Product Description
UFNorit® Performance parameters
The operation mode of Norit series ultrafiltration technology adopts the full flow filtration. Therefore, it saves the
operation energy greatly, and the typical filtration pressure difference is 0.3-0.8bar (5-12PSI). The solid
particles deposited on the membrane surface are removed by regular backwashing, without any addition of any
chemical cleaning agent. The solid dirt is removed by regular backwashing, thus avoiding the deposition on the
membrane surface. Such operation mode is prior to the immersed membrane filtration. The immersed
membrane filtration adopts the external pressure filtration because of immersing the membrane in the water
tank, so it will lead to the accumulation of solid contaminants in the water tank. And once any membrane silk is
broken, it will lead to the leakage of contaminants into the effluent water. The dirt which is absorbed on the
membrane surface and can't be removed through backwashing shall be removed by online chemical enhanced
backwashing (CEB). At this time, the membrane components will not be removed but cleaned online. A small
amount of chemical cleaning agent shall be added in the process of chemical enhanced backwashing. After the
short-time immersion (generally 5-10 minutes), the chemical cleaning agent will be discharged, and the
ultrafiltration membrane is re-cleaned. Generally, it is not necessary to remove the Norit ultrafiltration
membrane before cleaning, which avoids the possible cross contamination caused by the repeated use of
cleaning agent. In addition, the artificial monitoring is not required in the equipment operation process.
◆Process parameters Such membrane component is used for the full flow filtration. The typical process
parameters are as follows:
• Operating pressure: 0.1~0.2MPa
• Operating pressure difference: 0.01~0.1MPa
• Backwashing pressure: <0.3MPa
• Filtered water flux: 60~135 L/m2.h
• Filtration cycle: 15-60 minutes (depend on the quality of raw water)
• Backwashing flux: 250~300 L/m2.h
• Backwash time: 30-60 seconds (depending on the quality of raw water)
• CEB spacing: 12h-48h (depend on the quality of raw water)
• CEB dosing kinds and concentration:
The hole diameter of Norit ultrafiltration membrane is 10nm, and the distribution of hole diameter is very concentrated. These characteristics guarantee that the ultrafiltration membrane becomes the absolute barrier
of all suspended solids, including bacteria, colloform, etc. Regardless of the influent water conditions, the
high-quality water supply can be kept continuously. The effluent water indicators are as follows:
• Suspended solid<0.5mg/L
• Turbidity <0.1NTU
• Bacteria removal rate >6log
• Virus removal rate >4log
Advantages of UFNorit ® construction
Since UFNorit ultrafiltration membrane is designed into the form of "similar reverse osmosis", it is very easy for
those design and construction teams having the reverse osmosis experience to accept such design. Thus,
there will be more choices of determining the place and personnel who carry out the specific construction and
building.
Low construction site requirements
The ultrafiltration system can be installed in any flat ground with enough bearing capacity. It doesn't require any
field device, such as water tank for placing the membrane.
The operation is convenient.
The ultrafiltration membrane system realizes the completely automatic operation: The filtration, backwashing
and chemical enhanced backwashing are monitored by the control system. It is not necessary to remove it
before cleaning. Therefore, the operating expense only include the expense for chemical cleaning agent and
energy consumption of system operation. High flux/low pressure, energy saving - Norit ultrafiltration membrane
can keep higher flux during operation. According to the different purposes, the flux can be 60 -135L/m 2 h. The
high performance of Norit XIGA ultrafiltration membrane guarantees the very low operating pressure of
ultrafiltration system, generally 0.3-0.8bar. Thus, the system only requires the very low operation energy
consumption, generally 0.1-0.2kWh/m 3.
Under the condition of same effluent water capacity, the required membrane area is small.
Since the ultrafiltration system operation is carried out under the condition with high membrane flux, the
required membrane area is smaller under the condition of same effluent water capacity. Thus, the membrane
maintenance and replacement will decrease.
The membrane cleaning expense is low.
Norit membrane technology generally uses the common chemicals to clean the membrane. In addition, only the
membrane cavity and connecting pipeline are soaked in the chemical cleaning agent during cleaning, thus
greatly reducing the usage amount of chemical cleaning agent. Differing from it, the immersed membrane
technology needs to make the whole water tank be filled with the cleaning agent.
High resistance to chemical corrosion
Norit ultrafiltration membrane can be operated and cleaned under the widespread chemical environment.
During cleaning, pH value is 1-13. With the high resistance to oxidation, Norit ultrafiltration membrane can be
used to treat water after chlorination and can be cleaned by the sodium hypochlorite, hydrogen peroxide and
other strong oxidants.
The intelligent system guarantees the convenient and stable operation.
Norit uses the intelligent system to control the ultrafiltration process. The intelligent control system (CIS) can
monitor the quality of influent water and transmit it to the central control system, thus adjusting the operating
parameters. Under the condition with lower influent water turbidity, the backwashing frequency shall be
adjusted properly.
UFNorit® X-225 Vertical membrane
◆ Full flow/cross flow operation
◆ Built-in component shell
◆ Norit series ultrafiltration membrane: The unique FSFC flow distributor in 0.8 mm and 1.5 mm components
ensures that.
◆ The liquid takes effect on the whole length of the membrane component and pressure container, ensuring
the even flow distribution.
◆ The penetrating fluid is discharged smoothly.
◆ The backwashing and chemical washing are very effective.
◆ The full flow/cross flow filtration operation is carried out under the low trans-membrane pressure and low
energy consumption.
UFNorit® X-225 low turbidity
◆UFNorit® X-225 low turbidity design is especially suitable for the water treatment process with the solid
suspension content in the feed liquid reaching 200mg/L. Such design adopts CAPFIL component with the
membrane inner diameter of 0.8 mm and 1.5 mm.
