▍INOCO-XF-F SERIES
BACKWASHING FILTER SERIES
Excellent Performance and
Extremely Low Energy Consumption
The INOCO-XF-F series full-automatic backwashing filter is a kind of
industrial automatic filters for multiple comprehensive purposes, which can
ensure that the filtered liquid is pure and reliable.
The INOCO-XF-F series are suitable for most of the water filtration standard
applications in terms of handling capacity, precision and reliability, and it
maintains a good operating condition even under harsh operating conditions.
The pressure design of filter body is usually based on the standard design of
ASME U stamped and steel pressure vessels. The filter can also be meet the
specific requirements of other design standards.The main part of the equipment
is made of carbon steel, carbon steel lined with rubber, stainless steel,
dual-phase steel and other materials. At the same time, we can also provide
you with main part made of special materials like titanium and pure nickel.
Core Principle
Multiple Filter Elements in A Single Casing
Several separate filter elements are equipped in the filter. Compared with
other single filter-element products of INOCO, with the same chamber diameter,
the filtering area of XF-F series filter increases by multiple times.
Each filter chamber is equipped with an independent filter element assembly
that provides a large filtration surface area and free permeation cross
section and maintains the differential pressure at a very low level.
Since the diameter of filter element is generally no more than 80mm, the
filter element can withstand a high operating differential pressure. When
cleaning, the cleaning components backwashing each group of filter elements
one by one, so that the filtration quality and safety of the filtering process
are fully guaranteed.
Cleaning Principle
Clean Water Backwashing after Filtering
Cleaning process: the single filter unit carries out filtering and
backwashing one by one. Therefore, the filter will not reach a critical level
of contamination. The backwashing operation can be triggered by differential
pressure and/or time. The cleaning (backwashing) process is extremely fast and
thorough; since there is always a set of filter elements in standby mode, the
system pressure remains almost unchanged from beginning to end, and the filter
consumes a very small amount of backwashing detergent.

Filtration
In the process of filtering, the water to be filtered passes through the
inlet flange and flows into the filter chamber from below into the filter
elements, which contains organic and inorganic ions will be captured by the
filter elements, and the filtered water will reach the filter outlet through
the filter screen.
Backwashing
The backwashing stage is initiated by differential pressure and/or timer.
During the backwashing process, the filter elements with bottom opening are
alternately flushed in sequence without interrupting the filtering process. To
achieve an alternate flushing, the gear motor drives the flushing arm to
rotate, passing through each of the filter element openings. At the same time,
the flush valve opens. The pressure drop created inside the filter element
(system pressure versus atmospheric pressure) causes the water flowing through
the filter element to flow in the opposite direction, flushing the organic and
inorganic particles trapped in the filter element out of the filter element.

▍INOCO-XF-FV SERIES TAPERED OPTIMIZATION TECHNIQUE
Special solutions required for extremely demanding conditions, Such as
filtering heavily polluted sewage.
INOCO XF-FV series filter elements ingeniously use traditional wedge-shaped
steel wire filter elements to design innovative conical filter elements. The
element material we use stainless steel,dual-phase steel or alloy steel. The
wedge-shaped gap filter element can effectively filter the fluid with less
adhesive and is also suitable for the coarse-filtering field.
The size of wedge-shaped clearance filter element is related to the required
filtration precision, and the V-shape can be designed to be in the direction
of water flow or be opposite to water flow direction. Select different designs
according to different working conditions.
The wedge-shaped steel wire filter element has a bore diameter spanning from
25µm to 1000µm, and has a long service life; some components can be used in
the filter for more than 20 years.
▍INOCO-XF-F SERIES STANDARD FILTER ELEMENT
The INOCO-XF-F series adopts the multi-filter column mode that has a larger
filtering area and is easier to clean compared with other INOCO scraper or
brush structures. The filter element is made of stainless steel, dual-phase
steel or alloy steel. The wedge-shaped gap filter element can effectively
filter the fluid with less adhesive and is also suitable for the
coarse-filtering field.
The advanced mesh shape helps block media that can cause blockage, while the
wedge-shaped filter element is especially suitable for filtration with high
differential pressure.
The size of wedge-shaped clearance filter element is related to the required
filtration precision, and the V-shape can be designed to be in the direction
of water flow or be opposite to water flow direction.
The wedge-shaped steel wire filter element has a bore diameter spanning from
25µm to 1000µm, and has a long service life; some components can be used in
the filter for more than 20 years.
▍INOCO-XF-FS HIGH-PERFORMANCE VERSION
DUAL SUCTION-HIGH-PERFORMANCE VERSION BACKWASHING FILTER
Specially developed for backwashing filters for water treatment under highly
demanding conditions, such as heavily polluted water resources
Typical applied in grey water after flue gas desulfurization, ballast water
Ultra large flow filtration (above 3000M3/h), high precision filtration (5~25
micron)
In order to make the INOCO-XF-FS series backwashing filters achieve optimal
filtration performance under conditions of severe pollution (especially
pollution difficult to eliminate under low working pressure), the dual
backwashing function is adopted by us to enhance the dual filtering principle
(in which, the transverse flow and adverse flow dual-way backwashing is
produced) that is technically mature. The rotating flushing arm is located on
the upper and lower sides of the filter element assembly, and the filter
element is alternately flushed from the upper and lower directions by the
filtering medium (i.e., nonsynchronous flushing), and the process will not be
interrupted at all times. In addition, the newly developed hydrodynamic
components increase the backwashing speed in each filter element column, and
with the dual backwashing system, a thorough flushing of the entire filtration
area is ensured.
The openings at both ends of the filter element allow the water to be
filtered to flow in simultaneously from both ends. Due to its length and the
increased diameter, its filtering area is particularly large. The hydrodynamic
components located in the middle of the filter element also increase the
backwashing speed, thus maximizing the backwashing effect. This maximum
backwashing effect, provided by hydrodynamic components and alternative
flushing function, ensures failure-free operation and greatly reduces the risk
of filter blockage.
Filtering
During the filtering process, the water to be filtered passes through the
inlet flange and enters the filtration chamber. A portion of unfiltered water
flows through the standpipe in the middle of the filter element into the upper
part of the filter and finally flows into the filter element from above. This
means that the water flows into the filter element from both above and below,
and the organic and inorganic particles contained therein are trapped by the
filter element. The filtered water passes through the filter screen to the
filter outlet.
Backwashing
The backwashing stage is initiated by differential pressure and/or timer.
During the backwashing process, the filter elements with openings at both ends
are alternately flushed up and down in sequence without interrupting the
filtering process. To achieve the alternate flushing, the gear motor drives
the flushing arm to rotate, passing through each of the filter element
openings. At the same time, the flush valve opens. The pressure drop created
inside the filter element (system pressure versus atmospheric pressure) causes
the water flowing through the filter element to flow in the opposite
direction, flushing the organic and inorganic particles trapped in the filter
element out of the filter element.The hydrodynamic element located at the
center of the filter element now increases the backwashing speed and evenly
distributes the backwashing force on the filter element.
