Detailed Description


Boiler systems uses following additives to prevent fouling, scaling and biofouling in order to optimize boiler recovery rates, improve operational efficiency of boiler and reduce problems associated

Corrosion by oxygen in the boiler can be controlled by the addition of an “oxygen scavenger” to the preboiler section of the steam generating system. It is generally fed, along with other treatment chemicals, as an aqueous solution to the feed water either just upstream or, preferably, just downstream of the deaerator, although it is sometimes added into the return lines to scavenge oxygen in the condensate.

Liquid Water is vaporized to generate Gaseous Steam through Boiler which is used in industrial processes for various applications. Since Boiler along with Condensate line not only deals with Liquid water but also gaseous steam. Hence, treatment of feed water and water inside Boiler is complex. The objective is to operate Boiler with the highest efficiency for the longest possible time. Boiler water must be treated to prevent scaling, corrosion and sludge deposition.

Scale is the precipitate that forms on surfaces in contact with water as a result of the precipitation of normally soluble solids that become insoluble as temperature increases. Some examples of scale are calcium carbonate, calcium sulphate, and calcium silicate.

Scale inhibitors are surface-active negatively charged polymers. As minerals exceed their solubility’;s and begin to merge, the polymers become attached. The structure for crystallization is disrupted and the formation of scale is prevented. The particles of scale combined with the inhibitor will then be dispersed and remain in suspension.


Scaling is concerned with the seclusion of suspended inorganic particles, such as calcium carbonate, barium sulfate and iron compounds.


Fouling is concerned with the seclusion of organic, colloidal and suspended particles. Bacteria and other microorganisms that decompose these particles will create substrates. As a consequence they will grow and develop further.

The processes that are mentioned above will cause a decrease in capacity and/or an increase of the pressure and, as a result, of the energy use.

It is very important to purify the membrane preventively. In many cases regular mild cleaning is better than cleaning periodically with an aggressive cleaning product. The membrane will than last longer.
