  • What chemicals are used in feedwater treatment?
  • The feedwater analysis and plant operating conditions determine the kind of utilized chemicals. Application of lignin and tannin to sludge conditioning and alkaline phosphate and soda ash for precipitation of magnesium and calcium are traditional internal treatment methods that effectively prevent boiler scale and reduce water hardness.
  • What is a cooling water treatment system?
  • Cooling systems are the backbone of any power plant or industrial processes and are necessary for releasing the heat from the process or equipment. The main aspect of the cooling water treatment is to ensure the water quality according to the requirements irrespective of the type of cooling system installed.
  • What are the effective enlisted methods for circulating water disinfection?
  • As per the recommendations from Cooling Technology Institute and ASHRAE, some of the effective enlisted methods are: A routine disinfection of the circulating water is also possible by either thermal treatment or chemical disinfectants. Chlorine is the most commonly used biocide.
  • Which sulfate is used in recirculating cooling water systems?
  • In case of use of copper-based alloys, ferrous sulfate is added for the formation of a protective surface layer (VGB PowerTech e.V. 2000). In the recirculating cooling water systems, the heat absorbed from the cooling medium generally, water is released in a cooling tower.
