High-strength, high-performance filtration of liquids and gases.

What makes Mott Corporation the company of choice for process filtration.

When it comes to developing efficient, long-lasting process filtration systems, no other company has more experience, and as much to offer, as Mott Corporation. For decades, users of bag, plate-and-frame, and leaf filters have switched over to Mott for the distinct advantages that Mott systems provide.

Giving you more than you need, but not more than you want – the optimal balance.

At Mott, we never rely on “just enough” engineering. Products are routinely designed and tested to perform at the specified flows and differential pressures in pilot tests on-site or in our applications laboratory. Which is why you’ll find optimal surface area in Mott filter elements. Mott provides complete filter systems modularized to include all valves, instruments, controls, piping and gauges.

Uniform, high-precision porosity –
Pore size and pore distribution are controlled to create filtration media with distinct porosity characteristics.

High-strength media –
Sintering holds filter media together at the molecular level, eliminating the tear, fatigue and breakthrough problems typical of other media.

Reduced spare parts expense –
Porous metal filter elements seldom need replacing, unlike disposable non-metal cartridges and bags.

Ease of cleaning –
Mott filters are easily freed of particulates by using blowback (gas) or backwash (liquid) cleaning methods – without scraping, scrubbing, or rotating filter elements. Contaminants may also be removed with water, steam, air, solvents, caustic or acid washing, or with ultrasonic cleaning.

Totally enclosed – Backwashing filter elements reduce operator exposure to hazardous chemicals.

Waste minimization – Cleanable filter media eliminates incineration or landfill costs associated with disposable filters.

Minimal maintenance –
Mott filters have no moving parts, resulting in simpler and less frequent maintenance procedures.

Single-stage filtration –
An entire train of process filtration steps may often be replaced with a single Mott filter system.

Wide selection of media –
Mott offers the widest selection of filter media, more than 20 in all, ranging from standard 316L stainless steel to corrosive-resistant nickel and Hastelloy^®.

Skid-mounted Mott hyPulse LSM system used for catalyst recovery.

High-quality filtrate, maintenance-free operation.

A major United States gulf coast chemical producer required continuous, clear filtrate in conjunction with the removal of Raney nickel catalyst from a butanol solvent. The Mott HyPulse LSM design was chosen for its ability to remove catalyst particulate efficiently. And, because the open-ended LSM allows concentration of solids in a hopper, the particle loading on the filter elements is significantly reduced, resulting in longer cycles.

This particular LSM was fully automated and skid mounted, and has provided clear filtrate quality along with maintenance-free operation. In addition, the Mott LSM’s multiple operation modes afford flexibility in how particulate is removed.

Multiple Mott hyPulse LSX crossflow systems can be arranged to optimize uptime and facilitate maintenance.

Recovering precious-metal catalyst safely, easily, without interruption.

One of Europe’s leading chemical manufacturers required the removal of platinum-on-carbon catalyst from a continuous catalytic oxidation reaction. The high cost of the precious-metal catalyst made high-efficiency capture essential. And to enhance productivity further, cleaning operations had to be performed without interruption of process workflow.

Mott provided a total of 6 Mott HyPulse LSX crossflow modules arranged in three parallel trains. Each module was engineered to perform individual backpulse cleaning, enabling the system as a whole to deliver uninterrupted filtration – thereby eliminating the operator exposure and costly downtime caused by having to replace disposable filter elements.
