The effect of pH on the survival of leptospires in water One of the factors on which the incidence of leptospirosis is dependent is the survival time of shed leptospires in surface water or soil water, and this t... CEC Smith,LH Turner - 《Bulletin of the World Health Organization》 被...
Positively charged filter media were used to recover bacteriophage f2 and poliovirus 1 from tap water at ambient pH level 7.8 without added multivalent cations. Recoveries from 201. vol of water with Carlson-Ford type 4 asbestos filters averaged 65% for the phage and 68% for the poliovirus ...
water treatment. Lime milk is dosed (about 10.0 mg/L) to the water in the chambers, which is directed to horizontal settler raising the pH. The retention time in the settlers is several hours. The next step involves filtration of water at a speed of 1.5–3 m/h and the final ...
People often take their drinking water for granted, but when you’re traveling the tap water may not be safe to drink.
In addition, internal degradation of metal pipes and plumbing equipment can lead to increased concentrations of metal compounds in water. Not all metals experience the same corrosion mechanism, but overall, water with low pH, high dissolved oxygen, very high temperature and high levels of dissolved...
