For prolonged boiler life, a water treatment program is recommended. Boilers are sensitive to even minor deposits on tube walls. Therefore, most treatment programs are oriented toward scale control.
Industrial water treatment systems modify water to make it suitable for specific applications, including consumption, manufacturing, or disposal. Raw water entering an industrial plant often needs treatment to meet the high quality specifications for use in different processes.
Our range caters primarily for industrial treatment systems for water associated with heating and cooling systems and boilers of all types, which typically includes:
A total water treatment program should pursue the following goals:
Effective water treatment requires treatment before and after introduction of water into the boiler. The selection of pre-treatment option depends upon the quality of the water source, chemical characteristics of the water, the quantity of make-up feed water required, plant operating practices, etc.
After-treatment involves the addition of chemicals into the boiler water. This after-treatment is required to compensate for any variations in the pre-treatment of the boiler feed water system to assure the ultimate protection of the boiler.
Improper and non-existent feed water treatment is the major factor causing boiler failure, which ultimately results in boiler down time and costly repairs. All fresh water available from natural sources requires varying degrees of water treatment prior to use in a boiler. The composition of boiler feed water must be such that the impurities in it can be concentrated a reasonable number of times inside the boiler, without exceeding the tolerance limits of the particular boiler design can tolerate.
An effective boiler feed water treatment system works by removing harmful impurities before the water enters the boiler, and controlling the acidity and conductivity of the water. Allmech specialises in water treatment equipment and water treatment chemicals to ensure boilers operate at optimal level. Treatment methods include filtering, softening, demineralizing, deaerating and preheating.
Allmech’s unique industrial water treatment chemicals include:

Water is good at dispersing minerals and helping living things grow; water in cooling systems must be specially treated and monitored. The key is water treatment optimization, the ability to not only apply the right chemistries but also to constantly monitor and control water quality to keep it balanced at all times. By monitoring pH, water temperature, electrical conductivity, microbiological activity, corrosion, chemistry levels and other variables, your plant can be proactive.
The right program can:
To control scale, corrosion, microbiological fouling, and foam, water quality must be maintained at all times, and the right microbicides must be applied in the right doses.
Scaling in cooling water systems can be prevented using four basic approaches:
Fighting corrosion involves controlling certain water properties, including pH, oxygen, temperature, water velocity, suspended solids and dissolved solids.
Scale and corrosion inhibitors for cooling water systems protect cooling systems from the effects of scale build-up and metallic corrosion. Allmech offers a range of industrial water treatment chemicals for cooling towers:
