00:00:06.500 --> 00:00:09.500
In order to monitor the performance of a water treatment, 

2
00:00:09.500 --> 00:00:12.700
several performance indicators can be used.

3
00:00:12.700 --> 00:00:19.700
With these it is possible to observe changes in the water system 
without ever opening up pipes.

4
00:00:19.700 --> 00:00:27.700
„Delta T“ is a key figure which is used in systems in which the water’s temperature is important. 

5
00:00:28.000 --> 00:00:33.700
For example in heat exchangers or cooling systems. 

6
00:00:33.700 --> 00:00:40.200
In both systems the temperature of the water at the inlet must be different to the temperature at the outlet.

7
00:00:40.200 --> 00:00:45.900
To describe this difference in physics, we use Delta T.

8
00:00:46.000 --> 00:00:51.000
Let’s have a look at the temperature in a cooling tower:

9
00:00:51.000 --> 00:00:57.800
Warm water coming from a process is led into the cooling tower to cool down through evaporation.   

10
00:00:57.800 --> 00:01:02.200
Eventually it is led back into the process with a lower temperature. 

11
00:01:02.200 --> 00:01:10.200
When subtracting the inlet temperature from the outlet temperature, we get the temperature difference “Delta T”. 

12
00:01:10.200 --> 00:01:13.700
It is generally indicated in degrees Kelvin.

13
00:01:14.000 --> 00:01:20.700
We use this value as an indicator for the performance of our water treatment.

14
00:01:21.000 --> 00:00:24.700
Under optimal conditions Delta T remains constant.

15
00:01:25.000 --> 00:01:29.700 
Unfortunately usually circumstances aren’t perfect. 

16
00:01:30.000 --> 00:00:36.500
Deposits, incrustations and also biofilm gradually reduces the evaporation

17
00:01:36.500 --> 00:01:39.500
and thus the cooling capacity of the cooling tower.

18
00:01:41.000 --> 00:01:46.000
A good water treatment – such as the Merus Ring – is used to counteract this trend. 

19
00:01:48.00 --> 00:01:54.700
Merus reduces deposits and the incrustation of foreign substances in the pipes or cooling lamellas.  

20
00:01:54.800 --> 00:01:58.000
Existing deposits are disolved and flushed out.

21
00:02:00.000 --> 00:02:07.900
Over the long term Delta T remains constant and the cooling capacity of the cooling tower is maintained. 

22
00:02:08.000 --> 00:02:12.700
