Equipment piping drinking water (c): RO reverse osmosis equipment operation control main parameters 1, the raw water clarification and filtration water turbidity of less than 1 mg / L; 2, softening import NaHSO3 solution was added to maintain the ORP value at 70 ~ 130 range Canton school drinking water equipment to remove excessive chlorine in water to make chlorine less than 0.1 mg / L Guangzhou school drinking water equipment manufacturers, and from the water to kill microbes, protecting drinking water RO equipment Guangzhou school equipment, anti- osmosis membrane; 3, precision filter turbidity value of less than 0.2mg / l; 4, in actual operation, the optimal pH value of 6.5 to 7.5; 5, the temperature has obvious influence on the water permeation rate of RO Guangzhou school drinking water equipment manufacturers, increase the water temperature every 1 ℃, permeability increased by 2.7%, but the operation temperature should not exceed 35 ℃; 6, the greater the operating pressure, the greater the amount of flooding (to the extent permitted), operating pressure control in general 1.3 ~ 1.4 MPa range; - pipeline direct drinking water equipment industry Tidbits: PH water and the health of our new "drinking water health standards" provisions of the water quality monitoring indicators for the 106, and PH value is only sensory behavior and general a chemical indicators, PH value is set as follows: 6.5-8.5; drinking water guidelines in 1958 the first edition of the World Health Organization provisions of PH value: 6.5-9.2; the provisions of the second edition in 1984 in the drinking water guidelines as follows: 6.5-8.5; drinking water guidelines set forth in the third edition of 2003: 6.5-8.0; in 2006 a revised version of the third edition of that: although the index is no danger to human health, however, the control parameter for water treatment or it should be considered, PH value should be controlled at 6.5-9.5.
