JVK FILTER ELEMENTS

APPLICATION OF MEMBRANE PLATES

JVK filter elements and especially JVK Membrane Plates

have been established in many industrial filtration
applications since 1962.

WASTE WATER / SEWAGE TREATMENTPLANTS

Waste water treatment and
water purification for potable water
dewatering and decontamination of industrial and
municipal waste water:
waste liquors from dust scrubbers,
paper, leather and latex waste water,
waste cuttings of wood and stone,
coal and ore suspensions from flotation processes
neutralization plants, oil refineries
metal hydroxide sludges (galvanic)
drilling mud of oil rigs

JVK has contributed significantly to many developments in the

field of solid-liquid separation with new ideas and designs.
JVK is producing one piece moulded plates for filtration equipment
in accordance with DIN standards or as special designs in
polypropylene or other thermoplastic materials with the most
modern ICM technology.
JVK offers long-term experience on development, production
and application of membrane plates. In 1964 already, the first
trials had been completed in a chemical plant with membrane
plates.
JVK commenced the dedicated production of membrane plates
equipped with elastomeric membranes in 1968.
JVK membrane plates are successfully used worldwide due to
the design, the high quality standard and the continuous
product development.

CHEMICALS
Manufacturing of mineral pigments,
titanium dioxide and organic dyestuffs,
filtration of phosphoric compounds and ferments for
the production of wetting, washing and cleansing agents,
chemical intermediate products and fillers e.g.
kaolin, aluminum oxide, activated clay etc.
chlorine electrolysis, filtration of brine to produce
chlorine, sodium hydroxide, zeolite, silica etc.

TECHNICAL ADVANTAGES OF MEMBRANE PLATES

residual moisture

uniform and adjustable capillary structure

optimal cake washing effiency during the shortened washing time
reduced washing liquor consumption
4. EXCHANGEABLE MEMBRANE
The Membrane is easily exchangeable
not necessary to exchange the complete filter plate
only replacement of membrane necessary
Membrane materials can be adapted to suit operating
conditions

savings

Residual moisture after the filtration with membrane plates

A = End of Filtration with membrane plates
B = End of Filtration with chamber plates
C = Residual cake moisture after the squeezing with membrane plate
A`and C` are possible product dependent operating values.
The optimal operating condition A can be determined after a few filtration
cycles. Cake compressibility, filter cloth, pump capacity etc. will influence the
processoptimisation.

1. SHORT FILTRATION CYCLE

A low cake moisture content by pressure filtration can only be
achieved with resseced plates by high filtration pressure
and long filtration time (B).
The membrane system requires much lower filtration pressure
to fill the chambers (A)
The low cake moisture content is caused by squeezing with a
flexible membrane ( C).
The production cycle is determined by
fast feed of chambers at low filtration pressure
cake squeezing in a few minutes with pressures up to 5 N/mm2

2. LOW RESIDUAL MOISTURE

application of squeezing pressure to filter cake by elastic
membranes replaces the high pressure filtration phase of
conventional recessed plates.
remarkable reduction of residual cake moisture in shorter time
reduction of total filtration cycle time
increased filtrate output
very short discharge time
increase in solid content up to ca. 100 %
with special vacuum process
less cake adhesion on the filter cloth
automatisation of filtration process
lower costs for pumps
savings in energy
less transport and dumping costs due to compact and very
dry filter cakes

3. SHORT WASHING CYCLE

JVK membrane technology creates homogeneous cake without
cracks by applying a low membrane squeeze pressure during
cake washing

5. WELDED MEMBRANES
For special applications membrane may also be supplied totally
sealed and welded into the plate
6. LOAD ON MEMBRANE
No direct press closing force is applied to the membrane surface:
The membrane does not cover the sealing rim of the plate and
the support bosses of the plate in case of the exchangeable
membranes
no need for an additional filter press closing force control
in most applications
7. HIGH ELASTICITY OF MEMBRANE
The elastic membrane adjusts itself to the shape of the cake without
permanent deformation caused by uneven cake surface or different
cake densities:
homogeneous cakes of equal density
for effective washing and cake airdrying
extension of the membrane into empty
chamber without any problems
8. SEALING OF FILTER PLATE SYSTEM
The plan-parallel machining of membrane plates according to DIN
7129 achieves a perfect sealing surface. For applications where a
liquid-tight seal is required, a complete gasketed plate (CGR) is also
available.
9. INCREASED FILTRATE OUTLET CROSS SECTIONAL AREA
The diameter and quantity of filtrate outlet ports can be adapted to
process requirements
large filtrate volumes can easily be drained off
no blockages, often due to solids and/or cristallisation
no restrictions at clogging outlets due to filter cloth obstruction
10. FIELDS OF APPLICATION
The materials used by JVK, allow installations in almost every field of
application and can be adapted to any working conditions:
temperatures 20 up to 140 C
filtration pressure up to 1,5 MPa (15 bar)
squeezing pressure up to 6,0 MPa (60bar)
adaption to resist chemical conditions
11. SAFETY OF EXCHANGEABLE MEMBRANE SYSTEM
The exchangeable JVK membrane is not bolted or welded as a rigid
connection into the sealing area.
the pressure of the squeezing fluid can only be maintained
under full closing pressure of the filter press
the membrane is immediately released from groove, if the
closing pressure is lower than the squeezing pressure
pressure release without destroying the membrane
reduction of safety feature requirements

OPERATION OF THE MEMBRANE PLATES
1. FEEDING OF FILTER PRESS
During the feed step (1) the elastic membrane (2) moves back
towards the core plate (3) under low tension.
Press feeding finishes when the optimal operating point is
achieved.
Filtration finishes prematurely at a lower pressure and less time
compared to chamber plates.

4. SQEEZING OF FILTER CAKE

According to the cake structure the membrane pressure can
reduce the residual moisture content in the filter cake significantly.
The squeezing pressure is normally higher than the filtration or
the pre-squeezing pressure.
After squeezing the cake thickness should be smaller than the
chamber depth. Otherwise overfilling of the chambers could
have occurred or the cake is incompressible.

2. WASHING THROUGH FEEED PORT

(GAP-WASHING)
After finishing the filtration the cakes may be washed through the feed
port. For efficient washing no squeezing pressure and no chamber
overfilling allowed (4) .
Cake washing fluid is forced through the pasty cake center and
exits on both sides of the cake.

5. FILTER CAKE BLOWING

Filter cake blow is performed using the corner ports.
Non compressible filter cakes can be dried further with the
assistance of squeezing pressure.

3. PRE-SQEEZING AND
WASHING THROUGH CORNER PORTS
The filtercake is consolidated in the chamber
by applying low membrane pressure to avoid
gaps or cracks.
Following washing versions can be used:
washing in one direction right to left
washing in diagonal directions
washing top to bottom or
bottom to top (flooded)
washing fluid is forced to penetrate the cake
from the membrane chamber plate
to the combination chamber plate.
