Project case details
According to the chemical industry for making chlorineand alkali,the RO system salt rejection over 97%，after polishing bed ,the resistivity more than 10 meg
PLC romote control,pre treatment equipment manual backwashMain process
The system operationcondition
This pure watersystem has been running for 2 years,the main RO equipment is stable operating,the test item in fine index.
1.the pretreatment parts:composed by sodium hypochlorite dosing equipment,fine sandfilter,activated carbon adsorb plant and 2 stage fine filter,the production water pollution index≤4，residual chlorine≤0.1ppm
The raw water directly getting from Chang jiang river,only by fast filter,the COD is high to 4.5ppm,always jam the 1 stage fine filter,then by improvement,dosing the sodium hypochlorite,bactericide,thenby fine sand filter,the water COD low to 2.5PPM,this make the replacement cycle lower from 1 month to more than 2 months,and the costs lower significantly.protect the RO system. At the same time use sodium hydrogen sulfite dosing system after 1 stagefine filter for extend the activated carbon replacement cycle.
2.RO system:compose by 2 sets 20T/H system,parallel running available,we pick up DOW membrane from the USA,additional UF water tank and membrane washing system,saltrejection more than 97%
3.mix bedsystem:composed by 2 sets D1600 diameter mix bed,one work one standby,actual production water more than 15meg
