The discharge of wastewater into the environment without proper treatment can be a serious threat to human health and the ecosystem. Strict sanitary rules and regulations governing wastewater treatment are in place worldwide.
The need for wastewater disinfection
- Health Protection: Untreated wastewater contains bacteria, viruses and other pathogens that can cause disease in humans and animals.
- Ecosystem conservation: Pollutants such as heavy metals and chemical compounds can harm water resources and ecosystems.
- Compliance with legislation: According to sanitary norms and regulations, enterprises are obliged to disinfect wastewater before discharging it.
Threats from lack of decontamination:
- The spread of infectious diseases.
- Pollution of water resources.
- Damage to ecosystems.
Decontamination with 254 nm ultraviolet light
Ultraviolet irradiation with a wavelength of 254 nm effectively destroys the DNA of microorganisms, preventing their reproduction. This method has the following advantages:
- Safety: Does not require the use of chemicals.
- Effectiveness: Kills a wide range of microorganisms.
- Environmentally friendly: Does not harm the environment.
Flow-through and submersible UV units:
- Flow-through units: Integrate into the treatment system and disinfect the water as it passes through the UV reactor.
- Submersible units: Immersed in a tank of water for limited volume disinfection.
Regulatory framework
Regulations require wastewater to meet specified biological treatment requirements. Ultraviolet disinfection is one of the recognized methods to meet these requirements.
Ultraviolet disinfection of wastewater is an integral part of meeting sanitary and environmental standards. This method provides a high degree of safety and efficiency while meeting current legal requirements.
