Water filtration is more than the sum of its parts.

And no one knows more about filtration than Leopold^®, the leader in gravity media filtration. Whatever your application:

• Potable drinking water treatment
• Tertiary wastewater treatment
• Nitrate removal in water or wastewater
• Pretreatment prior to low pressure membrane systems
• RO membrane desalination pretreatment

Leopold^® engineers can assist you in developing a cost effective, efficient, high performance Leopold^® Filterworx™ system designed to meet your requirements.

Everything worx better when it all worx together.

Backwash and System Controls: The Keys to Efficient Operation

Longest filtration run cycles lower operating costs: FilterWorx^® control system continuously monitors filtrate quality and filter bed conditions. Your filter is backwashed only when needed and only for as long as needed. Filtrate quality aand filter run volumes are optimized, while reducing energy consumption and wastewater generation. Our controls keep the filter media well conditioned, extending the life of your filter.

Efficient deep cleaning backwash: Genuine Leopold^® Underdrains and I.M.S^® media support evenly distribute backwash water and air to every portion of the filter bed, eliminating dead zones. Air scour increases shear and develops collapse pulse throughout the bed, for a deep clean with reduced backwash water consumption.

Complete integration: We use standard communication protocols that easily integrate into most other plant control or SCADA systems.

We build efficiency and innovation into every Leopold^® Filterworx™ Filtration System

Leopold^® engineers have been at the forefront of gravity media filtration since 1924. With more experience than anyone in the industry, we can help you analyze, evaluate and design all aspects of your complete filtration system.

• Evaluate influent water qualities, including seasonal changes, demand requirements, and determine the best pretreatment options.
• Determine optimal loading rates and best design configuration to meet site conditions and operational requirements.
• Select the best media characteristics, media quality, bed composition, bed depth and grain size distribution to match the filter configuration, influent quality, pretreatment processes and required filtrate effluent quality.
• Design the backwash process to restore original headloss and solids storage capacity, maximize filter runs while minimizing power costs and wastewater generation.

Each component is designed to achieve the longest possible filtration cycles to meet your permit requirements at the lowest possible costs.

Support every step of the way

Our commitment to your satisfaction goes beyond designing the best system for your application and providing single source supply of all components.

• Pilot testing: We will test your filter at our site or yours. We can run a pilot test of your system at your site, to demonstrate performance. Or we can test a full-scale lateral run with your flume configuration at our Product Development Center. There you can witness first hand the head loss and flow distribution during backwash.
• Construction and start-up assistance: Our experienced technicians are available to supervise the correct installation of your filter, to insure proper operation. We can also provide ongoing support through calibration, commissioning and start-up. Throughout the life of your filter, we can assist with ongoing process evaluation and troubleshooting, to keep your filter operating at peak efficiency.
• Rehabilitation services: We can analyze your existing filter performance and provide a cost effective rehabilitation to upgrade your system to current standards. From underdrains to trough configuration, media selection, and controls, we can custom design your system to provide optimum performance.
