In every industry, water is used in one form or other. Water is mainly used as a cooling medium in industries for equipments like heat exchangers, compressors, radiators, chillers, spot welding guns, diesel generator sets, furnaces, condensors, etc. As we all know untreated water can cause harm to the equipments as impurities like dissolved, suspended solids shall form thin deposits in the pipelines, tubes, water passages etc., which is called scales.

These scale deposits has to be removed from the system, which otherwise, leads to harmful effects like loss of heat transfer, irregular flow of water, reduced efficiency of cooling system, breakdown and finally, lower life of the equipment. Descaling will help to remove scale deposits from the system with complete confidence, in the quickest, safest and most efficient method. The descaling methodology is explained on the following lines.

CHEMICAL DESCALING USING MAX CHEMICALS:

MAX chemicals are formulated to clean the internal heating surfaces of Heat exchangers, Compressors, Radiators – Internal, Boilers, Pipe lines, Cooling Towers, etc. of scale deposits, with complete confidence, in the quickest, safest and most efficient method. It is however extremely important to follow the procedure of known reliability under careful control as described below.

DE - SCALING USING MAX CHEMICALS IS DONE IN THREE CONVENIENT STEPS:

Step – 1 SCALE SOFTENING PROCESS :

Scale softening chemical MAX – 001 is an alkaline chemical formulated by using superior quality wetting agents. It is to be used @ 5 – 7 % of the total volume of circulating water at the time of scale softening. For example, if the system volume is 100 ltrs, 5 – 7 kgs of MAX - 001 should be added. It should be circulated for a period of about 1 hour. During this process if it is possible, increase the temperature of the circulating liquid to about 85 * C by either indirect heating or by direct steam injection. However this is not mandatory.
Drain the entire liquid after 1 hour of circulation and flush with fresh water until the PH drops to 7.0. Fill fresh water to the system to the desired level for the second process.

Step – 2 SCALE REMOVAL PROCESS :

Descaling chemical MAX – 002 has mineral acid as the base. The product has been formulated using high quality inhibitors rendering it safe for GI, Copper, MS, SS, “ O “ rings, PVC and rubber parts etc. However it is to be noted that this chemical is highly reactive with Aluminium. It is to be used @ 15 – 20 % of the total volume of circulating water at the time of descaling. For example, if the system volume is 100 ltrs, 15 – 20 kgs of MAX – 002 should be added. However, MAX – 002 should be added gradually. Add about 5 % quantity initially and keep on adding from time to time to maintain a minimum of 5 % concentration. During this process, foam generation will be noticed.

This is a sign that descaling process is progressing well. Generally it will take about 2 – 3 hours for completion of the process. Careful control should be exercised by monitoring the PH level of the circulating liquid. After foaming stops, check the PH and keep circulating. Continue this process till a stable PH value is achieved.

Drain the entire liquid and flush with fresh water until the PH comes down to 7 - 8. Fill fresh water in the system to the desired level for the third and last process.

Step – 3 PASSIVATION PROCESS :

Passivation chemical MAX – 003 is an alkaline chemical formulated with film forming inhibitors to achieve complete passivation after the descaling process. It is to be added @ 5 – 7 % of the total volume of circulating water at the time of passivation. For example, if the system volume is 100 ltrs, 5 kgs of MAX – 003 should be added. It should be circulated for a period of about half an hour. Finally the passivation chemical can be left in the system as it acts as a inhibitor.

The equipment is now ready to put back in operation.
