– Others

The second NTU Terminator filtration test, held at the end of 2020, was carried out at a cooling tower system at our customer’s facility, one of the leading companies in the polyester industry. Filtration tests were performed under a pressure of 2.6 bar at a flow rate of 3 m³ / h, using serially connected Filternox^® NTU Terminator filters.

3. Conclusion and Evaluation

In the filtration tests performed with the filtration of Filternox^® NTU Terminator filters;

Cooling tower X:

• An average of 40% suspended solids removal was achieved in one stage and 58% in two stages.
• Turbidity removal was achieved on average 48% in one stage and 65% in two stages.

Circulation of cooling tower X water, taken into 500L IBC tank:

• As a result of 1 hour of circulation of the water with an initial TSS value of 134 ppm and initial turbidity value of 49 NTU, it was observed that the TSS decreased to 17 ppm and turbidity dropped to 7.22 NTU.

As a result of the filtration to be performed in the cooling line with Filternox^® NTU Terminator filtration system;

• Lifetime of the tower filling will increase
• The amount of chemicals used in the system will be reduced
• The amount of tower blowdown water will be reduced
• Cooling efficiency will be increased
• Unnecessary stops / work interruptions will be prevented
• Operation, maintenance and energy costs will be reduced
• The cooling line will be protected from particles

Cooling efficiency will increase substantially as a result of all the above mentioned benefits.

Filternox^® engineering and test team conducted filtration tests at a local food company’s refinery clean tower point in October 2020. Tests were carried out with serially connected Filternox^® NTU Terminator filters at flow rates of 2, 3 and 5 m³/h  and under 2, 2.6 and 2.7 bar pressure.

Conclusion and Evaluation

In the filtration tests performed with the filtration of Filternox^® NTU Terminator filters;

At Refinery Clean Tower Point:

• TSS removal was achieved on average of 47% in one stage and 67% in two stages.
• Turbidity removal was achieved on average 56% in one stage and 73% in two stages.

As a result of the filtration to be performed in the cooling line with Filternox^® NTU Terminator filtration system;

• Lifetime of the tower filling will increase
• The amount of chemicals used in the system will be reduced
• The amount of tower blowdown water will be reduced
• Cooling efficiency will be increased
• Unnecessary stops / work interruptions will be prevented
• Operation, maintenance and energy costs will be reduced
• The cooling line will be protected from particles

With all of these mentioned benefits, cooling efficiency is increased incredibly.

Machinery Cooling Water Filtration System Commissioned

Total of 8 filters have been commissioned last week at our customer’s facility. This is one of the most important producers in the Turkish iron & steel industry.

If you need to improve the outlet quality of your treatment plant, Filternox^® can help you with the NTU Terminator deep filtration solution.

More specifically, Filternox^® NTU Terminator can help improving the water quality at long-lasting wastewater treatment plants that have become overloaded or undersized because of population growth and old technology aeration solutions.

Please contact us for testing, renting and sales options.

Sea water deep filtration with Filternox NTU Terminator to improve the inlet quality of UF & RO

We have performed another test with Filternox^® NTU Terminator at a customer’s facilities, for one week. They extract seawater where occasionally there is heavy traffic of ships. The test was however carried out during a period with low ship traffic.

Filter 1 with 5 micron filtration level and Filter 2 with 2 micron filtration level were placed before UF and RO to improve working conditions and extend the life of UF and RO systems plus minimising the use of chemicals.

As a result of the filtration tests performed, it was observed that inlet and outlet waters appeared relatively clean. The filters performed very efficient deep filtration and the drainage waters from both were significantly dirty, with a high level of turbidity.

At the outlet of the sea water treatment, turbidity removing efficiency Filternox filters was 41% at the first stage and 68% at the second stage, on average. On the other hand, TSS removing efficiency in a single stage was over 70%.

Using Filternox^® NTU Terminator filtration system as pre-filtration before a UF system, we can conclude:

• The system can filter out peak or high dirt loads that may occur, especially during periods of heavy sea traffic, before they reach UF and RO systems and keep them protected.
• Performance of UF systems and service lifespan of UF membranes will increase.
• Thanks to the increase in UF system performance, the dirt load on the RO membranes will decrease and the service life of the RO membranes will also increase.
• There will be no need to use the cartridge filters after the UF system, before the RO system; or if used, the cartridge life will be much longer.
• Reduction in the amount of chemicals used in the system.
• Decrease in maintenance time and expenses.
• Decrease in the amount of wastewater discharged for the backwashing of UF and RO systems.

Keep your UF and RO systems safe and healthy. Save water and our world!

Another filtration test has been performed with process well-water at a food company.

After 1 hour of filtration, it was observed that the drainage sample was dark in color and contained a large amount of particles.

Filternox® NTU Terminator is capable of trapping extremely small particles, even smaller than 1 micron.

At the end of this filtration test, Filternox® NTU Terminator decreased the TSS level from 20 ppm to 8 ppm and turbidity from 25 NTU to 3.29 NTU.
