ROC-8221 Single Stage Double Channels RO Controller
ROC-8221 is a combined control instrument of a single-stage reverse osmosis controller and double-channel on-line conductivity instrument.

ROC-8221 is a combined control instrument of a single-stage reverse osmosis controller and double-channel on-line conductivity instrument.

BSQ-MINI is widely used in metallurgical manufacturing, electric power, light industry, textile, water treatment equipment, tap water pipe network and scientific research and other industrial sectors.


1) Working Position : Service->Back Wash->Brine and slow Rinse->fast rinse->Refill softened water->service.
Downflow type .Working Position : Service->Back Wash->Brine and slow Rinse->fast rinse->Refill->service.
2) Using ceramic moving valve disk, small rotation torque.
3) Abrasion resistance of sealing surface, outstanding and long-lived deal.
4) It could be operated with pressure directly.

DR20\40\50\20T\40T Soften valve series is floating bed, all appearance and geometric parameters and parts is the same as the corresponding GR20\40\50\20T\40T, floating bed has a good water quality, to adapt high hardness of the raw water, configuration swap tank should be fine and high, runing velocity in the 30-60 m/h, but resin filling rate must be above 90%, being stable working pressure,The floating bed is not suitable for frequent starting and changing water consumption.

For complex industrial processes, sewage treatment, water reuse, environmental monitoring, industrial field control, chemical process, thermal detection and discrete control, data transmission control and remote data transmission.

Single stage RO controller used for conductivity monitoring and process program control .

Salt and water savings by using 100% capacity of the tank in service before switching to the second tank
Regenerates immediately when needed for continuous soft water
Corrosion-free fiber-reinforced polymer valve body


Measure range :TUR-6101 (0~5NTU) ;TUR-6102 (0~100NTU)
