Clean water is a necessity for all of us. Despite being a necessity, some 1.1 million people are estimated to fall ill each year from drinking water that has not been properly treated. Many people depend on tap water for their livelihood. However, due to water pollution and soil contamination, tap water can in some cases carry harmful pollutants such as bacteria and viruses, as well as harmful metal components. As a result, household water treatment has been changed from being optional to being required. Household water treatment

Wastewater treatment has never been so crucial since it more and more comes from many sources today. So many factories, especially those in chemical, printing and dyeing, electroplating industries, produce a great deal of wastewater. In agriculture, harmful ingredients of pesticides flow from farms into rivers that used to supply fresh water for people’s life. Even in everyday life, domestic wastewater is produced every day. The harmful ingredients in various cosmetics products, washing products can easily enter the sewer, and may be further discharged into rivers or groundwater.

Although the Earth is rich in fresh water resource, it is not inexhaustible. Moreover, the distribution of fresh water resources is uneven in time and space. The vast majority of fresh water is found in the North and South poles of the Earth. The fresh water that can be used by us mainly comes from rivers, lakes and groundwater. Urbanization, a growing population and climate factors are all contributing to the increased demand for fresh water. According to statistics, 30% of the world's population lives in areas of

In the food and beverage production industry, the pursuit of hygiene and health is always the goal. With today's increasingly serious water pollution, people's attention to the water safety in the food and beverage production industry is also increasing. In the municipal water supply system, it is difficult to completely handle all the water since there will always be inevitable dead corners in the sterilization process. And water is often so easily to be contaminated by various microorganisms. The food and beverage production industry has an irreplaceable demand

Tap water must be pure. However, with the discovery of more and more sources of water pollution, our demand for water purity is higher than ever before. Insufficiently purified tap water can contain a variety of bacteria, viruses, and other harmful microorganisms. There are many water sterilization methods including precipitation, filtration, adsorption, distillation, boiling, chlorination and UV treatment. Among these methods, chlorination and UV water treatment are the most commonly applied solutions for the purification of tap water for family use. Problems Associated with Chlorination Chlorination treatment has

In 1976, a mysterious disease broke out in Philadelphia, USA. 221 people fell in ill, in which 34 people died later. In 1977, the disease had been known as legionnaires' disease because it affected veterans. Later, research revealed that the bacterium that causes the disease was found to be a previously unknown type of bacteria. As a result, the disease was subsequently named Legionellosis. This is a type of atypical pneumonia caused by legionella. Humans get the disease mainly by drinking bacteria-infected water. The main physical symptoms are

Ballast water is specially injected into the ship to maintain the ship's balance, adjust the position of the ship's center of gravity and the distribution of weight. Ballast water is stored in the ballast tank of a ship. For a ship without cargo, the right amount of ballast water is conducive to keeping the ship at a proper depth of immersion to ensure the normal operation of the propeller. In addition, the fuel consumption of the ship during the voyage will bring weight reduction and the rise of

As people pay more attention to the problem of water pollution, a variety of water treatment solutions is increasingly appearing in our homes, communities, factories and many industries. In our homes, whether the water used is tap water or from private well, a set of water treatment equipment can effectively ensure the safety. For communities or factories, an efficient water treatment system can not only realize the treatment of wastewater, but also realize the efficient reuse of water. Among so many types of water treatment systems, ultraviolet has

With higher requirements for food safety today, liquid sugar is required to be produced according to stricter quality standards. In the production of liquid sugar, although the concentrated syrup itself contains high osmotic pressure, which prevents some bacteria and microorganisms from reproducing. But such pressure doesn't have much effect on microorganisms that exist in the form of spores. What's more, they reproduce more quickly when the syrup is diluted. Problems caused by the accumulation of bacteria and microorganisms include odors, color changes, and shortened shelf life. This will

Swimming pool UV sterilization has become an inevitable trend with people’s growing concern of water-borne infectious diseases. In recent years, the emergence of health regulations for swimming pools has led to the consideration of further improvement of the water quality. Using UV light to sterilize swimming pools is a major step forward over the previous use of halogen ingredients such as chlorine and bromine. Commercial pool operators and residential pool owners are increasingly turning to UV water treatment equipment because chlorine-resistant microorganisms such as Cryptosporidium and Giardia are
