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.
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 down-stream 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.
Leopold filters can be designed with a center-flume, front-flume, H-flume or the latest Leopold Flat Bottom Flume™ Filter configuration. The Leopold Flat Bottom Flume Filter allows substantial cost savings in excavation and support structures.
Media Designed to Clean the Water
The filter media in a Leopold filter — media quality, bed composition, bed depth, and grain size distribution — is designed according to filter configuration, raw water quality, pretreatment, and desired filtrate quality. Leopold filters employ Engineered Filter Media® anthracite, the lowest uniformity coefficient (UC) anthracite filter media available. Leopold Engineered Filter Media anthracite typically produces consistent improvements in turbidity removal due, in part, to more efficient solids loading. Plus, low-UC media produces smaller changes in effluent turbidity during periods of peak influent turbidity.
Leopold filters are designed according to loading rate, run time, and head loss. Properly designed to upstream and downstream processes and filtrate quality requirements, Leopold filters can help you meet the new water quality regulations.
