Corrosive-Resistant Process Filters
Mott offers four types of HyPulse® liquid-solid process filters for high temperature and corrosive environments.
LSI filters incorporate proprietary inside-out filtration technology. After each cycle, solids are backwashed off the inside of the elements and discharged as a concentrated slurry or wet cake. LSX filters provide uninterrupted filter cycle performance through cross-flow filtration. Slurries flow through the filter elements, allowing filtrate to exit the system on a continuous basis while particulates remain in the recirculating stream. LSP filters offer conventional outside-in filtration for polishing streams with solids concentrations of less than 100 ppm. LSM filters place inside-out filtration within a double open-ended design which is ideal for high-density solids or solids concentration.

| Cleaning |
Mott LSI filters for chemical processes are designed for clean-in-place performance, meaning filter elements can discharge cake build-up without having to open the filter for maintenance. Once a terminal pressure drop has been reached, the cleaning cycle automatically initiates to discharge cake build-up through gas assisted pulse or through a backwash cycle. Particles will embed in the filter media over time, requiring the elements to be cleaned by a third-party company. Various cleaning techniques can be used to prolong life of the elements. For a recommendation of a cleaning company, please contact a Mott representative. It is recommended you keep a spare set of filter elements to continue operations while elements are being cleaned. |
The Mott Filter Design Process
- Filter Feasibility Testing – In our Customer Innovation Center, we will replicate, or very closely correlate, your process conditions to determine the appropriate media grade and material for your application. We will provide you with a comprehensive, in-depth analysis to prove the feasibility of using porous metal in your process and furnish you with a comprehensive ROI justification.
- Pilot Testing – As an option, we can install a pilot unit in your facility enabling you to witness, first-hand, how our filters will perform in your process stream and under your actual operating temperatures and pressure conditions.
- Front-End Engineering Design – Our Front-End Engineering Design (FEED) process provides you with a complete process engineering package, including vessel drawings, a preliminary equipment layout drawing, piping and instrumentation diagram, process flow diagram, valve and instrument list, and a detailed process functional description.
- Fabrication – When it comes to fabricating your system, we can handle as much or as little as you need – from fabricating only the filter vessel, to providing a complete turnkey skid system.
- Operational Support – When your filtration system is complete, our professionals can provide equipment commissioning and startup services, training, ongoing technical support and quality assurance testing for the life of your system.
Depending on your needs, Mott can provide just the filter elements, a vessel and elements, or provide you a full turnkey system with the vessel, frame, piping, instruments, and controls
