable co-precipitation media for your specific application.
