Condensate polishing treatment system consumes a large amount of desalted water

which accounts for more than 50% of the total desalted water consumption in power plants

and the acid-base wastewater produced in the process of equipment regeneration is also an important source of high salt wastewater. The ratio of water consumption can be sharply reduced by increasing the cycle water production and decreasing the self water consumption. Xi'an Thermal Power Research Institute Co.

Ltd. Has developed a new technology for water saving

emission reduction and consumption reduction of condensate polishing treatment system

which includes the optimization technology of operation in high flowrate mixed-bed(HFMB)

the intelligent control technology of polishing treatment mixed bed

the uniform enhancement technology of water distribution in HFMB

and the reduction of chloridion concentration in regenerated waste liquid. All the above technologies can evidently increase the cycle production

reduce the water consumption ratio

save the desalinated water and fresh water significantly

and decrease the waste water discharge and consumption of acid-alkali wastewater. Moreover

these technologies can greatly decrease the cost of zero discharge and operation fees. This method of water saving in process has been successfully used in more than thirty power plants in China. It is a low cost water saving method and has good popularization and application prospect.
