Water and Wastewater Treatment Division PDF
List of problems caused by impurities in water
Problems:
- Carryover of feedwater into stream, produce Carbon Dioxide in stream leading to formation of carbonic acid (acid attack)
- Primary source of scale in heat exchange equipment.
- Causes boiler and water line deposits.
- Corrosion of water lines, boiler, return lines, heat exchanger equipments, etc. (oxygen attack).
- Corrosion occurs when pH drops below 8.5
- Corrosion
- Scale in boilers and cooling water systems
Common chemical treatment method
- Neutralizing amines, filming amines, combination of both and lime-soda.
- Lime softening, phosphate, chelates and polymers.
- Phosphate, chelates and polymers
- Oxygen scavengers, filming amines and deaeration.
- pH can be lowered by addition of acids and increased by addition of alkalies
- Chlorination
- Lime softening
