Inquiry (采购产品): Custom application - arsenic Our utility recently inherited a small water system with elevated levels of iron, manganese, and arsenic. The previous owner had installed a small anthracite/sand filter for iron and manganese removal. We have no plans or drawings of the filter and are going to replace the media. We would like to optimize the filter for additional arsenic removal. We will be adding 10-20 mg/L of iron to reduce the arsenic. Can you recommend a filter media profile and media grades/sizes for this type of application? The filter loading rate is 5 gpm/ft2 and the backwash rate is about the same. Can you ship to Reno, NV?
