Boiler water treatment; Industrial boilers and steam raising plant are used extensively in many commercial, manufacturing and industrial processes.

To ensure that such boiler systems are correctly maintained and operate at optimum efficiency it is essential that the correct boiler water conditions are maintained at all times. This can be achieved dosing selected boiler water treatment chemicals into the feed water.

Aquatreat’s technically advanced boiler water treatment chemicals have been scientifically formulated to improve the operation and maintenance of industrial boiler systems and steam generation plant by proactively managing the problems associated with the use of water including scale formation, metallic corrosion, boiler water carryover and sludge deposition.

Our high performance boiler water chemicals include single-shot multifunctional treatment products, scale and corrosion inhibitors, oxygen scavengers, alkalinity builders, sludge conditioners, condensate line treatments and more.

Boiler Oxygen scavengers

Boiler corrosion control; Oxygen-related metallic corrosion is a significant issue in the operation and maintenance of industrial boiler systems and steam raising plant.

To ensure that such boiler systems are well maintained and operate at optimum efficiency it is essential that the correct water conditions are maintained at all times. This can be achieved using carefully selected oxygen scavengers designed specifically for steam boiler corrosion control and feed water corrosion control in steam raising plants.

Aquatreats technically advanced boiler water oxygen scavengers are scientifically formulated to combat the detrimental effects of oxygen-related corrosion in industrial boiler systems, hot water systems, and steam raising plant and so help reduce maintenance costs, maintain boiler efficiency and extend plant and equipment life.

Steam Boiler Corrosion Control

Preventing Boiler Corrosion is done through the removal of oxygen and maintaining appropriate alkalinity levels in the boiler water to prevent acid attack.

Boiler condensate corrosion

Condensate corrosion control; The protection of steam boiler condensate lines is an important issue affecting the operation and maintenance of industrial boiler systems and steam raising plant.

To ensure that such steam boiler systems are well maintained and operate at optimum efficiency it is essential that the correct water conditions are maintained at all times. This can be achieved using carefully selected chemicals for the protection of condensate lines in steam boilers.

Aquatreats advanced technology steam volatile condensate line treatment chemicals have been scientifically formulated to protect condensate pipe work in steam boiler systems from the detrimental effects of acidic and oxygen corrosion caused by the steam condensate.

Boiler scale Inhibitors

Boiler scale control; Scale is caused by the accumulation of hardness salts in the boiler water which, if not removed can cause localized overheating, reduced heat transfer efficiency, and in severe situations tube failure.

Hardness salts can either be removed before they enter the boiler system or they can be treated inside the boiler itself with suitable antiscalant/scale inhibitors. Even when hardness is removed from the make-up water it is important to use an appropriate scale control programme within the boiler water to ensure that any hardness slippage is prevented from causing troublesome deposits.

Silicate Scale Prevention

Silicate scales can easily be formed in boilers at moderate temperatures and pressures. They are particularly likely where the feed water silica content is a high proportion of the dissolved solids and the feed alkalinity is low.

Due to their clingy nature and low thermal conductivity, silicate scales can be particularly damaging and should be prevented by adopting all of the following measures:

1. Adequate pre-treatment such as lime softening, ion exchange and reverse osmosis.
2. Maintain adequate phosphate or carbonate reserve
3. Maintenance of a silica caustic alkalinity ratio of 0.4 : 1
4. Limitation of the boiler water silica level down to 0.02ppm

Boiler Alkalinity Builders & pH Control Agents

The control of boiler water pH and alkalinity levels are important issue affecting the operation and maintenance of industrial boiler systems and steam raising plant.

To ensure that such boiler systems are well maintained and operate at optimum efficiency it is essential that the correct water conditions are maintained at all times. This can be achieved using carefully selected alkalinity builders designed specifically to control pH in boiler water systems.

Deposition causes & remedies

The precipitation and deposition of hardness salts in feed water to low pressure boilers is commonly a result of raising the feedwater temperature or the pH value. The later problem should be avoided by the use of alkalinity builders dosed into the boiler shell.

Offending hardness salts should be removed only by softening the make-up water (or the feed water if condenser leakage is the source of contamination).

Acid Attack

Acid attack in a boiler can be caused by low make-up feed water pH which attack the metal surfaces within the boiler system either causing a generalised thinning or localised corrosion of high-stress areas. Be aware that the feed water can also become acidic through contamination in the system (process contamination of condensate or cooling water contamination from condensers). To remedy this your treatment regime should include the maintenance of appropriate boiler water alkalinity making sure not to reach excessive levels as this may cause carryover.
