The UV light of the medium pressure UV sterilizer is multi-band,with a wavelength between 200-400nm. Ultraviolet light of different wavelengths can penetrate and destroy the nuclei of different types of microorganisms,inactivate the microorganisms and not revive.In the field of aquaculture,several problems are often encountered:
First, algae multiply too fast. Under the irradiation of sunlight, algae will multiply rapidly in water.The algae consume oxygen and nutrients in the water,thus affecting the normal growth of aquatic products.Medium-pressure ultraviolet rays can effectively solve these problems.The ultraviolet light irradiated by the medium pressure ultraviolet lamp can effectively kill the algae, and can effectively prevent its regeneration. And the whole aquaculture system adopts a circulating water system, which further prevents the regeneration of algae.
The second is the diseases of aquatic products. Medium-pressure ultraviolet light can inactivate 99.99% of bacteria and viruses in the water body, and has a high inactivation rate for the bacteria that cause aquatic product diseases (such as solitary bacteria, small melons,etc.and the ability to prevent its rebirth.Ultraviolet light disinfection is physical disinfection, without adding any chemical disinfectants,and will not cause secondary pollution of water bodies.This ensures the safety of water quality and prevents the incidence of aquatic product diseases.
The use of aquatic UV sterilizers can not only ensure the safety and health of water quality,but also prevent secondary pollution of water quality.It is one of the first choices for water disinfection and sterilization in aquaculture.
Functions of medium pressure UV light in water treatment systems
1. TOC removal
2. Disinfection and sterilization
3. Ozone decomposition
4. Removal of chlorine and chloramines
5. Purify water quality
