In the continuous development of industrial production, a large amount of industrial wastewater is produced; if not effectively treated, this waste water will cause severe pollution to the ecological environment.
When treating wastewater, we must always be aware of the quality of the water to ensure the effectiveness of our wastewater treatment measures. Automated diaphragm pressure gauges are used to check the water quality.
In applying automated diaphragm pressure gauges, it is essential to use the type of instrumentation and the characteristics of the parameters to manage them properly as well as technical modifications. Therefore, the application of automated diaphragm pressure gauges in wastewater treatment is explored.
1. Automated diaphragm pressure gauges
Diaphragm pressure gauges play a vital role in the daily treatment of wastewater as a typical wastewater treatment testing tool. In addition, many advanced scientific techniques have automated the use of diaphragm pressure gauges, saving to a large extent the manual consumption of online monitoring instruments at work.
At the same time, the effective treatment of wastewater is also achieved and effectively adjusted. Therefore, we have to combine the characteristics of the online monitoring instrument with the practical application reasonably to improve its efficiency in the operation of wastewater treatment and contribute to ecological and environmental protection.
Automated diaphragm pressure gauges are more common in industrial wastewater treatment processes. Usually, the automatic detection instrument consists of 3 components: sensor, transmitter, and display.
Among them, the sensor detects the analog quantity mainly by applying a signal. Then, the transmitter turns the signal detected by the sensor into current and sends these signals to the PLC sensor.
The display’s primary function is to detect the results online and provide easy access to the results when the staff is operating.
The sensor, transmitter, and display are closely integrated to form a whole and are inseparable from each other. Otherwise, they would not reflect the role of the diaphragm pressure gauge.
Convenient operation, accurate measurement, and clear display are all outstanding features of the online monitoring instrument.
2. The importance of diaphragm pressure gauges in wastewater treatment
Every production process in a modern wastewater treatment plant closely relates to the relevant instrumentation and its automation technology.
Manual or automatic control based on the relevant parameters allows for the adequate adjustment of the different wastewater treatment processes and other aspects, thus enabling a more comprehensive and proper use of all equipment and facilities.
In the event of deviations, adjustments are made immediately so that the quality of the wastewater treatment can be guaranteed. In addition, the automatic control and regulation of the wastewater treatment plant are made possible by the instrumentation parameters, further simplifying the workload.
With continuous monitoring and very high alarms, the instrumentation facilitates a quick response to accidental problems.
Moreover, the instrumentation is an essential condition for enabling calculation and control. Automation instruments are, therefore, crucial in the wastewater treatment system in question.
3. Analysis of diaphragm pressure gauges in wastewater treatment
Flow measurement instruments in wastewater treatment are the most widely used and most important instrument.
This meter can measure various types of data in the wastewater treatment process. It includes inlet and outlet water volumes, aeration, digester gas production, and sludge return flows.
At the same time, it can also provide data information for evaluating and assessing the economic operation of the wastewater treatment plant.
3.1 Ultrasonic flow meters
In the context of the rapid development of instrumentation technology, various ultrasonic flowmeters are mainly used in channel, pipe, and pipe clamp-on measurements.
3.1.1 Advantageous features
- Simple and easy to install.
- With an extensive range of calibers, no additional costs are incurred.
- High measurement stability.
- No pressure damage.
- No interference with fluid parameters.
- Direct output of standard DC signals, which can be easily integrated into the automation control system.
3.2 Electromagnetic flow meters
The liquid can be used as a conductor in the daily measurement process. We form a magnetic field using two coils mounted on the pipe path. Alternatively, excitation is achieved using a DC or AC power supply.
The magnetic field then acts on the liquid in the pipe to create a corresponding voltage value. At the same time, there is no direct correlation between this voltage value and the liquid flow rate distribution.
4. Practical results of diaphragm pressure gauges in wastewater treatment
An automated diaphragm pressure gauge in the application process of the wastewater treatment station of the White Water Mine has achieved a good effect. The specific performance is as follows:
- The operating status of the diaphragm pressure gauge is adjusted at any time in combination with the changes in water quality during different periods to improve the inlet pipe network.
- With the support of the detection instrument, the power factor is appropriately increased to optimize the functional characteristics of the wastewater treatment equipment.
- Effectively reduce production costs in the wastewater treatment process and strengthen the real-time detection of the operating status of various equipment.
- Timely collection of various data to avoid the increase in the amount of sludge in different seasons affecting the efficiency of the wastewater treatment station.
- Reasonable use of automated diaphragm pressure gauges and regular maintenance and repair of catchment well shutters and pipes.
5. Correct application of diaphragm pressure gauges
Automatic diaphragm pressure gauges in wastewater treatment must use solid-state circuits. It also has to be temperature compensated. It should have elemental dust and water resistance. It should be waterproof, lightning-proof, and sun-proof for outdoor applications, with a transparent enclosure.
To ensure the safety of automated online measuring instruments, they can be equipped with an uninterruptible power supply and switch, actively grounded and shielded, and protected by closed metal tubes for the instrument cables.
In summary, wastewater treatment has a profound impact on the development process of enterprises and directly affects our quality of life. Therefore, we need to promote the widespread use of online monitoring instruments.
In the future, scientific development will also involve a comprehensive optimization of their reliability, automatic monitoring in all aspects of wastewater treatment, and the availability of the parameters given by the sensors.
Problems will inevitably arise in operation, but as long as issues are addressed and attention to detail is paid, automated detection instruments will undoubtedly play an even more significant role in China’s environmental protection efforts.
