Kurita NT Technology – innovative biofouling control.

Biofouling is a major problem for the efficient operation of an open cooling water system. Slime produced by bacteria can very quickly form a strong stable biofilm on heat exchanger, pipework and tower fill surfaces with undesired consequences:

  • Fast development - can be within days
  • Decrease heat transfer - 1µm of biofilm = 5 – 10 % less heat transfer
  • Decreased Flows – increased pumping cost and lost production
  • Blocked Tower Fill – reduced cooling efficiency
  • Increased risk of high Legionella counts
  • Increased risk of under deposit corrosion

Traditionally to control biofouling and biofilms, combinations of biocides and bio-dispersants are used at high cost and risk of increased corrosion
Kurita now offers an innovative alternative – Kurita NT Technology.

What is Kurita NT Technology?

Kurita NT Technology is a stabilised inorganic chlorine compound with many unique benefits.

  • Low dosage efficiency
  • Penetrates biofilm due to its low oxidation characteristic
  • Is not corrosive to metal surfaces like traditional free chlorine and bromine
  • Is non-foaming

Kurita NT Technology Product Range:

Is an in situ generation system designed for large systems.
Based on Kurita® NT Stabilizer and Kurita® NT Active. The two components are dosed directly at the application site utilising a dosing system specifically developed for this purpose.

Kurita 7470
Is a fully formulated ready to use product designed for small and medium sized systems.

Benefits of Kurita NT technology:

The Kurita® NT system is a highly effective and patented system developed by Kurita for biofilm control in cooling water systems.
