F.B. Leopold, a Xylem brand Leopold® Performance Filters

The Leopold® performance filter is a rapid gravity flow granular bed filter designed and engineered to achieve specific performance requirements of individual municipal and industrial water treatment plants. It is a filter built for performance, based on performance. A Leopold filter is planned based on upstream and downstream process conditions. Each aspect of the Leopold filter — filter media, backwash, controls — is tuned to achieve maximum rate of filtration at the longest possible cycles. But more importantly, Leopold filters are designed and engineered to achieve optimum net production per square foot per day at high filtration rates.
