A new assay for determining the relative cell wall porosity in yeast based upon polycation-induced leakage of UV-absorbing compounds was subsequently developed. The term disinfection is the process of destroying or preventing the growth of disease-carrying microorganisms. But what does this really mean? Solar radiation is essential to life on Earth, but its UV component may also damage both living organisms and non-living matter. Dissolved oils are the polar constituent organic compounds in produced water, while small droplets of oil suspended in the aqueous phase are called dispersed oil [6, 10, 15]. Find out why physical disinfection, specifically through UV light, is the safest, most effective way to disinfect your water. After the tertiary treatment process (UV disinfection/ Membrane tank), the mass of microplastics in the effluent was 8.4 kg and 1.96 kg per day, respectively.
