Water Quality

Water quality testing of public facilities

As we all know, there are a lot of pollutants in swimming pool water, and the polluted water can easily become a source of transmission of some diseases, causing various discomforts to swimmers. Therefore, the use of online water quality monitoring equipment for real-time monitoring and strict filtration and disinfection of pool water is an important link to prevent the spread of various diseases, protect swimmers and improve the quality of pool water.

The swimming pool water quality online monitoring system is a data information network that integrates water quality and hygiene monitoring sensors, wireless data transmission equipment and remote monitoring platforms. The online monitoring system monitors the turbidity, residual chlorine, pH value, ORP and other data in the swimming pool through various sensors. The data of online monitoring can be displayed on the display device in the swimming pool, and the water quality of the swimming pool can be seen at a glance. For merchants, it not only reduces operating costs, but also ensures that health supervisors can maintain the water quality of swimming pools in a timely and effective manner; for consumers, it ensures their own health rights; moreover, regulatory authorities can also view data in real time through the monitoring platform. , improve the efficiency of health law enforcement.

Designed for the stringent clean working requirements of the swimming pool: Winsen places particular emphasis on safety

• The water turbidity affects the visual effect of the swimming pool and the visibility in the pool;
• The residual chlorine value reflects the sanitation and disinfection of the water body;
• The pH value can ensure the comfort of swimming.

Winsen provides OPR sensors, residual chlorine sensors, pH sensors, and dissolved oxygen sensors for the needs of various sensors for water quality testing in public facilities.

City water

When using ozone to sterilize tap water, an ozone sensor is required to detect the sterilized exhaust gas, so as to prevent the exhaust gas with excessive ozone concentration from endangering the air environment and personnel health.

In the process of using ozone to sterilize tap water, the Winsen ozone sensor module ZE03-O3 can monitor whether ozone leaks and the residual ozone concentration after disinfection, preventing ozone leakage from harming the human body, and also helping to treat the disinfection exhaust and reduce air pollution .

▲ZE03-O3 ozone sensor

ZE03-O3 adapts a three-electrode electrochemical gas sensor and a high-performance microprocessor, and can be measured with an ozone sensor. The built-in temperature sensor performs temperature compensation, which can accurately measure the gas concentration in the environment. At the same time, it has digital output and analog voltage output, which is convenient for users to use and debug, and greatly shortens the user's design and development cycle. The ozone sensor can be set according to the actual situation. different restrictions.

Water quality testing of sewage treatment

In the process of sewage biological treatment, there are certain requirements for sewage quality, water temperature, dissolved oxygen in water, pH value etc. As an important device for measuring water body data, various water quality sensors provide technical support for water pollution control and water safety in the process of sewage treatment.

Dissolved oxygen

• Too high dissolved oxygen (greater than 4mg/L) will accelerate the consumption of organic substances in sewage, and cause the aging of activated sludge and the proliferation of filamentous bacteria due to lack of nutrients in microorganisms. Long-term high dissolved oxygen will reduce the flocculation performance and adsorption capacity of activated sludge.
• If the dissolved oxygen is too low (less than 1.5mg/L), the life activities of microorganisms will be inhibited, resulting in the decay, disintegration and deterioration of microorganisms; it will affect the respiration of microorganisms and the purification ability of activated sludge, and the sludge will float and decay until swell.

pH value

The pH value will affect the charge of the microbial cell membrane in the activated sludge of sewage treatment, thereby affecting the activity of enzymes in the process of nutrient absorption and metabolism by microorganisms; changing the availability of nutrients in the growth environment and the toxicity of harmful substances.

ORP

ORP is an important direction for the development of automatic control technology and anaerobic precise control in sewage treatment plants, which is of great significance for saving energy, controlling the metabolic pathways of anaerobic microorganisms and improving the treatment effect.

• If the ORP value is low, it indicates that the content of reducing substances or organic pollutants in the wastewater treatment system is high, the concentration of dissolved oxygen is low, and the reducing environment is dominant.
• If the ORP value is high, it indicates that the concentration of organic pollutants in the wastewater is low, the concentration of dissolved oxygen or oxidizing substances is high, and the oxidizing environment is dominant.

Ammonia nitrogen

Ammonia nitrogen in wastewater refers to nitrogen in the form of free ammonia and ionized ammonium, mainly from the decomposition of nitrogen-containing organic matter in domestic sewage, industrial wastewater such as coking and synthetic ammonia, and farmland drainage. Due to the oxidation of NH4+-N, the concentration of dissolved oxygen in the water body will decrease, resulting in the water body turning black and smelly, and the water quality declining, which will affect the survival of aquatic animals and plants.

Residual chlorine

Residual chlorine means that after chlorine is put into water, in addition to consuming a part of the chlorine amount by interacting with bacteria, microorganisms, organic matter, inorganic matter, etc. in the water, there is still a part of the chlorine amount left, which is called residual chlorine. Chlorine-containing disinfectants generally refer to disinfectants that dissolve in water to produce hypochlorous acid with microbicidal activity. The high residual chlorine content is easy to kill biological activity, affecting the normal operation of the sewage biochemical treatment unit, and the poor sewage treatment effect will lead to the risk of exceeding the standard of effluent quality.

Winsen provides high-quality dissolved oxygen sensors, pH sensors, OPR sensors, ammonia nitrogen sensors, and residual chlorine sensors for water quality testing of sewage treatment species.
