Water Ec Tester Series

In today's society, water is a basic substance for human life and economic development, and its importance is self-evident. From daily drinking to industrial production and agricultural irrigation, the quality of water is directly related to people's health and sustainable development of the industry. The water quality monitoring industry has also shouldered a heavy responsibility and become a key line of defense to protect the safety of water resources. ​
However, the rapid development of modern social economy is bringing many difficult problems to water quality monitoring. On the one hand, emerging pollutants continue to emerge, such as microplastics and drug residues, and traditional monitoring technology is difficult to capture their traces, and it is urgent to develop new detection methods. On the other hand, with the expansion of cities and changes in industrial layout, the scientific nature of the layout of water quality monitoring points has been challenged, and some areas have insufficient monitoring coverage, which cannot timely and comprehensively reflect the dynamics of water quality. ​
Faced with these challenges, the industry actively explores innovative paths. In the field of technological innovation, scientific research teams have increased investment to develop monitoring equipment based on cutting-edge technologies such as nanotechnology and biosensors, greatly improving the detection accuracy and efficiency of trace pollutants. At the same time, with the help of Internet of Things technology, an intelligent monitoring network is built to realize real-time transmission and analysis of monitoring data, effectively make up for the shortcomings of insufficient monitoring points, improve the overall monitoring efficiency, provide solid support for the scientific management of water resources, and ensure that high-quality water sources continue to benefit society.

At a time when the world is paying more and more attention to environmental protection, the importance of water quality monitoring is self-evident. However, its development has encountered many bottlenecks. On the one hand, the uneven distribution of monitoring points and the insufficient number of monitoring points cannot fully and accurately reflect the water quality of the water area. Taking a large lake as an example, only a few monitoring points are set up sporadically around it, and the center of the lake and other areas have been in the monitoring blind spot for a long time. Once the water quality is abnormal, it is difficult to detect it in time. On the other hand, the aging of monitoring equipment and lagging technology have resulted in poor detection capabilities for trace pollutants and emerging pollutants. For example, some old sensors have extremely low detection sensitivity for some new pesticide residues, which cannot meet the increasingly stringent monitoring needs. At the same time, the massive monitoring data lacks unified standards and effective sharing mechanisms, forming "data islands" with low utilization rates. ​

In response to these thorny issues, industry experts and relevant departments have taken active actions. In order to optimize the layout of monitoring points, multiple departments such as water conservancy and environmental protection have jointly conducted research and scientifically planned additional monitoring points based on factors such as water functions and water flow directions. In terms of technological innovation, we will increase capital investment and encourage enterprises to develop new monitoring equipment, such as high-sensitivity sensors made of nanomaterials, which have greatly improved detection accuracy compared to traditional equipment. In terms of data management, we will start to build a national water quality monitoring data sharing platform to break down data barriers between departments and regions, promote data circulation, provide strong support for water quality management decisions, and help the water quality monitoring industry reach new heights.

Industrial waste water is discharged during the production process.it is an important cause of environmental pollution, especially water pollution. Therefore, industrial waste water must meet certain standards before discharged or enter the sewage treatment plant for treatment. Industrial waste water discharge standards are also classified by industries,such as paper industry,oily wastewater from Offshore Oil Development Industry, textile and dyeing waste water,food process,synthetic ammonia industrial waste water,steel industrial,electroplating waste water,calcium and polyvinyl Chloride industrial water,coal Industry,phosphorus industry water pollutant discharge,calcium and polyvinyl chloride process water,hospital medical wastewater,pesticide wastewater, metallurgical wastewater Industrial wastewater monitoring and testing parameters:PH, COD, BOD, petroleum, LAS, ammonia nitrogen, color, total arsenic, total chromium, hexavalent chromium, copper, nickel, cadmium, zinc, lead, mercury, total phosphorus , chloride, fluoride, etc. Domestic wastewater testing test: PH, color, turbidity, odor and taste, visible to the naked eye, total hardness, total iron, total manganese, sulfuric acid, chloride, fluoride, cyanide, nitrate, total number of bacteria, total large intestine Bacillus, free chlorine, total cadmium, hexavalent chromium, mercury, total lead, etc. Urban drainage waste water monitoring parameters: Water temperature (degrees), color, suspended solids, dissolved solids, animal and vegetable oils, petroleum, PH value, BOD5, CODCr, ammonia nitrogen N,) total nitrogen (in N), total phosphorus (in P), anionic surfactant (LAS), total cyanide, total residual chlorine (as Cl2), sulfide, fluoride, chloride , sulphate, total mercury, total cadmium, total chromium, hexavalent chromium, total arsenic, total lead, total nickel, total strontium, total silver, total selenium, total copper, total zinc, total manganese, total iron, volatile phenol, Trichloromethane, carbon tetrachloride, trichloroethylene, tetrachloroethylene, adsorbable organic halides (AOX, in terms of Cl), organophosphorus pesticides (in terms of P), pentachlorophenol.

Drinking water safety is clearly a critical priority.Yet the number of threats to water safety continues to grow daily, and include animal and human waste, improper disposal of chemicals, pesticides, and deep earth injection of hazardous materials. Contamination is also a threat due to improper water treatment and disinfection procedures, as well as from poorly maintained water distribution systems.

The Safe Drinking Water Act, has established national health-based standards that address both man-made and naturally occurring contamination. Compliance requires consistent, accurate measurement of water parameters performed in the lab, field, and online. While many measurements can be made in the lab, key variables such as pH, conductivity, fluoride, and chlorine can also be measured online in real-time to warn immediately if limits are exceeded.

Usually there is four steps for drinking water process
First step is Pre-treatment for source water
Second step is Filtration
Third step is disinfection process
Fourth step is distribution ,we have to measure pH,turbidity,hardness,residual chlorine,conductivity(TDS),then we can know the potential risks or threaten to public heath on time.the residual chlorine value should be over 0.3mg/L when be piped out from drinking water plant, and over 0.05mg/L at end of pipe network.turbidity must less 1NTU,pH value is between 6.5~8,5,pipe will be corrosive if pH value is less 6.5pH and easy scale if pH is over 8.5pH.

At present online water quality monitoring system can monitor water quality 24 hours and real time.it also provide quickly and correct information to decision-makers based on water quality changes in real time,Thereby providing people with healthy and safe water quality.
