The presence of high levels of temporary hardness (high alkalinity) in the raw water supply feeding a highly rated package boiler can result in high blowdown rates and an associated very high level of carbon dioxide in the steam. The resultant condensate has an acidic pH and the water is very aggressive to the metals in the condensate system.
Iron fouling of steam traps, poor operation of steam traps and high cost of replacement condensate pipework can result in a significant on cost to the boiler operation. To treat this type of water related problem requires consideration be given to the PT Banyu Biru Sejati Dealkalisation/Degas/Base Exchange plant.
The reliable PT Banyu Biru Sejati standard range of Degas-Base Exchange Dealkalisation Plant effectively reduces the alkalinity and hardness salts from the water giving a water of the following composition:
Bicarbonate alkalinity - less than 5% average of the input alkalinity
Total dissolved solids reduction - approximately equal to the temporary hardness
Total hardness - less than 4 ppm
PT Banyu Biru Sejati Water Services has standard modules for:
Break tanks
Raw water and degas booster pump sets
Dealkalisation columns
Degasser towers
Acid measure tanks
pH correction and caustic sets
Softening columns
Combining the standard modular dealkalisation range with the standard softening plant range gives a fully dealkalised and fully softened water.
For plants not wishing to have acid on site for regeneration and for sites with space restrictions which limit a degasser tower, PT Banyu Biru Sejati has available a "Chloride Regenerated Anion Dealkalisation Plant".
In certain areas, where the waters contain high levels of sodium bicarbonate, PT Banyu Biru Sejati Water Systems recommends a more specialised "Split Stream Dealkalisation Plant".
