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.

ZR type double tank floating bed control valve including ZR4-1/ZR4-1S(Side Loading), ZR10-1/ZR10-1S(Side Loading). It is equiped the inlet flow Meter and drainage flow meter, All the parameters is set by water volume, The double swap tank is for Alternating regeneration. Continuous water production, Water quality is stable , Adapted to the to high hardness water softening, such as the steam boiler and heating engineering and production process water.

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

This series of brine valves have overcome the deficiency of the products existing in the market. It can not only protect water injection and check the air, but also can limit the extreme amount of water injection and filter the water running inside. If water injection is too fast, the liquid level inside the brine well will spill out quickly and the injection has to be shut down, which will result in the insufficiency of water inside the brine tank and have bad influence upon the outcome of recycling. This kind of brine valves depends on water pressure to work. It is reliable in working and valuable in extensive employment.

Meter and time dual mode, the meter mode, its inflow meter achieved all station can be set according to the water volume demanded , as long as set by the swap of tank volume (L) backwash water and wash water, set cycle running water volume(ton), according to the set value for each station after descending to the switch when the “0”, discontinued or no water stop decreasing and maintain. This series of products have beautiful appearance, high material precision of valve body parts, good strength and high temperature resistance, and the main valve body is connected with metal inserts with good maintainability.

a. On-line analysis and process control of the oil refining, metallurgy,chemical synthesis industry process;
b. Water quality on-line analysis for the power industry, electronic industry,pharmaceutical industry, clinical equipment, food industry, beverage industry etc;
c. Online analysis and drug maintenance of the process for environmental monitoring, waste water treatment, water purification ;
d. Industry of the people’s livelihood, such as municipal water treatment, circulating cooling water, swimming pool management, scientific and technological agriculture;
e. The biological fermentation, industrial coating, chemical process experimental study.


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;

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.
