The application of sensors in Water Treatment Solution
PH Sensor
Function: Monitoring the pH of the water body is very important for judging the stability and corrosiveness of the water quality. In the production of tap water, it can ensure that the pH value of the factory water meets the drinking standard; In sewage treatment, help control the optimal pH range of biological treatment processes to improve treatment results
DO Sensor
Function: The measurement of the dissolved oxygen level in water is a vital indicator for gauging the self-purification capabilities of water bodies and the living conditions of aquatic organisms. In the context of aquaculture, it supplies farmers with a scientific foundation for feeding and management.
Turbidity Sensor
Function:Water turbidity is quantified by evaluating the extent to which light is diffused or assimilated by suspended particulate matter in water.
It serves the purpose of tracking the variation in the turbidity of incoming water, permitting the timely modification of parameters in preliminary treatment operations such as coagulation and sedimentation. In the context of monitoring the outflow from a sewage treatment facility, it ensures that the turbidity of the discharged water adheres to the mandated discharge benchmarks.
ORP sensor
Function:The REDOX potential sensor is mainly used to measure the electrochemical balance between oxidizing and reducing substances in water, and can effectively indicate the effectiveness of disinfectants in the pretreatment and disinfection of waterworks.
In the biological treatment process of sewage treatment, it can help the operator to accurately control the aeration rate and optimize the microbial degradation efficiency; In terms of industrial water, the concentration of corrosive ions in the water can be monitored to prevent equipment corrosion.
Submersible Liquid Level Transmitter
Function: It is frequently employed for water level monitoring of natural water bodies like reservoirs, lakes and rivers. Additionally, it is also used for liquid level monitoring of clear pools and sewage ponds in urban water supply systems, thus offering data support for flood control, drought relief and water resource scheduling.
Rain Sensor
Function: The amount of rainfall has a significant effect on the quality and quantity of incoming water. Rainfall sensors can be installed near the catchment area of a sewage treatment plant to obtain rainfall information in advance. When rainfall is predicted, the wastewater treatment plant can estimate the amount of incoming water based on past empirical data and real-time information from rainfall sensors.
TDS Sensor
Function:TDS (Total Dissolved Solids) sensors serve the function of detecting the TDS value of raw water. This detection is valuable as it facilitates a swift evaluation of the fundamental qualities of a water source.
Dissolved CO2 Sensor
Function:In aqueous environments, dissolved carbon dioxide and dissolved oxygen exhibit an interconnected relationship.This leads to the occupation of a specific volume, thereby inducing a relative diminution in the partial pressure of dissolved oxygen in water and a subsequent decline in the solubility of dissolved oxygen.
Residual chlorine sensor
Function:In the industrial circulating water regime, the residual chlorine sensor is capable of effecting real-time monitoring of the residual chlorine content within the water. It serves to impede microbial multiplication and biofilm accretion, thereby precluding such issues as pipeline obstruction, corrosion and related malfunctions.
This in turn prolongs the operational lifespan of the equipment and ensures the reliable and stable functioning of the entire system.
Suspended Matter Sensor
Function:In the initial stage of water treatment, the total suspended matter sensor can be used to detect the total suspended matter content of raw water, so as to quickly assess the pollution degree of raw water.
For example, if the total suspended matter content in raw water is too high, it may indicate that the water body has been seriously affected by sediment, organic matter, microorganisms and other pollutants, which has important guiding significance for the subsequent selection of appropriate water treatment technology and determination of treatment intensity.
Water Treatment Solution Customer Case
Background:
Reservoir water quality monitoring and maintenance.
Water Treatment Solution equipment:
Numerous water quality monitoring positions are instituted within the reservoir, and online sensors are erected to keep track of parameters such as water temperature, pH value, dissolved oxygen, turbidity, conductivity and other relevant parameters in a real-time manner.
Apart from online monitoring, it is essential to perform regular comprehensive laboratory examinations of the reservoir water. This involves the detection of heavy metal concentrations in the water, the variety and quantity of organic substances, as well as microbial parameters.
Results:
The treated reclaimed water is pumped back into the aquifer through a series of injection Wells. This measure effectively prevents seawater backpouring, raises groundwater level, and improves groundwater quality.
Background:
Fresh water resources in the region are extremely scarce. In order to solve the problem of water shortage, great efforts have been made to develop seawater desalination technology, whose goal is to convert seawater into fresh water that can be used for domestic and agricultural irrigation.
Water Treatment Solution equipment:
Dissolved oxygen and ORP are important parameters for controlling microbial growth in cooling water systems. The dissolved oxygen sensor monitors the level of dissolved oxygen in the water, and the ORP sensor reflects the REDOX status of the water.
When the dissolved oxygen content in water is appropriate and ORP is in the appropriate range, it is conducive to inhibiting the growth of anaerobic bacteria. If the dissolved oxygen is too low or ORP is abnormal, it may lead to microbial growth and biofilm formation.
Results:
Chemical water is transported to fields through sophisticated irrigation systems, supporting the development of efficient agriculture. The use of desalinated sea water for irrigation has turned the originally barren desert into a high-yield agricultural area, planting a variety of crops such as vegetables and fruits, and greatly improving Israel’s food self-sufficiency rate and agricultural economic efficiency
Background:
The original treatment process of the sewage treatment plant is difficult to meet the increasingly strict discharge standards and the demand for treated water. The original sewage treatment plant mainly uses the traditional activated sludge process, which has limited effect on the removal of organic matter and nutrients such as nitrogen and phosphorus in sewage.
Weather station equipment:
A variety of sensors are installed at the inlet, including turbidity sensors, chemical oxygen demand (COD) sensors and ammonia nitrogen sensors. The turbidity sensor monitors the turbidity of the influent in real time.
When the influent turbidity exceeds 300NTU (diffuse turbidity unit), the control system automatically adjusts the dosage of coagulant in the pretreatment stage. COD sensors are used to detect the organic content of influent water, and according to their data, the difficulty of wastewater treatment can be estimated in advance. The data from the ammonia nitrogen sensor helps to control the denitrification process at the biological treatment stage
Results:
After upgrading, the treatment capacity of the sewage treatment plant has been increased from the original 100,000 cubic meters per day to 150,000 cubic meters, and the effluent quality has reached the national first-class A standard.
