New Arrival Primary Reverse Osmosis Device EDI Purification Water Equipment

1, reverse osmosis pure water system according to the different source water quality using different processes. Generally water after level 1 reverse osmosis system treatment, water conductivity < 10 ps/cm, after secondary reverse osmosis system to produce water conductivity < 3 us/cm in.Reverse osmosis system by ion exchange equipment or after preparation ultrapure water, EDI equipment can make the resistance rate of 18 megohm 25 ºC (about 0.056 pS/cm).2, reverse osmosis pure water system is the core part of the reverse osmosis membrane is key to producing water quality, but the former process in reverse osmosis system (also known as the pretreatment system) is the key to stable operation of reverse osmosis system.3, pretreatment system standard configuration and function:3.1, dosing device: join the reductant, and chloride ions in raw water, protect the reverse osmosis membrane.3.2, the original water pump: the raw water pressure into the pretreatment system.3.3, the sand filter: packing for quartz sand, can remove the suspended solids in the water, impurities, rust, colloids and part of the water microbes (such as red worms, etc.).3.4, carbon filter: packing for high quality fine coconut shell activated carbon, can remove the organic matter in the water and tap water contains chlorine taste and odor, pesticide and sand filter does not remove all colloidal substances, such as membrane prolong service life.3.5, if the raw water is a high content of iron, calcium, magnesium and other metal ions of groundwater, water softening device can be used.Within 3.6, security filtering device: 5 umpp filter core, can remove all aperture in more than 5 um impurities.The pretreatment system in the above process is called RO device, main effect is to raw water pretreatment, to ensure the normal use of RO device and reaches a certain service life.After pretreatment of raw water by high pressure pump, enter the RO system, the set of RO system adopts imported membrane module, a complete set of desalination rate from 97% to 98%. In China under the condition of water quality, water can be directly meet the national drinking water standards (electrical conductivityThe < 10 us/cm) water quality.
The machine adopts the principle of tube falling film evaporation, the raw water flows evenly on the tube wall through the special distributor, greatly improving the evaporation efficiency, and adopts the special spiral separation device, can reliably remove the pyrogens and particles. The second steam antiIt is an ideal steam house water equipment for hospitals, pharmaceutical factories, electronics, scientific research and other industries.
