In key biochemical process stages such as wastewater treatment aeration tanks, aerobic tanks, and anoxic tanks, Yosemitech Y504-A dissolved oxygen sensor enables round-the-clock real-time online monitoring, accurately capturing dynamic changes in dissolved oxygen concentration in water. Through intelligent linkage with aeration blowers and aeration control systems, it can automatically adjust aeration volume and oxygen supply intensity via variable frequency control based on real-time DO data, precisely maintaining the dissolved oxygen within an appropriate range and steadily regulating the growth, metabolism, and microbial activity of aerobic bacteria. This not only efficiently promotes the decomposition and degradation of organic matter in water but also ensures the stable and efficient operation of biochemical reactions such as nitrification and ammonia nitrogen conversion, continuously optimizing the effectiveness of biochemical treatment processes and supporting consistent compliance in wastewater treatment.

Advantages of Y504-A optical dissolved oxygen sensor

- No electrolyte required, no frequent maintenance

Abandoning the electrolyte and membrane structure of the traditional membrane electrochemical probe, there is no need for fluid replacement or membrane replacement, reducing the frequency of consumable replacement and manual inspection, and suitable for harsh wastewater conditions.

- Strong anti-interference ability, high stability

Not affected by impurities such as salts, turbidity, hydrogen sulfide, and organic matter in the wastewater, and not easily affected by flow rate. It can still measure accurately and stably in highly polluted and highly impure industrial wastewater.

- No consumption, no oxygen consumption, more accurate measurement

The optical fluorescence principle does not consume dissolved oxygen in the water body, does not cause measurement errors due to the oxygen consumption of the probe itself, and has higher measurement accuracy in low-concentration DO scenarios than traditional membrane probes.

- Fast response speed, compatible with automatic control

The signal response is sensitive and has a small lag, can quickly reflect DO fluctuations, perfectly matching the frequency linkage and automatic control system of aeration fans, achieving intelligent closed-loop control of the process.

- Anti-pollution, self-cleaning suitable for wastewater scenarios

The probe can be equipped with a self-cleaning scraper device, effectively resisting the attachment of wastewater sludge, algae, etc., reducing scaling pollution, and having a small drift and long calibration cycle during long-term online use.

- Long service life, lower comprehensive cost

The sensing membrane has a long service life, no easily consumable and non-depletable materials, no need for continuous purchase of accessories during long-term operation, and compared with traditional electrochemical dissolved oxygen probes, the total life cycle usage cost is lower.
