Alkalinity Control

Conditions hardness salts for blowdown; maintains optimum pH and alkalinity and prevents corrosion and scale build-up.

Product Description

Applications

Alkalinity Control is part of Vecom's fully coordinated water treatment programme and should not be combined with a different treatment system. It is added to boiler water to keep alkalinity at the right level, which stops corrosion and prevents calcium and magnesium hardness salts from forming — any that do form can then be removed by blowdown.

Directions for Use

For best results, dose it straight into the boiler through a Vecom by-pass pot feeder fitted in the boiler feed line.

Dosage

For untreated water, start with 200 mL of Alkalinity Control per tonne of water, then fine-tune the dose against the recommended P- and M-alkalinity control limits.

Control Limits

  • P-alkalinity: 100–150 ppm for boilers 0–30 bar
  • P-alkalinity: 100–120 ppm for boilers 30–60 bar
  • M-alkalinity: less than twice the P-alkalinity value

Standard Packing

Usually available in 25 L plastic cans and 200 L plastic drums.
