Problems and solutions summary per category

Water Treatment

Boiler Water Treatment:

Problem

Solution

Product

Scaling and corrosion to the boiler systems

Conditions boilers and protects against the 4 elements of the boiler water: boiler pH, hardness scale, condensate pH & boiler coagulant – suitable for boilers up to 35 bar pressure

Scale formation

Prevents scale, hardness by removing particles during blowdown. Alkalinity controls corrosion. Protects three elements of boiler water treatment. Suitable for low-pressure boilers

Fully Coordinated and High-Pressure Boilers:

Problem

Solution

Product

Oxygen caused by low water temperature and high dissolved oxygen

Increase water temperature between 80 to 85°C, add oxygen scavenger and remove the dissolved oxygen

Condition the boiler to reduce the scale deposits in all boilers and all pressures

Condition hardness salts for blowdown. Maintains optimum pH, alkalinity and prevents corrosion and scale build-up

Scale deposits caused by excess of hardness salts. Scale also increases fuel operation

Maintains the boilers’ optimum phosphate levels to avoid scale and corrosion

Corrosion in feed water and condensate systems as a result of dissolved oxygen

Boiler steam is the only way to maintain acid and neutralise pH on the condensate
