1. Immunity: The body's shield of defenseImmunity is the body's important line of defense against foreign pathogens and internal abnormal cells. It involves identifying and eliminating foreign bodies such as viruses and bacteria, dealing with aging, damaged, dead, and degenerated cells, and identifying and dealing with mutant cells and virus-infected cells in the body. A strong immune system is the cornerstone of a healthy life.2.

When treating drinking water, chlorine gas and its compounds (such as hypochlorite and chloramines) are widely used for disinfection, and chlorine gas oxidation is also employed to improve water quality in cases of severe water pollution. Currently, over 80% of water treatment plants globally still utilize chlorination as the primary method for microbial disinfection. However, excessive residual chlorine in water not only produces unpleasant odors and affects taste but also poses potential health threats to humans.

1. **Silicon and Metasilicic Acid Silicon (Si)**, being the second most abundant element in the Earth's crust, is recognized by the World Health Organization as an essential trace element for the human body. Silicon generally exists in nature as complex silicates or silica. In water, silica can combine with water molecules under specific conditions to form soluble metasilicic acid (SiO₂·H₂O) and orthosilicic acid (SiO₂·2H₂O).

The recently concluded Dubai International Water Treatment Exhibition (WETEX 2024) brought us substantial gains. The theme of this exhibition focused on the latest technologies in the water treatment industry and future development trends, providing a platform for in-depth communication among attendees.At the exhibition, we actively participated in several forum activities, listening to industry experts share insights and learning about the latest water treatment technologies and market dynamics.

Chlorine in water is used as a disinfectant by many municipal water treatment facilities. Its primary purpose is to kill or inactivate harmful bacteria, viruses, and other microorganisms that can pose serious health risks to humans.

Condensing gas water heaters, boilers, and similar equipment are efficient and energy-saving thermal devices. They utilize the heat generated by gas combustion to heat water or other mediums and improve thermal efficiency by recovering latent heat from flue gases through a condensing heat exchanger. However, during the operation of condensing equipment, some issues arise, one of which is the discharge of acidic condensate water.Acidic condensate water refers to the liquid water formed when water vapor in the flue gas condenses on low-temperature surfaces in the condensing heat exchanger.

High-end floor-sweeping robots and floor-washing machines are able to achieve comprehensive antibacterial functionality thanks to the use of high silver ion antibacterial modules in their water tanks. This technology ensures that they do not introduce new pollutants or bacteria during household cleaning processes, thus avoiding the issue of secondary pollution.Using a high silver ion antibacterial module in the water tank enables silver ions to flow through the waterway to the floor during mopping, achieving a bacterial inhibition rate of up to 99.9% on the floor surface.

Air preheaters, as essential components in industrial systems, often generate acidic wastewater, which not only poses potential harm to the environment but also violates environmental emission standards. The pH value of industrial wastewater discharge, especially for acidic wastewater, must be adjusted to near neutral to meet stringent environmental requirements. Although traditional liquid neutralizing agents are commonly used, they are inconvenient to operate, prone to human error, and may cause secondary pollution.

The emergence of condensing boilers has significantly enhanced the thermal efficiency of gas boilers and the effective utilization of natural gas. The exhaust temperature of such boilers is typically below 50℃, so the water generated from burning natural gas often exists in liquid form, commonly referred to as condensate.Strategies for handling condensate:Condensate not only contains water molecules but also a large amount of pollutants generated from combustion, such as nitrogen oxides and sulfur oxides, which dissolve in the condensate.

The 16th Shanghai International Water Exhibition came to a successful conclusion yesterday at the Shanghai National Exhibition and Convention Center (Hongqiao). As a major event in the global water treatment industry, this exhibition not only brought together cutting-edge technologies and innovative products in the industry but also witnessed the remarkable achievements of Chinese enterprises in the field of water treatment.
