Inherently
more efficient than
traditional outside-in liquid solids
filters, Mott HyPulse LSI filters pass
the slurry through the elements from
the bottom-up and inside-out, resulting
in less heel, minimal loss of filtrate,
and easier discharge of solids.
|
Four
ways to separate solids from liquids.
HyPulse®
LSI filters incorporate inside-out filtration, a method
and design unique to Mott Corporation. At the end of each
filter cycle, solids are backwashed off the inside of the
elements and discharged as a concentrated slurry or wet cake.
Distinct
LSI benefits include:
- Eliminates
cake bridging and associated problems
- Higher
surface area to volume ratio
- Allows
for cake washing
- Minimizes
heel
- High
solids discharge capability
- Ideal
for recovery of carbon-based precious metal catalysts, activated
carbon, organic salts, FCC catalyst from slurry oil, and
pre-coat filtration applications
- Rapid
turnaround between cycles keeps filter on-line
- Offers
ultimate particle retention, backwashability, solids capacity
and strength
- Can
be used in conjunction with filter aids for difficult filtration
applications
Other
unique Mott alternatives, HyPulse®
LSM filters place inside-out filtration within a double
open-ended design. High-density solids are allowed to settle
directly into the discharge hopper. LSM filters may be operated
on a filter/backwash cycle schedule, or can be used as concentrators
in a recirculating system.
-
Feed
can be introduced at top of the filter
-
Allows
longer cycles
-
Keeps
high-density solids from clogging elements
-
Achieves
higher solids concentration
-
Can
be used as a cross-flow concentrator or a continuous-loop
reactor filter
-
Incorporates
efficiencies of inside-out filtration
-
Ideal
for Raney nickel catalyst recovery, and for steady-state
continuous operation in critical process applications

HyPulse
LSP filters offer conventional outside-in filtration
for polishing low solid streams with flows under 100 ppm.
Easy to use and maintain, LSP filters provide reliable,
permanent filtration that outperforms other types of media
in a number of ways:
-
Helps
reduce operator exposure to hazardous materials
-
Easy
access to elements from top
-
Element
bundle is removable as an assembly
-
Filter
areas up to 2200 ft2, withstands differential pressure
up to 500 psi
-
Ideal
for polishing filter applications, inorganic bromide salts,
copper chromite catalyst recovery, and ion exchange filtration
applications
HyPulse
LSX Process filters provide uninterrupted filter cycle
performance through cross-flow filtration. Slurries flow
through the open-ended filter elements, allowing filtrate
to exit the system on a continuous basis while particulates
remain in the recirculating stream. This is the ideal filtration
method for slurries with unique particulate characteristics,
or for achieving maximum retention of valuable particulates
such as expensive catalysts.
-
High
solids concentration factor
-
High
cross-flow velocities (5-10 ft/s) keeps solids in suspension
-
Filters
out finer particulates
- Ideal
for operation with continuous loop reactors, concentration
of radwaste, and very fine particle separation
-
Applicable
for batch concentrations or continuous-stage operation

The
tangential flow in Mott HyPulse LSX filters make them
especially well-suited to filtering out fine particultes,
which tend to be held in suspension. LSX elements can
be easily cleaned by backpulsing the filter while it
remains on-line.
