Optimal use condition
    Ultraviolet radiation is one type of light wave with short wavelength with small quantity of radiant energy and low penetrating power and only can kill microorganism which is under direct radiation; low water quality may directly affect the effectiveness of sterilization, therefore, double intelligent pressure differential filter is made into pre-filtering equipment for ultraviolet sterilizer, which can greatly improve the efficiency of sterilization.
