Importance of sewage pH testing

Monitoring of pH value is a very important measurement item in sewage plants.In daily sewage testing projects,pH value is carried out as a routine test.Continuous real-time monitoring of pH value in sewage plants is very necessary, because the pH of sewage will affect the living environment of microorganisms in activated sludge. The large changes in pH value in sewage are also one of the indicators for judging environmental factors.

DPH790 online digital pH sensor

The DPH790 online digital pH sensor dedicated to sewage treatment plants uses a reliable and anti-interference digital signal with built-in RS485 communication, which can convert the sensor's own measurement signal from analog to digital, ensuring that it can work in areas with long-distance cable laying and possible interference.In addition, the advantage of digital sensors is that they do not require a transmitter and can be directly connected to other industrial control equipment such as PLCs, computers, and data loggers to obtain data directly. This digital pH sensor can also store calibration data, making it plug-and-play. There is also a temperature sensor on the sensor head, which can measure the temperature of water quality in a timely and rapid manner, respond quickly, and can also realize automatic temperature compensation. The entire digital pH probe is made of PPS material, which is corrosion-resistant and will not rust in a sewage environment. Usually the pH value of sewage plants should be controlled in the range of 6 to 9. If it exceeds this range, it will have adverse effects on the physical, chemical and biological treatment of sewage. Especially when the pH value is lower than 6, acidic wastewater will corrode the sewage treatment equipment.

The principle of digital pH sensor

Thanks to high accuracy and stability, as well as convenient communication, digital pH sensors are widely used in processes such as sewage treatment plant inlets and outlets, sedimentation tanks, and biochemical reaction tanks; in the municipal water supply industry, surface water, aquaculture and other industries pH monitoring and online pH monitoring of various industrial production process water and wastewater treatment processes. This DPH790 online digital pH sensor for sewage has a protection level of IP68 and can work continuously in water.The split lead design makes installation and replacement easy.
