How can I know if the WELLAN rings are working?
There are many ways to get to know this. One, the pressure differential between the inlet and the out let, the thermal differential also gives a clear indication of the function of the ring. Water test to check on iron content and TDS ( Total Dissolved Solids) If there is a presence of a high degree of scale in the system, the iron as well as TDS test will show a steep rise in the readings, this will level off at a certain stage, only to drop down sometime later to the content level of the incoming water from the mains. How long it will stay at the level-off stage depends upon how much scale or deposits there are in the system.
Visual inspection is a great way to determine the function of the ring. The Cooling tower will not show signs of deposit, scale, algae or oxidation. Any deposit will disintegrate and disappear so long as the CT water is in contact with the scale. The water in the holding tank will remain clear. The bacterial count will remain very low or show nil readings. In Boilers the annual inspection will show no scale, oxidation or deposits upon opening the inspection cover. Heat exchanger thermal transfer will, improve and remain at an optimum level.
There will be no necessity to clean the strainers but inspection is always necessary and recommended. The drain are a part of regular maintenance and should be carried out constantly. Normally only clean water will be seen. If the blow down is on auto-replenish device then there is not much to worry except a regular check of the real blow down water Recommended setting for the Conductivity level is 8500.
Should I stop using chemicals after the installation of WELLAN rings on a cooling tower?
No, reduce by about 20% every month.
It takes some time for Wellan oscillations to build up in the water reservoir. During this time it is important to receive chemical support to kill bacteria. Later, Wellan® will take over the task of killing bacteria without the use of chemicals. Depending on the residues, trapped in the water tower, cleaning of the drip pans and screens may be necessary.
The water in the condenser line emits foul odor?
The odor will disappear within weeks. Bio-film causing the odor and clogging will clear out. The pressure meter will show a reduction resulting in a free flow of liquid.
If I have brown/green water, will it cure the situation?
In a matter of weeks this problem will disappear.
Is one WELLAN ring sufficient for one family residential house?
Yes, installed on the inlet of the main line. In large apartment complexes it is recommended that one Wellan® ring be installed at the water mains and each on the boilers, HE/CT etc.
