CLOSED CIRCUIT, HEATING AND CHILLED WATER SYSTEMS

closed circuit, heating and chilled water systems

Closed systems are prone to various problems if a correctly designed water treatment program is not correctly implememented. A correctly designed water treatment program should be designed to minimise the risks associated with the following:

MICROBIOLOGICAL ACTIVITY:

♦   Closed systems provide an ideal environment for the growth of certain micro-organisms. The bacteria causing severe problems is pseudomonas. Once established it can prove difficult to eradicate. Severe blockages and system corrosion can result when the bacteria counts rise. A well designed water treatment program can prevent the bacteria from colonising in the first place.

SCALE:

♦   Severe scaling can occur as a result of excessive makeup in hard water areas due to leaks. For older systems where leaks cannot be eradicated the scale can be controlled by the use of pre-treatment such as base exchange water softners.

FOULING:

♦   Fouling is a general term for any solid matter contaminating the system. This is usually scale or corrosion products that can be left over from inadequete pre commission cleaning. Fouling should be reduced to prevent blockages, further corrosion or failure of system components.

CORROSION:

♦   The entire system will be prone to corrosion and can be controlled by the correct usage of inhibiters. The selection of inhibitor will depend on the various system conditions, including metallurgy and make up water quality.

Quartlerly analysis by a water treatment specialist will mean that your system will be well monitored and any failure of the water treatment program will be observed in good time. Particularly sensitive sites or where a failure has occurred in the past may require monthly analysis.
