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.


Applicable to all kinds of small and medium-sized single-stage, double-stage reverse osmosis control system. With simple operation, complete measurement and configuration, highly integrated system


Fluorescence quenching principle, no need for internal filling, no oxygen consumption, and easy maintenance;
The service life of the fluorescent membrane cap is more than one year (under ideal conditions);
Original altitude, atmospheric oxygen partial pressure, temperature compensation, to improve the authenticity of the data;


Meter, time clock dual mode. In flow mode, the internal flow transmitter realizes the function of setting water volume as required. After setting regeneration water volume and cleaning water volume of exchange tank, the period of softening water amount (ton) according to the hardness of the raw water, each station decreases to “0” according to the set value, and stops decreasing and maintains when the water is out of service or no water.


Easily-adjustable, 5-cycle, downflow-brining control
Rugged, long-life construction features a lead-free brass valve body
Uses conditioned water for regeneration

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.


Total Chlorine (DPD) Online automatic analyzer is mainly used for real-time monitoring of water plants, secondary water supply of pipe network, medical wastewater, kidney dialysis medical water, food and beverage water, swimming pools, circulating cooling water, enterprise discharge wastewater and other occasions.


High Cost-Effective ,widely used for chemical industry,paper making industry,industrial coating,pharmaceutical,food,beverage,municipal water,Environmental and so on.
