Losses Due to Scale in Heating / Cooling Surfaces:
| Thickness of scale | Increase in fuel consumption due to scale |
| ½ mm | 2% |
| 1 mm | 4% |
| 2 mm | 6% |
| 4 mm (1/8") | 10% |
| 8 mm (1/4") | |
| 16 mm (1/2") | 40% |
| 30 mm(1") | 80% |
Before adopting new treatment or chemicals one has to clean the heating surfaces by selecting proper descaling agents from experienced manufacturer.
Direct / Indirect Losses Due to Improper Descaling Agent / Descaling:
- Metal loss due to poor inhibitors.
- Corrosion of equipments.
- Uneven or incomplete scale removal.
- Accidents.
- Non-removal of scale in inaccessible passage bends and corners.
- Loss of production even after descaling due to poor descalent.
What is Biological Growth:
The Biological growth is nothing but development of various types of algae, bacteria & fungi on the wall at the cooling tower etc. Biological growth in the cooling systems is unsightly, a safety hazard to working peoples in the industry. It can cause slipperiness, development of odors, cloudy and discolored water, chloramine formation, hazardous bacterial grow1h and stubborn stains. It also minimizes the flow rate of water and cooling effect.
How and Why Biological Growth Occurs:
Biological substances, in the form of seeds, bugs etc., are universally present in the atmosphere and so present in water also. These substances when comes in contact with favorable circumstances grow rapidly, and affects badly to the human being as well as company's economy.
Types of Biological Growth (algae):
The three types of algae commonly formed are the fast - growing green algae, slow growing blue - green algae (Some times called black algae), and mustard or yellow algae. The first type is relatively easy to control because it remains suspended in the water; the letter two are more resistant to treatment because they grow on the wall where they become firmly attached by penetrating cracks, crevices and tile grouting. As with bacteria, studies have shown that algae (Particularly mustard algae) are more difficult to control.
Biological Growth Inhibitors: (Biocides / Algaecides)
Biological growths are usually controlled in industrial water systems by treatment of the water with oxidizing or non-oxidizing biocides, although several mechanical procedures are used, particularly for cooling-water systems like automated, direct cleaning, discontinuance of water flow, raises the water temperatures high enough to kill organisms etc. Although, microorganisms such as bacteria, fungi and algae are the most widespread causes of biological problems.
Most commercially formulated products include several microbicides combined with dispersants and surfactant, which aid in breaking up accumulations of slimes or algae. In contrast to chemicals used for deposit or corrosion control, microbicides, particularly the non-oxidizing type, are added intermittently to minimize the tendency of organisms to become resistant to the chemical.
What is Corrosion
Corrosion is the natural degradation of materials in the environment through electro-chemical or chemical reaction. Traditionally, the definition of corrosion refers to the degradation of metals and has not included the degradation of nonmetals such as wood or plastics.
How and Why Corrosion Occurs
Ores are mined and are then refined to produce pure metals. Corrosion occurs because of the tendency of these refined pure metals to return to a more thermodynamically stable state. That means in the presence of oxygen and water the oxides of most metals are more thermodynamically stable than the elemental from of the metal. Therefore, there is always a thermodynamic driving force for corrosion of metals. The key reaction in corrosion is the oxidation of the metal to produce metal ions and electrons.

Types of Corrosion
- The most common from of corrosion is uniform corrosion, in which the entire metal surface degrades at a near uniform rate.
- An especially insidious type of corrosion is localized corrosion, which occurs at distinct sites on the surface of a metal.
- Another type of corrosion is dealloying which has also been called parting or selective leaching. Corrosion may also appear in the form of intergranular attack.
- Corrosion also occurs as a result of the conjoint action of physical processes and chemical or electrochemical reaction. Galvanic corrosion occurs as a result of the electrical contact of different metals in an aggressive environment.
- Microbiologically influenced corrosion results from the interaction between microorganisms and a metal.
To control these types of corrosion one has to adopt following one or more techniques: chemical reduction of dissolved oxygen, pH adjustment, protective film formation with corrosion inhibitors, and dispersion of suspended solids.
Corrosion Inhibitors & Oxygen Scavengers
Corrosion inhibitors are substances, which slow down or prevent corrosion when added to an environment in which a metal usually corrodes. Corrosion inhibitors are usually added to a system in small amounts. The effectiveness of corrosion inhibitors is partly dependent on the metals or alloys to be protected as well as the severity of the environment.
Oxygen scavengers are used to prevent corrosion occurred by dissolved oxygen in water. Basically, oxygen scavengers has deficiency of oxygen atom, which it fulfills by reacting with dissolved oxygen present in water and thus nullify the adverse effect of dissolved oxygen and thereby prevents corrosion.
