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!

Is your well water this clean?

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.

Steel industry filtration test report

Last week we carried out some testing at our customer’s facilities. They are one of Turkey’s leading iron and steel factories. Our customer was quite pleased with the results.​

Filtration test was carried out with Filternox® NTU Terminator filtration system.

Using water taken from the cooling water delivery line, the Filternox® filtration system achieved a very high efficiency by removing 64.3% of TSS and reducing turbidity by 75.2% on average.

As a result of this test, we conclude that all the water can be cleaned to an exceptionally low degree of pollution in a very short period of time by using the Filternox® NTU Terminator filters. We recommend our customers to use them to minimize blockages in the system, save make-up water and reduce unnecessary maintenance work and energy losses.

 

Chiller cooling water filtration

NTU Terminator model has just been engaged with Chiller Cooling Water Filtration.

According to the analysis results,

  • TSS for drainage water is 91 mg/l, although inlet and outlet water is under range.
  • Turbidity for drainage water is 70 ntu within 90 minutes, whilst the turbidity for inlet water is 1.51 ntu.

Three days after the system was commissioned, the customer wanted to keep the pollutants accumulated in the line by chemical cleaning and remove them from the system. For this reason, a filter bag was placed in the filter drainage outlet at the same time with the chemical cleaning. Within about 3 hours, as can be seen clearly in the pictures, the high amount of pollutants were removed from the drainage through the automatic backwashing of the filter and they were kept in the bag filter. During this cleaning, the pollution was removed from the system with the successive backwashing of the filter and the customer’s system has become fully functional as it should be.

Well water filtration requires technical quality and capability

In general, prominent problems in well water filtration are grouped under three main headings:

  1. With the first start of the pump, heavy pollution comes in and sudden blockage occurs in the filter.
  2. Turbidity in the water.
  3. Iron and manganese in the water.

The solution to the first of these problems is challenging as it requires a special filter with backwash system. Usually a tank is installed after the well. This increases investment cost and adds the need to be cleaned periodically.

Filternox®, has developed solutions to these three problems mentioned above without the need for adding a balance tank.

With the first activation of the pump, all the sand, silt and other organic or inorganic particles accumulated in the well can suddenly enter the filter, cover the surface of the filter screen and block it. In this case, Filternox® patented double cleaning filter is the definite solution. The double cleaning filter discharges first all the coarse and cleanable particles, swept with a brush, via its drainage line. Immediately after this process, the remaining particles left on the screen surface are removed by the vacuum suction system.

 

 

If there is turbidity in the water and this is a problem, then Filternox® NTU Terminator takes over the solution. NTU Terminator incorporates a deep filtration screen specially developed by Filternox R&D division and significantly eliminates turbidity thanks to the adsorption property of this screen.

Thirdly, if there is iron and manganese in the water, since they are dissolved, first, chlorine is added to oxidize these metals to form rust particles. Filternox® NTU Terminator retains these particles within its special screen.

Finally the hardest issue: what should be done if the first and second problems coexist?

Our patented double backwash system Filternox® filter can also be manufactured as NTU Terminator as a special design, to suit the specific needs of your facility or industry.  This way, very poor-quality water coming from the well is rid from particles and turbidity.
