Accumulation of the the aforementioned substances leads to many undesirable phenomena, such as:

* Accumulation of sediments on surfaces exchanging heat, such as plates and pipes of heat exchangers,
* Increase in corrosion events, as a result of under-sedimental corrosion, usually pitting corrosion,
* Increase in microorganism related events, such as creation of biological slime and vegetation of dangerous bacteria, such as Legionella, and others.

These phenomena lead to increased exploitation costs of circulation, as a result of lower quality of heat exchange, need for additional renovation stops and increased consumption of chemicals used for water treatment.

Sludge accumulating in a cooler

The basic method of counteracting these phenomena is bypass filtration of the circulating water. Constant filtration of as little as 2-5% of the water stream in circulation allows for effective reduction of the accumulating sediments. (In select cases it’s recommended to filter up to 10% of the stream). The most optimal bypass filtration technology, from the point of view of both investment, and exploitation costs, is disk filtration.
This is due to:

* Filters being made out of a particular kind of plastic, highly resistant to pressure, temperaturę and chemical reactions,
* Filters having a high efficiency compared to the surface of the casing, and a simple build,
* Filters having the lowest ratio of water required for rinsing compared to the filtered water produced.

Bypass filter using disk technology

AZUD disk filters offered by MCC have two additional advantages, giving them an edge over any rival solution:

* Patented Azud Helix system, which utilizes centrifugal force to allow for a longer time between rinsing, by keeping the largest particles away from the filtration module,
* Largest on the market area of a singular filtration module, spanning 1620cm2 , allowing for an increase in efficiency, without increasing the size of the device.

Comparison in water usage efficiency for different filtration methods.

In particular cases, it’s necessary to use classical filtration based on a mineral filter bed. MCC offers these as well, guaranteeing, for example, a reduction in an above-norm concentration of iron from the circulating water, both in open and closed water circuits.
