Siemens Water Solutions offers a complete line of products to remove oily contaminants from water, including the Monosep high-flow walnut shell filter which offers improved technology in walnut shell filtration. The proprietary filter design requires no moving equipment to perform backwashes, and greatly reduces the volume of backwash water produced when compared to other walnut shell filter designs. This simplifies the design of the filters, reduces the weight and footprint, and lowers the cost of multiple filter systems.
