Cooling water treatment
What is a good cooling water treatment?
If the water evaporates, the foreign substances like calcium cant evaporate and remain in the water. Over time the cooling water holds more solids, which finally will settle and form limescale. These deposits can block pipes and machines and therefore might produce immense costs for cleaning. This has to be avoided and cooling water treatment of the complete cooling water system is required.
In the last years the cooling water treratment using Merus Rings in water systems, has become one of our core expertise and competence.
Where Merus water treatment can help
The cooling water is exposed to the atmosphere, because the system is open to the environment. Open systems have one or a row of cooling towers. Here the evaporation is used for cooling of the water.
Cooling systems where sea water, river water or bore well water is used for one flow through, are open cooling systems.
The water circles in the loop for a long time without being exchanged. As the cycle isn't open, the water itself doesn't have contact with the ambient air. The cooling of water is done by chillers or other kind of cooling units.
Cooling towers are the point where the classical chemical treatment takes place. This Merus can support, making the used chemicals more efficient and reduce the amount needed.
In nearly all cooling water systems our customers face the same major problems. Corrosion, fouling, scaling and deposits, as well algae and the resulting biofouling, all these cause high maintenance costs, and might cause emergency shut downs.
Traditional for each problem one special chemical is needed. We came across cooling systems where a cocktail of six different chemicals where added. The chemicals has to be continous purchased, the equipment serviced, which all adding to the cost.
Merus is able to adress all kinds of fouling (from corrosion to bio mass) in one Merus Ring. Over time deposits are flushed out. No further or far less cleaning effort is needed. Only monitoring the effect. This means we offer a long lasting solution for a good cooling water treatment.
How we can help.
In big cooling loops, sometimes we treat loops with a few kilometer of pipes, providing cooling water to hundreds of heat exchangers. In these we install Merus Rings at strategic locations. The rings are installed after discussion with the customer. In case of critical heat exchagers we place the installation directly at the beginning. Whereas in case of less important coolers, we install one Merus Ring for several of these.
To ensure the best results we also offer service agreements. They include the proper installation by one of our engineers and ongoing monitoring of the performance. The monitoring is done in cooperation with the customer. Often, existing tools and methods can be used (more).
Before installing we will analyse your system carefully, talk about blow down cycles and your processes to give our recommendation for the water treatment. We are interested in the cooling performance needed for your production. By having this close relation and understanding of your needs, we will be able to react fast, if circumstances change.
The goal is to find the perfect amount of Merus Rings installed in the ideal places in your system to gain long term success without further effort. By optimizing blow down and stabilizing the performance of the cooling, down-times can be reduced significantly. This saves costs for cooling water treatment in many ways.
