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, in order to remove excessive chlorine in water to make chlorine less than 0.1 mg / L, and from the water to kill microbes and protect RO equipment, reverse osmosis membrane effect; 3, precision turbidity value of less than 0.2mg / l; 4, in actual operation, the optimum pH value of 6.5 to 7.5; 5, the temperature has obvious influence on the RO water permeability, the water temperature each increase of 1 ℃, water permeability increase of 2.7%, but run the water temperature can not exceed 35 ℃; 6, run the greater the pressure, the greater the amount of flooding (to the extent permitted), operating pressure is generally controlled in the range of 1.3 ~ 1.4 MPa; - pipeline direct drinking water equipment school equipment direct drinking water pipeline design (b) Three process: 1, pre-treatment includes: the original tank, raw water pump, sand filtration, carbon filtration, softening (depending on the raw water quality may be), salt boxes. The main role is raw water suspended solids, colloidal particles and other substances were removed, while the raw water turbidity, color serve to reduce the role of school drinking water equipment manufacturers in Guangdong, which can be filtered raw water to bring the particles, algae, etc. visible, if the water hardness is then preferably further increase with the water softener. 2, the host RO pure system: Reverse osmosis host system include: security filters, high-pressure pump, reverse osmosis host, the post-stage cleaning device Guangdong school drinking water equipment, finished water tank, ozone generator, ultraviolet disinfection, food-grade tubing. Security filters: filtering accuracy 5UM (m), mainly to provide conditions for the reverse osmosis water RO membranes. High-pressure pump: power equipment major high-pressure pump reverse osmosis equipment, high-pressure pump should be set high thermal protection, set up around the pump low pressure protection switch, respectively. When the high-pressure pump inlet pressure below the set value, high-pressure pump down to protect the high-pressure pump Guangdong school drinking water equipment manufacturers, after the high-pressure pump outlet pressure is higher than the set value, high-pressure pump outage Guangdong school drinking water equipment Wanted to protect the reverse osmosis membrane. RO main machine: about 0.0001 micron filtration accuracy, it is the United States in the early 1960s developed an ultra-high precision using pressure membrane separation technology. Water can filter out almost all impurities (including harmful and beneficial), only allow water molecules to pass through. Usually used for pure water, mineral water, drinking water ,, bottled water, beverage plants, food plants and other factories with pure water purification, pharmaceutical manufacturing ultra-pure water. - Pipeline direct drinking water equipment Guangzhou Tianshui (Figure) | Guangdong school drinking water equipment | Guangdong school drinking water equipment provided by the Guangzhou Environmental Protection Technology Co., Ltd.
