We offer solutions to meet virtually any disinfection need, large or small, and have an experienced sales and customer support team to help meet any challenge.

Water treatment disinfection systems use chemical methods to attack and eliminate bacteria (fungi, bacteria) and viruses. The processes of these systems are different from preservatives, which do not allow microbial material to spread by various means without destroying them completely. Water disinfection is an essential element in the production of high quality water, which can be used for reproduction or other purposes.

Water disinfection is the process of killing pathogenic microorganisms harmful to human body in urban water treatment system. In the urban water supply system, the water supply plant of the ground water source (the inflow from the underground water source is generally treated by simple precipitation or directly sterilized) in the water by coagulation precipitation, filtration, can remove a lot of bacteria. Generally speaking, coagulation precipitation can remove 50-90% of coliform bacteria in the water, and filtration can further remove about 90% of Escherichia coli in the water, but far from the requirements specified in the water quality standards for drinking water (qualified indicators for disinfection of drinking water is less than 3 Escherichia coli in 1 liter of water). At this time, the water still contains about 100 coliforms, so it needs to be sterilized. There are many methods of water disinfection, often used chlorine disinfection, ozone disinfection, ultraviolet disinfection and so on. According to these disinfection methods, there are chlorine dioxide system, ozone generator, sodium hypochlorite generator, ultraviolet disinfection system and so on.

Ultraviolet disinfection system uses the principle of ultraviolet disinfection, modular design, the size and dose of the module with the different treatment capacity and water quality and custom design, the disinfection module is placed in the disinfection channel, together with other parts on the shore and PLC control unit constitutes the disinfection system.

Ultraviolet disinfection system is generally composed of seven parts:

  1. ultraviolet lamp module;
  2. junction box;
  3. Ballast control cabinet;
  4. PLC main control cabinet (man-machine interface box);
  5. Pneumatic device and air compressor;
  6. lifting device;
  7. overflow weir and related auxiliary accessories

Commonly used disinfection methods are divided into physical disinfection method, chemical disinfection method and biological disinfection method.

  1. Physical disinfection method: it refers to the method of killing or eliminating pathogenic microorganisms and other harmful microorganisms by physical factors. Its characteristics are rapid action, disinfection items do not leave harmful substances. The commonly used physical disinfection methods include natural purification, mechanical sterilization, thermal sterilization and ultraviolet radiation.
  2. Chemical disinfection method: refers to the method of disinfection with chemicals. Chemical disinfection method is easy to use and does not require complex equipment, but some disinfection drugs have certain toxicity and corrosion. In order to ensure disinfection effect and reduce toxic and side effects, the required conditions and instructions for use must be strictly followed.
  3. Biological disinfection method: is the use of some organisms to eliminate pathogenic microorganisms. It is characterized by slow action, limited effect, but low cost. It is mainly used in the sanitary treatment of waste and excreta. Commonly used methods include biological thermal disinfection technology and biological oxidation disinfection technology.

Disinfectants can be classified in various ways, such as according to their chemical composition and disinfection effect. Most disinfectants can be divided into four types according to their disinfection effect, such as disinfectants that kill health, disinfectants with high efficiency, disinfectants with medium effect and disinfectants with low efficiency.

  1. killing disinfectants: including formaldehyde, glutaraldehyde, ethylene oxide, etc., can kill all microorganisms, to meet the sterilization requirements;
  2. high efficiency disinfectant: including such as peracetic acid, chlorine dioxide, sodium hypochlorite, dichlorodimethyl ethyl lactam, etc., can kill all bacterial propagules, viruses, fungi and spores;
  3. medium effect disinfectants: including ethanol, chlorhexidine, iodophor, etc., can not kill bacterial spores, but can kill bacterial propagules, fungi and most viruses;
  4. inefficient disinfectants: including benzalkonium bromide, benzalkonium chloride, phenol, etc., can kill most bacterial propagules, some fungi and viruses, but can not kill bacterial spores, tuberculosis bacilli and some fungi and viruses.

Different disinfectants are suitable for different occasions. For example, inactivated disinfectants should be used for sterilization in operating rooms and medical equipment, high-efficiency disinfectants are often used in medical places, medium-effect disinfectants are commonly used in skin disinfection, and low-efficiency disinfectants are often used in wound cleaning.
