Carbon filters are commonly used for water purification, removing contaminants, taste and odor from drinking water. This system consists of two 3,200-gallon stainless steel tanks that are dairy/pharma-grade polished (150 grit).? Built to meet ASME code, each tank stands over 16-feet tall and is equipped with a top multi-lug manway and a flanged and bolted side manway with davit arm for ease in operation.? For cleaning, each tank utilizes two removable CIP spray balls. The tanks and double-header assembly were built and fit-up in our shop, then shipped loose for field installation.
