Alkalinity Control

Liquid Alkalinity Control for Boiler Water Treatment.

Product Description

Alkalinity Control is a concentrated liquid alkaline product for corrosion and deposit control in boilers.

Alkalinity Control is a specialised liquid treatment, which provides the basic alkalinity on which successful water treatment depends. It maintains alkalinity within optimum limits providing optimum conditions for hardness control to function.

Alkalinity Control assists in precipitation and blowdown of magnesium salts, assist in keeping silica in suspension, neutralises acid conditions and allows efficiency to be maintained, therefore, reducing maintenance. A simple test to determine the level of treatment.

This convenient liquid can be mixed with most treatment chemicals.

This treatment is usually used in conjunction with HARDNESS CONTROL. ALKALINITY CONTROL provides the alkaline conditions for HARDNESS CONTOL to function correctly.

Without the correct precipitation and subsequent blowdown of hard water salts, scale deposits would form. This would result in restriction in water flow, ineffective heat transfer and local corrosion. The end effect would be an inefficient boiler and ultimately component failure. Treatment stops this occurring. Corrosion due to acid conditions must be avoided.


A level or treatment is maintained by testing for P-Alkalinity. The level is determined by the pressure and type of boiler. The normal method of raising the alkalinity level is by adding the required quantity of ALKALINITY CONTROL after testing for P-Alkalinity. 0.10 Litre will raise P-Alkalinity by 100ppm per 1000litre capacity.

For optimum results dose ALKALINITY CONTROL direct to the boiler via the bypass pot-feeder installed in the boiler water feed line.

Packaging: 25 Litres
